Roberto,
I used RTE systems from 1973 to 1984 including RTE, RTE-II, RTE-IVA, and
RTE-IVB ... I skipped RTE-III which was the first in the series to break
the 64Kbyte barrier. My HP-2100, which ran RTE and later RTE-II, had
64Kbytes of magnetic core memory with a 2usec cycle time. In 1984 or
85, the chip based memory machines were introduced and when we finally
bought a 2113 around 1978, we pumped it up to an amazing 640Kbytes (no
connection to the famous DOS limit of 640K because the IBM PC and DOS
didn't exist yet). The addressing limit for those machine was 2Mbytes
although we always thought in terms of 16 bit "words" since byte
addressing was something only the more popular but less reliable DEC
PDP-11 did. I sometimes feel I was able to do almost as much with the
HP machines, minus fancy graphical interfaces, as I can with machines
today that have 100 times more memory and are more than 100 times
faster.
I probably have some old docs and maybe software on a roll of 9 track
tape in my attic. However it would be RTE-IV vintage because RTE-II was
history by the time I moved on to other things in 1984. If you read
this and say you're interested, I'll rummage around to see what I come
up with.
