These were pulled from КР573РФ5 EPROMs (KR375RF5 in English), which are clones of 2716-series EPROMs.
If someone needed to make EPROMs with these dumps, they can use minipro with the M2716@DIP24 device and use basically any 2716 EPROM.
They could even write the dumps to КР573РФ5 EPROMs with minipro using M2716@DIP24 as the device, if they wanted. This is how I pulled the dumps :)
