Re: Zeta Working Correctly with 720kb

[Sergey <skis...@gmail.com>]

The Parallel Port Propeller board is coming soon (hopefully...
depending on the availability of my time). That board will provide
keyboard, VGA, and SD card capabilities for Zeta (or other SBCs with
8255 PPI), and additional RS232 port (a simple three wire one - TX/RX/
ground).

Thanks,
Sergey

Turned out the FDC9266 was porked, but even with the replacement, the Jackie Chan ed didn't work in this config.
