Re: Vic 20 Poke Color Commands

You went through each one? I respect the dedication. This brings up the trouble with bit 3: inverted mode. When turned off (set to zero), I find it easy to see yet difficult to remember how the colors shift. The border color remains the same... I believe it's something like the character color and b...

Re: Jeff's VIC 20 Book

This is my first draft on BASIC statements. I welcome any constructive notes: PDFdraft

Edit: I suspect some of this info is not correct. I struggled with some of the statements I never use like trig functions. Just a warning.

Re: Jeff's VIC 20 Book

Please note that this schematic is already edited and redesigned and does not correspond fully to any of the three original mainboard designs. In particular, to quote the schematic itself: Yes, I know Reloaded is a redesign. And like I said, I am also aware of the many versions making a schematic i...

Re: Jeff's VIC 20 Book

Someone inquired about the idea of including schematics in the revised book again. I know very little about hardware, but from my understanding, the schematics in the official reference guide are the first version of the VIC, not the cost-reduced version. If there are multiple revisions, wouldn't it...

Thanks for this! As some of you already know, I am working on an expanded color version with tutorials and such. I welcome any corrections or additions.

WIP: Steamed Hams

I wanted to make a quick game for VCFMW convention. It's nothing special, but I wanted to share. I actually made a bunch of changes already based on player reactions. I will post an updated version soon. The ultimate plan is to have a full narrative with minigames. But I'm not sure. Maybe it's bette...

Re: Manuals in other languages

I wonder what are the largest language groups using the VIC 20 now. This board obviously attracts English users, but from bilinguals, we can deduce there may be significant numbers of German, Italian, Swedish, and (Canadian) French users. What else?

Re: Ohio-Indiana-Kentucky USA Vic-20 stuff

If I could figure out a way, I would like them. But I am in Chicago. It's a bit of a drive. I'll update if I can figure out a way. Otherwise, I hope they go to a good home.

Re: New penultimate-plus-2-cartridge

I enjoyed it the first day I tested it. I just did not know it would be the only day. :( Really hoping someone can make it useful again.
