I do not know. I do, however, have an abundance of 6821 chips.

What model? They had at least 4 or 5.

Perhaps not a true acid test, but one that reassures me as to its veracity.
I loaded FOCAL-8 tonight from tape via the '33s reader, then typed in one
of the example programs from the programming in Focal pamphlet that found
the intersection of two functions and then "plotted" them using ASCII
graphics. It all worked as expected so I'm officially declaring this setup
revived. I also found a kind soul on the greenkeys list who will re-ink
ASR-33 ribbons so I will have something of a supply of those. All in all I
am quite pleased and it should make for a _much_ better VCF display running
Focal than it did last year just running the memory test!

Paul was one of the founders of the First Amiga User Group in the
mid-80s in San Jose. He soon became part of NewTek, makers of the
prescient DigiView video digitizer for the Amiga, and the video
manipulation device the Video Toaster.
Paul left NewTek with several other employees to form Play several
years ago, who made the Snappy video digitizer for PCs, and the
Trinity video effects device.

For Q-bus:
M7196 TSV05 Q TSV05 controller for Q/Q22 bus
For Unibus:
M7455 TSU05 U TSU05 controller
Since the TS05 interface is just a minor variation on Pertec Formatted,
*most* generic Pertec formatted formatters (i.e. Dilog DQ132, Emulex
QT13, etc.) will work.

I will have to look. I bought a former Commodore dealer when they went
bankrupt in 1992. I do have a tacklebox full of PET parts. I have no
idea what a 6520 is worth these days. They used to sell for between $5
and $10 when I had to replace one in the old days.

This is not really on topic, since I failed to find any classic computers,
but...
I just got pointed towards qxl.com, "Europe's biggest on-line auction".
It was (a) very short of stuff for sale; (b) expensive; (c) devoid of anything I
might have considered buying.
Has anyone on this list _ever_ bought _anything_ useful and/or at a sensible
price from QXL?
Or had I better just look at the US on-line auctions and pay the transatlantic
shipping?
Philip.
