redid it again and got a slightly smaller .gz size (now 1471318) and it 
fit! the max size on that floppy by my calculations is  1440 x 1024 = 
1474560 so it's close, ~3kb+ space left. i think i used the old 
phase8-image the first time. it definitely helps to be organised and do 
regular cleaning ...
