Anyone has the DEC font, as used to mark their papertapes, ready in machine readable
format ? ( C include file preferred )
The 8x6 format I use now just does not have the right look to it.
Yep, I am recreating some of those papertapes...

take a look at https://github.com/Hack42/Punchconverter
it is not a direct copy, but it can be adapted to do the work. We have
several punchtape devices in our collection at hack42 not speaking
ascii, so a translator is very handy. I use our GNT-4601 to actually
punch the tapes and the filename is printed up front in a human readable
font

DEC used different fonts for labeling their paper-tapes:
On my original
"DEC-08-YPPA-PB 11/10/69"
most characters are in 5x6, except the zero which is
7x6 and "-" which is 3x6:
..XXX.X
.X...X.
.X..XX.
.X.X.X.
.X...X.
X.XXX..
between every character are 2 empty steps.
on the same tape there is also a copyright message in proportional
4x5 / 3x5 format.
On my original "802 RIM 9/1/65 CHECKERBOARD - HIGH"
and original "DEC-08-AFC3-PB 8/67 FORTRAN OPERATING SYSTEM"
they use a different proportional font:
8 is coded 5x6, 0 is coded 4x6, I is coded 3x6.
Then there is a program "LABEL.BN" which I use as device-driver
to label my programs, this uses a fixed font 4x6.
For this program I have the PAL-source.

I waasn't aware there was a standardized font. Back when I was writing
lots of stand-alone programs in my 8/E's core and punching them out, I
wrote my own little program to punch text, and I got a kick out of the
fact that it was easier to do in machine language than it would have been
in PAL-D, since PAL doesn't have binary; but keying in the char-gen table
was easy to do by just turning my head sideways while I looked at the
(binary) switch register, and picturing the characters going by.
