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

[Abinsium]

Finns det någon bild på eller broschyr om MYAB CP/M för ABC 80 
respektive ABC 800? Jag googlade men kunde inte hitta något annat än 
diskavbilderna.

Jag testade för några år sedan COMAL för CP/M på en billig dator 
(DuinoMite-Mini). Tyvärr var VT52-emuleringen dålig så man kunde inte se 
markören i COMAL. Det var också problem med att antalet rader var fler 
än COMAL förväntade sig, vilket ledde till krascher för vissa kommandon 
som skrev på de extra raderna.

Själva videon är dålig, men det finns nyttig information i beskrivningen:
"It's possible to run the common, industrial, seventies OS CP/M-80 on 
the DuinoMite-Mini (the world's cheapest computer, cheaper than 
Raspberry Pi Model A). In this video I boot CP/M by pressing the 
reset-button and starting the development environment for the 
programming language Comal-80 (which is like another OS and similar to 
e.g. GW-BASIC but ahead of its time). I write a small program which 
prints "duinomite-mini" repeatedly on the screen and stop it with the 
reset-button. I then load and run a program that prints the first 1000 
prime numbers. At the end I print the manual for COMAL to the screen 
from CP/M and shuts down.

I have not installed COMAL using the installation program but when I 
tried this on another disk image the keyboard worked even worse. Now, 
one doesn't see the cursor and can use only part of the screen. This 
scrolling problem is due to that the screen in this CP/M has too many 
rows but it can be solved by poking an adress in COMAL, but then it 
crashes during listing.

In order to run CP/M and ComAL on DuinoMite-Mini you need to flash a ROM 
from 
http://www.df.lth.se.orbin.se/~mikaelb/duinomite/z80sim-ksd-olimex.zip ( 
source-code: https://github.com/TheCodeman/z80pack-1.17-ksd-pic32 ) and 
get the COMAL disk from 
http://www.autometer.de/unix4fun/z80pack/index.html and then change the 
name of the disk to drivea.cpm and place it in the root of the 
microSD-card. You can discuss CP/M-80 for DuinoMite here: 
https://www.olimex.com/forum/index.php?topic=822.0 . One can create new 
disks using e.g. the tools of the Linux-version and also import and 
export files to and from the disk-images, but this, however, requires 
some CP/M knowledge. I did export all Comal-programs on the disk and put 
them here: http://www.df.lth.se.orbin.se/~mikaelb/basic/comal/cpm/.

I never used CP/M until now. My 2nd computer, Amstrad PC1512 (w/ 8086 & 
later V30), could run CP/M-86 Plus but I used MS-DOS with GNUish tools 
and early versions of Windows. I did test CP/M-80 on the Commodore 128 
(C128) in 1985. In MS-DOS you could have commandline-editing, history 
and filename completion, but CP/M seems to lack some of these features. 
But CP/M runs well with a tenth of RAM."
