Hi,
I was planning to convert all my RSX-11 & RT-11 RL02 disks
to SIMH container files. And for that purpose I was planning
to use 11/73, which did have BSD2.11 on it.
'Did' indeed, as the disk has gone to heaven.
So' my question is if there is a kind soul who can provide
me with a (copy) of the install tape.
Postage and such can be paid for.
Thanks,
Ed

Personally I enjoy a big Simpson 260-dash-whatever.
The Triplett 630 is in the same league.
Both have been in production (in one variant or another) since before WWII.
The RCA Senior Voltohmysts I love for their fashion sense but unless I need VTVM class input impedances, I'd prefer the Simpson or Triplett.
In terms of used Flukes, I highly recommend any used 77-series unit. You can critique the designs because of what you saw as failings of your Fluke 85, but believe me, the LCD display on any Fluke LCD DMM will be far more durable than the faceplate on my Simpson 260 or Triplett 630.
At the very low end, in the $3 to $5 range there are "disposable" DMM's available at discount stores here in the US. They are not a joy to use but they do mostly work.

I know that there has been a tremendous amount of talk about removing yellowing from vintage equipment, but going forward, does anyone have any suggestions for helping prevent yellowing of equipment on display, short of keeping them in a dark cave? I have a couple of Apple II's that are in excellent condition with minimal yellowing and would like to put them on display without having to worry about damage to the plastic.

Easter eggs. And not the software kind.

And if you're in a combat zone, perhaps you'd get a Purple Heart. True story as related in Reader's Digest Humor in Uniform section: An Army cook in Vietnam got an egg shell fragment in his eye while making scrambled eggs. The albumin stuck it to his eyeball so he had to see the unit medic to get it removed. Some time later, he was notified that he was receiving a Purple Heart. The reason cited was "shell fragment in eye." Apparently, someone was just glancing through through the undoubtedly numerous medical treatment records to discern who to present the medals to and found his record with its deceptive entry.
MARCH's booth for Maker Faire this weekend will be indoors at the main
venue (New York Hall of Science). Our maker # is 3641 if any cctalkers
are looking for us. I'm told we will be inside a modern computer lab.
Saturday night we'll be eating/drinking; all are welcome to join us.
... Well, actually, they arrived at the beginning of last week and I
didn't finish checking them against the netlist until today. My excuse
is that my notes are all on Cougar (my laptop), which is currently
refusing to boot without segfaulting in the kernel. Rather than deal
with ASUS support, I replaced it -- the replacement (an MSI U230 named
Ryoko) is far better behaved :)

They seem to have come out OK. The solder mask is a little discoloured
around some of the thinner tracks, but that's a cosmetic issue. It still
resists solder, thus it's OK :)
For the pathologically curious:
Substrate -- FR4 fiberglass, 1.6mm
Track layers -- two copper, 1oz
Layer stacking -- BOTTOM COPPER, FR4, TOP COPPER, TOP OVERLAY
Surface finish -- looks like lead-free HASL or roller-tin. It's
certainly not immersion tin or silver, the pads have roller marks on them.
It turns out I hammed the entry of the order, and managed to order two
sets of three boards, leaving me with six PCBs in total, and an
additional 130 Euro bill. Ick.
I'm still short of some parts (notably: the USB ESD suppressor chip,
some pin headers, 7-pin SIL resistor packs and 10nF 0603 decoupling
capacitors). A trip to the Farnell trade counter is being meticulously
planned, as long as I can get someone to hang around the house and wait
for my Rapid order to arrive (mouse microswitches... Logitech should be
shot for using those nasty Omron things).
Thanks,

When I was maintaining Alto Is, I put a warning sign on the machines that
stated "Avoid VD --- Venereal Disks! If your disk doesn't load, do NOT try
another machine"...
For the most part the drives were OK, but if they did fail, then the
contagion could be spread. I certainly had my share of disk crashes.
There's a reason the Alto file system had the scavanger and was designed to
be recovered...
