Uh huh--no E/EP/ROM on the board at all--just the XC2064 and a bunch of
TTL.  It appears that the device driver loads the bitstream.  Of course, I
don't have and can't locate the device driver.  

I think it's time to pull out the soldering iron and get rid of the blasted
thing so I have something that I CAN program.  It seems exceedingly
unlikely that a driver is going to materialize out of the aether at this

Let this be a warning to anyone with a Chi Corporation/Computer Logics
Pertec tape controller--if you don't have the driver, you don't have
anything that can be easily used.  Both the PCTD3 and the PCTD16 use
externally-loaded FPGAs.
