Digital technology evolution

Doesn't ring a bell Andy. We went from ATL to the TAB in 1986 I think it was, so my knowledge of ATL people was limited after that. In fact I'm pretty sure the ATL/AWA link up took place well after 1986.

And I have been retired 7+ years now:-)

Aha! More like the IBM 3330, but IBM did not, as far as I know, have a top loading version. Instead it had slide out drawers, along the lines of the older 2314 "pizza ovens". It is really hard to imagine how many THOUSANDS of those disks, with their 14inch diameter platters, it would take to have the same capacity that you can easily hold in one hand today.

I dont have direct records from then, but I do have some 6502 boards I designed in 1981, and a I know I wrote code for them, first on Apple II and later on the AT clone running under MSDOS 2. But you are right, the AT was not introduced till early 1984.

So much for memory, both the HDD type, and wetware.

Some interesting history at:

Don't think it would be '81. In '85 my school bought a bunch of sperry XT's with twin floppies and mono screen. A year or two later my brother got a 10MHz 286 clone with 40MB hard drive, 1MB ram and EGA graphics. At the time it set him back a small fortune and was pretty much the best that could be got. (It actually turned out to be an 8MHz 286 overclocked to 10MHz). We were in a local computer club and no-one else had ever seen a 40MB hard drive - my brother was pretty much considered a megalomaniac, because no-one would ever need more than a pair of 360k floppies or a 10MB hard drive. Around '89 I got an XT clone with twin floppies, and added an 80MB hard drive around '90 that set me back about a grand. By that time '386's were out but were worth a fortune. And to think that I now carry in my pocket a device with a 312MHz CPU, a

320x480 screen capable of 65000 colours, 128MB of NVRam, 2GB of storage on an SD card, and the whole thing set me back a fraction of what my old twin floppy XT did.

Apparently HDD prices were quite volatile in 1981. I looked at "Historical Notes about the Cost of Hard Drive Storage Space" at

which suggests that US$3300 for that drive was within the 1981 price range. It's amazing to see how much the price/megabyte's dropped since then. :-) NB: Prices on that site are in Canadian dollars unless otherwise noted.
