The early UK computer projects I know about are : the 'PE Champ' (that's tue UK magazine 'Practical Electronics') from 1977 (a 4040-based computer + 1702 programmer + UV eraser) ; the PE Digi-Cal from 1972 (a 4-function dsektop calculator built in TTL + a diode-matrix ROM. I don't recall any general-purpose computer built from TTL in a UK magazine. [ snip ] -tony I believe that Elektor was publishing in the UK in 1974, but I don't have my copies at hand to pick the exact date. I know the first and second binders were full by the end of 1976 (I used to buy the publisher's binders, an icky green, tacky board binder). And I read all of them but do not remember any computer projects. And I would have been extremely interested because I was building an 8 bit TTL machine at the time. However, there was the ACS (Amateur Computer Society), an early UK computer group that designed and built a 16 bit TTL computer. It was well documented in their Newsletter in the mid-70's. All my copies were stolen, and I've looked for 20 years to find copies. Any chance of the UK CC'ers having copies of these newsletters? Billy
