Subject: In search of VAX 750 front door and CPU spares.
Please let me know if you know of any. Picked up a 750 today, and will be

Ian,
I think I have the CPU spares for the 750 I have :-) Which ones in
particular are you looking for?

Hello,
I got 2 x NCR PC4i computers. One is running fine at the moment but the
harddisk has some problems.
The 2nd one had a dead CPU and Bios rom. I replace both but got no beep
and nothing on the screen.
The PC4i has a 'rack case' for the motherboard. Changing the case shows
the same prob
Oh, that would be great to have. I have a 8354 (the last 4 is processor
count I think). Mine is in an unknown state.
I have some floppies, but not 40.
/P

Does not require three phase.
Complete system, includes sirius video and other fun stuff.

Needs to be gone in a week or two- had made other arrangements but they
have fallen through.

Hi,
I'm willing to spend a bit on an IBM 3290 at this point. If you have one,
and want to discuss "a bit", please contact me.

Speaking of lubricating oils... I've recently been cleaning/etc some of
the ~4" boxer fans that the earlier PDP-11's use in large quantities.

If they use sleeve bearings, take a close look at the material.. does it
have the sintered look of oil-impregnated bronze (Oilite)? Are there
channels in the bearing to allow the distribution or retention of grease?
Those fans tend to run at pretty low RPM, so a very light bodied grease,

White lithium isn't by any means ideal, it's too sticky. It's carried by a
solvent so it runs freely and can be sprayed, but once the solvent kicks
off, some of it's almost like paint.

It looks like copper, actually; it's quite reddish. (The central pin seems to
be steel of some sort.) But I'm not familiar with Oi
Ok, so there's an annular groove cut mid-way along the length of the shaft.
That might well be for retention of lubricant. You'll have to forgive my
assumptions about low RPM operation - I took these to be the typical
'Muffin' type fans, that run about 600 RPM.
This is a long-shot, but does the gr

Depends on the formulation, I guess. The white lithium grease

Yeah, that was my guess too.

Google "electric motor grease". You'll get lots of words.

Perhaps five years ago, a friend gave me some Atari 8-bit gear,

(which is undoubtedly no good now), and a 1050 floppy drive, but no
software. The stuff has been in storage in my mother's basement until
recently. I just kludged up a
