Microsystems International ICs
MIL made several versions of the 1701, 1702 & 1702A EPROM. Below are pictures of ICs that I have in my possession or have seen online elsewhere.
MIL also made several type of RAM.
No data or pin-outs could be found on the MIL MF2113-2P. All that could be found was from an ad, which states that the MF2113 are 256 x 4 bit static RAM, tailor made by MIL for system versatility. It has a 22 lead package with separate I/O. One might think these might be clones of Intel’s 22-pin 2101 chip, however, if you reverse engineer the pin-outs from the board layout, it becomes clear, that the chip isn’t pin compatible with the Intel chip. A casual glance at the board will show that pins 8, 9 and 10 are tied to ground. On Intel’s 2101 chip, pins 9 and 10 are data pins DI1 and DO1 respectively. It would make no sense to ground these pins out. The pin-outs of the MF2113 were determined by reverse engineering the circuit. The only two pins that could not be determined with certainty were the CE2 and the OD.
There appear to be two case styles of MF8008R CPU chips out there.
MIL made very few 8080 chips. It is unknown at this time if any were sold commercially. Most that exist appear to be unlabeled, however at least one engineering sample labeled MF8080RX is known to exist.
MIL produced a chip known as the MD6150, which was the equivalent of the Intel or the more commonly known 74LS138. There are at least two variations of this chip, one in a ceramic case, and the other in a plastic casing.
