Woo-hoo, thanks for the work on the 7220, crazyc (& Kale? He was posting about it in the pc-98xx thread). It looks like the drawing areas are converging ... and is that Zoom in the characters? cool

With Sandro's recent addition of CopyQM files and a softlist, it's waiting to have software thrown at it smile

I think I've found the source to the positioning problems. If the GD bit is set in the FIGS command then pitch is effectively halved but only when figure and char drawing and in mixed mode. Still need to figure out exactly how it works though.

That thing is a great test case for the uPD7220

Speaking of which, with a solid uPD7220, could we emulate a Number Nine Revolution ISA card?

Another great test case for the uPD7220 is the Nokia MikroMikko 1 driver, but currently it won't boot from floppy for some reason.

Vas: if the video BIOS and drivers (if there are any, they're pre-Win 3.x) / software for those cards turn up, it should be possible.

Yeah, that Artist-1 board is definitely a 7220. No obvious (P)ROMs either.

I guess the next question is, does the #9 Revolution ISA have a video BIOS, or is it strictly a second-monitor-for-CAD type of thing? The latter we could probably emulate just with what the Internet Archive has.
