For both the friendly list participants and the two

who kindly took the time to email me to call me a liar (no SuperPETs
for you!), I have taken some photographs. You can find them at the

I'll direct your attention to the fourth picture. Two of the SuperPETs
contain those "Super OS/9 M.M.U." boards produced by the Toronto PET
Users Group (TPUG) [1] back in 1985 and if memory serves, they allow
for bitmapped graphics on the SuperPET. They are somewhat rare and I'm
not even sure if we (TPUG) have one in our inventory. I'm going to
make some inquiries as well as have a closer look at the board and
I'll post about it later. I may end up attempting to clone the board
and if I'm able to, I'll make them available to TPUG members at cost
(everyone is welcome to join, hint hint.)
I'm not one of the Doubting Thomases per se, but that board sounds more
like a OS/9 memory management unit. It looks like it plugs into the
6809 socket and allows some funkiness with the memory map.
The board looks trivial to clone. I'd run one out on Eagle if a board
makes it my way to run the DMM over.
