I always thought Acorn had specified the Teletext Adapter
as the last device on the 1MHz bus, and consequently it
only has one connector.  The Acorn Winchester Disc 
definitely has two, for daisy chaining as does the FileStore
E20 which is essentially the same as the Acorn Winchester
disc except it's a SCSI drive inside so there's no ST506
controller board, just the host adapter and the disc.

As for third party devices, my Technomatic Winchester
has 1MHz bus in and outs, but my Opus Challenger
only has the single 1MHz connector, so maybe the
Technomatic is unusual in this regard.

Dunno about the Music 500, it's buried somewhere.
I haven't seen it for years and I've never even plugged
it in or switched it on.  Shame on me, etc. etc.!

It's going to be a while till I get some pictures done of
the Digistore, but there will be a sneak preview of all
the items which arrived with it just before Christmas,
probably Sunday, as soon as I get round to the final
pre-Christmas BeebMaster update.  I'm still wading
through the remaining 130 Domesday screenshots!

Best wishes,




Ian

In my experience, every company which made devices
which sat on the 1MHz bus stated that their's should
be the last device.

I've yet to see a 1MHz bus device with in and out connectors,
or removable terminations.

My 1MHz bus is double-terminated: hard disk, and EPROM programmer.
