NeXTSTEP and Plan 9 do not tolerate running mouse at 9600 baud

Solaris and Linux can run the mouse at 9600 baud, but on NeXTSTEP and Plan 9, the pointer will misbehave.

• NeXTSTEP 3.3 (found during development) works at 1200 baud
• Plan 9 (reported by Anthony Sorace) may work at 2400 baud?

if you encounter problems with the mouse pointer moving erratically, try one of these:

• firmware 1.5 with the mouse set to 4800 baud
• firmware 1.5 with the mouse set to 2400 baud
• firmware 1.5 with the mouse set to 1200 baud

update: firmware 2.0 has a mouse baud setting!

The 1200 baud image makes the mouse work under Plan 9 2nd Edition (the driver definitely says 2400 but 🤷 I can't swear my kernel matches my source). The mouse is laggy, but I don't have any basis for comparison to tell where that's introduced; it could easily be an OS issue.

mouse baud setting added in firmware 2.0 :)
