Re: Fun with CBM arithmetics
Seems like we're zeroing in on the bug. I had hopes it would 'only' be the conversion routine which was broken, but it's (sadly) most probably the multiplication at fault: :( 1 A=.75+59E-9 2 PRINTA*1E9-7.5E8,1E9*A-7.5E8 3 PRINT(A+0)*(1E9+0)-7.5E8,(1E9+0)*(A+0)-7.5E8 4 PRINT(A*1)*(1E9*1)-7.5E8,(1E9*1...

Re: Listings aus CPU im Roeske Verlag (GER)

Re: Forum moved to new host
At least for me, the internal links containing "[...]sleepingelephant.com/ipw-web/bulletin/bb/[...]" now function again correctly! :D :D :D There are some older (internal) links with "[...]/v-web/bulletin/bb/[...]", which wouldn't work - but they are only far and in-between. In a...

Re: The end of the ROM based PLA for the 64
The VIC-20 has no (single chip) PLA to generate the various chip select and other timing signals, that job is done by several TTL chips.craftsman1234 wrote:Will it also work in a Vic-20?

Re: Challenge: Create or Delete Lines from inside a program
Would Photoshop for Windows make MINIGRAFIK for the VIC irrational? It probably would, if it were not for the fact that Photoshop and its kind do not provide substantial help to actually import images/pictures into the VIC-20. Given the premise, that all this is still about programs/games/applicati...

Re: Challenge: Create or Delete Lines from inside a program
Yet you keep soliciting for help which constantly 'requires' you to think out of the box. A good deal of your problems turn to non-issues once you'd use a better set of tools. Sometimes you behave like a strange mechanic who not only insists to tap threads into the bare metal (which is quite usual),...

Re: WIP: Doom
Judging from a thread over at lemon64, VIC Doom is already gaining a good reputation as RAM testing tool. :lol: One should say thank you to Torsten for pointing out there that TDE isn't needed in VICE (after all, VIC Doom runs happily from SD2IEC devices as well), and 32K + 3K RAM expansions *are* r...

Re: Challenge: Create or Delete Lines from inside a program
It requires the use of the Programmer's Aid cart. [...] ... which, for one, is contained in the Mega-Cart. I know you own one. Especially the toolkit of the Programmer's Aid cart is only used during program development. All the commands can only be used from direct mode. Which also means that a pro...

Re: Suggestions for GP cart
Can you point to a link or document that explains the idiosyncrasies? Main issue was, that in Super-RAM mode, the RAM could only be switched in whole 32K blocks, which made the implemenation of the RAM Disk (or any other use) difficult to say the least. * I found 8Mb (1MB) RAM and FLASH for not a t...

Re: Release: Pooyan
Nice!
When I played a second stint (and I did considerably better than on my first try), the game didn't update the high-score display.

Re: Fun with CBM arithmetics
and dont forget that the typical error is 1 or 2 _binary_ units (powers of two!) Yes, that's what I meant in the first place. well, i dont know according to what standard (if any) the floats in cbm basic have been implemented, so its hard to tell whether this is acceptable or not. The implementatio...

Re: Fun with CBM arithmetics
groepaz, this is not just the occasional rounding error with 1, maybe 2 units wrong in the lowest place we're talking about here. It's a *defect* in the float to ASCII conversion which happens under reproducable circumstances and which, when happens, outputs a grossly wrong result. If you enter PRIN...
