Hi,

Trying to be more precise, almost in pedantic mode :-)

The Cheese Wedge version was called Second Processor. Such model I bought
new, and indeed I can't remember of any discs accompaning it.
(The processor is a Rockwell version in 3 MHz with additional opcodes)

With the Master Series the concept was renamed to Co-Processor. My first
Master bought, was second hand and included a 6502 CoPro. AFAIK this was
always with a 4MHz 65C102 processor.

With the latter, a lot of extra things came with it, and one of them is a
support disc. I don't know if that was standard from the beginning when the
65C102 CoPro was released, or later, or was always an option to be ordered
seperately. Anyway, the 5.25" disc is labeled with the Master Series logo in
the same way as the Welcome & Utilities Disc.

The lable of the latter has a vertical line 5.1x cm (just slightly more than
2.0inch) from the right, and with a text concerning the 40/80 tracks format.
For the CoPro support disc this is about 1.5" (3.7 cm). The main text is:

  65C102
  CO-PROCESSOR
  SUPPORT DISC

and the disc contains HI-versions of BASIC and EDIT, and a printer buffer
program for in the I/O processor (the 'Host'). The disc shows itself as:

FWIW,
