First personal computer nostalgia

First ? Well this woul be a never finished 4 Bit CPU build up from real transistors in '76. Back than, at a training lesson, I did a discrete NAND gate at the size of a bottle cap which stated the thing. The task was to put 4 NANDs on a Eurocard board (4x6" ?) with a defined connector - and I did put 'em as compact as possible into the corners - as mirror images of each other. Doing this I realized that I may put a 4 bit adder on just one board, and it took of - just to be scraped somewhere halveways and replaced in '77 by a design around a Valvo/Signetics 2650 CPU with the terrible hughe MEM of 64 Bytes. All TTL, and horrible expensive - I had no idea, and the TTL list was my best friend :) Data input via switches and trigger button, output via 8 LEDs :) Next was a KIM in 1978 ( I couldn't aford the AIM :) and in 1979 an Apple ][ - I had to take a loan to buy it - just to be drafted half a year later. 1983 a PC-Clone joined my living room (almost as expensive as the real one) - no, not for programming - I still did all IBM Jobs with Turbo Pascal in CP/M on my Apple - transfered them to the PC and did a recompile, colour adjustment ad teyboard test. 1984/5 Finaly a PC replaced my Apple, but again not a IBM, not even a clone, but the Siemens PC-D (in my mind still the best ever x86 Computer). Oh yes, and another footnote in 1983 - the PET - the first computer I bought just to have it... basicly the start of my collection. :)) Gruss H. -- VCF Europa 2.0 am 28./29.
