SNIP....
Other than the Timex/Sinclairs, what's the cheapest
machine which was
available in 1982 that I could have used to learn BASIC and assembler and
machine code -- at home?
I bought my first computer (a TI 99/4A) in 1981.
I am almost certain that the price for the console package at that time was $99.
The Ed/asm was an available option for an extra charge.
