This backplane is designed to fit in a half width 19" Eurocard rack.
It takes a mix of 64-way Eurocard sockets (x6) and 72-way edge connector sockets (x4) as RM 65 boards where available in both formats.
I have a range of replica or compatible PCBs available, mainly for the early Acorn System Computers range but also for the later Acorn Atom, BBC and Master computers as well as many Econet components. Also some early SC/MP based items e.g. the MK14 Computer and Rockwell AIM-65 & RM 65 items.
Not all of these boards may be in stock, if you wish to buy an out of stock board drop me an email and I will reorder.
Further details can be found on my website, including all the Schematics and BOMs (Bill Of Materials).though you'll have to search for it because I can't put a link here - try 'acorn system computers website'.
I will combine postage on multiple items, please ask for a total before paying as I cannot combine postage after you have paid !
