Title: What Model M connection is this?
Post by: Roguemaster8 on Tue, 28 February 2012, 02:03:58

This picture is taken from the back of a Model M 1390120 that was manufactured in January 1987.
I knew the earlier models used AT connections but was wondering if a PS/2 cable from Unicomp would fit and work just as well.

Thanks for the help, I've never owned a Model M before, so my knowledge of them is fairly limited.

SDL. Doesn't say much as both ps2 and at connections used SDL's as there socket.

The one I'm looking at doesn't come with a cable, and researching it I found out it uses an AT cable.
Does this mean I would need to buy an AT cable and then an AT to PS/2 converter to get it to work?

The model number you are looking at seems to be an AT model.

I see, thanks for the link.

Does anyone know of a retailer selling AT cables?

I cannot find any, at the cheap price of model M's in the US wouldn't it be just cheaper to get a ps/2 model?

Wanted the 1390120 for collecting reasons, and also found a cheap sale for one for $15.

Just was checking to see if finding an AT cable was possible. Or if I could interface it some other way.

The 120 should work with either cable, AT or PS2, black or beige. I have never had a 120 but I have had a couple of 131s and I think they are the same.

I am pretty sure that the originals came with a "short" black coiled cable with the large 180 degree DIN connector. That one should work with a DIN-to-PS2 adapter.

Those would be less desirable for someone actually using the board, but I understand that you want the old one for collecting. I might have 2 of those, if I find the extra I would consider selling it to you.

Thanks for all the replies. I would like to start a collection but having fully working models would be nice too.
