Kim-1 Enhancement PROM 1977

[GeoNomad]

I came across this source listing for the Kim-1 Enhancement PROM dated 1977.

15 pages plus symbol tables etc.

It looks like it is by Rene Vega of Detroit September 1976

It contains Jim Butterfield's Supertape and some other utilities and code.

I can take images of it all and save it, but don't want to spend the time if someone has already done that, but I don't find it in a quick search.

So, if someone wants it, please ask.

Otherwise, it is going into a box of documents destined for the Computer History Museum.

Look at it here: http://benlo.com/ComputerHistory/EnhancementPROM.html

Great stuff! Thanks for posting. I copied the images and I'm trying to OCR them to produce a source file...so far recognition efficiency isn't particularly good.

Attached ASM was basically typed manually. Recompiles with TASM just fine. Enjoy.

Good job, Rich!

A few OCR errors left over in some of the comments:

Thanks! OCR didn't work, so I typed the entire thing in from scratch. I made those corrections in my original. Much appreciated.
