View Full Version : URGENT: round 9-pin serial mouse or adapter?

August 7th, 2006, 01:31 AM
My mom's old business computer's (486dx i believe) mouse is on the fritz and I haven't been able to find anything online to replace it. When I google 9-pin serial mouse all i get is the trapezoidal (d-type?) serial port.

here is a picture of the end of the mouse:


is it even a serial mouse? or something else? the computer is so dang old i don't know what i'm looking at.

my mom is so frustrated she wanted to get a new computer, which means spending over $2000 in new software (she does computer embroidery). i almost flipped when i heard that.

would appreciate any help or pointers.

I'm not the most intelligent member here, but I'll throw in my 2 cents:

Google the manufacturer &/or the model number on the mouse, & if you're lucky, you might be able to find the pinout of the port, & you might (not sure at all) be able to create an adapter for use w/ a standard mouse! (No promises)

If you're going to buy a new computer, Apples are good "All in one" machines.

If you want to take any old Pentium 2 or 3 system & use it, I'd suggest Linux, preferably Ubuntu Linux. This would be the Cheapest - & probably easiest - Solution...

I've never seen a mouse like that! I would think the easiest fix would be to buy an expansion card that either has a serial or PS/2 port, and use a standard mouse.

It is a full-size DIN, not a mini-DIN? I have vague memories of such connectors, maybe dating back to the Wang PC era and alike. I'd like to think it is a video connector, but you can't mistake a mouse for a monitor. A 486DX that has a such type of mouse or anything must be a special brand. Maybe you can see if the computer has a more typical DB9 (or even DB25) serial port and get a serial mouse to it. I believe a few non-IBM 486:s had a PS/2 option too, but it may be more common on early )and more recent) Pentium systems.

It's called a 'Bus Mouse', and they aren't very hard to come by. Just did a quick eBay search, found this (note the connector):

Alternately, the bus mouse usually runs from it's own interface card, which can be removed (or disabled) to use a serial mouse instead. This may be necessary if it turns out that the card is bad and not the mouse itself.

6 of them! That would be enough for the next 90 years :D

Yep, "bus mouse" is what I thought when I saw the pic. Yep, yep, separate card, etc. etc.

Me too, but I didn't find any conclusive evidence and focused on a full-sized connector. Apart from video editing equipment, I'm quite sure I've seen those on computer stuff (at least the Wang, but it is many years ago).

I think I have ps/2--bus mouse converter... in my graveyard... these are not really that uncommon, are they?;)

They would be extemely rare and perhaps you're mistaking a serial mouse for a bus mouse.

I only have one amid the multitude in my collection.
I also have a PC card in an Amiga 2000 which has a connector for one.

In the early Winblows you almost had to have a bus-mouse in order to use it. IIRC the serial PC mouse came later. And of course the PS/2 mouse later still when IBM introduced the 8580 and the other PS/2 models.

Adapters won't work on a BUS card since the mice operate differently, I think the BUS mouse sends the data to the card to decipher movement while a ps/2 and serial mouse do some signal converting in the mouse itself.

Old ATI ISA video cards used to have BUS mice ports built in.

Ya that's a bus mouse. You see them from time to time on ebay.
