I had a licensed copy many years ago for RSX11M but it no longer works. I do have a working copy of Saturn-Calc and Graph (but not WP) for VMS on my MV3100-80 but not the VMS distribution. I have managed to contact the lead programmer that developed Saturn’s software through a former president of the company. The programmer believes he has a copy of the source code for PDP-11 and VAX on a CDROM that is in a storage unit. He has retired overseas and come back home where the storage unit is a couple times a year and I’m hoping he can find the CDROM on his next trip back. I can keep you posted on our progress in trying to recover this software. It helps that the programmer is interested in making the Saturn products available as it may need to be recompiled or at least relinked to be compatible with the newest versions of PDP-11 operating systems with Y2K etc. We thought we had it recovered a couple years ago when nine RX50 floppies were found in Australia that were from a distributor that could be used to generate new customer distributions, but there was no documentation and some info was missing. Also, manuals for the Saturn products have not been scanned so we are looking for them as well. If you had some specific Saturn Calc spreadsheets that you wanted data extracted from, I might be able to help you with my working VMS version of Calc. Saturn Calc was a great product that we used a great deal back in the day. The Saturn Graph product supported VT340s with the mouse and could generate plots a wide variety of HP and other plotters, printers, etc. Best Regards, Mark

fs: Panasonic/Matsushita 9" open frame monitor

by skogkatt007＠yahoo.com

40$ + usps. New in battered box. Apparently this is monochrome and composite (ntsc). It will require a wired connector, or simply soldering wires to a 1 sided card edge connection. Also requires an external 12vdc 1amp supply. A few components are required, potentiometer, 3 diodes, and a resistor if you want graphics. Best done by someone with prior wirimg/soldering experience, but not much. As is, final sale. Check or m.o. Ships from 08758.

It's a IBM PC form factor 68000 based project that was featured in Radio Electronics. Anyone remember it or even know what I'm talking about? It would be a fun prokect.

best C compiler(s) for varied vintage programming

by skogkatt007＠yahoo.com

It cannot rely on bios/ms-dos services for compiling preferably. Iow I'd like to perform what I want to do on the target machine itself, LOL which is hysterical as I've never even seen it boot even once. I could complie on a standard pc I suppose and pop a disk in the Northstar Dimension. It would be nice if it's optimized for it's 80186. Or at least supports it's instructions. My goal is to get MINIX running on it, as the original Netware-86 OS has proven to be more rare then really anything else. From there I'd like to figure out how to support the pc compatible (or so we're told) logic boards that are plugged into the motherboard like standard isa cards, and even have 34 contacts on their card edge. It would be nice if someone had the ideal compiler package they don't need and could sell.

Searching for Cisco Catalyst 3920 Token Ring switch firmware

by John P. Willis

Hello all, As the subject implies, I'm on a search for Cisco Catalyst 3920 Token Ring switch firmware. AFAIK, these units are actually from a company Cisco acquired. They definitely don't run IOS or CatOS, and have an odd full-screen interactive menu interface. It worked when I received it, but after a power outage, the firmware got corrupted, leaving all interfaces effectively dead. It seems that there is no official way to get a copy of the image from a working unit, either, as I've had people attempt it. The general naming pattern is supposedly cat3900-main-gz.x-y-z.bin, where [I believe] x, y, and z would represent some sort of version information. If anyone has this file, or any leads as to where I might find it, I'd be forever grateful. Apparently, even Cisco employees cannot find it nowadays. Thanks much, jpw

Re: Searching for a few good TI Silent 700 parts

by Charles

In fact it is a 745 :) If the printhead has all its pixels working, I'd like to buy it. No keyboard at all, or just nonfunctional? Those particular keyswitches seem to be unobtainium nowadays... thanks Charles On 12/24/22 12:00, cctalk-request(a)classiccmp.org wrote: > Message: 2 > Date: Fri, 23 Dec 2022 10:56:19 -0800 > From: Sellam Abraham<sellam.ismail(a)gmail.com> > Subject: [cctalk] Re: Searching for a few good TI Silent 700 parts > To: "General Discussion: On-Topic and Off-Topic Posts" > <cctalk(a)classiccmp.org> > Message-ID: > <CAHJBWnT0UF8_89CO8FN8g3Bdo63OskjkZPoF9WEODNXEwdpFgw(a)mail.gmail.com> > Content-Type: text/plain; charset="UTF-8" > > Hi Charles. > > Which specific model? > > I have a 745 sans keyboard that can be parted out further. > > Sellam > > On Fri, Dec 23, 2022, 10:54 AM Charles via cctalk<cctalk(a)classiccmp.org> > wrote: > >> I have a Silent 700 terminal that only needs a printhead (several >> missing pixels on mine) and three keyswitches (I have the keytops so it >> doesn't matter which ones). >> >> My other 700 is fully functional and it'd be nice to finish fixing the >> other one too!

Replacing NiCd with NiMH in a pro way.

by Cedric Amand

Hey everyone, No - I won't ask if this is on topic or not :) I'm currently reparing an ALPS plotter ( a Tandy "ce 150" equivalent ) and it's not the first time I face the same problem ; how to replace NiCD batteries. In the past what I did is actually order new NiCd ( you can still find them here in Europe, well actually out of europe but in eastern countries close to europe ) However they are at best NOS nowadays, that does "work" enough for moderate use (I've done that on vintage laptops) This time I'd like to go a bit beyond that and replace the NiCd with modern NiMH (the plotter coils and motors will benefit the extra power) However the trickle chagre of NiCd applied to NiMH will either kill my batteries or kill me in a house fire. I see small $1 NiMH 5S charging boards on Aliexpress, I thought I might use that, try to shove it it the CE150 (or other devcies with the same problem) TL-DR : Before I re invent the wheel here ; Has anyone developed a proper way to replace NiCd with N iMH in vintage (mostly portable) equipment ? And I mean not simply swapping the batteries, I don't want that, I want a proper charge process.
