Here you can see my first real hacked up coco. This
one came before CoCoZilla. Click each picture for a really BIG shot. It
ran OS9 level 2.
Front
view, showing the IBM slant front case without the top. CGA monitor in
back. Two Rodime MFM 10MB drives on top. Also showing are two 360K drives
in the case while a 3.5" 720K drive is sitting on the top of those mounted
floppies. Yes, this does drive that CGA monitor. And, yes I used it just
like this picture shows.
Showing
the MFM interface setup and the four slot MPI clone (cable) attached to
the inside of the front of the case. The empty slot was for the A/D board,
somehow got removed for this picture.
On
the left is the CGA adapter board. This CC-2 motherboard was made at Tektronix,
they just didn't know it. It was made for use in a research lab as a "controller".
Only two were made, I have one, still runs, has a ceramic packaged MC68B09EP
installed. Bottom-Right, PIA printer port plug-in card. Also, not shown
was a 12-bit A/D board tied directly to the analog DAC, so that a scaleable
8/10/12-bit joystick interface could be used, yes, I used it. Behind the
IBM MFM card is a quad 6551A card. Behind that is the MPI clone buffer
board.
