Re: Maxigrafik

15 downloads of "Maxigrafik-Screen.rar" (mine included) without any other replies thus far leave me at least with some question marks above my head. At least, Armando didn't make it *that* simple to assess what is to do with the files "d1d-scr", "gasket-scr" and "s...

Re: Utimem or Final Expansion?

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 ...

Thank you! That's a really nice and funny sprite sheet. :)

Minipaint and Minigrafik are both amazing utilities.

I'll think over another utility in the batch suite to extract the bitmap data of single sprites in a similar way I did with VicShroom.

Re: BASIC 3.5 on a VIC?

I know of a port for the C64. Obviously, the prospects over there were much better, given the necessary (and available!) memory and also the graphics capabilities. [V]3.5 is found on the Commodore 16 and Plus/4. Even thought it's numbered lower than [V]4.0, it's more advanced. Yep. They really shoul...

Re: Vic 20 Black screen

i have just left it on the black screen with led on for about 20 minutes and it turned itself off?? What did you expect? That the initial damage inside your VIC-20 would repair itself? don't have a multimeter. Then buy another set of working VIC-20 and PSU on ebay. Using either a defective VIC-20 (...

Any chance you'd make the concept art available in its original MG format to view it in MINIPAINT? :mrgreen:

Re: Utimem or Final Expansion?

So the then we get into the crux of the matter. Every VIC20 has an expansion port. Outside the US many VIC20 owners only have a tape drive. Who told you that nonsense? You can count on that every VIC-20 user actively pursuing this hobby has a feasible mass storage solution at his hands . If someone...

Re: Utimem or Final Expansion?

I'm working on two projects that would be impossible without banking RAM/ROM. How can you be sure about that? Given a much more faster file I/O from SD card (as I wrote, in excess of 100 KB/s), a full RAM expansion, and a little thoughtful working set tuning should be able to give a comparable perf...

Re: VIC cartridge PCB eagle

Any comments are welcome. You should consider routing the data lines CD0 and CD1 with vias, and CD3..CD7 between the left-hand side pins of the chip. No reason to copy the original design in that point really. One could easily route a trace between through-hole pins already in those days; nowadays,...

Re: Utimem or Final Expansion?

I beg to differ. First of all, FE3 predates Ultimem by quite a few years (2009 vs. 2015/16), so it's no wonders a few weaknesses of FE3 had been ironed out with Ultimem. The general set-up though shows no big differences: both feature a large, banked SRAM and likewise, Flash-EPROM. Ultimem contains ...

Re: Two VIC-20 Releases for Gubbdata 2017 ...

I wish I had the super-expander or the penultimate so I could try it on my real VIC. :( In the meanwhile, emulation with VICE on a PC is a perfectly legit way to proceed with the files. With real h/w, you'd anyhow either have to transfer the storage images to a floppy disk first, implying use of a ...

I will have to try these out later, I'm always exited to see how people write this software. For everyone who is interested to take a peek at the "Castle" picture within Picasso, I have converted the *.prg file back to Picasso format. The picture consists of two files, "0CASTLE"...
