IBM XT 5160 - Error 301

[modem7]

Hi again! Some (semi) closure - received the XT-to-PS2 adapter from Tinkerboy...and it works fine! So this XT looks in great health and the issue was with the USB4VC all along. I reported it to the creator and hopefully I can help him improve the firmware.

Thank you for the update. Readers now know of the (current) incompatibility.
