You don't get a back light, it's not preassembled and features like
bar graphs are not done in firmware, but you can display the same
information at less than half the cost, if you do your own assembly work.
I have submitted code for lcdproc-0.3.4 (to be known as 0.3.4.4 when it
is released) and am working on code for lcdproc-0.4pre2. My LCD web page
is at http://www.infinet.com/~erd/lcd/
For the really cheap who don't care if the LCD panel soaks up more cycles,
you can drive a panel from any sort of parallel port (even a PET!) Support
is already in place with lcdproc-0.3.4. You need four bits for data,
eight if you are worried about bandwidth and have bits to spare, and three
bits for control.
If you don't know which end of a soldering iron to pick up, go to linuxcentral.
Enjoy,

P.S. Any interest in LCD code for the 6502?

And for the cheap but practical, just buy an old laptop for $20, and you
can use it as a CPU meter, dedicated FAX, whatever....

I saw two Toshiba 1000E laptops at a thrift store today. $9.98 each.
Nice shape. No idea of working condition and they don't come with power
supplies. But a nice little unit for homebrew stuff, and they were
definitely nice designs for their time (somewhere around 1987 I would
guess).
Anyone want me to grab one or both?

For that kind of a price difference I think I wouldn't mind being called a
cheap bastard!
However, in looking at the URL's that have been flying about I notice that
they've apparently got the Matrix Orbital modules with the Keypads working.
Now that's what I really want. I'd love to be able to punch a couple
buttons on the front panel of my computer and get it to reboot, halt, or
play my favorite MP3's! Besides I prefer the looks of the VFD's to the
LCD's. Be pretty wild if I end up buying a bigger tower case to put a
front panel on it :^)
People interested in this might want to look in the applicable hardware
directory on Sunsite also. Following the links on this kind of stuff a
couple months ago, I discovered it's got some related projects that include
using LED's IIRC.
P.S. Any interest in LCD code for the 6502?
No, but I'd love to see it for the PDP-11 :^)

Ooh! There's a challenge. To keep this on the classiccmp topic list... how
would it be best to attach one? Serial, obviously, but what OS? I could
cobble some MACRO together in a few hours to drive a serial LCD on demand

lcdproc 0.4pre1 (and up) has a joystick driver for buttons not attached
to the LCD module. I have been frantically looking for my Gravis joypad
to no avail. :-(

The VFD's are way cool and twice as expensive as the expensive LCD's. I
want one too, but not at $150+.

interest in LCD code for the 6502?
No, but I'd love to see it for the PDP-11 :^) from RT-11, but I never did much more than FORTRAN on
RSX.
I wouldn't guarantee most lcdproc clients would work on RT, but it might
be possible to port it to RSTS in toto. Are there any RSTS-internals
guru's out there? The default lcdproc clients give current time, uptime,
CPU usage, load (graphically) and memory stats. I'm porting the clients
to Solaris and find that I need to know the total memory, the swap size,
the swap in use, the physical mem in use, percentage of CPU in user mode,
system (kernel) mode, free and "nice"'ed, uptime and current wall time.
How much of this is accessible from RSTS? Most of it is irrelevant from
RT, ISTR.

Hrmmm? OK, I'll show my lack of non-UNIX PC knowledge here, what does a
Gravis Joypad connect to, and would one work on a Alpha Multia?

ideally more.

COOL, how much of that would be applicable to SunOS? Myself and one of the
people at work would love to see about connecting this to an Auspex, and
they run a chopped up version of SunOS.

Don't know about RSTS, but most if not all is available to RSX.

lcdproc 0.4pre1 (and up) has a joystick driver for
buttons not attached

to no avail. :-(
Hrmmm? OK, I'll show my lack of non-UNIX PC knowledge here, what does a

lcdproc is written in C. I was contemplating just some basic string
printing stuff for RT, not lcdproc.
...I imagine that it's heavily involved with the
Linux /proc filesystem.
Yes it is. :-( I'm attempting to unhose that dependency with Solaris.
I think for RSX or RSTS it would be cool just to have
it show how many
users are currently online and that the system is running. Of course
ideally more.
As long as those stats are easily garnered from the OS, it's a snap.

Dunno. I have never attempted to aquire kernel stats under SunOS. Solaris
is bad enough. Some stuff is easy, other stuff you have to walk the entire
process structure and tally each individual process. :-P

New subject: LCD displays (was something else)
Yup, I found 'em. Waaaay overpriced. I'm going to build one, I expect it
will cost about $20 in parts. Looking at my favorite LCD suppliers I find
that one could actually put a 640 x 200 LCD in a two high bay these days
which would give you a full console view if you wanted it. Intriguing idea
but somewhat more expensive.

To drive an HD44780-based display over a parallel port, that's about right,
less if you've got cables and connectors and stuff lying around.

Some friends of mine and I are working on such a device. We are considering
various features like an LED bargraph, buttons and a pixel-addressable LCD.
Visit http://www.infinet.com/~erd/lcd/ and when something is likely to see
the light of day.
At some point here, I will post some code to that same web page for the 6502.
