@Managarm
I was interested in this until I dug out some old Eyetech literature. This indicates that the BMON/SMON unit is in fact a monitor switcher and NOT a scandoubler or SD/FF.
Whoever wins this auction may be disappointed to find they still need an SD or SD/FF to supply this unit. I may be wrong, but the Eyetech descriptions put me off this one.
Cheers,
