Well, how about "The Triple Pic Plus"? Covers multiple 'sins'. As you've seen I just tend to give further iterations simply a version number, v1, v2, v3 etc.. much the same as software versions. Maybe not as descriptive, but it generally seems to work.
...which prompts me...I must get back to my stalled update on my first version. In the light of the current chip shortage it may be a case of starting from square one again. As the display is now a VGA monitor the speed requirement has effectively doubled, and that's creating a few hurdles as well...once I get clear of stuff currently on my plate I'll get back on the case...
Thanks for your updated version too John.

I know I go on and on about this all the time, but putting a 'positive spin' on the matter that's an example of why I do keep repeating myself. Aside from the demodulator and power supply I squeezed the MkI onto a single board, yet still added where possible plenty of fat grounds (green lines/tracks) and lots of decoupling capacitors. This will be doubly important (literally) in the VGA output version.
