[abc80] Copying ABC-80 data tapes

[Anders Sandahl]

Lustigt,

Jag hade precis samma tanke! Så jag digitaliserade ett par gamla
ABC-klubben kassetter för ett tag sedan. Jag lade precis upp filerna i
arkivet: https://www.abc80.net/archive/luxor/sw/tape_images/ABC80/

I Mikrodatorns ABC står det lite om kassettformatet, var finns det mer info?
