Very nice work. This is great to see. Thank you!

No mouse? Send me your shipping address in private mail.

Hardware to run it?! Jeeze. There are four or five such systems
within half an hour's drive of here (at different places) and probably
twenty machines here at my place. =)

I haven't seen them online. I *might* have them on paper. I will
have to dig.

I think it should, but I'm pretty sure the only framebuffer I've ever
used with a KA650 is a VCB02 so I can't say for certain. What release
of firmware do you have on your KA650, is it possibly an older one?
I know lots of stuff was added to the KA650s ROMs after they were
introduced, and I know the very early KA650 ROMs were little more than
the KA630 code re-jiggered to run on a KA650. Dusty memories suggest
the KA650 was rushed to market before it was quite done; maybe the
earlier ROM code didn't do VCB01s.
