Does anyone know where I can get get some VIC-20 BASIC program listings to type in, for old times sake? Anyone got any listings /articles from magazines, etc, scanned to PDF? I don't where you can find listings, but I recently processed an already scanned listing, and it was quite some work to get ...

You're halfway done, but first some bad news; your memory expansion has to have a possibility to switch which memory block(s) it maps into. Your 16K expansion probably maps into address $2000, just extending the Basic memory, while most cartridges maps into address $A000 (and $6000 if it is a 16K ca...

The moderator will have to confirm your request, but maybe he is busy. The latest news is that Brent will spend the rest of the spring organising what already is there, and then give a report how to continue the archiving and preservation from there. If I had the time and incentive, I would start to...

No, the software you develop for the Super Expander et.al. requires the tool to run. The Programmers' Aid is slightly different, as the commands it adds mainly are for helping development rather than being useful within the program itself. There were a lot of more or less free graphic tools out ther...

Anything that plugs into the game port then? I believe it is ten times more common to have an Atari-style joystick than having a pair of paddles or a lightpen or something even more obscure, which means that a paddle-only game will be difficult for most people to play. There was a paddle-only Atari ...

Two switch Atari? I thought that was a VCS-CX2600A, which is the four switch version with wood panels. Are they more interesting than the first six switch version or the later all-plastic ones? Dunno about the price vs contents and condition.

Actually, I have never fully figured out how to make use of the USR function. In theory I know how Basic will access it, but I never found a need or usage for a ML routine I couldn't SYS and PEEK values from. How about self-modifying Basic? :lol: I'm not saying I could manage to get a program workin...

Pure luck united me with this game and the others I found that day including a boxed cartridge copy of Ft.Apocalypse for the atari 800. Too bad it wasn't Fort Apocalypse for the VIC-20, as that cartridge would be COLLECTABLE if ever found/existed. Of course, if you are eager to sell, you could cont...

Anyhow, I wrote to the vic-project list on Tuesday, mentioning both this forum and the group vic20files. Brent, the coordinator had no objections with inviting and uniting people with the same views. Chris, how active are you with the vic20files group on Yahoo? I think technically it is close to imp...

Hi Chris. I was going to mention this site to you, Dong Feng and whoever else who would be interested on Vintage Computer, but forgot. I think the rules are quite OK. Maybe you should add that POKEs are ok, but no SYS or USR calls (which also prevents from smart using of ROM routines - dunno about W...

From what I understand, two of the three complete sets of the Ultima game are or were owned by Ultima collectors who didn't even have or was interested in getting a working VIC setup so they could see if the game would load. Leo might be the exception to this.

My big brother bought his VIC-20 in 1984. Two years later he upgraded to a second-hand C64, so I bought the VIC from him. I didn't own any cartridge games, but added a 12K RAM expansion[1]. Another one or two years later, I "inherited" his C64, so in 1988 I sold most of my VIC-20 apart fro...

I would probably make my own (illegal) copy, possibly even photocopy the cover if I got the nerve and sell the original as soon as possible. :P It is not certain that what sells for $3600 today would sell for more than $3000 tomorrow. Of course, you can set a reserve price and withdraw the item from...

Nice idea, although I would suggest 20 lines of Basic if you want to get anything playable. The reason why is that most games are built on decision making and comparisons (IF), and as you know there is no ELSE statement in Commodore Basic to continue on the same line if the condition was not met. Of...
