Well, it was right around 1979-80 when I paid $50 for the DRAM but I 
suppose SRAM was even more precious at that time.  Prices were also very 
volatile during that period. I can remember in the mid 80s a company 
that I worked for bought a ramdisk card for a DEC PDP-11.  I think it 
must have been maybe 128 or 256k and it was somewhere around $900 I 
think.  The instructions that came with it required us to type in a 
bunch of octal codes into a monitor/debugger with a serial terminal to 
patch the OS so the ramdisk would be recognized. I have no idea why that 
couldn't have been put on an 8-inch floppy.
