I can only say that they fail often. We have replaced lots in

Sometimes the failure has been rather catastrofic with blown

I've seen a memory assembly from a PDP-15 and it looks very much like
this. Also, if each connector pair corresponds to one bit it adds up to
18 which matches the word lenght of a PDP-15.
Of course, PDP-1, -4 and -7 used 18 bit word lenght, but they were not

I believe many would appreciate that. I'm lucky though and have spares
enough for my machine.

Indeed, you use what is at hand and what you are comfortable with.

Speaking for myself, yes.
I have a Teensy 2.0 lying at my de
will become a USB
interface for my 11/70 front panel. The Teensy was the simplest/cheapest
way to get a usb interface with lots of I/O pins. (Why usb? to get a
connection to simh on one of those newfangled Pi-things)

Well, that was obvious. But it raises an interesting point, today you
can cram a whole computer in the footprint of the simplest DIP carrier.
For the same price point an

I see it on the small scale all the time. Such as Rod's new front panels
for the 8/e. Or the various replica kits for early
Run of the mill PC clones are rather booring. But brand names, oddballs
and first are always fun. I wouldn't mind to have the first DELL machine
in my collection.
I have a DECpc 433 with matching SCSI expansion box. A desktop machine
with some interesting solutions.

What is the difference between an RK06 and 07 ?
Is it capacity?
Could this pack be used to align an RK07 ?
I ask because we have an RK07 at the Update Computer Club.

I believe you. I found this on youtube, looks like the have some sort of
generator or boiler external to the shovel. Perhaps it's compressed air?
