I have a complete, wire-wrapped clone of the Logical 
Microcomputer Co. 16032 system, except for memory and the 
MFM disk.  So, that's the CPU on Multibus-I, a Taisho disk 
controller, and a board with 5 2561 (I think) UARTs for 
serial comms.

I ran it for about 18 months, I think, until I had the 
incredible fortune to be able to buy a microVAX-II.  The 
16032 with Multibus memory and MMU turned on was just 
glacially slow.
It took several minutes for emacs to load, I'm not 
exaggerating. Maybe I didn't have enough memory on it, and 
of course an MFM disk is kind of slow, too.
