I have most of the hardware for a 68000 based S-100 bus system, which I would like to sell. It was bought for a project several years ago, which never got off the ground. None of the hardware has been used, and I'm fairly sure it all works, but I can not offer any guarantees. This would be a good system for a micro hacker to play with, or someone who wants to learn about microcomputers from the ground up. The S-100 bus isn't as popular these days, but there's a lot of stuff out there for it. The system consists of: CompuPro CPU-68K: 16-bit IEEE 696/S-100 microprocessor board, with 8MHz 68000, provisions for 68451 MMU (not included), two sockets for EPROMs (2716, 2732 or 2764). Power-on reset, auto-vector interrupts, complete bus interface. Note: no ROMs are included - you will have to buy boot or monitor ROMs, or roll your own. CompuPro sells a set that works with their disk/IO card, which boots CPM/68K (which they also sell). Sierra Data Systems ZSIO: 4 port RS-232 serial I/O and real time clock board. Uses Zilog SIO/2 and CTC support chips. Can be interrupt driven. Lexicomp Data Systems SR-64K: 64K byte RAM board, operates in 16-bit mode. Uses 100-ns 2016 CMOS static RAMs. Small by today's standards, but it's a start... Integrand 800 series mainframe: 15-slot S-100 backplane and cage, 8VDC@15A, +/-16VDC@3A, power and reset switch on front, fan, 2 switched AC outlets, cut-outs on back panel for 8 DB25 connectors, 2 Centronics style connectors, and 2 BNCs. Top comes off for complete access. Off-white with black front panel. This is a nice looking unit. Compupro no. 106 active terminator for S-100 bus. Vector S-100 extender board. 3 S-100 prototyping cards and a Vector 11-slot S-100 backplane. I have all of the manuals, and the original sales receipts. I was thinking that $500 (plus any shipping) would be a good price for the whole deal. I'd prefer to sell it all as a package, but if you just want a piece, make an offer.
