I wonder if it could be some kind of data transfer switch. I have one
similar that I used to transfer signals to my printers. It had a switch on
the front that would go to my laser printer and to my colour printer. It had
an A and a B and a I/O. All three had female 8 point conectors on the back.

Subject: Strange external device?

Hi everyone.

I just rearranged my NuBus-cards/HDDs/floppy-drives collection for
proper storage, when I came across a strange little box:

It's white, made of metal. At the back it sports 3 ports. One labelled
'A' which is a Mini-DIN8 connector (fits a Macintosh serial cable).
The other two are labelled 'B'. One of them is the same Mini-DIN8
connector as with 'A', the other is a DB-25 connector.
Of course there is also a socket for the power supply adaptor.

On the front is says 'MacAccess'. No more, no less. I've tried
Googling it, but nothing turned up. Does anyone here know what it is?
I'm eager to find out!


Greetings,

Eelco.
