This reminds me of my first experiments with a uP board, one that, I am sure, will awake many memories in our UK friends, the Nascom 1... I bought it in London, in kit form, during a trip there. It was Z80-based, 1 kB of RAM, and I hand-assembled the programs for it, computing all the branch offsets by hand... imagine the joy when you had to insert new instructions in the middle of the program... but I managed to stuff an RTTY decoder in that 1 kB... then I bought the 32 kB expansion, a luxury indeed, the assembler program, and the fun ended...:-) I still have it, in my nostalgia department... 73 Alberto I2PHD
