Re: Unpopular opinions thread

Not sure I follow. What do you mean by "US English" layout being supported by ASCII? ASCII predates pretty much any keyboard layout.

Re: Heathkit ATX-10

Those are quite nice. I think it is actually an HTX-10, H for Heath. Same as the Zenith ZTX-10, Z for Zenith. They are neat little terminals.

Re: Have any of the selectrics ibm turned into old computer keyboards been found in the wild/alive?

There was a specific model called the "I/O Selectric 731" that was produces with all the electronics and hardware to interface for both input and output, hence the I/O tag. There are few pics here: https://www.vaxbarn.com/index.php/other-bits/362-ibm-731. Some of this was used in the later Selectric...

Re: Cleaning a plate without removing switches

Hypersphere's instructions are excellent. I will add that I find having some foam swabs in addition to cotton ones is useful as they come in several sizes and don't leave fibers on sharp edges. I find these small ones are useful to get in the narrow areas and crevices. https://www.amazon.com/Semi-Fl...

Re: Making a Secure Keyboard

Some of the teensy boards have a microcontroller with a small amount of eeprom (1K), which is persistent, but no other persistent memory. More could be added by connecting an external eeprom or disk storage such as an SD card.

Looks great! I agree with fohat, the ANSI enter/backslash and backspace mod is well worth doing for the 2u backspace and does not require any non reversible modifications.

Definitely the slider over dome. Keycap profile is wrong for 725 series (i.e. space invaders). Space invaders has a lower profile and in 99% of cases a stepped caps lock key. I have never seen an RT-6xxx with space invaders. RT-8xxx indicates space invaders.
