You had that much memory? Used to run a time reporting system on a 3b2
400, 4MB Ram, WE32100 10MHz processor, 1.1 MIPS. Flat file home grown
database system that used indices in shared memory and semaphore
communication between three continuously running processes.
The application ran in pretty much all the AT&T factories at the time.
