Blinky running on the 1802. Best proof I have a genuine one.

Probably because the age counter keeps ticking up relentlessly I became nostalgic to build a retro computer based around the very first CPU that introduced me to (and started my career in) computers, the CDP1802 (which is still in production at Renesas!). That must be about 45 years ago...
Just sent the first PCB designs to JLCPCB. With some luck the adventure can start again somewhere next week.
Also, wouldn't know how to achieve this without #kicad

My CDP1802-equivalent RTL core can run at 166 Mhz in an XCKU5P Kintex Ultrascale+ FPGA (-1 speed grade). Given that my core takes exactly 1/8 as many clocks per instruction as a real CDP1802, this means that it will run at the equivalent speed of a 1.33 GHz CDP1802.
The real CDP1802 typically ran at 2.0 to 3.2 MHz.
