Hi M.,

Long time indeed.  I guess I did desert for a while, but... came back.

Glad to hear that you found Cambridge amusing; give me a call if you
ever find yourself in these parts again.  Canada was good fun too, if a
touch on the rural side.

Heh, good point.  I guess a fallback position if you can't find the
password would be to locate the password file on the boot disk using an
ADFS disk editor on some other machine.

You need some version of DFS to make the Tube work but, AFAIK, it
doesn't really matter which one.  Personally I'd fit separate ROMs for
DFS and ENFS (I don't think there was ever an ANFS release for the B),
but if sockets are at a premium - and you don't need 1770 support - then
a DNFS with DFS1.20 and NFS3.60 would be fine too.

No idea to be honest.  But, according to the scanned schematics, it
looks like the Master 512 used a 10MHz 80186 with 150ns DRAM.  So I
guess you ought to be fine at anything up to about 12MHz with your 120ns
parts.

Which reminds me, I should redouble my efforts to find some RAMs to go
in my 80286 board.  Does anybody know what devices are needed there?
