Anyone out there got proof, one way or the other? I saw a "company confidential" logic diagram for the 8600's ALU (Arithmetic Logic Unit) that showed it was capable of doing 36 bit arithmetic. The internal registers could be configured to be 36 bits plus parity or 32 bits with ECC. Many parts of the design were not specific to the KL or the VAX and were used on both. -- Joe Smith (408)922-6220 | SMTP: JMS@F74.TYMNET.COM or jms@tymix.tymnet.com McDonnell Douglas FSCO | UUCP: ...!{ames,pyramid}!oliveb!tymix!tardis!jms PO Box 49019, MS-D21 | PDP-10 support: My car's license plate is "POPJ P," San Jose, CA 95161-9019 | narrator.device: "I didn't say that, my Amiga did!"
