I picked up a TI Silent 700 model 707 recently (a nice, small variant with built-in modem, see http://pobox.com/~fmw/misc/Silent700.jpg), with hopes of converting to use as a direct line serial terminal. Before I open it up and poke around, does anyone already know how to do this? Portwise, there are two RJ11 ports (phone&wall) and a 6-pin acoustic coupler port of unknown pinout.

preserving / ressurecting old docs?

by mrbill＠mrbill.net

As mentioned previously, I've registered DECDOCS.ORG, and have started the tedious task of scanning in all the documentation I have. I'm about halfway through scanning the '69 DEC Logic Handbook (positive logic edition), by laying the book as flat as possible (not using the scanner top cover), and scanning 2 pages at once. Some of the pages are starting to come unglued, and I'd like to avoid destroying the book while archiving it. Any suggestions on what to use to re-glue the pages, or rebinding, etc? I've got quite a pile of these handbooks and will be doing the same (scanning) to them, but this is definitely the oldest / most fragile handbook in the collection. Thanks for any tips.

I'm currently working on a home automation project using OPTO22 technology. I have found them to be easy to interface, flexible, cost effective, and very reliable. The devices are controlled via a RS422 serial interface (easily converted to RS232) and drivers are available for a number of OSs including DOS, WINDOWS, and Linux. The protocols aren't that complex so writing your own driver, if one is not available, wouldn't be too difficult. Most of the work I've done so far is basic experimentation and prototyping. I currently have a OPTO22 controller interfaced to a HP 9000/832 running HP-UX 10.20. It can turn on and off a few lights, measure the temperature in the house, etc... All the collected data is captured into an Informix DB. The application(s) are written in PERL / CGI and I have put together a rudimentary web interface. I don't have a static IP otherwise, I'd publish the address so others could see the system in operation. My ultimate goal is to build an automated Printed Circuit Board drilling machine using a classic HP 3000 MPE computer running COBOL. I'm not sure if OPTO22 is suitable for that application or not, I'll need to do a lot more experimentation to make that determination. If it's too difficult, I may wind up using a STD BUS computer as a smart controller/interface between the drilling machine and the 3000. FWIW: All the hardware I'm running is over 10 years old so, it is on topic. With the exception of the 9000, most of it is closer to 20 years old.

More free stuff...

Furthermore, Bay Networks was formed from a merger/acquisition between two previously-separate companies: Synoptics and Wellfleet. That happened in the mid-1990s sometime, maybe 1994 or 1995?

A little OT: List of users who is getting CSA Software/Manuals/Inmos Books

by rmeenaks＠olf.com

Hi, Just to make it clear, all the transputer stuff is now gone. Here is a list of people and who is getting what: Hans Franke - one box of CSA transputer software Tony Eros - one box of CSA transputer software + Inmos ANSI C manuals Graham Scott - one box of CSA transputer software Michael Haas - one box of CSA transputer software + CSA transputer manuals Danny Rafferty - one box of CSA transputer software Dave Lowry - one box of CSA transputer software Jeff Shaw - one box of CSA transputer software If you have not already done so, please send me your addresses, so that I can find out what the shipping costs are. For others who werent so lucky, most of the software or equivalent to can be downloaded from my website at http://members.nbci.com/transputer. For others who is looking for a transputer, but doesnt have one, I suggest you take a look at the "transputing without transputers" section on my website..... Cheers, Ram

So, that shouldn't be too big a hurdle. Since I've never done any terminal I/O programming on the 3000, I decided to start with the 9000 which is much more familiar. Once I have a proof of concept running, I can port it back to the older box.

Dutch auction for 20 T8 transputer cpus on ebay....

by rmeenaks＠olf.com

Hi, A dutch auction for 20 T800 Transputer chips is currently running: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1250072346 Its a bit pricey IMHO, but with the shortage of T8s in general, it should go pretty fast. Any commercial users of transputers out there????
