Reading a N82S123AN PROM, what do I use?

[GearTechWolf]

I have a BPMicro EP1132 but it doesn't seem to support PROMs? At least the BPWSoft-03 program doesn't bring anything up in the device list.

Does the video at [here] help ?

Given that it's a 32x8 bit EPROM, even the lowest of arduinos could do the job. All levels are TTL.

Yes and no, but thank you regardless! Now I know their pinout can be arranged to be read as a 27CXXX chip, but I'll have to figure out the specifics myself.

That's awesome, thank you!

Or, to put it another way (as I happen to have been asked this exact question before)....

In the EPROM programmer's software limit the size / length of the read to 32 bytes (Begin: 0000 End: 001F) otherwise it will read the 32 bytes many times over and make it look as though there is more code in the PROM than there is.

Excellent, thank you!
