I've used my 120 as a portable terminal. Not too bad if you can get
by the handwriting recognition or tippy-tappin on the little graphic
keyboard with the provided toothpick.
A friend, a number of years back, hacked his box to be a TV remote.

That sucks.
I hadn't heard of Comdex until I read an old
1981-ish article about it in one of my 80
Microcomputing magazines.
Exactly how long was Comdex a yearly event
for?
I think it's stupid that the Comdex management
would sell the email list to spammers... unless
it was just one evil fish in the pond?

PDP-8 is slow, 1.2 to 1.6us memory cycle time (read, modify, write)
so anything under 500ns is overkill.
Cache rams can cycle fast, those from 486boards were typically
in the 15- 25ns range. However, overkill is ok as finding a source
for show rams is unlikely (old 2102s were orignally that slow).
Since most parts I have like the Alliance 7C256 are cmos slowing
them down also allows for lower power. Even if they were
NMOS a mere 25ma (I have some old 61256s) standby would still
allow for short term backup as its only two of them. Since the
system is not portable (it is a PDP8!) and lives near outlets a
wall wart of small size could easily supply the power for the
entire memory rather than resort to battery.
For my case it's not an issue, it's ok if it forgets after power off.
Usually when I demonstrate the PDP-8 I like to toggle in a 20word
program to do inchworm on the accumulator lamps. So even if it forgot
wheres the harm.
I went through the exercise above to point out that with some
imagination there are solutions.

Presumed only. Though with the parts I ahve it would be easy it was not
a significant consideration.

Both are easy to find. My supply of RAM came off some really nice but
excess 486 boards must from the 1995-1998 timeframe.

Hi,
I have an "Apple Adjustable Keyboard" -- a wacky keyboard
that splits in the center ("ergonomic"?) and has an
auxillary "function/numeric" keyboard that sits alongside
it (sheesh! What a wacky arrangement -- how to use up the
most desktop space with the least added functionality! :< )
Needless to say, I am not happy with it. What should I
be looking for as an alternative?
Thanks!

I haven't been following this thread too closely, but you might find some
useful information on the eio.com site, starting at
http://eio.com/lcdintro.htm. There is a discussion of hooking up laptop
LCD's to PC's at http://eio.com/lcdconnect.htm.

Hi,
In an attempt to cut down on the number of monitors, etc.
here, I dragged out an old KVM (which, unfortunately, seems
to have lost track of his wal wart!).
It doesn't take long to realize that this is a non-solution:
- keyboards are PS2, Sun, USB, ADB, etc.
- mice are PS2, Serial, Sun, USB, ADB, etc.
- video is Sun's 13W3, HD15, DEC's RGB, apple's DB15, etc.
Does anyone make a *truly* universal KVM (i.e. so that
I can mix and match all of these flavors)? And, how
outrageously priced is it?
Or, do I just have to get used to hiding "not in use"
mice, etc. out of the way?
Is there any interest in a TI 990 system complete, this has the CPU in
cabinet with switches and lights, complete, manuals, software, and
disk drives including removable disk packs, extras, is exceptionally
clean as in computer room, and was running recently until the business
changed software. Certainly bound to me in much nicer and less-used
condition than what is showing up lately.
Please reply off-list.
