Subject: Help with Xerox 820-1

       Xerox 820 boards had the WD1771 disk controller. Won't do double
density. There are those who have managed to hack the board to do DD, but
it involves a daughter board, doubling the CPU clock, hoping the DRAMs
can run that fast, etc. etc. Quite a project.
       Maybe someday (in my spare time [:>) I might consider tackling this one.
Mine has a pair of double sided 5 1/4" Remex ($29.95 !!!) drives configured
as a: thru d:. Works OK, but only 81K per logical drive. DD would sure be nice!
