The main board should include a large enough array of bidirectional

DEC DSSI, DEC RX01/02, DG6030, and so on, to give a starting point.

Hmmm. rather than re-inventing the wheel, as we usually do, . . .
. . . It says "IBM", "5160" on the back panel label, although there were plenty of generic second sources.
The updated "5170" version of it could be more easily set up even for USB.

:-) But the main goal that was mentioned is device emulation, which existing products generally don't do. I see the idea as a generalized form of David Gesswein's MFM emulator, which is primarily a device emulator but is also capable of reading and writing devices to capture everything that's on them.

The puzzle is how to make it do, say, 2311 emulation suitable to talk to an IBM/360, 1311 emulation for the decimal IBM 1620, or 844 emulation for a CDC 6600 -- to mention just a few of the more exotic cases.

You are absolutely right.
I apologize for my error.

My mindset is/was still stuck in the disk format conversion realm, of trying to get information (hopefully information in the form of files, not just data as track images) from alien media.
And, more often than not, unidirectionally.

I wasn't even thinking about the hardware emulation aspect, which is, in itself, fascinating.
