Here are some of my Intel C1701, MIL MF1701R and MIL 1301s. Not sure why one Microsystems International Limited (MIL) 1310 had a solid cover and the other one a clear. Must have been a mistake or was it common? with later EPROMs?

These x3xx series are ROM instead. Chance that this 1301 may be masked ROM Confused

The die is the same, so perfectly fine, but kinda funny (the window should have a sticker)
