I'm going to join the "building an expansion board" to add a better power and TTL switch-on/off interface. 

How's everyone's working so far?

My hardware works great, working on the software.

This is version 2 -- includes a Pico and an SD card and will let you upload PTP files.  Can auto-switch over to the TTY mode and the attached wire connects to the reset line.

The buttons are standard tape-deck buttons + RESET + MENU

I didn't have a USB reader at the time so I bodged in an SD card adapter. Looks funky but it works.

Jeremy's build looks powerful!


Nils, I’ll soon have both the small and large daughter-boards ready, since I feel that shipping just a small one isn’t cost-effective.
