Domestic Source for EPROMs

Not all foreign EEPROMs are bad... I got some nice Winbond 27C040's (the flash kind) from China and they work pretty well.

 

Not sure if the same seller is still there, but here's my eBay search:

http://www.ebay.com/sch/i.html?_odkw=winbond+-programmer+w27&LH_BIN=1&_sop=15&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xwinbond+-programmer+w27e040&_nkw=winbond+-programmer+w27e040&_sacat=0

 

The nice part is that you can erase these in the programmer.

I ordered a lot of 5 AMD 27C040 chips from a supplier in Hong Kong and what I got were a bunch of unlabelled chips, none of which worked. The seller said that the chip logo must have "faded" during storage and sent me 5 more replacements that were equally as bad. All I can surmise is that they were Chinese counterfeits. Then, he had the unmitigated gall to ask me to change my negative feedback. Not bloody likely!
