About small SBC systems
An article from Micro February 1979 shows how to enhance the TIM monitor.
Have a look here for full information, including new PCB’s and software on the famous Tangerine Microtan 65 system.
Two IC’s 65C102 added to the IC collection.
Rockwell, 8639 and 9009 date codes.
I got hold of a rare 65c802 and some NOS 6504 and 6507’s.
In the 65XX IC gallery now photos!
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).

I started adding datasheets to a new page called Datasheets!
Now with 6530 and 6500/1.
I discovered more unique 65xx IC’s in my stash of boards.
So more 6502, 6521, 6545,6522 and 6522 shown here!
I have added two pages with photos and manuals of two 6502 SBC manufacturers:
EMMA and EMMA II by LJ Technical Systems. Educational SBC’s KIM-1 like, part of a whole eco system
John Bell Engineering, 82-300 SBC 6502, 6532 2716, 80-153 SBC 6522, 6502
A new KIM CLone kit is coming!
Bob Applegate is filling in the gap left by Vince Briel, with his own design.
