I have a small Windows LAN at home, but no Unix boxes setup. I guess
that this weekend I'll be setting one up...

It is the "09" ROS. Here's the diagram that I got from Philip Belben:

:As Joe said, HP classed a lot of things as 'calculators' to get

:IIRC, officially the HP71B is a computer (QWERTY keyboard, Basic),
:but the HP48 is a calculator (alphabetical keyboard, RPL). They use
:virtually the same processor (Saturn), although the HP48 has a few
:more machine instructions.
cx ( <- hello, from firstborn)
it's possible that marketing could have something to do with that too.
we'd rather, and we suspect most engineers would rather, use the hp48 -
but since rpl fits in well with hp's use of rpn in its calculator range,
it probably fit better into the calculator family, and would have been
more targeted at the engineers who cut their teeth on its predecessors.
:> (or do their design engineers just design things they can hack
:>between meetings? ;> )
:You mean _during_ meetings, surely...
well, we meant between design meetings, when one would assume they'd all
be focused on designing the next piece of kit they could hack during
meetings with the pointy-haired bosses... ;>
(now someone's going to turn round and tell us that the pointy-haired
bosses in hp hack on their hp48s during meetings, and wear their hair
that way because they don't know where to find a decent hairdresser.
we've heard about hp.)

I think what I'll probably too is trash the HD on an "experimental" 486
that I have and install either NetBSD or SCO OpenServer. From there, I
should be able to create a boot tape and an install tape, and then start the
install from the 3/50

Thanks for the SAH list. I already belong. No specific ideas from anyone
there yet.

oh, yes, we'd forgotten them... does anyone know where we can *get* one,

:I bought several and am toying with making a few "ultra miniature"
:computer accessories ("matchbox" computers?)
off-topic, but...
the computer we would really love to use has a main box that's the size
of 2 3.5" floppy drives one atop the other, and standing on that is a
little 6" mono crt with a resolution of 384x256. the keyboard is about
the size of the keyboard on the cambridge z88. the processor is a
hitachi 6309 running in native mode, and the software is forth. and you
have to hold the thing when you put a disk in. needless to say, there's
no hard drive, but the floppy can fit 1800 screens on it, so that's no
problem.
of course, it was never made... but we'd love to see it.

:Another thing worth grabbing are old data books. There are standard

before we were seriously interested in this stuff - or rather, since we
were designing 68000-based computers at the age of 12, between interests
- we had a whole stack of data sheets donated by a teacher's boyfriend
who worked for the uk distributors of sage before they became stride.
(what happened to them, btw?) it's a damned shame that when we were
about 16 we threw the whole lot out to regain some space in our bedroom.

max eskin...
:I have heard enough on this topic without understanding what it
:meant! What is the difference between vector and bitmapped graphics,
:and who was first to use each? Why are vector graphics
:stereotypically used in mainframes and bitmapped used in cheap
:weenie "home computers"?
dunno about first - but in vector graphics, you have a crt under direct
control of the computer, and you tell it to go to a point, switch the
beam on, go to another point, maybe switch the beam off, etc. etc. very
high resolution, but refresh speed is inversely proportional to the
number of lines on the display. in bitmapped graphics, you use a
conventional rasterised display (the horizontal lines) and a map of
bits which correspond to each line of the display and say whether the
beam is on or off at that point. unless you count williams tubes, vector
graphics came first, because you could use any old oscilloscope and
memory was precious. now memory is cheap enough to make bitmaps viable
in even the smallest computers, and monitors are readily available. the
price paid is blocky lines.

crock!
PT like many of the time were susceptable to the volitile market and
over extended and went under. Good machine and the Persci drives were
very late in the program when they were nearly gone.
I think the SOL-20 was about 10,000 before the folded.
