This is a quick and dirty program I wrote to set the CPU speed of my NuXT v2.0 motherboard, which is handy to use in a batch file before running certain programs. It does absolutely no error check to see what kind of motherboard it is running on. Simply type SETSPEED with 4, 7, or 9 as the parameter. This based on the code from the Micro 8088 BIOS source code on GitHub. ASM source is included.

SETSPEED 4 - 4.77MHz
SETSPEED 7 - 7.16MHz
SETSPEED 9 - 9.55MHz

I got confirmation from a user on the Vintage Computer Federation forum that it is working with his NuXT as well as his Micro 8088 system.
