Soarer's Converter IBM Model F XT issues

[daniel_j]

Hi there,
I have used a pro micro clone to create a Soarer's Converter, confirmed the wiring works correctly with a 5 DIN Model M, however my Model F XT is not working.
I get this output with hid_listen:

Code: Select all

Waiting for new device:..
Listening:
wEE 

remaining: FFFC


Keyboard ID: 0000
Code Set: 1
Mode: PC/XT


r00 +00 
r80 -00 

A couple of keys create the r80 -/+00 codes.
Occasionally on plugin I get this:

Code: Select all

rFF R05 rAA r3B +3A d3A r76 +73 d73 r3D +3C d3C r00 +00 r3F +3E d3E r41 +40 d40 r43 +42 d42 r00 r3C +3B d3B r00 r3E +3D d3D r00 r40 +3F d3F r42 +41 d41 r44 +43 d43 r38 +E2 dE2 rFF rFF

I've confirmed the cable is fine internally with a multimeter.
Where should I look to next to further debug this?
