IIRC, the Ultimate 3030 had a maximum of 2Mb. This required a

ADDS Mentor, based on NCR hardware could go to quite a bit more but I
don't know the upper limit.

What many PICK systems end up looking like as programmers move through
organisations:

I recall the ADDS Mentor machines from the 1984 through to the the Mentor
7000 series (the NCR 3000's onwards run Unix so not a true native "MENTOR"
machine).

Our first Mentor was the Mentor 2500 - i seem to recall it having 256kb of
memory, 16 serial ports and I think a huge 15mb had disk which needed both
hands to lift! I think the larger machines of the time (the 5500?) could
run up to 4mb of memory though maybe a little more.

The 6000/7000 series machines replaced all the older ADDS machines. These
were rebadged NCR machines using Motorola 68020 (6000) and 68030 (7000)
processors at 20/25 and 33 mhz (I think!). Memory started at 1mb and I
think we ran them up to 16mb though maybe a little more. This is nearly 20
years ago now and my memory is fading!!!

Of course on the way there were PCOS variants of mentor which ran on
ordinary PC's, starting with the ADDS 1500 which was based on the original
IBM architecture with 512kb of ram, followed by the 1700 which was an IBM
"AT" clone with 640kb. I think there were larger ones with 1mb ram.

All this reminds me of a) how old I am and b) how amazing it was that these
machines ran at all! My new PC (Intel Xeon Duo 2.66ghz, 2gb ram, 500gb
disk) probably has more power and memory than all the ADDS machines I
installed in the 80's! Unfortunately, it will probably only be just
powerful enough to support my visual studio based development environment!

Simon

The windows registry and all of the system settings could have been
done using SQL.

I bet it's not even done that way in Vista instead we have the
diabolical text file which is the registry.

Anybody read/understand Japanese enough to know what they're singing or what
the signs say?

Finding some bugs in Pick Virtual make some of these contraptions look
pretty simple.
