Assuming you're aware of this page:

Johnny, wasn't there a version of Pac-man using DECDLD graphics written in your neck
of the woods? I seem to remember it was written in Pascal on TOPS-20, possibly at KTH.

I know this is a bit off-topic, but I was playing around with the DECDLD commands in the
VT220 programmer's reference guide to make character graphics on the VT220 (I'm
actually using Mac240, a VT220 emulator that has full DECDLD support at a VT220 level)
I'm having a problem getting characters to join at the top of the cell. The top two
pixels don't seem to meet.
I see some material about VT320 but the addressing of the matrix seems quite different on
that terminal.
I'm using 7-bit encoding to create the characters. Do I need to use 8-bit in order
to use the full matrix?
I'd be surprised if anyone on here has actually messed with this, but I thought it was
worth a shot.
I can also toss my work at whoever has a VT220 lying around to see if they can test it as
well.
Any input is appreciated (as long as I can decode it, ha ha)
