Marska with his very first computer
I bought my Osborne in 1981 at price ~17000 FIM.
The flat cable goes up to a eprommer (myself done of cource).
I made Z80-based assembler programming with Microsoft Macro Assembler M80.
It was the time when Microsoft begun to develope first version of the Ms-Dos operating system to 8086 computers.
Those were the days !
