It should be easy to build one with a Pico or Arduino. I built one using 
the parallel port on my Osborne 1 CP/M box. It was very disappointing when 
the i386 came out and made tweaking the hardware a PITA.

I'd go that way too since the Z80 was what I worked with, along with 
8080s, 8085s and Intel uCs. 6502s and 680Xs seemed a little strange to me.

That will be interesting. I read an article last week that Raspberries are 
not affected by the tariffs. However I believe Espressif will be. The 
ESP32 has been very popular since it has WiFi and BLE out of the box, is 
cheap, and performs well. Elegoo is also Chinese and is a source of 
Arduino clones. SunFounder is also Chinese. Those two are hobbyist 
oriented but the ESP32 is used in a lot of commercial applications.

I don't know about STMicro.  This may do good things for Microchip.

They may be communists but they're no dummies; Vietnam is talking about 
dropping all tariffs on US goods.
