I bought the designs when the inventor graduated from college and moved to Japan. It's a bus adapter, not a PC-on-a-card like the C= A2088 boards, etc. It doesn't run DOS/Windows, it maps ISA cards into Zorro space for AmigaDOS drivers to access - small IDE drives, several flavors of Ethernet, serial and printer ports, primarily, but it's possible to talk to a variety of non-DMA cards with it. Someone once ran an FM tuner card via a DOS emulator... the emulator mapped 80x86 I/O instructions into 680x0 memory access instructions at the right place in memory for the DOS programs to hit the hardware. There's also good xBSD support for the GG2 Bus+. It's not firmware that he lacks - it's logic equations/a fuse map for the four GALs, three 16V8s and one 22V10. They provide some of the logic for translating ISA bus signals to/from Zorro II bus signals, and, equally importantly, the logic for emulating a nybble-wide ROM so that AUTOCONFIG can detect and classify the card. No AUTOCONFIG means that the card won't appear in 16-bit Zorro space. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 12-Jun-2004 08:20 Z South Pole Station PSC 468 Box 400 Temp -69.7 F (-56.5 C) Windchill -111.6 F (-79.8 C) APO AP 96598 Wind 15.5 kts Grid 044 Barometer 680.4 mb (10611. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html
