Building a PLC

[iant]

you also need some Wipe Off Memory Buffers (WOMB) to make sure it can be cooled down

lets assume 1 MBits of memory consuming 1 watt each, you will need another truck for the 1 MWgenerator. You could use a Roadtrain and make the signal lights with the PLC.
I do it with an arduino also consuming 1 mW (where is the shift key)
a good yoke

Don't forget to include a Baudot paper tape reader so that you can back up the code. Worst case scenario if the operator loses the tape you could always Telex another.

Where is the swamp cooler to cool all the tubes? Never mind about the moisture content in the air shorting or corroding the tubes.

It comes on a salt bed - pretty big

What self-respecting vacuum tube computer would use tape memory?

It's Diode ROM:

you will need a decent DC power supply as well

and for the Write Only Memory, there'll be a Binary Allocation Table...

Look at the date of the first post....

It started as an April's Fool joke, but then evolved into the old Smoke & Mirrors, Inc. rides again!

The Smoke & Mirrors corporation started in 2006 with Thread 20167, Post #6 from Geninus in Training. I think it is still in business! I know the Genius the Project Manager is doing great, and the Communications Director, the Profreader, the Converter, the Finance Officer, the Suds Dispenser, the Scapegoat (me), and some others are all still here. A few (the Mediator for one) have passed on.

The offical company name did not finally get settled until Post #106 from the CEO Terry Woods.

I'm going to give it an ENORMOUS WOM (Write only memory). Think 1 Terabyte will be enough or should I go with unlimited memory? The tube circuit for that isn't all that complicated if I remember correctly.

Why stop there? For a few tubes more, you can build an early version of a StarTrek transporter.

The current draw from the tubes easily explains the need for dilithium crystals...

These acronyms drive me nuts especially so when I forget what they stand for.

What is the differance between a
WOMB
and a
WOMBAT

and then what about a
DINGBAT

Here I have designed pneumatic PLC. There is pneumatic generator who gives 24V out for Cubicle light and RJ45 for pneumatic Ethernet-IP communicattion for other pneumatic PLCs.
