Flashing to the tinkerboy is pretty easy, just need to ground the reset pin which is clearly marked on the pcb, after that it's just DFU.
To get to the reset pin you need to remove the casement which is two plastic shells held together with a few friction pins.
Comes apart and goes back together with no damaging or signs of entry
Reset pin resolves all the XT related issues so we can add these to the list of working boards
Z150 XT - Part Number: 92-803
BTC-5161 - Part number: BTC5339 (Not to be confused with BTC-53 series keyboards)
Sanyo N860-2905
Curious as to why the Reset was needed on the AT/XT switchable boards in XT mode, seems like they were outputting XT scancodes but not being detected as XT?
The Sanyo board also functioned with a Soarers converter without Reset pin somehow, maybe just lucky?
The Z150 AT is now correctly detected as AT and hid_listen shows scan codes which appear to be correct for the keys being pressed, but nothings makes it to the system.
Internal beeper is working properly including with repeat/disable.
Lock lights will change with the system, but do not initialize to the right state.
