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

I have had one of these (slightly older model) for 15 years. It does not work as well as it once did, but for home use it's good enough. I had to replace the developer a few years ago, but it was never quite the same since.

I literally Just got the Brother MFC-3770cdw. Prints fine so far, and scanner works fairly fast. Also have it hooked up scanning to a nas. It did seem to take a while printing via airprint, but I had a power outage that I think goofed up something on my wifi, so not sure if it was the printer or my wifi. Downside is the firmware looks like it was written by a first year comp sci student, very crude compared to an HP, but it works.

I will throw in a recommendation for Samsung printers. I bought a small cheap B&W laser in 2010, still going strong and consumables are cheap if you go for the non Samsung replacements. My test for the printer when I first got it was to print the manuals for a Tektronix 7854. The only gripe I have is the paper tray is smaller then I would like but for less then $70 new, can’t complain. But you can’t go wrong with a big HP either, especially one with 11x17 capability, great for printing out schematics.
