I have raw 9900 chips but TI made both a system and board level
products using that CPU. The tek and fluke equipment I know about
but they don't thrill me.

I don't do Ebay. It involves more trust that I am able to muster.

There has been a thread on having the correct tools to work on classic
computers. I like to collect tools so I don't have a problem with that.
There is a recurring thread about how PDF files are a closed standard and
some people do not have a computer that will display them.
The most of distributors that I shop have their online catalog in PDF, same
with the part manufactures. There is a wealth of classic computer documents
available in PDF. In 2005 PDF files a very common in society. Most
government publications are in PDF.
You are making life difficult if to don't have a tool for reading PDF files.
I think you can buy a nice one for a few hundred dollars.

Hi Guys,
FYI I've just posted a significant update to my site. Which includes:
- Quite a few new machines (list below)
Not all of them have in-depth coverage yet, however there's lots of
photos etc.
- A new section on S-100 cards, with photos and documents (where
available), including a number of docs that I have recently scanned
which may not be available elsewhere.
- Quite a few new disk images, including a lot of new NorthStar
images (I am currently "mining" a stack of many hundred N* disks)
- Updates/latest versions of my simulators and transfer utilities.
- Misc. updates to various other sections.
- Probably more stuff that I have forgotten (It's been a few months
since I started the update - Whew!)
Enjoy,
Dave
I case anyone is interested, here is a list of the new system
(most of them anyway):
S100 : IMSAI 8080, NorthStar Horizon, Compupro, Cromemco Z-2D and
Early System3, Wynchester, Multiflex, Protec PRO-80,
Compuduct Rainbow (oddball S-100 system)
Other: BMC if800, MAI Basic4, Xerox 820-II, Nec APC, Nec N5200,
DEC Rainbow 100+, Nelma Persona 100, Visual 1050,
Megatel Quark, OSI Superboard II, Acorn Atom, Altos 586

Just like Dave, I have been a bit busy.
First, with the resurrection of a PDP-11/60 from a low boy
corporate cabinet into an H960 tall rack, doing a bit of
DIY work to make all fit and taking pictures in the process.
Edward and I went to the UK 10 days ago, where I picked up
the 11/60 (Edward got some goodies too), and then we spent
a very nice weekend at Pete's in York.
Sunday afternoon I even found some time to work on my site.
Check out www.pdp-11.nl and especially the "PDP-11/60"
folder, and of course the link "11/60 in H960 rack" :~)
Some XXDP doc is also added, but I have not yet shot pix
of the boards ...
I have not yet read about the diagnostic LEDs on the FP board
and the LEDs on one of the CPU boards, so any info / comments
are most welcome!
greetz,

I found a site with a couple of formatters that may work:

Actually a lot of them ran the fastest 8088/6 (12mhz parts) and
had mapping for more than 1meg of ram.
Generally S100 based 16bit systems ran ahead of PCs for overall
performance.

If the author has set the security on the file to not allow
printing then Adobe reader, and even the full Adobe acrobat,
will not print the file.
Other tools may though.
