Also these sold as Omega/480 and Olivetti 5300 series. Later CMI made their own versions and I believe this one of those. But I haven't found model 1640. So is this 1641..? What is difference between CMI and others? Microcode?

Wow!  solid state memory and ECL chips for the CPU!  Going 
to be real hard to find the missing items unless somebody 
who worked with them hid them in their garage.  Anyway, such 
a machine is pretty useless without a bunch of peripherals.  
You'd need a disk control and drives and a comm control to 
be able to do much of anything.
