Good day in the mailbox... the Willy Wonka CPU boards have landed on the bench. CPU is the 3K RAM half of the Willy Wonka family for the VIC-20. It drops 3K of RAM into the BLK0 region ($0400–$0FFF), the gap the stock machine leaves wide open. Address decoding
Good day in the mailbox... the Willy Wonka CR boards have landed on the bench. CR is the color RAM half of the Willy Wonka family for the VIC-20. It carries 16 pages of color RAM, which is what makes FLI-style raster graphics possible on a machine that was never
Every hardware project eventually teaches you the same lesson: the debug interface you bolted on as an afterthought is never quite right. The test points are in the wrong place, the UART is on a 0.1" header that shares space with a stray decoupling cap, and the JTAG
Not every update needs to be flashy. Sometimes the best improvements are the ones that make everything else work more smoothly. This revision focuses on the infrastructure that keeps NeoCore running reliably and makes development life considerably less painful. Housekeeping Gets a new brain The change is a new GreenPAK
The latest PCB revision of the Willy Wonka is back from the fab and assembled. Good news — it works. Most of the time on this round went into getting the GreenPAK configuration sorted out. The address decoding and page select logic is now pretty much locked down. There were a
