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

Re: Searching for a few good TI Silent 700 parts

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.

Toronto CompuFest ads

by Ryan de Laplante

I remember seeing full page CompuFest ads in the Toronto Star back around 1996-1997. CompuFest was one of the highlights of the year for me and I tried to go every year with friends. Has anyone ever seen one of those old ads online anywhere? Or maybe you have a newspaper or magazine with the ad that I might be able to buy from you? obsol33t
