May I introduce you guys to the command line program PETCAT, which is part of the VICE distribution? Since you have Basic listings as mostly text files, you can start a command prompt and use this little program to generate a tokenized PRG out of a Basic listing. No more need to paste text directly ...

Aren't there other sound [..] chips that can be mapped to the Vic. Oh yes! I expect you could map an AY-3-8910, SN 76489 or even Atari POKEY quite easily. All three of those chips produce sound equal to the VIC chip, just somewhat better frequency resolution. The SID outshines all of them, although...

If your 1551 involves shipping, I hope it will arrive safe and sound. Most 1551's sent by any sorts of post service tend to arrive smashed into bits.

I can say as much if I hadn't had access to first Amigas and then PC's, I would probably never have touched machine code programming. It is way too complex to run natively on the VIC or even on a C64/C128 to be worth the trouble. Basic is mostly fine, since it is an interpreted language. Anyway, thi...

I believe if you have an existing D64 on the card, you can create a new one as follows: OPEN 1,10,15,"C:NEWFILE.D64=OLDFILE.D64" (this appears to take quite some time and the LED can remain lit afterwards - not sure why) PRINT#1,"CD:NEWFILE.D64" PRINT#1,"N:DISK NAME,ID"...

Yep, it looks like a device to duplicate tapes. The two outputs probably are meant to be connected to standalone tape recorders, mic or line in in case you don't have access to two C2N's. You should be able to connect it to a PC or so and listen if you hear the data pulses from the tape. Kind of han...

Yeah, sorry. I have received all (?) the vital files from RoboNES. His hosting expired pretty soon after the compo ended and I was not ready to take over the contract. I am still on track to set up a new site later this year. Ideally it should already have been done, but spending on average 11 hours...

Actually I can name two people who work directly on a real VIC-20. One would be Jeff and another would be an Italian guy who communicates through e-mail rather than forum posts.

Yes, the TS 2068 (48K RAM) is the closest match to a ZX Spectrum 48K. I think you can load an emulator onto it to run most Speccy software. The 2068 was advertised as having 72K; 48K RAM + 24K ROM. It would be like saying the unexpanded VIC-20 has 25K, expandable up to 60K. To add to the confusion t...

I'd first expect to see a ?LOAD ERROR. It assumes the loading went far enough that you got a program into the computer. If the alignment is really bad, once you get to the cassette buffer (FOUND program) it can bail out with ?OUT OF MEMORY, which I think has to do with the buffer gets full of garba...

Would the cropped image of a former Playboy model be more suitable for a guy than a female cartoon character? :P

(By the way, that "Lenna" image was once generated with ppm2vic)

Are you sure you don't get ?OUT OF MEMORY error? I can't recall ever seeing ?OUT OF DATA when a load fails. To my knowledge there is no alignment program running on the VIC-20. There were some on the C64, but it requires a factory recorded tape that is perfectly aligned. To record this tape yourself...

By the way, I found two programs here: Phoneme Editor and Phoneme Speak. Those supposedly require "some hardware" at $9800. Could they be compatible with the Adman/Chatterbox series of speech cartridges?

What kind of information would you be looking for? Memory maps, chip documentation, Basic documentation, file formats and so on. I'm afraid there is no common magic way to write software. Which "other machines" do you have experience of? What consists of a more complex program? Diddl's adv...
