Does anyone have metrics on the throughput of transfers to/from a PC to a 7800 with a DevOS 0.2 BIOS installed? Thanks.

It's been a while since I measured it, but IIRC it was about 4kb for the normal mode (which is what was used in DevOS 0.1) and somewhere between 5 and 6kb for the fast mode of DevOS 0.2. That was for a PC using DOS though.

Okay, thanks, that was what I had thought. I am looking to build one of these with an updated DevOS bios that has some debugging capabilities. Keeping the parallel port communications, instead of switching to serial.
