I've come to realize that having an EPROM programmer that can handle the older 8-bit EPROMs is essential for the retrocomputing hobby. I have a version of the inexpensive and popular TL886 programmer, but it cannot handle most vintage EPROMs. I ran into that problem when trying to replace the Cortex EPROMs.
Currently I have a specific need to program a 2532 and a 2716 EPROM to upgrade the ROMs on my Heathkit H19 terminal so it can do 8-bit serial communication instead of its fixed 7-bit, thus making it much more useful. I usually use it to communicate with my Heathkit Hero Jr robot, but otherwise it sits idle and forlorn. I recently fixed my P112 CP/M SBC and I would love to use the H19 to connect to it
Any suggestions on an EPROM programmer that can handle the job?
