One of my Fall projects is to figure out why my Data I/O 29A isn't working. It's been sitting for years and when I got it out last year, it didn't pass self-test. I need to spend some time looking over the posts in that group to see if my symptoms are common. That said, unless you need to program stuff other than 2716-27512 and up in that line, an old Data I/O is probably not what you need. If you need to program chips made before 1985, then it might be a good choice. -ethan
