Heh. I've got the CPU Techref from Dave (which I suspect came from you
originally - looks like your writing on the envelope!). Even that
mentions the T4 as being extremely rare.

Yep, I didn't expect it to be too difficult. I can't hang onto the
machine for long as it's taking up car space in the garage - but I am
tempted to put it back together here and have a play with it :-)

Yikes. This one does work apparently; it was last booted only a week
ago. 1280x1024 isn't bad considering the age of the machine...

Hmm, not sure if I have cables between monitor and chassis yet - I think
they might still be at Dave's place. 

I really need to talk myself into *not* attempting to keep this machine
though, no room! :-)
