Interestingly, the 901460-02 dump (character generator ROM) differs from
the 901460-02 and 901486-02 I posted on (and announced on
this list) last August.  In your copy, the first byte is $ff instead of
$1c, and as a result, the first line of the @ character is incorrect.

The guy who dumped the ROMs from his VIC-1001 (Daniel Benson I think) had
the same problem, and finally he dumped the character ROM to a disk file
with the SAVE command.  Did you by any chance buy his computer from Ebay?
