A few days ago I talked about wanting to get NeXT's OpenStep running on my MacBook Pro in either Parallels or VMware Fusion.
I'm narrowing in on a vendor that has the software I'm looking for. Bonus points for the vendor for having the authority to resell the software with Apple's blessing. I will post more details about the vendor and purchasing options once the software becomes available for purchase.
In the mean time, check out the video below for a 'live' demo of NeXTStep running on a greyscale NeXT Cube powered by none other than the Motorola 68040 processor. The same processor that was used in the 1991 Apple Macintosh Quadra 900.
