Thank you Mike! Now Buck Rogers is working. Amazing how much you know!

Now I've tried some cartridge games. Some of them are positioned wrongly on the screen with the leftmost part outside of the visible screen. Is it possible to change that? I thought I could use the cursor keys but it has no effect. Also, I think there is something wrong with the Buck Rogers image be...

Thank you, Mike! I feel that I'm learning quite a lot by your explanations .

Thank you Mike! So, I think a key point in your answer to my question is that the address to load to is stored in the PRG files so I don't need to specify that explicitly. So, basically, if I want to load and run Buck Rogers, I assume that I could just give the following commands in direct mode, ass...

Hi, I'm pretty new to the VIC-20 and I'm wondering how to load games from gamebase20_v03 to a real VIC-20... If a game has a000 in the file name, such as Galaxian-a000.prg, I guess it should be loaded to the cartridge area (a000), which must contain expansion RAM, but how do you do that in practise?...

I also started with a C64 and never had a VIC-20 back in the 80s. I bought a VIC-20 in recent years though (or actually two because the first one pretty quickly got some issues and I don't have knowledge or interest in fixing HW issues) and I think it was fun to play around with, to learn what capab...

Seems like it was pretty common that countries developed computers for their schools. In Sweden, we used to have ABC80 and Compis for that purpose.

Wow, really impressive!

If enough of those people share the same dream, they could pool their money and offer it to someone who can programm Mega65 full-time. Somehow like a reverse kickstarter. I remember some years ago there was a project called "Commdore Bounty" that worked on a similar concept. As I remember...

Yes, very good, thank you!

Well. I don't agree with you there but it is ok with me, people can't agree on everything.

Well, the 1581 seems incompatible with the DIRECTORY command in BASIC V4, at least when I try that the directory listing usually stops at some random place. I'm having no problem with the DIRECTORY command with a 1541-II though, or if I do LOAD"$", 8 followed by LIST with a 1581. Well, I ...

Hardly any VIC20 owners are going to have a 1581. People went beyond the VIC-20 at that time, with a C64, C128 and - possibly! - a 1581. As it happens, the 1581 *works* with their VIC-20, that people just might have kept. For whatever reason. It was, and still is, a working solution for big applica...

Nice, thank you .

BASIC V4 has a primitive machine language monitor that you can start with the MONITOR command. Does anyone know the commands you can invoke in the monitor? I haven't been able to do anything except showing registers with R and quitting with X.
