I have resumed shipping to the USA.
The Postage / Tariffs / custom charges appear to have settled down to the point where I can semi-accurately predict the cost of postage, before I send the package.

RomWBW Bus kits now available.
All the features of the Pico2 RomWBW kit PLUS
an OLED display emulating a 2 line LCD and a full #RC2014 IO Bus, so you can run RC2014 peripherals. Not that you really need to as you have SD disks, Speech synth, 8 bit LEDs / switches on the front panel. Neo pixel driver. Running emulated Z80 CPM via #ROMWBW from an onboard RP2350
AND it can be directly plugged into a RC2014 backplane.

From now on. All RomWBW kits sold with a Pico will be provided with a PICO2 (Pico1 is still supported , and so is using your own Pico)
Meaning, Ram disks, Fast File Serial and oodles of paged RAM in RomWBW :)

Well, a long day today sorting out the problems SDK2 had caused with the #RC2040 and the increasingly aptly named FFS (Fast File Serial) File transfer from CPM to the RC2040
SDK2 really didn't like compiling bits of CPM tools. Causing it to crash, randomly only when the code was referenced, but not run. (very long story)
Refactoring sorted, and I'm glad to say, the RC2040 has FFS again.
and just for fun, so does the RomWBW now, as long as you have a Pico2 https://extkits.co.uk/product/pico-romwbw/

Mini Wimshurst generators are now in stock. (but, not not too many of them yet.)
60kV of "static electricity" and one of the best looking high voltage kits I've made. (but I'm heavily bias)
