pico6502 works. An RP2350 in the 6502 socket, running Galaxians and Chess on a BBC Model B and BASIC on an Apple 1 Replica. The PIO timing bug that was stalling execution is fixed and the bus cycles are clean. Next: custom BBC drivers for the FDC, hard disk, Econet and sideways RAM/ROM. What it is: a drop-in CPU replacement built on the picoZ80 framework, so it brings the same ICE debug shell with it — you can halt the machine, inspect memory and single-step from a serial console while the host is running. What was wrong: the 6502 has tighter bus timing than the Z80, and the PIO state machines driving PHI2, R/W and the data bus were a few nanoseconds out of phase with the host. Reads worked, execution didn't. The fourth image is the LA5016 capture that finally showed it, with PHI0/PHI1/PHI2, SYNC, R/W and the bus lines side by side. What's next: the BBC side gets interesting once the CPU is trustworthy. Because the RP2350 sits between the software and the hardware it can present peripherals the machine never had, so the plan is virtual drivers for the 8271/1770 FDC, a hard disk, Econet and sideways RAM/ROM, then on to the Master 128 with its 65C12.

After 4 years of effort, I'm happy to announce that one of the final secrets of the PS2 has been broken wide open! It's been a long process of decapping, optical dumping, and now at last a software solution. Thank you Libby for finding the exploit from our dirty optical dumps!

this is the longest breadboard jumper i've made so far

The idea behind DMA is straightforward: instead of having the CPU repeatedly move data between a peripheral and memory, configure the DMA hardware to do the transfers for you. The difficult part is figuring out how all the pieces fit together. Learn more! bit.ly/4dzXk7N

I did a thing. First Article sample received. So many of us have memories of the 555-timer studying electrical engineering and PCBs, after seeing plushy oscilloscopes and plushy coaxial cables, I thought to myself why not a plushy 555. 😁

There's a strange irony in using a clanker for garden planning.

First 10 prototypes of the "lowest cost game system" are ready and will be available for purchase by developers soon! Features a 32-bit RISC-V core at 48Mhz!
