My information comes from using the IEEE Flash! from Skyles, but there
are many similarities between them.

The first switch is an on/off switch.  When the switch is off, the
entire interface board is disabled.  You must turn it on to access the
IEEE bus at all.  On the C64, this controls whether the new Kernal ROM
is switched in, but the C128 adds its own ROM, so this switch may have
no effect in C128 mode.

The other three switches change which references to drive numbers are
channelled through the serial bus, and which are channelled through the
IEEE bus.  Such as:

Switch 2:  ON, device 8 is IEEE,  OFF, device 8 is SERIAL.
Switch 3:  ON, devices 9 and 10 are IEEE,  OFF, devices 9 and 10 are SERIAL.
Switch 4:  On, device 4 is IEEE,  OFF, device 4 is SERIAL.  (Printer!)

I may have some of these switches in the wrong order, but a little
experimenting should sort it out.  I believe the interface board causes
references above device 12 to ALWAYS be on the IEEE bus, but that
doesn't happen very often anyway.

The clip is required in order to swap the internal ROM with the C64 ROM.
It does not affect C128 usage as far as I know, since that ROM is
already in the machine at all times.  It also prevents you from easily
unplugging the thing, which is annoying.

My IEEE Flash! came with no software, just the board and instructions.
