A visually-impaired ham in this area wants to get on packet radio. He owns a minimal-memory VIC-20 computer, but has trouble reading even its already-large letters. Is there a relatively easy way to make even bigger letters? I've used a VIC-20 on packet, so the interfacing and terminal-emulation stuff I can do; but I've never designed my own character set or done other "exotic" stuff (and my cbm-guru son is off at college!) Any help would be greatly appreciated. --Myron. -- # Myron A.

Yes, the VIC-II chip has a mode where it generates double high characters; we found this sufficient at the local high school (doubling the width results in an almost useless 11x12 display... 22x12 is almost usable). I do not have the code for this. It eats RAM to define the new character set. I don't recall details, but if you really want I could probably write it in an hour or so. Send mail... ... Joe
