These are early programming adapters for the Data I/O Model 19 and
earlier programmers. These were used before Data I/O developed the
UniPak module which did all PROMs and EPROMs (except the 1702 ERPOM)
There are two cards in the large Programming Pak, an analog card and a
digital control card. (I forget the correct names.) The digital card had a prom
based state machine to control the programing algorithm. The analog card
generated the waveforms. This pak could be used in early Data I/O
programmers that did not have a microprocessor.
The you wanted to program a different part you need to swap cards.
The smaller parts a pinout adapters.
The two white things in the lower part of the picture look like your feet.
