x8 eeprom source
« on: February 06, 2019, 01:27:19 am »
anyone have a source of cheap but known real 28C128 or 28C256 parallel EEPROM in PDIP-28 package?

The ones on eBay look not quite right but what do I know.

This is for reviving vintage computers... pretty soon if I buy from Digikey or Mouser I'll end up paying more than the computer itself cost...

Yeah but by the time I buy 10 pieces and add shipping I'm looking at a new computer...

I'm just wondering if there's a known-good vendor of these 1.50$ EEPROMs. Googling each ebay vendor doesn't bring good news.

Don't know where in Canada you are. If you are in Ontario check out Sayal.

Is this for EPROM replacement, or are there vintage computers that had these designed in?
