One of the reasons I wanted to build a Retro Chip Tester (RCT) was because there are several adapters available that let you extend the capability of it.

The one I had an immediate use for was the 2708 programming adapter.

I ordered some PCBs for this, put it together and it has now been tested and programs these old chips without too much fuss.

I also added a Wi-Fi adapter to the SD Card, so instead of unplugging the card every time I needed to read / write an eprom, I can simply open a file share from my desktop and access it that way.
