This is a EA/DSE Eprom Programmer that appears to dates back to 1994. These were sold as a kit, I don't know it's history as it was in a box of misc parts I acquired. Had a chance today to take a very quick look at it and it appears tidy and reasonably well put together, bearing in mind that 22 years ago it's likely that who ever put this together had very basic tools.
Software and schematics are still available from the original designer. It uses a parallel interface and the software is MS-DOS based which was common at the time. From the quick look I had there's nothing obviously wrong with it which isn't bad for a 22 year old low cost DSE kit.
