New in my collection: a TIM IC! 6530-004 2577
With the intriquing name SUPERKIM an engineer called Paul Lamar designed a SBC around the 6502.
The main design decisions were to be a superset of the KIM-1, requiring no alteration of KIM-1 programs or user interface (the keyboard/display!) but with much more extendable resources. And the result is just right, it Is a KIM-1 with many improvements!
Read all I know here!
Have a look here for full information, including new PCB’s and software on the famous Tangerine Microtan 65 system.
The website https://sites.google.com/site/gogleoops/home is to look at designs of older microcomputers and provide information to people to be able to build some of these for their own use. It is aimed at micro enthusiast with reasonable knowledge of electronics and digital/microprocessor theory.
There are still many older “original”microcomputer boards for sale (on Ebay etc) .. but tend to be rather expensive and in most cases those boards are either not functioning (due to age) ..or rather limited in their operation or not being able actually connect them to anything useful (like current PC’s or terminals).
So in my quest to play around with some of different varieties of microcomputers (like SC/MP, 6800’s, 6502’s,TMS9900’s, 68000 etc) I am sharing some of the design (like pcb’s).. so people can build their own. I do provide some components .. but this is not a commercial venture, so you might have to source other bits from different sources to complete any of the designs. Some are prototype and some are fully built sbc (single board computers).
Now with 6530 and 6500/1.
I discovered more unique 65xx IC’s in my stash of boards.
I have added two pages with photos and manuals of two 6502 SBC manufacturers:
