The C64 Maxi

Unread post by Locutus73 »

Did anyone try to use a The C64 Maxi

as a MiSTer case/keyboard/USB hub replacing its ARM system board with a DE10-Nano?

Regards.

Pretty neat, I didn't even know the C64 Maxi existed... and not available in NA. :( Sounds like they intend to ship to NA sometime this year.

I also saw video on 8Bit Guy channel that some Guy used regular C64 or Vic with Pi and some keyboard to USB board. I also have Maxi, neat device but not really handles well music roms made for dual SID. Mister core is lot better. But one thing could be added or maybe I am not getting it properly... I mean disk handling since to Play game after mount I must enter the command to run game from disk and not having know layout classic PC keyboard is useless. Pet core get this OK, but C64 not, good option will be adding option to get normal characters from PC keyboard for example (") and option to disable this option for normal C64 mapping.

I think on a standard US keyboard to get "*" on C64 it's the 2/@ key and ] key, or if you are using Jiffydos just press shift+esc. I'm not in front of my Mister or I would check, but my muscle memory seems to think that is correct.

I bought one, and soldered a socket to a USB cable (Würth WR-WTB, 2 mm pitch, https://www.mouser.ch/ProductDetail/Wur ... yVEQ%3D%3D), I guess this is not the type that was originally used, but it fits).
This way, you can plug the connector from the keyboard to the cable, and keep The C64 Maxi in working order (although I am not sure why I want to do that)

If you like, I can try to upload the keyboard definition and the joystick button definition.

You can also use it as windows PC keyboard, but this is not much fun, as, for example, the alt, cursor left and up keys are missing.
Also, having it as second keyboard is not fun because, AFAIK standard Windows keyboard layout handling is not as flexible as the MiSTer: you cannot have different key-maps for different keyboards.

Could you upload the keyboard/joystick definitions when you get a moment? I have a c64 maxi that I’d like to use with my setup, thanks! :)

Sorry, I missed your posts asking for the map.
One wonders why I did not just post them right then and there, when I mentioned them...

You find the keyboard map and a map for "The C64 Joystick" attached.
It is updated to work with the current C64 core.

The arrow left would work in the original mapping, but I remapped the arrow left to F12 for more convenient OSD access.

The Menu key of the C64 Joystick also opens OSD, so if you use that, you could modify the key map to get the left-arror key back:

Open the kbd map with a hex-editor, and change (key code) location 0x29 from 0x58 to 0x00 (0x58 is key code for F12, 0x00 means no remapping).

To get it to work with older cores:
Set key code location 0x0C to 0x43
Set key code location 0x28 to 0x2B

Just a little question: Where did you find the original codes? for example the RESTORE key 2 digit hex code (or the RUN/STOP), where can I find the original codes? do you have a table? thanks.

Hi just to contribute:
In the keyboard the keys "=" and "+" were swapped. I edited the hex file and it works (little headache finding the positions :D )
I just end with one issue : when I press shift+8 or shift+9 the symbols are the ones to the key on the right.

Thanks for this tweak. Did you ever sort out those shift 8/9 issues? I also noticed that in the core OSD I can't go UP which is important in navigating my LONG lists of C64 games :(
Cheers.
