Altair replica 4 slot backplane motherboard S100 S-100 IMSAI 8080A Z80 Kit:
$119

This is a very close replica of the Altair 8800A 4 slot backplane.
It can be used to re-create an Altair 8800A system, to extend an original system or for general 8080A / Z80 S100 projects.An original backplane was professionally scanned and Gerber files created. The backplane was then fabricated using double thick PC board material (3.2mm).The original backplane was produced in both standard PC board material (1.6mm) and the thicker (3.2mm) style. The thicker boards are much sturdier. I do have a few of the thinner boards fabricated and can provide those as well if preferred, just let me know in the comments. I have sourced the original Sullins Connectors.These were expensive and make up a large part of the cost of the kit.
The kit includes:1 reproduction backplane in 3.2mm thickness (1.6mm upon request, same price)4 Sullins S100 edge connectors8 Edge supports (3D printed from ABS plastic). (Screws for the Edge supports are not included at this time)The last two pictures are of an assembled kit, and also an original Altair for comparison.
periodically adds "make an offer" option to listings automatically. The cost of scanning the boards, sourcing the original connectors and printing the edge supports is significant. Sorry but I can't reduce the cost further and will decline offers.
Because of the time needed to print the edge supports I will only list one at a time. I do plan to re-list periodically as they become available.Postage is at my actual cost.Please see my other sale listings for Altair and Imsai 8080A CPU Card.
Documentation is available on line and by Email. I will forward links with the board, but unfortunately can't post them here.
I am happy to accept returns if you are not pleased for any reason as long as the board is not assembled. You will need to pay return shipping only.
