Unlike the previous VLSI microprocessor we know quite a lot about this one because we found the 32 page DATA SHEET for it on the WEB at www.alldatasheet.com.
The 40 pin ceramic package containing the silicon chip is 50mm long and weighs just 4 gram. The actual chip is just 8 x 6 mm, exposed when I unsoldered the cover protecting it.
It is a complete CPU just like the AMDAHL stack which weighs about 100,000 gram,
(I have not been able to weigh it, it is so heavy, it needs two people to lift it.)
albiet there were differences:
The MC6800L microprocessor used 16bit to address 64KBytes, this included the I/O devices. It had three 16bit registers, three 8bit registers and a 72 instruction set that did not include multiply or divide.
This really is the beginning of the end of the mainframe computer.
