Done. My 128DCR reads 5.02V between pins 2 and 8 of the video port, and
my 128D has 4.94V. So all 128s should have 5V there. I also tested a
C64C (E board, ASSY#250469 for Richard), it also has the 5V there. And
now, surprise! I just grabbed a C64B (#250425, judging from the diode
fix at the cassette port and the 1 chip clock circuit, I didn't want to
open the machine) and it also has the 5V supply there. I didn't know
this before. So, starting from 1984, all C64 and C128 machines have this
feature. Strange they never mentioned it in a user's manual.
