Stefan A It's one of the many benefits of exercise, staying aggressively active and fit. I'm 58 and look nowhere close to it. Some part of it has to be genetics (my dad still looks great in his 80's), and another part has to be avoiding stupid eating (easy on the carbs, avoid processed food), but the rest is absolutely dominated by the contribution of staying fit. It was a chore for me until I started triathlon, now it is a joy that defines my lifestyle.

Oh, man, does that bring back memories. When I was a freshly minted embedded real-time software engineer in the mid '80's I was immediately tasked with programming all the GALs and PALs (using PALASM), since that "felt like software" to the old-school EEs (who were still transitioning to PC-based schematic capture). But that work sharpened my digital hardware skills, and got me deeply invested in moving functionality back and forth across the hardware/software divide, to get the most done with the smallest board and the least power consumption. Now we live in a wonderland for embedded design that ranges from discrete jelly-bean logic, to immense FPGAs, to low-power multi-core SoCs that include a shocking number of peripherals and application-programmable GPUs. Whew, what a ride!

I don't care about the totally obsolete Linux versions going yellow though. Some stuff I am NEVER going to use like Red Hat 3 or slackware or like 1994 Corel draw or something, so I don't know why I keep it. One pretty cool program came with like a Sound Galaxy card, voyetra midi studio or something. When I got to win7 none of it descendants would work, so I found a Japanese program that does the same things mostly. Also I use 'kxproject' for my Audigy2, and the synth implementation does not work properly in win7, so I got some sort of soft synth with loadable soundfonts to mimic the former ability. The kx days are ending because the end of the emu 10k chips, but I have like sound dsp flowchart conifgs for different things I am using my computer for. Very nice to use...

The whole mess was wire wrapped and on several cards in a rack card cage. I was in the last few years of a BSEE degree at the time. I finally graduated in 1980 after taking a final 400 level math course. Anyway, I entered it in the IEEE student paper contest and won third place. Thanks for all your great videos.

mos 6510 don't use tungsten carbide unless you've got a super steady drill press or CNC machine. They snap at the drop of an eyelash!! Even with a drill press, if the PCB moves sideways slightly, they are likely to snap. Go HSS all the way for hand drilling. But you'll need to sharpen them quite often. Like every 100 holes. The glass fibre is very abrasive to the HSS. A simple jig/holder can be made to sharpen drill bits down to 0mm. I saw it in a magazine once. Haven't searched for it on the information superhighway yet. Good stuff!

Long time ago i bought a Motorola DSP EVM56k board, it was great but the software runns in DOS native only (no dosbox!) up to 5.x so you would need an old PC just for this board;) it was also very famous that days, even prof. synthesizers uses these boards...

TP7 still works great if you create or find a CRT unit replacement.

You can still do it the old schematic way, I've experimented with that in Xilinx and Altera tools - it still works.

Dave, you rock buddy. I have a question: I've tried several methods of PCB fabrication for second builds of circuits, and I don't know what's best. I usually build a prototype on perfboard, but the more stuff I make, the more often perfboard doesn't cut it. For a second build I always want to have a decent layout on a copper clad board, but I am afraid to design the layout and have it shipped off the be made by a PCB house because if I mess up the design I will have wasted my money. Basically I am curious what the best method of home PCB fabrication would be. I might be able to build a hobbyist CNC mill if that's the best way. I've tried drawing PCB designs with sharpie and then etching with ferric chloride or cuprous chloride/hydrogen peroxide, but the results have always totally failed for me. I don't have a decent printer, so I haven't tried printing iron on mask resist, but I've heard mixed opinions on that method as well. Any advice? Should I just work with a PCB fabrication house, and learn from my mistakes if I make any? I only design simple stuff like analog guitar effects pedals right now with big through hole parts, so my traces are pretty big, and I usually only use dual and single opamps in different configurations, but eventually I want to do much more.

Justin Hall I make my boards using toner transfer and toner reactive foil. I use a laminator to do the transfer. I can easily get 10 mil traces using that. I drill the holes with a cheap drill press, but I use surface mount parts where I can. If I had the money, I would get a cnc mill though. It is a pain to hand drill a lot of holes and line up both sides of the board.

Justin Hall You can get access to a laser printer cheaply by going to your local library or even a stationary store like Office Depot. When considering whether it's worth it to send off a circuit to a PCB fabricator, consider the value of the time it would take you to do it yourself. It's tempting to value your 'free' time at zero, but don't do that. Even if you are doing nothing, you are 'spending' your time. Time _is_ money and just like money you can spend it developing an asset or spend it acquiring a liability or you could just give it away. Unlike money, you cannot store it or multiply it and its value doesn't decrease with inflation. ;) So enjoy your time while you have it and spend your money as soon as you can in order to beat inflation.

We still have TDS 210s in my school. Just in the basics lab, so the students don't destroy the more expensive ones right away.

When my father died we was going thru his things and we found old electronic drawings from the 1960's witch he made when he was studying on the university. It was fun to look at since I have studied electronics as well.
