I just added a different revision of the VP60+ kb to bitsavers with a firmware dump
It appears to be an earlier 2-board version
http://bitsavers.org/pdf/adds/keyboards ... 0+_2-board

ADDS NMB with ANSI layout instead of ASCII, jumperable ADDS or AT
3413-k455-v001 discussed here

If it isn't generally known, Cindy is out of the surplus business now...

Also, I'm the person who runs bitsavers. I do a lot of work with the MAME
team ...

I've been working on decoding the ADDS protocol recently

I'd be really interested in dumps of the ADDS ANSI and 1010 microcontrollers, which I currently don't have on bitsavers under adds/keyboards

ADDS mode requires a 26uS polling pulse ...

I'm interested in getting this for the Computer History Museum
