Looks like the DECromancer image `BBB_deb11.9_mfm_v4.31_2024-10-23.img` is working on a BBGW (v1.0) here, too. The mfm_emu board itself is a DECromancer rev C, serial number 007.

Host system is a Tektronix 6130, and the BBGW is on the network directly through a TP-Link "UE306(US) VER:1.6" USB 3.0 Gigabit Ethernet dongle.
