Re: A Simple Programmer for TESLA "MH74S-" bipolar PROMs
We have a couple of new points since my last visit. (These threads go fractal so quickly.)
The one I'm looking at now is possible variations in SCMPKB.
Curiousmarc gives us a crisp reproduction of the NS-supplied teletype listing from the 1976 SCMPKB assembler run. And he's used it to recreate a PROM.
The other sample is from 8bity.cz. (I once sold Martin an '8060N on ebay.) I've trawled through that site and I can only find the SCMPKB listing that's in a full scan of MK14 Manual Edition 1.
This has been retyped and has several 'points of confusion' but the code is the same.
Can you actually display/list the points where your 'modern' EPROM contents diverge?
It is possible that NS used other code versions in their own units. Observe the display in attached.
