[comp.sys.cbm] VIC LARGE characters

mac@harris.cis.ksu.edu (Myron A. Calhoun) (03/20/90)

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.

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...
