I seem to remember it was written in Pascal on TOPS-20, possibly at KTH. Quite possibly, but I can't recall offhand. I have (had) some prank fonts, as well as my own designed fonts for the Z-machine. And I know there is a GIF viewer out there, which uses soft fonts to render pictures on some VT terminals (not sure exactly which ones, though...).

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) Julian -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.
