Need Some Info

I bought a whole heap of atari stuff which included these 2 boards. I'm assuming they are eeprom boards, 1 is 28 pin, the other 24 pin. The website on the pcb (vgwiz.com) has no mention of these on there. I'm assuming they are blank, any info would be great, cheers :-D

The current vgwiz.com website is unrelated to the old one which, up to about a decade ago, was selling Atari homebrews related hardware (cartridge cases, pcbs and flashcarts). When you find old references to websites it's always a good idea to check the wayback machine on the internet archive page, to see what was online at a given time.

The boards you have are eprom (not eeprom) boards with sockets. The one with the 24 pin eprom is for non bankswitched games (2k and 4k), the other one for 8k games using F8 bankswitch scheme. Since they put a sticker to cover the window of the eproms, I guess they are programmed. As SeberHusky said, just plug them into an Atari (with the eprom chip facing up) to check them.
