Hey Joe,
You know... the Vantis Mach4 (M4-128N/64) has 128 Macrocells with 64
IO/s. It's an 84 pin PLCC, and about $20 in singles. You don't get
more than 64 I/O's unless you go to the TQFP package. :-(
Now that I've got a more complex Synario project under my belt I'm
thinking I'm going to give the ISA Vector Video Card a whirl. (Need to
talk to Neil and get a commitment for driver support from RetroCade...
;-)
