Altair MITS S100 Backplane 8080A S-100 Replica IMSAI CP/M
This boardis a very close copy of the vintage board and has been produced by taking an unassembled Altair MITS Backplane and having it professionally scanned and converted to gerber files. This reproduction of the original 4 slot backplane is useful for fixing an original Altair, or if you insist on being true to the original early version. If your planning a larger S100 system or don't care to be authentic I'd suggest using a larger backplane as stringing two or more together is a royal pain!The reproduction Altair 4 slot backplane was produced using double thick PC board material (3.2mm). The original backplanes were produced in both standard PC board material (1.6mm) and the thicker (3.2mm) style. The thicker boards are much sturdier. The cost of fabrication is significantly higher for the thicker board, but I think it makes for a much nicer result.The Edge Supports can be 3D printed using a .STL file I will provide a link to. This sale does NOT include the supports for folks who would prefer to print locally. When I have time to print supports I will post a separate listing which does include the supports.This sale is for a bare PC Board ONLY.
The S100 connectors are Sullins EBA50DRTH and are available thru Digikey and other vendors. They use a narrow footprint which is different than many other S100 connectors. They are NOT included in the sale. Screws to mount the Edge connectors are also not included.Documentation including assembly manual and the .STL file for the edge supports are on the web ( rules foroffer me posting a link, but it will be included with the board).
A picture of a completed backplane, with correct S100 connectors and edge supports is included so that you have an idea of what a completed board looks like. Again - this sale is for a bare PC Board only. Please see my other listings for a replica of the IMSAI CPU board and IMSAI MPU-A CPU Board.
I am happy to accept returns if you are not pleased for any reason as long as the board is unassembled. You will need to pay return shipping only.
Postage is at my actual cost. If you order more than one board there is no additional shipping cost in the USA.
There may be a few times where it takes me an additional day or so to ship because of my travel.
