I have had a major health incident which means that I have been unresponsive
for several months. As I need to move in closer to town, I will be disposing
of what remains of my collection (Things like: Altairs, Imsa, PET 2001,
Apple II, TRS-80s, lots of S100 carts etc.)
Best Wishes Dave.

Bill,
If I were on such a tight schedule, I would as you say rent a car,
but one-way, from Gatwick - drive that night late to a hotel in
Milton Keynes about five miles north of Bletchley.
About 90 miles Gatwick to Milton Keyes - two hours or so late at night.

Another apocryphal(?) story is that a FASTRAND unit lies today at the

You could stand there watching through the window on the side of the
