$529 each for the 16K.
Today I took delivery of a new disk drive because one of the current
ones on my computer has been acting up...it cost about half as much
as those old memory cards,and that it includes eight thousand times

For those who wanted to move beyond loading software and languages into
the Sol's memory from audio cassettes whenever starting it up,we were
able to get single-sided,single-density,hard-sectored 5.25" floppy disk
drives ("diskettes",to pedants,since the more expensive 8" floppy disk
