128KB of ram for $6400 ($21,800 in 2007 dollars). That’d get you somewhere around 1.2TB of ram today.
.Small wonder: a breadbox-size computer with up to 1 million bytes of fault-control, semiconductor memory at 5c a byte.
For technically and/or environmentally demanding applications where processing reliability, or high speed, or both, are essential, HP 21 MX and HP 1000 computers can now contain up to 1 megabyte of memory in modules of 128k bytes.
With up to 1 million bytes of fault-control semiconductor memory, HP’s small computers can go to work in demanding applications where large or disc-based systems were previously needed:
