[RESOLVED] Sidekick20 black screen
Hello, I have built a Sidekick64 based on a Rasberry Pi3 A+. I have tested it working flawlessly with a C64 and a Plus4. For an unknown reason, it will not work on the two VIC20 machines I own. What I get is a proper Sidekick20 image loading on the oled display but the screen of my TV stays black (n...

Re: Convertir Vic20 prg files to BIN
Hi srowe, It is a fail unfortunately. I concatenated 6000 and a000 then another file with a000 first and 6000. I burned the 27c128 and tested both files but none is working. The VIC20 will boot to the prompt each time. The 74LS00 is fine and tested with the programmer. Those 6000 and a000 files are ...

Re: Convertir Vic20 prg files to BIN
OK, if you look carefully you can see there's a bridge between pads for BLK3 in Block_L and one on the BLK5 pads in Block_H. So you want to create a single image from the one that resides at $6000 followed by the the one at $A000. You'll also have to populate the socket, I'm guessing it needs a 74L...

Re: Convertir Vic20 prg files to BIN
You can't just concatenate them, there's a 'hole' between them. You'll need two separate EPROMs, unless you add some decode logic to map accesses to BLK3 and BLK5 to consecutive addresses. Hi srowe, yes the 27c128 eprom is to be used with the pcb in picture. It is the project available here on Deni...

Re: Convertir Vic20 prg files to BIN
the 8k cart is working good :D I edited the prg and deleted the first 2 bytes. That did the trick. Now my question is how to handle the two separate prg's for 16k carts (6000 and a000 hex)? I have deleted the first 2 bytes of each then I assume I should concatenate the two but in which order? a000 f...

Convertir Vic20 prg files to BIN
Hi guys,
Does anyone know exactly how to convert prg images of VIC-20 carts into bin files to be burned to eproms? I have some PCB's for DIY Vic20 carts and would like to burn the 27c64 with up to 8k cart images for testing.

Re: Cartridge designs released - Eagle PCBs
Hi guys, I have ordered and finally received the pcb for 8k and 16k cartridges :-). Although I am good in soldering I would like to ask some help for the programming part. I will start with the 8K board and a 27C64. My question is : - does the binary needs to be 8k or is this the maximum? - which fi...

Re: VIC-20 and key repeat function ??
Hi Stormcrow,
Many thanks for this little tutorial on how to enable repeated keystrokes for all keys! I will for sure test it
And yes of course the cursor keys have also the repeat function enabled. My memory is failing again and again
Thanks!

Re: VIC-20 and key repeat function ??
Ok so by default this was not set up on a VIC-20? I do recall of course this working on a C64 but had a doubt for the VIC20
EDIT : I found! Actually the keystroke repeat works for the spacebar only for both C64 and VIC . My memory is failing

VIC-20 and key repeat function ??
Hi guys,
A fairly simple question. I cannot recall if the VIC-20 will repeat the key pressed if I keep my finger on it My VIC20 does not do that and wondering if this is normal.
If not then what could be the problem? All keys are working perfectly when pressing them.
Thanks
Rick
