Anyone have a Mac Plus mouse?

Hey guys, its been a while Tongue
So, I just won this: http://www.ebay.com/itm/Apple-Macintosh-Plus-1MB-Model-M0001A-/121117229...
It's missing the mouse, so I thought I'd ask and see if anyone had one. If you do, please give me an offer. Thanks Laughing out loud

Off: There was a cool hack presented at 68kmla to connect a USB mouse to the DB9 port.
Maybe worth a shot, until you find the real thing.

Don't have an extra for you, but I just purchased a Desktop Bus Mouse II on eBay the other day for $12.99. Looks like there's an original desktop bus mouse starting at 99 cents (no bids yet) that ends tomorrow (tuesday 6/4) morning - could be worth a shot. cheap enough!

I might. Let me look through my box of early Mac stuff; if I have more than one (I need to resuscitate a 128k in the near future), I'll gladly get it to you. Enjoy your Plus! It's a very nice machine, though it can be picky about SCSI drives sometimes.

You paid $13 for an ADB II mouse ?
I have 8 sitting in the garage ready for the charity shop. And another 4 I kept for my CC, SE and PM5400.

Guess I should have checked here before purchasing my accessories for my Classic II! At least it was free shipping...

I assume any DB9 mouse would work on a Mac Plus? I may have a few PC DB9 mice laying around.

Nope. PC DE9 mice are serial mice; their plugs are also DE9F, which will not mate with the DE9F on the back of the Mac. The 128k-Plus mouse just spat out the quadrature/button signals directly, which were received by the 6522 on the board and decoded in software.

Not according to this:

Looking a mouse for a Mac Plus.

I think any of the early mice from //s, Macs with the DB9 style connection should work.

ADB mice such as that on my Classic 2 are a later shape, and PC serial mice the DB9 connector is the wrong 'gender'.

I do not have one though on my mac plus I use a modified MS-Mouse (see solution 2 below).

Solution 1

You can use some serial MS & PC mouses on the Macintosh with a DB-9 to DIN-8 (or DIN-9) serial cable (and possibly a gender changer depending on the cable), if you can find (or write) the driver.

There is some info on using a serial mouse here:
PC-Mouse on the Mac (the original text)
AND:
Re: Mouse for a Mac Plus...

Solution 2

It is possible to modify many old serial mouses (correct plural for computer mouse) to wire the quadrature encoders and buttons directly to the correct pins, usualy these have a higher resolution than the mouse that originally came with the Macintosh 128K/512K/512Ke/Plus, though this mod usualy works (as long as the mouse has a ball and is not to new (made before 2001) you should be ok to modify it.

I could not find a guide for this and I do not feel like writing one at this time, though it is fairly strait forward.

For the Macintosh Mouse port pin-out see:
