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.
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.Does the video at [here] help ?

PINOUT
X is Not Used/Terminated.
Outside row of pins is for 82S123, 82S129,82S131 IC's connected to the 27512 Adapter.
Excellent, 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.
