Noticed that + right away. Delicious!
You wouldn't happen to have a prototype hexbus video adapter would you?
And it is at this point I start whimpering.
I had one once upon a time. Picked it up while I was living in Lubbock from a TI employee who worked on the 40 project. He didn't want it so he sold it to me along with a VERY early hexbus floppy drive (lots of wire wrap and in a Commodore style case).
Sadly, I got short on money and sold it all. I've been kicking myself ever since. Especially given the guy who bought it all didn't even finish paying me for it all and disappeared!
