Funny, I don't seem to be able to find 1.6 Meg x 8 bit > static RAMs, or 1.2 GHz CPUs, at my local suppliers. Certainly I haven't 1982: 1 Megabyte of dynamic RAM on a Multibus board 1990: 64 Megabytes of dynamic RAM on an SBus board (1/3 the area of a Multibus board) (factor of 190) 1982: .1 MIPS 8088 1990: 20 MIPS '486 (factor of 200) 1982: 10 MByte 5-1/4" hard disk 1990: 1.2 GByte 5-1/4" hard disk (CDC Wren VII) (they are real) (factor ofr 120) So, maybe 200 is stretching it a little, but I think I can support a claim of a factor of 100, with some room to spare.
