    I boughjt Rasso Von Schlichtegroll Macroassembler. I have casettes.

    However, there is no cassette device working properly. Downloading requires a good quality.
    I would appreciate if somebody has that software to send me.
    I have CE155 for interface with a computer.

      I had the macro assembler as well, but lost it (i was a schoolboy at that time). I have a cassette device connected to a soundcard, so I can digitize the old tapes. Let me know.

          That’s surprising how old tapes can deliver proper content after 30 years.
          The firsts checks to do are on tape reader/recorder :
          – Cleaning the head
          – Verifying the belt. Most don’t survive. It’s a very common problem on the CE-1600F floppy reader for PC-1600.
