Picked up a bunch of Commodore 64 stuff tonight, and inside was this SP0256A-AL2! Guy told me him and his brother ordered a kit from a magazine back in the day and assembled it. Time to figure out how to make it talk #commodore64 #retrocomputing

Ham radio operator, retro computer nerd, electrical engineer. I have way too many unfinished projects.

And this really neat numpad which includes a board the sits between the keyboard and the C64 motherboard to make it work with everything! #commodore64 #retrocomputing
Some more #c64 progress on the #analoguepocket. I have verified that the cartridge to C64 interface is working as I can read and write values to the GeoRAM, whereas in the second image the register is just displaying garbage. Task this weekend is to try to get something loaded on the C64 from the pocket. I have a conceptual understanding on how it works, just need to actually implement it now… 🤞 #retrocomputing #retrogaming
It doesn’t look like much, but I’ve started laying the groundwork on adding cartridge support. Stuff is intertwined in the MiSTer so I had to add the REU, cartridge IP, and switch the RAM from blockRAM to the pockets SDRAM. Super glad to see it boot up! #c64 #retrocomputing #analoguepocket
So it's nothing amazing since all the BASIC is doing is writing random values to the SID, but the audio is now working! #analogue #c64 #retrocomputing
Some more progress on the #analogue #c64 core. Finally got the shift key working so I can run some fun BASIC demos! Feels a little hacky but it works #retrocomputing
