In BASIC, where did the short cut of '?' for PRINT originate?
After following a discussion on the CoCo list I thought I'd ask here.

Well, I got a TK50 drive off eBay, and I have some questions about it.
First, is there a (transition panel/bulkhead/distribution panel/whatever
you want to call it) connector for it? I'd really like to use that if
possible. It came with a Micro-PDP11 style hookup, which is just the
TK50, ribbon cable, and the controller that goes to the drive.
Secondly, how do you clean these drives? Is there any procedure I
should use to clean the unit before installation?
As always, your anwers are much appreciated.
TIA
Julian

Any one know the Specifications (inside hub diameter, outside diameter,
thickness) of the DEC RKO7K DC Disk Pack Platters?
Thanks for your time,

I have a feeling that a while back someone was going to update the classiccmp
wiki with tips about taking photos of PCBs.
a) Did it ever happen and,
b) Where's the wiki gone!? www.classiccmp.org/wiki appears empty of any
information!
I've got a few boards I'd like to grab photos of now I'm back in the UK and
thought I'd educate myself a little first :-) (results in the past have been
somewhat mixed)

Hi folks,
I'm looking for XENIX installation disks, documentation, and other
assorted paraphernalia for both the Apple Lisa and the Altos 586
series of machines. Actually, any early (pre-1985) XENIX stuff is of
interest to me, but those two machines are the ones I'm working on at
the moment.
If you have anything that you'd be willing to either copy or let go,
let me know off-list, and we can work out the details. If there's
interest, I'll summarize what I find to the list.
Thanks very much,
Rob Ferguson

Yes, there is also 11/2 and 11/23 than usualy can be found cheap.
At the single board level there is the 11/21 falcon card.
If one wishes to build from chip level defunct VT240/241, HSC50,
RQDXn controllers and a few other DEC bits can supply a T-11 chip
(base PDP11 on a chip).

Minix on PDP11, Not that I know of. It would be interesting.
