Check out Vicmon here:

AFAIK the $6000/BLK3 version is what were sold commercially as a
cartridge (atleast by Handic/Datatronic in Sweden).

However an article in a magazine (maybe even Handic/Datatronics own
VIC-News/VIC-Nytt/VIC-Rapport magazine) had clear instructions on how
to use the relocate feature of vic-mon to relocate vic-mon itself.
Officially the instruction were for those who were developing software
for $6000/BLK3 but unofficially it was to make it possible to take
tape/disk copies of the monitor even without having ram cartridge at

I guess that the non-$6000/BLK3 versions were relocated by some user
before being uploaded to Zimmers/funet. (Especially the $4000/BLK2
version has a far newer timestamp than the other versions).

There is als some "Monitor-sys24576.prg" file there. I don't know
anything about it, maybe it's another copy of vic-mon.

My impression is that vic-mon were a Commodore product that
Handic/Datatronic just made their own copys of, but Handic/Datatronic
had their own in-house software developement so it might be something
they developed themself.

P.S. there seems to be some real assemblers also. Haven't tried any of
them either.
