It was a Telemax Colormaster VCB-8+ which I purchased for $139 in April 1985, plus some peripherals for a Sakata SC200.I found a copy of a letter where I returned it in May because it didn't perform as described... some paragraphs about poke 50944,4 and deferred mode and immediate mode ?????50944 is $C700, so it must be a slot 7 card (which sounds right for a ][+ video card).
I've managed to get it working! I was getting a blank raster when plugged into slot 7. Or so I thought. Turns out that the vertical size was way, way too large. When I cranked it back, lo and behold there was the applesoft basic prompt and //e signon.
Video was reversed, but after re-reading the schematic in the Sather IIe book it turns out I was grabbing VID\ and needed to get on the other side of the 74LS10. Bingo.
Looks great on a NEC Multisync 3d :-).My Wei-Ya RGB-->VGA converter (used with a Commodore 128) can't quite sync to it, although it tries hard. When I get a spare minute, I'm going to make up a cable to bring this into the Highway 100 converter's SCART input.
