I just returned from a 2102 mile roundtrip excursion to the Vintage Computer Festival – East 9.1 at InfoAge in Wall Township, NJ. Having been prevented from holding the show in 2013, the VCF-E organizers went all out for the 2014 show, supporting 2 exhibit halls and a separate speaker presentation tent. I camped out in the vendor hall with our products on display.
Though this is the first VCF-E I have attended, others remarked that this was the largest Expo they have held. Thus, I am glad I was able to participate. Unlike the other shows I have attended, VCF-E is much more structured. Vendor tables are in their own room, the mornings are dedicated to speaker presentations and vendor sales, and the show floor does not open until the afternoon. Like many of the other more recent events, VCF-E is a 2-day event (Saturday and Sunday), and they even created a special VCF University event on the Friday before the main event. I didn’t specifically count, but I was told 26 different exhibits were available for viewing in the 2 (yes, two) exhibit halls.
As you can see, I spruced up the vendor tables with some colorful tablecloths, and I brought a vintage CMD-era JiffyDOS wall poster (I purchased it from Click Here SW a few years back). I brought all of the main store items, though I left some of the more esoteric adapters and such behind as they rarely sell. Sales were not overwhleming, but were satisfactory, especially in light of the fact that most of the day’s action revolved around the “consignment” tables. I loved the consignment idea (VCF even accepts items for sale, with pricing information from the owners. They then handle the financial aspects and man the sales table, taking 15% of the sales value). One individual made over $1600 in sales through this solution. I even joined in the rush, picking up a TRS80 MC-10 and a Compaq luggable.
Concerning exhibits, there were too many to mention. I’m not that much into the 60-80’s DEC HW, but it was well represented at the show. The early microcomputer options were on display, along with some early UNIX workstation options. Closer to my world, Jeff Brace and Dan Roganti borrowed a number of uIEC/SD and 64NIC+ devices to present their “Artillery Duel”-like multi-player C64 game. The graphics and such looked awesome, but they were plagued by code issues through the weekend. They kept the loaner items in hopes of better luck during a June exhibition. Elsewhere, Michau Pleban and Rob Clarke (An
Australian Brit from Switzerland, no joke) were on hand to show off a Commodore 264, a 232, a 116, a Max Machine, and their new cartridge for it called “MultiMax”. Rob also tried to talk Bil Herd (on site over the weekend) into firing up the V364 Prototype board that Bil had delivered to Rob at the show. Rob talks more about the unit in his Youtube smoke test for the unit, but it was Bil’s dev board back in the day.
It’s not the same as being there, but here are some galleries to show what was on display and the participants who gathered in NJ:
The ninth “annualish” Vintage Computer Festival East will be held April 4-6, 2014, at the InfoAge Science Center, in Wall, New Jersey.
VCF East is a celebration of computer history from the 1940s-1980s. The schedule includes a hands-on exhibit hall, technical workshops, lectures, a marketplace, tours of the InfoAge museum complex, a dollar-per-pound book sale, prizes, more.
This year’s show will be bigger than ever. New attractions include Friday’s “VCF East University” which is a full day of technical classes. Friday attendees can win an oscilloscope courtesy of Tektronix!
The main show on Saturday-Sunday will have lectures/workshops and dozens of exhibits.
Keynotes include former IBM archivist Paul Lasewicz and IEEE 802 LAN/MAN committee founder Maris Graube. Other lectures topics include software preservation, the history of Franklin Computer Corp., and many more, all scheduled for the morning. In the workshops you can learn hands-on vintage computer repair skills or even build a working replica of something exotic.
This year there will be two exhibit halls instead of one. Exhibits open in the afternoon – imagine an antique car show, but instead of “no touching” signs, everyone has to take you for a ride! Registered exhibits so far cover everything from a real Apple 1 to the M.I.T.S. Altair to DEC minicomputers. In addition, the event’s main sponsor MARCH (Mid-Atlantic Retro Computing Hobbyists) will debut its UNIVAC 1219-B military mainframe computer, circa 1965.
Tickets for VCF East University are just $20 and include a pizza lunch. Tickets for the main show are $15/day and $25/both days. Saturday/Sunday tickets are free for ages 17 and younger. A three-day adult admission is $40.
Proceeds benefit MARCH. Official sponsors include the InfoAge Science Center, VintageTech, Tektronix, the Trenton Computer Festival, Eli’s Software Encyclopedia, and Vintage-computer.com. Archive.org, IBM, and the IEEE History Center are providing informal assistance.
• Steve Wozniak, co-founder of Apple: “Seeing the early equipment at VCF is an amazing experience. For many of us, it’s better than a museum. It touches on all the hopes and dreams of the time and the many efforts to achieve what others thought would never happen. It brings back memories of a revolution in the making. … The people you meet at the VCF are amazing.”
• Lee Felsenstein, moderator of the legendary Homebrew Computer Club and creator of the Osborne 1 portable computer: “In 35 years the personal computer grew from nothing into the most important device shaping everyday life. It should be part of everyone’s education to see how it grew and to learn from the people who grew it in ways they wanted to see it grow. VCF is the place to be where not only the equipment can be seen and tried out but, perhaps more importantly, where the people who rose to the challenge offered by these machines can be met and heard from.”
• Gordon Bell, top DEC engineer and co-founder of the Computer History Museum: “As a speaker at the first September 1998 VCF, I have been delighted to see it grow and flourish. The Vintage Computer Festival is an important institution for computing history simply by getting everyone together for collecting, sharing, and trading all form of bits. Having a forum, gathering, and market for old stuff a.k.a. vintage computers and the software that made them live is an essential way to preserve and expand the history of computing — for some of us, the greatest invention.”
• Dave Ahl, founder/editor, Creative Computing magazine: “Vintage Computer Festival East celebrates the hard work and vision of all the volunteers who have made the InfoAge Science Center –- now a National Historic Landmark — a place where one can learn from the past to live for the future. Oh, and it’s great fun too!”

This project had its start in a late 2009 discussion between Leif Bloomquist, a Canadian Commodore enthusiast and musician, and myself. Leif had been playing with a hand-built 6850-based VIC-20 MIDI cartridge designed off a 1980’s era Maplin “Electronics” article, and wondered if a production run could be arranged. I took a look at the design, and noted that the 6850 UART would be hard to source. I suggested some design changes to bring costs down, and plans were made to refine the design.
To further the design, I wired up a newer UART (16450-based) to a daughtercard that could plug into the 6850 socket on the original board. That allowed Leif to refine the software, and provide out the redesign. Once that was done and successful, we discussed a final production version. Changes included offering a built-in user-flashable ROM function.
That brings us up to late 2012. I purchased the parts for a completely new prototype board, but could not get it assembled by World of Commodore, so I brought the parts to the show and hired the assembly done.
Well, the assembly resource took longer than expected to finish the construction, but I did receive this same exact board mid-Feburary 2013. I fixed a few small design issues, only to discover the board expansion port was wired 100% backwards. Commodore, for reasons known to them only, named the pins on the VIC-20 expansion port in reverse from the industry standard. Since the prototype PCB pins were named according to the standard, every one would need modification.
I packaged up the board and sent it back to the assembler, but I must have messed up the address, as it did not arrive in a timely fashion. Since I had shipped it from the Post Office directly, I didn’t get tracking information, and thus had no idea of its location. After a few weeks, I resigned myself to the loss of the unit, and started gathering parts for a second unit to be shipped via trackable shipment to the assembler. As it turns out, the assembler and I were both planning to attend the 2013 Midwest Gaming Classic in WI, so I made plans to transfer a new set of parts during the show.
No sooner than the show ended and parts were transferred, the original package showed up at my office, undeliverable. I quickly saw the addressing issue, created a new trackable label with the correct address, and sent it on its way. Which brings us to last week, when the unit arrived, after the rewiring effort.
After all of that effort, I could now begin the potentially laborious task of debugging a “paper design”. I had designed the entire unit on paper, but had not previously proven out any of the elements on a breadboard. Though the original UART design was working on Leif’s PCB, the new design was marked different, owing to the additional decoding logic needed for the FLASH ROM. As such, it was almost a completely new design. I’m not sure if credit is deserved and who deserves it, but the UART and FLASH ROM read access worked out of the box. Bank selection for the FLASH ROM did not work, but that’s a minor issue.
And, we’re almost to the point of creating a VIC-20 MIDI production design.
I can’t claim a significant amount of creativity, but over the past few years, two folks have dropped off “VIC-Switch”-like devices in hopes that I could reverse engineer them. THese are devices used back in the day (typically in schools) to share a single disk drive or disk and printer with up to 8 computers. I long ago drew up schematics of the existing designs, but wanted to freshen up the solution instead of just creating a replica.
Well, as it goes, finding time takes time, but I decided to try my hand at a new design, and here is the current result. It’s not much at present, though I can enable/disable IEC ports, and “hold” the 64 from timing out the bus request. Yes, that’s an LCD there. I found a great price on them, and I think that’ll be in the final design. It’s only marginally cheaper than a 7 segment LED or two, and much more interactive then a few LEDs.
It’s been awhile since I developed firmware, and this gave me a chance to clean the cobwebs off my programming skills.
In the “another project that has been long in gestation” category comes a niche offering for those with Commodore SuperPET machines and a desire to run the OS/9 operating system. OS/9, a multi-tasking, multiuser, realtime OS with UNIX-like qualities, was popular in the 1980’s and ran on machines with the Motorola 6809. In addition to the small TRS80 Color Computer, the SuperPET includes a 6809, but the standard memory map of the SuperPET does not lend itself to OS/9 operation. That is where this little board comes in. Installation does not affect normal SuperPET operation, but extends it with OS/9 compatibility.
The SuperPET, a variant of the Commodore 8032 that included additional boards designed by the University of Waterloo, did not sell well, as far as I can tell, and limited (though not ultra-rare) numbers exist. Still, for those lucky enough to own one, OS/9 can truly turn the SP9000 (another name for the SuperPET) into the MicroMainFrame (another name for the SuperPET).
The project has been gestating since 2008 in some fashion. Late that year, TPUG member Golan Klinger asked if I could reproduce the SuperPET MMU board, which TPUG members created in 1985. for a possible club fundraising activity. I dutifully created a new layout of the design, and awaited next steps. Around the same time, Mike Naberezny (of 6502.org fame) started discussing the board, and we eventually compared notes. Over time, it became evident that TPUG was not going to pursue offering the unit for sale, and Mike performed a significant amount of legwork obtaining permission to replicate the software from Radisys (who purchased the OS/9 rights) and permission from TPUG leadership to offer the PCB. Thus, the majority of credit for this offering goes to Mike, who has a web site devoted to this impressive little board. I’ll put one in due time, but it won’t provide any more detail than Mike’s. I should also give a shout out to Steve Gray, who helped with information and PCB scans.
Currently, due to the low volumes, the unit will be available in kit form only for approximately $30.00. Thus, break out your soldering iron and a weekend of time to add this capability to your SuperPET!
Regrettably, I found out today that the upcoming C4 EXPO (which was going to be a all encompassing retro convention) has been cancelled for 2013. We last attending C4 EXPO in 2011 when it was held in The Drawbridge Inn in KY. In addition to the reasons given on the web site, I think the combination of the venue closure and the fact that the event was being managed by a single person contributed to the cancellation.
With the cancellation, CommVEX appears to be the next Commodore conference event. I’m not sure if RETRO Innovations can make the trip, but I am considering it. It would be nice to meet some of the west coast and southwest enthusiasts.
Sometimes, a product gets lost on the way to final production. Our QuadPortIEC 4 port IEC bus hub is one such product. After announcing the design here and showing off completed boards here, we focused our attention on the recently introduced ZoomFloppy and then the EasyFlash 3. Finally, we sent the boards off for assembly, but still felt a bare board with wires would simply not work as a product. Finally, about a year or so ago, Commodore enthusiast Jim Peters in Iowa requested some bare PCBs and assembled units for personal use, which we supplied. He took it upon himself to machine finished cases for the units, with fabulous results. Thus, we hired him to supply finished cases for the remaining stock, and now can offer them in the store.
The design has not changed; QuadPortIEC is nothing more than a “dumb” IEC hub. ATN switches on the front for each port allow “silencing” of each bus segment, but that’s the only functionality exposed.
Still, we are glad to finally put the units in the store, where they will sell for USD$30.00. Since the units fill out a small flat rate box, we may need to adjust shipping charges for buyers.
RETRO Innovations will be traveling to Brookfield, WI this weekend for the 2013 Midwest Gaming Classic. We’re simply attending, not manning a store table, but feel free to email us if you’d like to place an order for pickup and skip the shipping costs.
Since we don’t have enough things to keep us busy, we’ve been on an arcade machine buying spree over the last few months, picking up:
- a KLAX upright conversion, in great condition
- a Pole Position, in good condition, working, but missing a few sound effects
- a non working asteroids, in rough condition
- a Shoot the Bull game in a Ms. Pac Man cabinet
- Some Championship Bowling ROMSTAR game, in a Super Pac Man cabinet (purchased for the cab, monitor and wiring).
- a Gyruss, complete and working
- a Defender, with monitor issues
- a StarFire unit, in a Defender case, with PCB issues (but, partially working)
Since our goal is to see if there are product opportunities in game restoration for RETRO Innovations, buying machines that need help seemed appropriate. KLAX was a fluke, as it’s in great condition, but the others all need some TLC for optimum operation. To start that process, a trip to MGC is required. We know the Ms. Pac Man needs to be converted back, and that requires some parts (we have a known working PCB for the game already). Asteroids might be beyond help, and so might be parted out, while the Pole Position just needs some TLC on the PCB and general cleaning.
It’s an interesting exercise, and they should be fun to play… err test!
As announced this afternoon at World of Commodore 2012, RETRO Innovations has acquired the rights to offer Click Here Software’s port of JiffyDOS for the Commodore VIC-20, C16, and +4 machines, thus completing the set of JiffyDOS KERNAL replacement offerings. Within the next few days, the KERNAL replacements and image files will be available in the online store for sale. Many thanks for those customers who kept asking for the versions, as that helped show that demand still exists for these versions of JiffyDOS.
The difference between a project and a product often boils down to looks. Along with a professionally designed and manufactured circuit board, a proper enclosure completes the package.
Thought we have long offered a un-machined cartridge case with 64NIC+ Ethernet cartridges, we had resisted the thought of milling cartridge cases. In the case of the 64NIC+, the Ethernet jack machining is tough and prone to error. A proper CNC milling machine is required to efficiently handle such a design. However, the EasyFlash 3 did not require so complex a solution to correctly machine a suitable cartridge enclosure. Some simple jigs on the drill press and creative use of drill bits ably substituted for a CNC mill. As a result, EasyFlash 3 arrives in an optional fully machined enclosure.
The red color choice was somewhat arbitrary, as we have clear enclosures. Still, translucent red and the red LED on the unit seemed to fit well together. I hope you agree.
The EasyFlash 3 is now available in our online store.
