I have a line on a Xeltek Unipro for really cheap (<$20). It is as far as I can tell the very first model Xeltek made. Software (not updated) is still available on their website. It comes with an ISA card and needs a 386~ish/DOS machine to run, like the one sitting right here under my desk.
Is this programmer still useful for anything? I'm mainly interested in making my own cartridges for e.g. TI99, MSX, Atari. But I also occasionally make stuff (synthesizers, music gear, who knows what) from kits and being able to write more modern chips for things like that would be useful too.
Can an EPROM burner write EEPROMs or do I need completely different hardware?
