Denial

Hello everyone! I've been a member on this forum for more than 15 years by now, mostly in a 'stalking' mode and following with amazement all those reverse-engineering topics over the years. Don't ask why, but about a year ago I have added VIC20 emulation to my existing Commodore plus/4 (and C64) emu...

Thanks for the elaborate reply and the suggestions! I must admit I haven't really delved myself into the inner workings of VICMON prior, just fired up a disassembler and recompiled for a new base address. I'm primarily a TED person myself, so that functionality would have been just proper for me, I ...

Thanks, I managed to load it up on my VIC. I'm sure it's my fault but the commands shown in the video do not appear to work, I am getting a ?SYNTAX ERROR.

Perhaps you could just record them as a plain mono WAV using any tape device and upload them here. I had some success recovering old tapes using this method (after applying some signal processing in Audacity). I do have an MTAP cable but it requires an old-school parallel port which is kinda hard to...

Alas, I possess a VIC20 with only a 3 kB RAM Expansion. I have been looking at options how to use an assembler for this machine with so little RAM but found that 1) Tinymon has no assembler 2) Minimon would be great but is cart-only and was not released as a standalone PRG AFAIK 3) VICMON kinda work...

Excellent find, how about dumping the original tape images as well?

Small update: it was indeed the BASIC ROM, turned out this friend of mine had a replacement chip after all. And thanks for the tip, it will be socketed

Thanks! A local friend of mine offered me help although the replacement ROM might be an issue for him, so cheers for the link!

Aaaand.... it works! Yay... so it's the ROM then. Alas, I have double checked and only the KERNAL (901486-07) seems to be socketed, the BASIC ROM (901486-01) - that is the likely culprit here - is soldered :( I fired up my Ebay account to check for a replacement and was shocked how expensive these a...

That's a very good idea! I have a Cosmic Cruncher cart somewhere in the attic... gonna go ahead and dig it up... let you know how it went. Faulty ROM would be the "best" option as that's the only socketed IC

Hi all, it's been a while since I posted on this forum. I have dusted off my good old VIC20 today that used to be in working condition the last time I fiddled with it (around 2017 I believe). To my horror it no longer boots up properly, looks like some part of the circuitry or one of the IC's went b...

Wonderful idea! I love databases :-) When citing examples, let's not forget the Commodore plus/4 database here: http://plus4.emucamp.com Some might think the plus/4 had no software written for it, now we are exceeding 5000 pieces. Something like that for the VIC-20 would be fantastic (GameBase is no...

My VIC has arrived in the post today Just playing around with it now a little. There's a 3K RAM expansion and a Cosmic Cruncher game cartridge with it (plus 2 books).

The noise channel sounds really weird!

Heh yeah, it's "me" Thanks for the warm welcome.

How come not compatible? The most important peripherals can be (re)used for the C16: C1541, monitor, joystick (with a converter cable), datasette (again, with a converter cable).

Anyway I am getting the VIC for 20 euros... nomen ist omen If all goes well with a cartridge, too
