A friend recently gave me some manuals for scanning.
One of them was the german manual for 'superkram'.
This reminded me that I had 'superkram' on one of my old disks, but
never tried what it was.
Google found an ad for 'superkram' in the april 1981 issue of compute!.
According to this ad, 'superkram' is the successor of 'kram 2.0'

I put the puzzle together, the package contains:
- scanned superkram manual (German!)
- .d64 image with superkram program files and EPROM file
  (these where part of a disk which contained a unsorted software
collection, so I am not sure if this is complete)
- the superkram ad from compute!
The package ist at:

I haven't tested it yet, so if anyone tries it, please let us know, if
the package works.

> I couldn't test these in emulator as I have no idea how the KRAM is supposed to work (even on the real hardware). I have a d80 of the chip-protected Visicalc disk, but I couldn't figure out how to attach the BIN file to VICE emulator (tried as ROM A/B, but then the emulator wouldn't reset: only black screen).
> Other than these two, I don't think I have any un-available/rare ROMs (thought these two were as I was asked to dump them) in my machines but I'll keep looking. Also I am interested to try upgrading my 1526 printer's ROM to the later version.
