Is it possible to get a copy of the Mincbasic and RT11 disk? willing to
pay to get it for our Mincs.
+1, please!

Very bad idea. They just don't look good enough. And they can't meet the
real colors.

This is perhaps an obvious question, but have you asked a professional printer
for advice? They are likely to offer to silk-screen onto Perspex for you at a

This is pure theory :-)
Doing "some silkscreen" is pretty easy, yes. You don't need too much for it.

They are trivial to access. You just have to cart your lazy asses to Fremont.

Right, that comment was more directed to the discussion here about baud rate
variation.

That is an immense pdf and collection. Some time and effort gone into that!

I wonder: how technical is the 'technical' content? I have been looking
for even pinout-level documentation for my VAX 6000-66
Ok, this will be a tough one.
I've located a Sparcbook 1 technical manual. It has a lot of good
information in it with schematics for the electronic.
It seems to be missing schematics for the power supply in
it. This takes the single input and creates all the other
voltages, like +-12V and suc
I'd love to get what you have with the remaining schematics and
technical info.
I don't have any such documentation right now or where to find any online.
thanks

That is true of all traditional UARTs. For fancier parts intended for
