If your image-converting program is smart, it will let

use a 0..255 grey palette for a GIF. If it's true line-art with
no greys, it'll have better compression with almost any palette
that has a black and a white in it.
I'm using the PBM tools, so I just made all the tiffs into pngs, which
work fine, and they're uploading now.
And I'm extremely jealous of that computer. :-)
It gives me
flashbacks to glorious old '50s junk I'd find in dumpsters or
auctions or rummage sales and disassemble.
I feel lucky to have it, I can assure you. It's actually the perfect
machine, though architecturally it's a bit bizarre and limited, it's
solid state yet first-generation architecture still. The LGP-30 is far
more complex, electrically and mechanically, plus it's 800 lbs! Other
than the memory and Friden, the LGP-21 is just a bunch of transistors.
It eats 300 watts from the local nuclear or coal station.
(It really is a first generation arch, like the '30; arithmetic only
order set, non-character-oriented, no index register, drum, serial, one
accumulator, though it has hardware subroutine support (barely) with the
R instruction.)
