What is this board?
Made by Emulex. Has ASSY# SU0210401. ROM on board says "SC0210201-AXC W/
Boot Strap".
Has on top two 26-pin connectors and one 60-pin.
"Ditronics-I" silk-screened on board in tiny letters.
Ideas?

Did you find a terminal? My father has just put on an HP-2648A Terminal on eBay. Just look up HP-2648A and it will pop up if you are still interested in one, or know someone who needs one. We also have other HP items up for bid. If there is any other older calculator or computer parts you need, my father might have it. thanks, Becky

LOL... yes, I was thinking wrong. I remembered it as being 1000 Hz tone,
and for some reason I decided that was 1 MHz, not 1 KHz.
My bad (and that is exactly why I said I would have to look it up to be
sure)
But hey, my doctor always did say I had the best range of hearing of any
patient he ever had :-)

Just for the record I want to say that I agree with every single point
made by Tony in this thread, without exceptions.
It looks like we are the only two TRUE ClassicCmp'ers in the world.

While of course a re-ASCII-fied document would be infinitely better, a
PostScript page description that uses nothing but the image operator is
still not totally useless to Classic computers, since it can still be
printed on a Classic PostScript printer, and the act of printing can be
performed from a Classic command line OS.

That is why we need a socialist government that would eliminate unemployment
with a massive public works program that would hire millions of people to
do the re-ASCII-fication work.

Actually I think its a small PCB with an IR receiver and a IC chip of some
sort which stands off from the main board. I am not sure it would much
help for
him anyway.

Rich, I would like to see pics of the final project. I have considered
doing this
with a dead PCjr for a while. Have you been to the mini-itx.com site?
Max
For your consideration:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=378&item=4523753903&r
d=1
Due to the size, might be a good thing for someone on the West Coast to bid
on. Just posting the link...I have no connection to the auction at all.
There are some nice databooks in this lot...

Hmm, maybe; maybe not. A Beeb enthusiast named John Kortink has
produced an MMC interface for a BBC Micro. It's called GoMMC and it
allows you to store files using a normal BBC filing system on a
MultiMedia Card. Actually the card stores disk images, but makes them
available to the normal filing systems. The card can also be
read/written on an IBM PC (so you can move it and back it up). Take a
look at

if you're interested.

Apologies if this is too new to be officially on-topic, but as a
slightly newer expression of Newton hardware, I hope an eMate question
won't be completely inappropriate...
I have these two eMates here... I got them at 'parts' prices because
they were listed 'as-is' with "ribbon cable problems"... both fire up,
show stuff on the screen, and neither one seems to have a working
digitizer ("tablet"). One also has some dropped pixel rows on the
left half of the screen - looks like a bad driver or bad line on the
video RAM, but there's enough of the screen legible to see what's
going on...
I have taken the one with the video voids apart completely, and an
trying to figure out where the problem might lie. After completely
removing the video ribbon cable, I tried a white eraser on the
contacts (vinyl, not abrasive like a pink pearl), and hooked up the
display to the screen with the boards on the table... no change in
behavior. The keyboard and CPU seem to work fine, and I'm getting
reasonable behavior at an OS level, but no apparent perception of the
stylus on the screen.
So... are there any Newt experts that might be able to shed any light?
I've been grubbing up FAQs left and right, but they don't go to this
level of detail... at best, I have the Apple eMate service manual
which _does_ describe in sufficient detail how to dismantle the beast,
but it only references a PCMCIA card with pre-loaded diagnostics on
it, nothing embedded in the ROM. :-(
There don't appear to be any crimps or tears in the ribbon. I can't
easily inspect the connectors on the motherboard or display, but there
are no obvious external mechanical problems (i.e., the latches all
seem to be good, no tool marks, etc.)
Thanks for any pointers
