  I have a PC Transporter on ebay right now.  Probably the one you're talking
about.  It's a V30 chip, but mine has the optional 8087 math co-processor for
even better speeds.

   I have in my hands right now an Enhancement Technology PDQ II 68000 board
for the II.  256K of RAM. The McMill mentioned is not a true 68000, but a 68008
chip.  The McMill ran at 1 Mhz, the ET board ran at 10 Mhz.  The McMill was
$195, the McMill Plus was $295, the Et PDQ II was $695.

  According to a December 1985 A+ article, the 3 boards mentioned above are the
only 68K boards available at the time.
