Happy new year! You know, I find it a little hard to accept machines made
in 1999 as being 'classic' :-)
Was the Tube ULA (or the Tube interface) fully documented anywhere?
Obviously a pinout of the ULA exists, as does a general description of
what it did. And I think the source code to the drivers on at least one
side were published somewhere (I seem to rememebr a book on the Master
512 the contains such sources). But I didn't think there was enough info
to necessarily correctly implent the ULA functions.

* A drop-in
replacement for Acorn's TUBE ULA would be nice - I used my=20
last remaining spare a couple of years ago, and still have a couple of=20
devices with dead ones - swapping in from a working unit is a real pain.
Hmm, shouldn't be too hard with modern programmable-logic devices.
