In the late 70s we bought 1.5Mb of memory (512k 52 bit words) of core for our Burroughs 6700 - it cost NZ$1M (about US$1.25M at the time)

- Razengan 8y agoWhat was it used for?
- Taniwha 8y agoThe 6700 was a university mainframe, the only one at the Uni, everything ran on it, from payroll to research. That memory purchase doubled the size of the machine's memory. Memory cycle time was 1uS ... That's read time, core reads are destructive, and you have to write the data you read back, writes were faster ... Read-modify-write cycle could be done in the same time as a read
- tobib 8y agoI don't know what's more astounding, the price per MB or the fact that the NZ$ was once worth 1.25 US$.
- Taniwha 8y agoYeah, I know - you can blame the Muldoon government for that. Mind you access to foreign exchange was limited for ordinary folk back then so you couldn't have benefited from it anyway
