It's at $9000 (thus the UD3) and works with the BASIC 4 kernel. Various versions exist for other memory spaces (so you can put it in a different ROM socket if you have other firmware that isn't so flexible, like some of the commercial entities were). > UD4 - (handwritten label) > B-AID > @A 70 (or perhaps 40) BASIC-AID. Somewhere, I have the printed docs to this, but expect that there is an electronic version floating around. It was a common set of extensions to BASIC like print spooling, auto-renumbering, appending, etc. My primary computer from 1979 through 1983 was a 40-column, BASIC 3 PET with a single tape drive. I had BASIC-AID, PAICS Toolkit, ROM-RABBIT (a tape accelerator) and SuperMon in my ROM sockets. I used them daily. It was a fact of life that having 12K of user-defined ROM code made the difference on a diskless machine. It saved endless loading of the same utilities every time I locked up the machine (which was often because I was writing Machine Language). -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: firstname.lastname@example.org The original webpage address is still going away.
