Williams tube.
Gr¨¹?e, Carsten
You might be talking about the loose tube in a box at the bottom of
the picture. I mean a rack mounted unit between the two PCs.
Yes. See the picture at
(because of the inexplicable restriction on sending attachments on this list, I just put it up in a random location. Copy that into the groups.io archive if you can stomach navigating that entirely unneeded bureaucracy) ¡ª zoom in to see the faint green image of the bits.
There are
two scopes and a third thing, in the rack, that also looks like a
scope. A Williams tube device has no front display because the front
of the tube is covered by the read-out plate.
The problem is ¡ª how do you debug a Williams tube?
I seem to remember that the makers of the Manchester Baby (SSEM [1]) just put another tube on the same signals so they could see what was written to the storage tubes (ah, [2] has the details). During restoration, they couldn¡¯t get the original size display tube, so they have a half-size in the rack now.
BTW I tried getting in touch off list but haven't heard back :) Would
you mind checking :) thanks
Everything is on its way, thank you.
Gr¨¹?e, Carsten
