Dear all,

>From time to time I collect 8296D computers at eBay, mostly to strip
internal drives from them for my 700's :-)

Today I repaired one 700, so I went to a 8296D which has been sitting
idle for many months to strip the drive. Upon opening it, I saw an
additional board attached to the motherboard, piggybacked on the CRTC
and character ROM.

>From a short mention on Andre Fachat's website I reckon it must be the
8296GD cariant, with a hi-res graphics adapter. The "adapter" is
actually just a small board with a 6545, EPROM, 8 TTL chips and 4

There are these ROMs in this machine:

324243-04 8296D DIN
324993-02 HiRes BASIC
324992-02 HiRes Emulator
824242-01 DIN8296/8296D (in the video board)

The computer powers up, emitting strange beeps from the buzzer, and
displays standard BASIC 4.0 welcome message. The keyboard has some keys
missing unfortunately.

I haven't been able to find any documentation on this graphics card and
I don't know how to utilize it from the BASIC. I will dump the ROMs and
try to look at them, but maybe someone has documentation scanned which I
could look at?
