There is very little documentation out there, as IBM could not go all out with manufacturing it as a stand alone CPU due to Intels licencing... so it could only be manufactured if it ws sold via 3rd party motherboard makers i.e. Alaris. Either this method, or the other method they utilized was by having PGA 132 pin upgrade daughterboard modules... these are notoriously very hard to find.
It is actually just a clock multiplied 386, with a 486 instruction set and a whole load of cache... seriously it is quite a specimen. If you accidentally come across one... keep quiet about it and contact me ASAP. I shall reward you generously. 😁
Blue lightning is a verysmart little chip, hope to find one on a motherboard one day, with luck something I stand a good chance of running on a standard PSU.
AMD K5 166+ has become a firm favourite for me this last few weeks, the little chip that could, exceptional performance for a 117mhz socket 5/7 CPU.
