I think this is for a Commodore 64, I got it from a friend of mine who had it in his loft many years ago now. It says "Xyllyx" and "CBM 64 Comms Pack".
I'm guessing from that it is a communications device of some sort.
Second question is does anyone want it?
Can I ask someone about this doug

I will take it.
Sure you can. I can't find out anything online at the moment.
From what i remember its an RS-232 device...
Great stuff for giving it away fella...
Thanks, I have Emailed this link to someone who may know, lets see what it is!
Be interesting to know what it is, and to know it's going to somewhere where it may get used. I have a C64 but no power supply (it may not even work) so I can't do anything with itÂ

it will be donated to a good use, thats for sure, we still don't know exactly what make it is and its origin, but we will find out soon.
You c64- have you considered ebaying it as a raspberry pi project? my video has had 11000 hits, there must be interest in making one from a 'dead' c64
Also the sid chip is worth £15 if working!
I'm sure the C64 worked before it was left in the garage because I'd tried it on a powerpack I had with a boxed one which I sold. Let me know where to send the mystery object sometime and I will get it to you.
PMed
:D
As long as I get to know if it does anything, what that is lol.
Its some sort of modem, but I have no definitive on it yet, but we will find out what it does.Â
Well, while clearing my garage today I found 2 more of these both with manuals and leads included in the bags. Obviously not so rare lol.
Will post a pic of them soon.
If someone tells you they have a one of a kind item, have Doug search his garage first
