I used a bunch of their multibus development boards to build a mutiprocessor system to add on to a VAX. It worked, but the methodology for general users to set up programs to run on it was too much for our users. I had 7 32016 CPUs with local memory and access to 2 MB of shared memory on the multibus, and a DMA controller to move data between the multiprocessor system and the VAX. The only bug I know of was the hybrid bus controller chip they used on the multibus card didn't have synchronizers on it and would hang. After working with Nat Semi, they sent me the schematic of this module and I added the 74S74 synchronizers to it and it worked. But, that was NOT a Nat Semi product, just a "chip" they bought.
I also cloned a Logical Micro Co. Unix system and had it running at my house for a while. It was cool, but really slow, running emacs on it was sluggish, very much slower than running a fairly sophisticated editor on a Z-80 CP/M system from more than a decade earlier. I didn't have really fast memory on that system, so that might have been part of the problem.
