(Re: those cables) I mis-phrased, intending to say I presume Seagate ensure supplied cables work properly with their HDD.
Seagate. like every other manufactuer, use the cheapest cables they can get. USB cables are basically two kind. One is used for charging devices, and the other is used for data. In fact, both are the same (although some charging cables don't have the data wires). I would expect the USB cables, that come with any device, will work with the device. The connectors, and the legth, are the inportant parts.
(Re: the Apollo Lunar Lander)
16K, in those days, was a huge amount of memory. Remember that it was not running an operating system, only a very specialized, highly optimised, program.
we hear Not A Lot about Error Correcting Code (ECC) RAM in office m/cs.
ECC, when it was first developed, was am expensive stop gap for poor manufacturing. Today it is an advertising gimick. Memory rarely fails, eliminating the need for ECC (which is just as likely to fail, and slows memory speed). It is generally only used for "mission critical" computers (usually in hospital monitoring machines). If those who mandate that (usually governments), really understood it, thay wouldn't bother.
