How many colours can the 1241 display?

I think it could only display two colours using some trickery with a dual (Orange / Green) phosphor coating and varying the beam voltage to choose between colours.

RAPo:
Using an LCCS (Liquid Crystal Color Shutter), the LA can display three colours (red, green, and yellow/amber).
Normal is so-called regular colour video mode: colour characters on a dark background
A Highlighted colour video mode: colour characters on a colour-shaded background for signalling important information
For input/menu fields, a reverse colour video mode: dark characters on a colour-shaded background

A lot more than I have ever paid before!

You are right, these are getting very expensive even when sold as untested  & possibly with drifty A3 cards. Time will tell if I made a good deal or will regret buying them.

I bought some new rubber bumpers for my new to me 34401A. Looks like it was used in a rack so no rubbers. This just makes it tidy.

Took the time to also unlock all the locked features such as the TEMP menu.

Also a BME280 turned up so I can start to log temp and hum with my 10V data.

Time to learn some more coding.

Got a Pro'sKit SS-331H vacuum desoldering station. Not exactly today, I ordered it during one of those impulsive shopping sessions earlier, but yesterday and today I had an unexpected chance of having to use it.

It's pure delight guys. If you need to desolder a through hole pin even once in your entire life, a tool like this is absolutely worth it.

Now I need to find something simple, compact, and decently performing for SMD desoldering. I wonder if there are any T12-compatible tips that have a rectangular cut sized to fit standard 1206, 0805 etc. sizes to get away without having to use tweezers and use just a single tip. I guess I could make one myself by making a cut in one of those wider tips, but this will destroy the plating, so not sure if it's going to work well.
