Re: [N8VEM-S100:2112] Interest in an S100 backplane order?
If you can't generate enough takers for a S-100 backplane order, I have something that might interest you. It is a 17-slot S-100 backplane PCB (unpopulated) with active termination. It measures about 16.5" x 10". Everything that would be needed for a nice backplane can be mounted on the board, including those gi-normous capacitors that were so common on S-100 power supplies. There is a place for a 6-pin (probably Molex?) connector for +8, +/-16 and ground. Also there is a circuit for a de-bounced (74LS00) reset switch. The active termination circuit would require an LM4250 (round can with 8 pins). I think they can still be purchased from places like Mouser for about $1. Looks to me as if all that would be needed (externally) would be a +8v and +/- 16v power supply. The PCB is 2.5 mm (very stout), and is marked: (C) 1980 Micromation FAB 681-002 rev. 4.0 assy 901-018.
I'm retired and will never be able to afford to buy even a few of the 100-pin connectors that would be required to get the thing going. Where are you located? If you are in the U.S., I'd sell it to you for $50, shipping included.
