PROM / EPROM Chip programming service. I can program the common models that
I have listed for sale or perform custom orders for many other chips based on
your needs. Send me a message with questions and requirements before
Chips can be programed with your data file or I can duplicate a chip if you
send me the original.
PROMs are new. 2708 EPROMs are previously used, erased, and verified good.
Used in vintage computers, (Apple I, Apple II, Apple III), Ham radio, arcade
games, and many other vintage equipment use cases.
The "82s" PROM model numbers above are Signetics and Philips models, but are
functionally the same and can be substituted in place of other PROMs from
Harris, Fujitsu, MMI, TI, etc. See the links below for a compatibility
