Re: Why is the Machine Language Monitor cartridge so expensive?

I just noticed this old thread after coming across a listing for Machine language monitor is now going for over b£100 at least, but even stupider a Stonechip Vixen VIC 20 Switchable 16K Ram Expansion Cartridge is going for £170... Why are people paying that price for these things that are completely...

Re: What size of memory do most VICs have now?

I don't see how that conclusion follows from the data. Well, if keeping your program as low as that is only catering for 30 people out of 218, that's just around 7%. So it in't worth trying to, compromise or cut things to, fit your program into a lower amount of space when more people have access t...

Re: Why is the Machine Language Monitor cartridge so expensive?

I have noticed that alot, if not all, of the high priced items appear to be continually re-listed though, and nobody is actually buying them. So, is it another case of people trying to sell high because they see stupid high prices on ebay, but nobody is actually buying them. Looks like the person wh...

Why is the Machine Language Monitor cartridge so expensive?

Just something I've noticed when looking at ebay lately... Most other Commodore cartradges seem to be fairly cheep to reasonably priced, but the VIC-20 Machine Language Monitor cartridge always seems to go for what seams like silly high prices. I recently bid on one which was sitting at around 10 to...

Re: What size of memory do most VICs have now?

Thanks for this, The game I was thinking about making is a sort-of RPG that uses the same basic engin that I made for Trapped, but expanded to include indoor and outdoor locations. I started this also on the Vectrex before my vectrex died. So the memory used basically turns into the size of the game...

Re: What size of memory do most VICs have now?

I was thinking about seeing if I can convert my 'Trapped' game for the Vectrex to the unexpanded VIC. This is just shy of 5k on the Vectrex and I already have an idea of how I would do this on the VIC. https://www.youtube.com/watch?v=ZU2LigCTyus https://drsnuggles.github.io/jsvecx/?rom=Trapped But I...

What size of memory do most VICs have now?

Ok, so obviously they still all come with 5K, 3.5k usable for basic. What I mean is in the current VIC community, do most people only have up to the origonal 16k expansion. Or is it common for people to have their VIC expanded to 32 or 35K? Basically, if I were looking at making a game, is there a b...

Re: the C64 maxi loading vic20 games

The naming convention also lets the VIC emulator know whether or not the image is PAL or NTSC.
