Adata PC100 256MB memory and more
by Bob Flanders 12 Jun '20

12 Jun '20

Hi, I recently found some old pc100 and ddr2 memory. I could chuck it, but I thought that it might be something that might interest someone. Does anyone want it? Let me know and I can send it to you.

OT: All-In-One Color Laser Printer

about OT: Color Laser Printer Recommendation Dave McGuire posts: > Very nearly universally, ink jet printers are garbage. I concur, conditionally. I'd call them disposable. I buy one every few years, half price when that model is superceeded. I use them to scan 11 X 17 documents. Not for printing, the heads clog up! They die, plastic parts break. I replace it, long after it stops printing. I haven't replaced ANY inkcarts, which cost HALF the sale price of the printer. And the new printer has more features than the old. Thus: disposable printers. I have an Epson WF-7520 to dispose of now; it's busted and clogged of course but still scans. My average inkjet-printer+ink costs as a result: about $50/year. New strategy: print once/twice a week, see if I can stretch out the printing. This will cost me a set of $70 inkcarts to continue; I'm several months in. > my main color printer is an HP Color Laserjet 5550DTN, > Either way, I would not recommend buying one new. I concur, on practice and brand. Thrift stores or surplus sales or maybe recyclers provide laser printers cheaply, tens of dollars. Maybe Craigslist? Freecycle? HP supplies abound on eBay. HP printers work for DECADES. I've used HP Laserjet II's and III's until the scanner motors die; that's 1990's tech, last used in *2018*. Those, I can fix. Hey: vintage tech! We are back on topic! ;) My daily B&W laser printer (and my wife's) are both HP LJ 4300's. I bought a new old stock toner cart on ebay for $18 *delivered*. My funny story: my winning bid on a cheaper toner-cart was canceled, when the seller realized their shipping cost was more than their selling price. > [story of outrage about high costs of toner carts] The inkjet-producer strategy used to be referred to as "give away the razor, sell the blades". https://en.wikipedia.org/wiki/Razor_and_blades_model includes a reference to "printers". Re: Advice on All-in-One color Laser Printer I have two color laser AIO's which I never use. Paid several tens of dollars, used, years ago. HP CM2320blahblah, HP CM1312blahblah. Only 8 X 11 flatbed scanner. But nice color. Used color carts abound on eBay. I print in color when needed, not often in 2020. Caution: there's a hundred slightly different brands of HP color laser printers, with dozens of different toner carts. Some carts are quite small, you need four of them for color. And the carts (like the inkjet ink tubs) have smart-chips in them which tell the printer "throw this cartridge out when it's half empty". Solution: buy copied chips that say "I'm full, use me up!". Change the chips, not the toner cart. And I have some refilling supplies too. This is what it takes these days, to keep from throwing money at computer-printer companies. Inkjet ink, they say, is the most expensive liquid in the world. I have to jam microcontrollers *into toner carts* to get full use of them. And use decades-old tech, to save money and get reliability and repairability. Surprisingly, this doesn't bother me much. again: we are back on topic. Regards, Herb Johnson -- Herbert R.

They tend to dry up and clog up the printer heads I'm told. I had success with ink jet printers for years, but the current one that I have went kaput. Like many things, the quality has gone down and there is no support after the warranty is done. And it was two of the same identical model (HP PhotoSmart 6520). So it's clogged and I couldn't unclog using a particular method. So I asked someone who repairs printers and they recommended laser printers. They said that inkjet have the problem with clogged printer heads. So I'm not really looking for inkjet anymore as I can see that the printer head gets clogged and repairing isn't worth it. I'm not going to buy inkjet anymore as repairing isn't worth it and it seems weird to keep buying new ones when the ink runs out.

Debugging with NMI on the PC
by Richard Cini 11 Jun '20

11 Jun '20

All – I’m working on an S100 project with my Gazelle (a VGA board) which is based on a standard Trident VGA chip. The BIOS on the video board relies on a PC BIOS (which doesn’t exist for the Gazelle) so I’ve had to hack something together for it to make it work. The BIOS is barfing somewhere in the initialization, but it’s a hard crash so resetting it to regain control destroys the context. I’m running under MSDOS 2.01. I remember that there were debuggers like Periscope or SoftICE that could trap NMI, but I need it to be pure character-based like MS-DOS debug. Does anyone know of any debuggers like this? There was one by Paul Vojta, which I have the code for, but that doesn’t trap NMI. I wonder if I could just have the NMI call INT 03H (debug break) since they all trap that. Any thoughts or help appreciated. Thanks! Rich -- Rich Cini http://www.classiccmp.org/cini http://www.classiccmp.org/altair32

OT: Video cards for small form factor PCS
by Jeffrey Brace 10 Jun '20

10 Jun '20

I have 3 or 4 PCs that I bought used for $20 each that have no GPU (video card). They are small form factor so the video cards from my old desktops don't work (too big). So I'm looking for used GPUs that I can put in them. The main use is for number crunching for Folding At Home & Covid-19 research. If anyone has some that will work with Windows 10 and HP Elite 8300 i5 machines, please let me know. I prefer free, but would pay like $20 each for them as long as they are known working. Or if you know of a reputable source for them. Let me know as well. -- ========================================= Jeff Brace Vice President & Board Member, VCF East Showrunner Vintage Computer Federation http://www.vcfed.org/ jeffrey(a)vcfed.org

Virutual VCF West 2020 - call for exhibitors, instructor, speakers
by Jeffrey Brace 09 Jun '20

09 Jun '20

Anyone interested in exhibiting, being a class instructor or being a speaker can send a message to erik(a)vcfed.org. This is open to anyone in the world. If you have any suggestions for speakers, etc. please let Erik or myself know. Feel free to ask me any questions, make comments or give me suggestions: jeffrey(a)vcfed.org. Here is Erik Klein's blurb about the show: Since it appears that we won’t be allowed to host “large gatherings” in the state of California for the foreseeable future, it is time to plan for keeping the spirit of VCF West alive without the physical gathering. To do that we want to host the same basic format. Exhibits, speakers and classes along with the “social” aspects of getting hobbyists together. The only way to effectively do that is to put as much of the effort in advance as possible. That means that contributors are being asked to “virtualize” their contributions with shareable videos, slide shows, etc. Speakers and class trainers as well as any exhibitors willing will be asked to allow for an online Q&A session after the video is aired. We will also host virtual meetups throughout the day, hopefully with special guests encouraged to visit at predetermined times. The entire event will be scheduled for 6-8 hours on Saturday August 1st with all of the videos due by July 1. What we will need: Committed exhibitors to produce 5 minute (+/-) videos of the systems(s) they would have liked to exhibit. These should be submitted to the VCF West team by early July, at the latest. Sooner is always better! At least a couple of keynote speakers willing to do 30 minute recorded talks and willing to host a Q&A Hangouts/Meetings call. Hopefully a classroom teacher or two to do a training video of 15-30 minutes and willing to host a Q&A Hangouts/Meetings call. Again if you would like to participate in one of the above categories (exhibitor, presenter, educator) please let me (erik(a)vcfed.org) know as early as possible and please get your video done as quickly as possible. Some video suggestions: Please have your recording device in Landscape mode. Introduce yourself and your exhibit to start. Please ensure that you have appropriate lighting for your video. Remember that different parts of the video may need different lighting. Filming screens is usually done in a darker environment while speakers should find as much light as possible. Audio is just as important as video. Consider an external microphone, if possible. Find a suitable space to do the recording with a minimum of ambient noise, echo, etc. If you are speaking while in the video please speak into the camera rather than while looking away, if at all possible. Play back your work and make sure you like it before submitting it! Our editors will clean up some stuff, but we can’t add things that aren’t there, etc. I created a sample video. My raw one is here: https://youtu.be/amSyI3t6JWk The cleaned up version is here: https://youtu.be/_1GKSVyuLRk -- ========================================= Jeff Brace Vice President & Board Member, VCF East Showrunner Vintage Computer Federation http://www.vcfed.org/ jeffrey(a)vcfed.org
