Windows30

I installed Windows 3.0 for the first time today* From seven 720 kilobyte stiffy** disks. And it worked first time.

 

* Windows 3.1, I’ve installed countless times. Windows 3.0, never.

** Yea that’s what we call them here.








I mentioned previously that I figured out how to make a new display for an FT-x90R. My own rig is still in pieces ‘cos I’m not quite happy with the software yet (or actually, with my reverse engineering of the display protocol, but it’s the same thing in the end).

But Dave ZS5DF wanted his rig fixed so I fitted a new display, even though it doesn’t have the F key “P” priority display function in firmware yet.

Two filament bulbs, because the replacement display needs light from the right-hand side and the S meter is on the left-hand side.

Component cost is close to R500 which almost puts it in good-money-after-bad territory but I like these little radios.

Younger kid had to build an electric motor for a school project. Having a garage full of stuff, it was no hassle to find everything required to build one.

motor

I made her wind the coil.

But the question is, how do kids complete (or even conceptualise) something like this if they don’t have a Wouter around the house?

C1166

This is a C1166 Pulse Tetrode made by English Electric, who also made transistors. Good for switching 17 500 volts at 15 amps. But only for 1 microsecond every 1 millisecond (1T4 and AA battery for scale).

The filament alone needs almost 60 watts (9 amps at 6.3 volts).

Quite useless unless one wants to build a glowbug radar or something. But quite marvelous in a way.

“Hello, Crazy Mo’s pizza place, how may we help you?”

“Well we’d like *yadda* *yadda* *yadda* *yadda* and a mac & cheese”

“Would you like the mac & cheese with penne or tagliatelle?”

Mahala gratis verniet and for free, nogal.

And it seems to work, that’s indeed a 4.7k resistor.

Look at the ridiculous scale on this thing — not only uA but nA as well. Why would I want to measure a nano-amp?

I think this will become part of my permanent test setup.
