Since I'm in S-100 mode, I decided to check out two problematic S-100 RAM boards. One of them is a SRAM board populated with many 21L02s...an 8K board by the number of SRAMs. The only markings on it are battery connection, MEM PROT, an area labeled with 0-5, and LOGOS-I, which I assume to be the manufacturer or the system the board was used in.
Anyone ever heard of these and/or have a schematic? There's another 21L02 in a random 16-pin socket on the board...pretty sure that's not supposed to be there!
