Re: Final Expansion 3 NG

Re: Final Expansion 3 NG

I've started writing a completely new document to explain the FE3 architecture. It's unfinished but hopefully it contains the sort of information you were looking for https://eden.mose.org.uk/download/FE3%2 ... 0Guide.pdf It's entirely derived from my study of the schematic and the firmware, and wr...

Re: WRITE NOW! cartridge image problem

That's the trick! There is indeed stuff stored in IO memory ($9800 - $9BFF). If I load a dump of that into Vice along with the image from $A000 - $BFFF it works as it should. Thank you, Mike! Attached is the dump from $9800 - $9FFF ("wn dump 2.prg.zip") and "wn-full.prg.zip" cont...

Re: Finally a manual for WRITE NOW!

And for the sake of completeness I have uploaded the keyboard overlay templates to archive.org. Printed on US letter size paper (8.5x11 inches) they fit perfectly on the VIC keyboard.

WRITE NOW! cartridge image problem

I'm having a problem trying to get a good cartridge image for WRITE NOW!. The one that is available at zimmers differs from the actual cartridge image and exhibits several bugs. The image I have dumped from the cartridge will not run when loaded into RAM nor will it run on the FE3 even when protecti...

Finally a manual for WRITE NOW!

I finally got my hands on the manual for the WRITE NOW! word processor for the VIC. Since I have never been able to find a scanned version online I went ahead and scanned it and uploaded it to archive.org. You can find it at: https://archive.org/details/write-now-vic-20 (mod: thread moved from Gener...

Re: Green on Black 2 (Santa Paravia, Dungeon)

Thank you for that. Don't know why I didn't think of doing that for the docs since I hated having to pull up the old magazine pdf to figure stuff out.

Re: Black Screen VIC-20, and more issues.

That’s impressive especially for hand cut. I would have tried to get it cut on my Cricut machine. But then again I am stupid dangerous with a knife. :oops:

Re: Late (not actually) to the FE3 party. Operational Queries.

If you are sure your cartridge file is loading you might want to check whether it has the $A000 address in the first two bytes. If those two bytes end up at the beginning of your loaded block in ram your cart can't run. It depends on whether you are loading the file to a specified address or loading...
