Fancy. I picked one up at a junk store in L.A. a couple of years ago for $10.
It just had wires dangling from the end that originally went to some PSU
somewhere.
I was especially interested in this because it had a built-in EPROM programmer
and a couple of S-100 slots (unpopulated in mine, and needing +8V unreg)
If I still had any S-100 boards, I'd have probably done more with it by now
(I gave away all my S-100 goodies to a friend a number of years ago - all
68000-based, lots of serial ports from a project from work)
Do you have any plans for your Starter Kit?

I assume you have seen the stuff on highgate and my website.
I am working on a search for the documents, Highgate doesn't have
all the scanned documents online, the search will have them all. I will also
have the search have the option of converting to PDF. I will post to the
list when it works. I also have more 8/I stuff not yet scanned if you need
something in particular. I have put a no longer accurate list of
manuals I have at http://www.pdp8.net/document.txt
I also have spare boards if you find you need them. I normally try to
trade for something (extra hardware/docs or copies).
A lot of paper tape images are available on the net. With the right
adapters you can hook it up to a PC to download. I have done this with
my 8/I. See http://pdp-8.org/papertape/. You should also be able to
punch physical copies with your punch and a little software.
If you have TC01 with a TU55 or TU56 I have 4K disk monitor system which
says it works off of a DECtape also. I only ran it from DF32's.
The manual is already scanned, I will get the tape on my site and send
to pdp-8.org. Email me if you can't find it when you need it.

I've had an -8/i since high school. I rescued it from a public school
locally (I already had an -8/L, so I knew what I was looking at). Mine
came with 4K, a DF-32 master and two slave disks. I have no expectations
that the media are any good at this point, but the last time I fired it
up, the controller was working enough that I could read the status register
and watch the rotation sensor on the console via a tiny toggle-in program
I wrote to check it (I had to rebuild the rotation sensor on one drive
because it caught fire in the housing!)
There are some docs on Highgate and you might be able to find the DEC 1970
Small Computer Handbook for the basics. If you care to try out any papertape
or DECtape programming systems, you'll want the Programming Handbooks. There's
good info in those on how to load and start FOCAL, etc.
Have fun with it; I wish I had reasonable peripherals on mine. The best I
can do is move my PC8 to it and load paper tapes faster. I have a TD8E and
a TU56, but nothing for an older machine. I suppose I could always wrap
one up - I do have enough spare parts, just not enough spare time.

Exactly, Anyone with 8085 experience could easily loft the design to
an 8088. Intel even had an ap-note to put an 8088 in an SDK-85 board
(I did it too) and it was pretty easy with the big difference being the
monitor rom.
Keep in mind the design window was in 1980 and by then the 8080
was a non contender as the 8085 and Z80 had replaced it. If you
look at the late '79 and early 1980 mags (Byte, KB, IA etal) you
would see there was an emerging push for more cpu, more bits
to do math and more bits for addressing. If they used an 8085
(or z80) they were an also ran to tandy, Apple softcard, NS and
a raft or other already known 8bit systems. The only place
there was room to make a point was the 16bit front and the 8088
was a well known (it had been around for about two years)
relatively cheap way to get there.

In my continuing quest to make the VCF Link Library ever more useful, I've
split up sections into sub-sections where applicable.
For instance, the DEC section is now split into PDP-8, PDP-11, VAX, etc.
The Apple section is split into Apple ][, Macintosh, Lisa, etc. You get
the idea. Also, specialty sites for each section have been split out,
such as Software (for sites that have software resources for computers in
that section), Documentation, Emulators, etc.
Check it out at:
http://www.vintage.org/cgi-bin/links.pl
There are currently over 700 links total in the database!
If your site is not listed, add it now!

FWIW, it looks fine to me, using Netscape Communicator 4.07/SGI/IRIX 5.3

I have a Z80 starter kit which I've torn apart and reassembled. This one
is rather nice in that it came with a power supply, connectors and a
wire wrapped section already added. It was probably used at a local
community college (Mercer?). The wire wrap job is very pretty (hey it's
art work :-). I also picked up an Applied Microsystems Corp. EM-180B (Z80
diagnostics emulator). Soes anyone have any docs on any of this?
I've had experience with the emulator (I worked with the 6802 and 6809
emulators). So I've been able to use it, I just want to know what the
rest of the bells and whistles do.
Thanks

Carlos,
Keep me posted about what you find. I've only seen bit rot in the HP
41 plus in ROMs. I've never seen it in other HP machines.

I run a Tandy Model 100/102/200 mailing list (the NEC, Olivetti & other
Kyocera-OEM'd laptops are also very welcome there! ;-) and this person
posed a question about repairing her Portable Disk Drive. Can anyone here
help her?
You can reply directly to the poster, or you can reply to the mailing list
(m100(a)list.30below.com) as it's an open list - you need not be subscribed

Recycling is good, right??? Ok, so I'll recycle an old .sig.
If at first you don't succeed, nuclear warhead
disarmament should *not* be your first career choice.
I looked but didn't see a model number in any obvious place. I bought it a
long time ago because I was fascinated by the Tektronix displays used in
the "Battlestar Galactica" TV show. Unfortunately I never got my hands on
the documentation for the graphics display commands. I would have loved to
get copies of the programs they used for the show (even now that might
persuade me to keep this terminal).
The terminal itself isn't very large, but it does have an integrated floor
stand and is rather heavy (shipping might not be very practical). I live
in the Portland Oregon area; if you're within reasonable driving distance.
I wasn't planning to ask for money, but I do have a wish list that
includes a Kaypro, Osborne, Zorba, or some other interesting portable CP/M
computer. If you're interested, feel free to contact me (even if you don't
have anything to trade). I'm trying to free up some space to make my wife
happy...
