Still Waiting ... In the Mean Time...

A project log for VDC-II

Commodore 8568-inspired (and mostly compatible) video core for driving VGA-type displays.

While I wait for the 74LVC8T245 chips to arrive, which seems like it'll be forever thanks to a certain virus, I've decided to try and use my spare TinyFPGA BX as a test harness for the VDC-II.

This means resurrecting the Kestrel-2, but in a reduced form, as the TinyFPGA just doesn't have the same resources that the Nexys-II's FPGA (Spartan 3E as I recall) has.  The first step towards targeting this chip, though, is rewriting the CPU into nMigen, a process which I've already begun and hope to finish soon.
