WOW.. I thought I was the only one on here with an 8800.  Mine is a B
model with the Quiet bus installed and runs at I think 8Mhz.  But its
been a while.  I also have the Zilog Z80 board in it as well as a very
early modem and terminal driver for the TV set type display.  And the
whole shebang of 64K.
