Selling Off My Q-Bus Collection (revision based on suggestions)

by Joe

Hi, located in Eastern MA, I already have a couple of interests, but I'll see what comes in. Multiple q-bus boards that can easily ship, a VT103, a BA chassis 9x4 I think and two RX02 units.

Selling Off My Q-Bus Collection

by Joe

Hi Everyone, I'm new to this list so please let me know if I am doing something incorrect. Anyway, I have a bunch of Qbus stuff (RXV21s, RX02s, memory boards, 11/23s, etc) and I am getting to the point in my life that it all needs to go to a new home. I would like to know if anybody has thoughts on where I should post the list or sell it. I could always do Epay, but I'm not sure that is the best place. I thought here or Vintage would be better but I'd like to hear thoughts from somebody that has already been there. thanks in advance Joe Heck

Indius Java components

by silcreval

A very left field question, but many moons ago I wrote some software using Nescape IFC. For those with long memories that was an early GUI library for Java that predates Swing. For no reason at all I'd like to get this software running again, but noticed that I probably need a 3rd party library that was produced by Indius. These IFC add ons provided a fantastic grid and tree component. The software was I believe finally released with a GNU license in the 00s but despite searching on archive etc I've not been able to find it. Does anyone by any chance have an archived copy ? Netscape IFC was quite a big thing when it was released by the way, and many books were written about it. It was also bundled with Netscapes browsers in the day, so available wherever they were installed. I believe the team that created IFC went on to make Swing, which is in many ways similar, but added a lot of bulk which at least in the early 00s made things slow. Thanks Ian

IDT 49C402BG84 Pinout?

by Holm Tiffe

Hi all, I'm dreaming to build sometimes my own Bit Slice CPU (when I have spare time) and I have collected several IC's in the last years for this purpose. Today a small antistatic bag with 4x IDT49C402BG84 and two IDT 49C410J fell in my hands while I was sorting some stuff. I know what they are and what they could do, they are able to help me to build a Bit Slice CPU w/o very large PCB's connecting hordes of 2901 etc. Besides of that they are CMOS and should draw much less power. But I have a problem with the 49C402: All datasheets that I could find until now, don't have the pinput auf that nice PGA84 package, there are DIP68, LCC/PLCC68 G68 or PG68 and QE68 "Cerquad" pinouts listet in every datasheet, but I have 4 chips in a PGA84 housing... This ebay page has pictures: https://www.ebay.com/p/10020043211 I don't have anything todo with the seller. Can anyone help finding the pinout? The chips itself don't seem to that seldom...

DEC CP11-U (M7824) Documentation?

by Christian Gauger-Cosgrove

Hello all, I'm curious, does anyone have any documentation on the CP11 card punch option? From the '91 Edited Option Module List and various iterations of the "Field Guide to QBUS and UNIBUS Modules" that it's: 1. A card punch, 2. A UNIBUS device, and; 3. It uses the M7824 board. I'm most particularly interested in if anyone has any programming information on it. Best regards, Christian -- Christian M. Gauger-Cosgrove STCKON08DS0 Contact information available upon request.

VCF West 2025 Survey - Mountain View, California

by Jeffrey Brace

SAVE THE DATE! VCF West is back on August 1 & 2, 2025 at the Computer History Museum in Mountain View, California. Please fill out this survey to help us with planning: https://forms.gle/R1kSCsVqEyZfgQ4Q8 This survey is for everyone! We have started plans to make VCF West a bigger, better, and more unique show than we ever have before! We're partnering with the Sacramento Amiga Computer Club and AmiWest to celebrate the 40th anniversary of the Amiga and other special guests. We will have quality speakers, a large consignment area, exhibits galore and our Friday Night Social. Exhibit space will, however, be limited so we are going to be selective in the process. There is still room for talks so if you're interested or know someone who is, please let us know at vcfwest(a)vcfed.org We're looking forward to seeing you there! Take care!

Re: ROM to Flash Adapter for HP Portable PC ROM Drawer help

by Martin.Hepperle＠dlr.de

Mike, you might also want to have a look at https://www.hpmuseum.org/forum/thread-15356.html For testing , I have used a regular EPROM mounted on an external PCB and connected it with a ribbon cable to the ROM drawer. There are ribbon cable - DIP connectors with thin pins, which can be used without destroying the sockets inside the ROM drawer. You should not use normal pin headers as these pins are too thick and will damage the sockets. Unfortunately, many replacement solutions use such headers. You can buy individual, thin pins, but these are relatively expensive (e.g. at Mouser). The height of a replacement should be similar to a normal EPROM, so a thin PCB with a flat SMC Flash RAM might be a viable solution. This will also require a programming adapter. On the other hand, 128 KB capacity is still rather limited - e.g. Turbo-C header files are too large to fit into one EPROM, even if compressed by removing comments and whitespace. However, it should be possible to link software over two 128K modules, as was obviously done with Word Perfect in the days (see the Portable Paper). This linking requires some modification of the FAT entries in the image files, which I have not yet tried. Martin

Need a dot-matrix impact printer?

by Van Snyder

Do you need to print on multi-part carbon or NCR forms? Do you need a dot-matrix impact printer? I have a Star Micronics SB-10 dot-matrix impact printer. It has a parallel interface. My late brother was using it so I assume it still works. None of my computers have a parallel port so I can't test it. Printer, cable, manual, spare ribbon, original shipping packaging. If you want it, it's yours for the price of a PDF shipping label, 20" x 20" x 10" 30 pounds.
