An Indy for instance, is it much faster then a similarly clocked PowerMac? What about an Indigo 2 IMPACT 10000. Does that blow most PMs away? Anyone using an I2 or Indy with regularity? I have a purple box somewhere. I foumd the teal boxes much more visually appealing.

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.

imd2raw.c correction - linearizing ImageDisk images

by David Schmidt

There have been a few versions of the utility imd2raw.c floating around that will take Dave Dunfield's ImageDisk-created images (i.e. an .IMD file) and make a linear binary image devoid of any metadata. This is similar to the function of Dave's IMDU.COM program's /b switch. I've corrected a problem with the assumption that all imd2raw.c descendants to date have made: sectors that have a skew (i.e. not 1-1 interleaved) weren't linearized correctly. The skewed sectors need to be written out in "sorted" order, which is not necessarily captured/physical order. This is easily verified by comparing output from "IMDU /b" to earlier imd2raw outputs on any .IMD that has a sector skew that isn't 1, 2, 3 [...]. It's up on github here: https://github.com/RetroFloppy/imd2raw

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
