[abc80] Fanns COMAL till ABC 80 eller ABC 800?

[Anders Sandahl]

Hej,

Jag hittade en kopia på en kopia av bruksanvisningen på CP/M för ABC800 så
den stoppade jag i skannern:
http://www.pdp-9.net/archive/luxor/sw/CPM/MYAB-Bruksanvisning-for-cpm-pa-ABC800.pdf

Det finns också omnämnt i prislistan från MYAB:
