 True, but I wonder if they didn't, somewhere along the line, use
 their Z-80 expertise to adapt Dr. Dos.

 I don't know how fast the Z280 was, Ok, I looked it up. The z280
 is no longer made. However, the z380 is available. It runs 18mhz
 top speed. The evaluation kit is only $575.

 They also have flash memory Z80 derivitives that run up to
 50MHZ, but I didn't look up their prices.

 It could be that last is the one in the scanners.
