Old macintosh ED Mouse Ball
- Thread starter Pete16

IIRC the original Mac 128, 512 and Plus mice used a 1" (25.4mm) rubber covered steel mouse ball.
Later types (most Apple ADB) and other manufacturers (mostly a logitech mechanism inside) used a 7/8" (22.23mm) (Mitsumi), or a 21.9mm (Logitech).
This makes sourcing the original 1" mouse ball a little difficult.
The original service part number was 699-8001, replaced by 922-0998.
However, the same 25.4mm mouse ball was still present in the early Mitsumi ADB 'angular' Mouse. There was also an Alps version of this mouse (but the ball size eludes me).
And it seems that 'WeLoveMacs' still has them:

For future reference:
I did find a company online that claims to make their own but no longer show stock of the 1" ball.

The angular ADB Mouse was revised to the smaller ball with the "ADB Mouse II" often referred to as the 'tear-drop' or 'Ergo' mouse. You'll still need the original retainer ring with three wings for your Mac 128/512/Plus mouse.
The ADB Mouse II had two different serial number prefixes
"M" prefix (Mitsumi) used a 22.23mm steel/rubber coated ball
"L" prefix (Logitech) used a 21.9mm black lightweight ball

Thanks, @CooperBox
Just thought I'd add a word about the Allps version of the angular ADB mouse, since I stumbled upon this:
"A certain design of the Apple Desktop Bus (ADB) Low Power
Mouse (part number 661-0479) is susceptible to electrostatic
discharge (ESD) damage and failure. This mouse does not have
adequate shielding for safely discharging static electricity, which
causes the charge to hit the control board and disable the
Application Specific Integrated Circuit (ASIC) controller. There is
no electrical shock hazard to customers and there is no potential
damage to the system or keyboard. The symptom of this type of
damaged mouse is a complete loss of horizontal and/or vertical
cursor movement.
How to Identify an Affected Mouse
An affected mouse can be identified by its place of manufacture
and serial number. Look for:
1) "Made in the USA" and
2) An 11-digit serial ranging from AP038xxxxxx through
AP103xxxxxx (inclusive)
These mice, which were bundled with systems shipped
September 1990 through January 1991, are still under warranty.
However, we created a special product return program to quickly
eliminate the problem in the installed base. Since these mice were
removed from Finished Goods stock and were never stocked by
Service, the product return program addresses customer returns
only.
That would be this one:
