Hi Tarloth
Yes, your question is a very good one because I can't buy one of the expensive programmers with a USB port for my little money wallet ☹️
I have an old EPROM programmer with an ISA connector for PC because they would not make more PCs with ISA connectors that have been obsolete. Well, I have a modern PC with USB ports and a USB to RS232 interface board.
A while ago, I found and downloaded the same BYTE article (PDF).
We are right; I know this is this old article, y many years ago I finished building a complete module with an 8052-AH BASIC microcontroller and its other components.
I am going to build a new I/O expansion for EPROM programmer.
This programmer cannot run without this program, how does a BASIC program to record EPROM memories?
I doubt that Steve Ciarcia would recognize this article and I do not know his email.
How am I going to contact oPossum? Greetings
