Denial

Having received my PAL JiffyDOS ROM from retrorewind and finding I needed to fit a turned-pin socket, I went the whole 9 yards and re-capped my Vic-20, while I had the soldering iron out. Video quality improved slightly and JiffyDOS works a treat. When paired with an SD2IEC, it loads games blazingly...

Anyway, those are only limitations if you go by the respective data sheets (and you missed out on the multi-colour capability of VIC-I, BTW) - both computers have demonstrated their video chips are much more flexible than that: see Ultraviolet on ZX Spectrum, FLInale on VIC-20. I own a Bytedelight ...

Thank you.

I'll check and upload a photo.

My C64 was bought from the same seller as my recent Vic-20 purchase. However, the 64 came fitted with a switch-less kernal switcher which starts the C64 in JiffyDOS, but changes to the standard kernal if powered on with the Restore key held down. I purchased the Vic-20 JiffyDOS kernal overlay images...

I've owned a MiSTer FPGA since a little before COVID hit and the ensuing chip famine. There's a stable Vic-20 core for this.

Wouldn't this rely on an FPGA implementation of the VIC chip?

I don't know enough about the MiSTer's many cores; I just enjoy them.

The ZX Spectrum has a display resolution of 256 x 192 pixels. or 24 character rows, by 32 columns, with only a single background and foreground colour per 8x8 character square. As with the Vic-20, if you moved a character smoothly to an adjacent grid, there was noticeable colour clash. It's what the...

I don't remember owning Pixel Productions Harvester when I still owned my original Vic-20 back in 1982/83 but I must've played it, as I re-wrote it entirely from memory for the ZX Spectrum. I sent my Speccy conversion in to Sinclair User magazine, who published it in their December 1986 type-in sect...

The Vic-20 was my second computer back in the day. I started my voyage into computing with a 1K ZX81 (for which I promptly bought a 64K Memotech RAM expansion; which absolutely NOTHING took advantage of), before deciding I needed a colour computer to plug-into into my (even then) ancient Black and W...

Updated FE3 firmware. Now displays v1.8p RENumbered the Utilities menu of the Software Collection and successfully added the wAx2 toolkit (running it from a .prg file I added to a .d64 image), as the first menu option in the Utilities menu. I've yet to work out how to load the CRT image of wAx2, whi...

@srowe The REN function works great. Thank you for adding it. “REN start, step” renumbers just as I’d expect. It doesn’t matter to me that it doesn’t handle GOTO/GOSUBs, just creating space to insert more entries into the LOADER files is enough. Incidentally, the firmware revision, shown top-right, ...

A nice RENUM command may come in useful, though I guess there’d already be a separate program/routine for this already, which I can add into the program loader, assuming I can ever create a working one… :roll: I've released a new version, 1.8, which has a REN command in the wedge. This can be used ...

[Edit] You also find your program is already in this collection https://www.sleepingelephant.com/ipw-web/bulletin/bb/viewtopic.php?t=9616 Awesome collection. I’m using the loader from this collection to learn the structure of LOADERs. I was trying to get Avenger working. The loader in this collecti...

Hi Simon I really appreciate the work you are putting in, to keep the FE3 relevant. Does the linked zip file contain the latest release (1.7) of the FE3 firmware? Edit: NVM. Downloaded it and flashed it to check. v1.7p (I renamed the PAL binary). I swear, I downloaded this yesterday and ended up wit...

Nope.

I simply CANNOT create a working loader for the FE3.

I’ll just wait until my PU+2 arrives after the holiday break and use that instead.

At least I have a software-selectable RAM pack until the modern cart arrives.

¯\_(ツ)_/¯

Oh, there we go… I just answered my own query on the SCRATCH command. @SCRATCH:LOADER works and removes the LOADER file from the root of the SD Card. No card swapping required. Why I thought I’d need to be implicit and specify the drive number, I don’t know… This was on the back of discovering that ...
