As grant has pointed out the pictures will not show up unless you are a VCF member. However, the screws are very similar to this in shape:
https://monsterbolts.com/products/6mm-m6-x-1-0-stainless-steel-button-head-…
I have done some more digging and I believe the screws are Button Head 10mm M6 screws w/ T30 drive. The problem is that the head diameter needs to be 9.2mm wide. The screws above (and most other one's I have found) are 10mm or wider. The HP screws I mentioned earlier are 10.26mm wide and they of course will not clear the side panels.
So again if anyone has OEM Compaq screws they want to part with I am your man.
Thank you.

Years ago I was troubleshooting an old SuperMicro beast that was running a
newspaper printing press. It kept shutting down randomly but if I hit the
power button it would come up. Then randomly go down again minutes or an
hour later.
I spent many hours testing and swapping modules in and out of this thing
>from a working machine and at one point it would only power up if the front
box that contained the power switch module and CDROM/floppy were out of the
enclosure and separate on the bench (but still connected to the motherboard
by an data/power cables). If I got a long screwdriver and earthed this
front box to the main enclosure the machine would go down immediately.
Power switch itself tested fine with a meter but I found there was a hidden
reset swtich that wasn't in use so I desoldered and swapped them over. All
problems went away and the customer practically carried me at shoulder
height around the press hall.

Ok,
A bit too new for this list but still hoping someone can help me out:
I am in need of at least six (prefer 10) Compaq 9000 Series OEM Rack screws
to mount a side panel. I believe these are M6 screws. On the side that had
the panel already mounted the OEM screws are star screws approximately 0.5"
long.
I have looked online and on some of the rack accessory suppliers and have
found M6 screws which I believe are from HP racks. Aside from the fact that
the OEM is a Philip's head (not a big deal - security is not a huge issue)
the HP ones are just a tad bigger.
The length of the HP screws should be okay (I think). However, the flange is
just a bit too big and it catches on the side panel so you can't screw the
screw in all the way (w/o damaging the side panel). The OEM star screws do
not do this.
If anyone has any spares they can part with or knows where I can order some
(and definitely get the OEM ones vs. the after market/HP ones) I would
appreciate it. Thank you!
BTW pictures and measurements can be found in this thread on VCF:

For those following from the VCFed thread I have been working on an IBM 5363
that I have managed to get running up to the IPL sign on. For everyone else
this project is being documented at
http://www.vcfed.org/forum/showthread.php?62860-IBM-5363-IBM-System-36
>From there while I know who last owned the machine (from picking it up at
their dock) me and my contact at this company have been unable to dig up the
MASTER or administrator login information. I ahve a couple leads that might
be either the username or password but so far no comnination has worked. Yes
I am aware of the old USENET post regarding cracking the login on a 5362 (
https://groups.google.com/forum/#!topic/comp.sys.ibm.sys3x.misc/Vi57cbw1ofQ
) however the CE panel on the 5363 is a lot more simplified and I cannot do
several of the steps. Also I do not have the system key but I can probably
hotwire it
Does anyone know of an alternate procedure for recovering or finding a lost
MASTER login?

I was trying to put together a minimal PDP-11/03 using a quad width
M7264 CPU and got nothing, no ODT prompt.? I'm not sure the board is
working.
Searching the internet I came across this page which described a M7264
CPU board with a 'bad' MICROM
http://www.datormuseum.se/computers/digital-equipment-corporation/qbus
Quoting the page; "Using a logic analyser showed that the MICROM without
label is not behaving well."
Anyone know how a logic analyser would be used to determine this?? Other
hints to debug this board?

I just learned from the April 2018 issue of QST that Robert T. "Doc"
Suding, W0LMD, has died. Suding cofounded and was chief design engineer of
The Digital Group, an early microcomputer company in Denver (1974-1979).
