plus 4 kernel

I have been wondering about the plus 4 kernel. The same kernel is used in both the plus 4 and the commodore 16. Seeing as they have different configurations with memory size and also the extra roms in the plus 4 is there a routine in the kernel that determines which machine it is fitted into or are ...

Re: is this plunger uncommon?

I found an article on an Australian website https://forums.overclockers.com.au/threads/vic-20-restoration.1220403/ from earlier this year. The guy had the same keyboard and same problem with broken key stem. I might try his repair. I was hoping someone might say I have a spare I can help you with bu...

Re: is this plunger uncommon?

Hi Overdoc, Thanks for your reply. I have attached pics for reference. I included a pic of the pcb as well because I am wondering if I had a euro style key and stem and spring would it work with this keyboard? 20171207_230044.jpg 20171207_230717.jpg 20171207_230744.jpg 20171207_231027.jpg 20171207_2...

Re: Vic Computing Magazine?

I don't like to keep hard copies of anything these days, especially magazines. But no one had a pdf online for this one yet so I didn't want to miss the opportunity of getting it to complete the set of issues. If someone else had bought it perhaps they wouldn't have uploaded it, so I did set a prett...

HES Synthesound

I have been playing with the Synthesound cartridge and found a peculiarity with it and I am not sure if it is the normal behaviour or there is a fault with the cartridge. When I first start, if I disable all but one voice I can play one voice. But if I start with more than one voice I cannot turn th...

Re: One VIC-20 Release for Zoo 2017 ...

Nice. I found an interesting read at http://linusakesson.net/scene/a-mind-is-born/index.php about a 64 demo explaining the code. I wonder if anyone has done similar for a VIC20 demo?

Re: is this plunger uncommon?

Yes, thanks, mine does have the square O key and the replacement key I got from the guy was from a pet style keyboard which makes me wonder why he could not send the correct plunger.
Is it possible some pet style keyboards used c64 style plungers?

is this plunger uncommon?

I bought another vic that needed fixing. It needed a new vic chip and a bit of a clean but it was also missing the 9 key. Lucky for me I thought a guy was selling keys for keyboards on ebay.au Unfortunately the plunger he supplied was incorrect and he claimed in all his time playing with commodores ...

Do you have the maintenance manual? There is a lot of information on how to do available but I didn't see any that didn't need an alignment disk of some kind. https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0ahUKEwiyrr_r8pHXAhVHwLwKHWexCiAQFgguMAE&u...

Re: cbm prg studio

OK so I figured out what I did wrong. The BYTE instruction was loading my custom character data into 7168-7175 at the start but then was copied over by the CHAR_COPY routine. Once I changed the starting address CHAROM_START and CHARAM_START to start after the loaded custom character data it worked.

Hi, I am copying the character set to top of ram and modifying. I just want to know an easier way of loading the modified character data into memory. Thought I could do that with the byte statement but it doesn't appear to work. However if as you can see I do a series of loads and stores the data is...

cbm prg studio

Can someone explain how to load a list of bytes into memory using assembly in cbm prg studio.
I tried *=$1C00
BYTE 126,90,255,189...
I copied the code generated by the SYS call generator tool but the bytes don't load into the location specified when it is run in the emulator.
