X Pander-3 VIC Progress

X-Pander 3 VIC Assembled PCB

X-Pander 3 VIC Assembled PCB

The wait is almost over for VIC Expansion enthusiasts.  After a significant delay, X-Pander 3 VIC units are nearing the end of assembly.  As the photo shows, only the IO2/IO3 SWAP jumpers are left to assemble.  We hope to add this to the store by the end of the week.

Given the width of VIC-20 cartridges, the finished units will have the switches located underneath the board, but will otherwise look identical.

As the picture suggests, the unit shares the same basic layout and operation as the X-Pander 64, but adds additional switches to control BLK and RAM lines.

While replenishing stock of uIEC/SD daughtercards, I decided to improve the design a bit.  Hopefully, this version will eliminate the need to offer the original daughtercard option.

Features:

  • Buttons now on side of unit, for easier access.  Buttons can now be used on C128D/C128DCR when installed.
  • Operational Mini-USB connector.  If desired, power with a small Mini-USB phone charger
  • Complete 7805-based linear regulator section available for hobbyists.  Parts are not present on the board, but should be trivial to source (2 caps and an LM7805)
  • Oversized holes at front of board to allow PCB standoff usage.  When powered via MiniUSB, standoffs can be used to level the PCB.

The new daughtercard works with all uIEC/SD versions (3.0,3.1, and 3.2).  Stock will be arriving soon.  Production boards will have sorter switch posts, for some reason, I accidentally ordered taller ones for the prototype.

Toronto PET User Group YouTube Channel

by on Apr.07, 2012, under Computer Shows

The Toronto PET User’s Group (TPUG) has placed a number of 2009 and 2011 World of Commodore (WoC) presentations online at http://www.youtube.com/TorontoPETUsersGroup.  Yours truly is in some of the 2011 ones, discussing EasyFlash 3 and ZoomFloppy.  I guess, now that presentations will be online forever, I’ll have to do a better job or presenting and ensuring all information is accurate (I think there’s a few inaccuracies in my WoC presentations).  In any event, if you’ve never met me, check out the videos and realize you’re not missing much :-).
