Title: Looking for an eprom programmer
Post by: LektroiD on September 13, 2016, 03:18:12 pm
I'm looking for a cheap EPROM programmer, it will possibly only have one use, ever. So not looking for anything expensive or with all the added bells and whistles...

Basically all I want to do is flash the firmware on this chip, and I'm done...

Recommendations?

Took me a while to get that in English... Seems it's £50 with postage, a bit more than what I had in mind to spend, the unit I'm flashing is only worth £50 anyway...

Is there any reason to spend that much, or will something like this work with that chip?

And re-sell it when you are done.

If you have onl;y one eprom to write, is easy to find somebody that have one and can wrote to you, otherwise is quite cheap

Do you have an Arduino and some 74x chips handy? Google image search for  "Arduino EEPROM programmer" turns up several prospective designs.

If you were willing to spend some money on a tool, the MiniPro TL866 is an absolute bargain. It can read, write, and/or test many devices including (EE)RPOMs, RAMs, NVRAMs, microcontrollers, PALs, logic chips. It is one of those "I'll never again go without one" kind of tools.

MiniPro TL866

PALs

I was wondering, can it do PALs / GALs reliably?
That always seems to be the failing point for the Chinese programmers
