In this part of the site you will find info on the computers I owned and worked with, as well as general info about computer systems. The picture below is my first computer, the ELF II (see also this link). It’s got a RCA 1802 processor, that was also used in space ships and satellites like the Voyager, Viking and Gallileo spaceships.


On this board, I learned to program machine-code and assembler. It had a whopping quarter K of memory (yes, a full 256 bytes!) in which I programmed my first model-train track. Ahhh, memories…
