GEOS Support for uIEC Bounty!

by on Jun.22, 2010, under Software Development

One of the most often requested features for uIEC is GEOS support. Given that uIEC emulates a Commodore Disk Drive at the protocol level, not at the hardware level, such support is harder than it sounds. Like many applications of the day, GEOS uses a custom disk drive transfer routine (commonly called a “speeder” or “fastloader”) called diskTurbo to make drive access times more manageable. Since the normal protocol is discarded in favor of a faster variant, successful emulation requires emulating the custom protocol. uIEC uses the sd2iec firmware, which has supported a handful of custom protocols for some time (including JiffyDOS), but does not currently support the GEOS custom protocol.

That may soon change, though.  RedumLOA has created a site called “Commodore Bounty” that will allow interested individuals to fund project activities.  The first bounty is for sd2iec GEOS support, which has been funded to over $750.00 at the time of this posting.  If you are interested in seeing GEOS support on sd2iec and uIEC, please consider a donation.
