Eprom programmer question

[channelmanic]

If unsure, the safest way to do it is to start with the lowest and go up until the chip programs successfully.

If you program at too high of voltage then the chip could easily fry.

I did a search on ebay for a programmer that would do my Galaga rom chips and I found this. Will this work with my 2532a chips? I think it will but I just want to B shure.

After doing some more reading I have found some info on the 2532a chips and how to program them.

This link should help with the TI2532a chip programming problems.

Don't waste your time with that Willem crap. Just buy a real programmer. You should be able to find a decent used rig for under $150.

If you do a search here you'll find lots of suggestions (including some in this thread). Go with Needhams, Transtronics, Batronix, Xeltek, etc. Avoid Willem and all the Chinese Willem-clones in fancy packaging. They may be fine for most modern parts, but they're just going to be a headache when working with vintage stuff.
