I just got the preliminary specifications for SD Systems new 68000 board. It boasts: o 8 MHz 68000 o 68451 MMU (Memory managment unit) o Completely IEEE 696 compatible o Two RS232 serial ports (8530 SCC, Async, Bisync and SDLC modes, independent baud rate generators) o 20-bis parallel IO (8536 CIO) o 3 16-bit counter/timers o 32 Kbytes ROM (two 2732's, 2764's or 27128's) o Some of the bits on the parallel IO chip can be used as a vectoed interrupt controller. This sounds like a real slick and well thought out board. They're beta testing it right now, but I don't know when it will become publically available or how much it will cost. Speaking of SD Systems, is anybody using their VFW-III floppy/winchester controller board? I've been eyeing it, and I'd like to hear from somebody actully using it. cheers, -m- (mkb@cmu-cs-c)
