Sillycon die layouts sporting a tennis racquet in one corner have been laid out by a certain Mike from Florida.
Must see if I can find the pics he sent me.
As attached. Top left is Mikes racquet signature.
You can't play video games on the cheap office/fleet-duty monitors. If you're lucky they're good for 60hz. Even at that pitiful refresh rate, they tear and blur like crazy. You don't always get a good monitor by throwing money at the problem; but unless you win the closeout lottery, you don't get good without paying a fair bit for it. Same is true of most TVs... they make horrible monitors in most cases, even for game consoles.

moo. or don't.
Maybe I worded that badly last night, I haven't played any really modern PC games, the last PC game I tried was a version of Sega rally, this gave the motion sickness problem on the 24" Samsuck LandfillMaster monitor, that came new with a PC I had built about 15 years ago. A free game some years later had the same effect, as did an update to the MMORPG (aka time-sponge) I played on & off for many years (thankfully there was a option to disable the camera shake effect in that). Youtube videos where no gimbal or imagine stabilisation was used, can have the same effect, as I mentioned some TV programmes & films can have this shit forced on you too.
I can only view or play for a short time (say 10mins) before it becomes a potential vomit problem.
I never had this problem with the various 14" port-a-bile CRT based TVs and numerous game consoles I have (Dreamcast, Xbox, Gamecube & Wii). The Wii was the second last one I bought, Nintendo turned evil & blocked the Gamecube code disc, bastards, therefore I ended up buying a second hand Gamecube to carry on with the older games, I completely lost interest in consoles soon after that.
No one else in family seems to get motion sickness problem with screens, it's just me.
I've no need or space for anything larger than the 24" monitor, anything in this size or smaller seems to be low quality shite these days, for both TVs & monitors. I'll be using the repaired LandfillMaster till it dies completely, will probably go with dumpster find or cheap used monitors then.
Still haven't replaced the GPU due to overpriced cards, following the chipageddon shortages, the only game I really want to play is Shenmue III, maybe need to bring a CRT monitor back from storage.

No, I get you... I had the same problem with every VR headset I ever tried up to the Oculus DK2 with 90Hz OLED display. Just minutes and
. I tried a prerelease DK2 at
PAX jeebus...10 years ago maybe? Immediately signed up and got mine about 6-7 months later. That display was a game changer; tho it wasn't until like the 3rd go-round of FW updates that the fringe-ghosting was cured to the point it didn't make my eyes
bleed cry involuntarily.
This is also why I've always advised fellow gamers to spend mostly on the GPU and the display... those are the big investments; dig deep, until it hurts. Skimp on RAM and CPU if need be; those can be upgraded much less painfully and then the old flipped for a much better share of what you paid.

On the annual suspension renovation subject, the car's now been supplied with new front ABS rings, new front right sensor, new front control arms, and been bolted together and test driven. Both ABS and traction control improved back to working, and handling also restored.
Remaining are rear shocks and springs, oil change and MOT.

"Dominy, Dominy, Dominae... grace of God go with you my son on all your travels... may you return with a clean MOT and enough money left over for a cold one at the pub on your way home."
At which point he'd have a bigger cost, the drink driving fine. Sweden's BAC limit is 0.02%, which is the rough equivalent of drinking a 1/4 pint (imperial) of beer. So no cold one on the way home from doing anything in the car.

Yup. One needs to be careful. Not all are. We recently tailed an US-import pickup truck all over the road while talking to the police because it was driven most likely under influence. We reported where the driver stopped and got out. Another time I sat in a traffic jam and watched, to my horror how a bottle was passed between driver and passenger in the car behind me. Also had a long conversation with the police on that, reporting things as when they were opening a new bottle et c. In the end the police encouraged me to carefully follow it to establish where they went; I tried but did not want to break as many rules as they did..
Even before I got this far down the thread I'd remembered that there was a thing for a while of taking the caps off ceramic packaged CMOS DRAM and using them as camera sensors. Saw one on a BBC micro once. A web search turned this up

Mind you back then a 64k DRAM chip wasn't cheap.

Yes we had one of those at my school which was discarded. Think it was Beebug or WE branded. I wrote a motion detector using pixel averaging for it in BBC BASIC with a little bit of 6502 assembly. It wasn't much use for anything else
Circa 1982-83 shot of bd139 at work on a fresh beeb . My poor father never got near it.
Where did all that hair go...
Heh, I know that feeling. Also 1983, a still from one of my rare acting appearances:
That's me on the left* with, yes, lots of hair.
*Kind of obviously if you recognise the other two and know I'm a bloke.
New York airshow. 3 years ago. Most recent pix I have. Hair present then. Hair present now.
Wow looks beautiful.. must have cost a fortune to assemble/manufacture !
If you like to watch pictures of semiconductor dies, then you should check out Richis Lab.
Here is an example from a Motorola 2N3055 transistor. What I really like about those pictures about power transistors is that one can see the barrier layer, because Richi is driving them in reverse mode and then the B-E diode becomes a Zener.
B-E diode working as a Zener at 300mA:
OK just sacrificed a 2N3055 and tried the same experiment. Doesn't work, die doesn't light up. VERY disappointed !
Maybe it can't be seen with the naked eye, or it needs a long exposure time to gather sufficient light, or it requires a special version of the 2N3055, I don't know.
All I can say it that it didn't work on my particular transistor, and I now have one less 2N3055, he died for nothing. I am sad now.
I have to correct myself regarding the B-E diode is becoming a Zener. This is only partially true. The main effect is, that the B-E diode is working in avalanche mode. Depending on the materials being used, the produced light can be anything from IR to blue (SiC for example). Richi states, that the light can be visible to the naked eye, but it is mostly very dim. So, if you want to see this effect, it is perhaps a good idea to sit in a dark room for about 10 minutes so your eyes can adapt to the darkness and then try again.
Here is a discussion about the glowing effect of B-E diodes working in avalanche mode:

https://www.tradera.com/item/340198/542487628/spectrumalalysator-tektronix-7613 purports to offer a 7613 mainframe with a 7L3 SA. It's being sold as faulty, and will need repair. Some of the powered up pics are possible clues to the fault, but I know next to nothing about the 7000 series. Seller states "HV present, but the rest does not work so well. For starters, a liberal amount of contact cleaner will be required." The price is interesting, even if it will go up 100x, but I'd like some opinions on possible faults, so I know if it's worth fighting for.

Choose wisely. It is both rewarding and hell equally so. And that's just the SA plugin. The mainframe, being storage, is likely to require a lot of cleaning and a whole bunch of new caps.
And yes, I would buy it.

It looks like flood gun store mode is working as indicated by the bright screen. But there is no trace. That could be anything as a possibly as simple as the trigger set to "Normal" rather than "Auto".
It's a tough call.
Edit...I have a non storage but similar 7603N and re-capping the PSU was a beast. Getting to old cans off the circuit board required cutting.

Wow... way to murder a joke.
The whole notion of a clergyman... err, dwagon... suggesting a drink on the way home... that was like
the joke. He would suggest such a thing because it is the
draconically correct thing to do.
mnem
Never said he had to be the one driving home if he did stop for a cold one, either...
From the "TODAY I..." Dept...Today I made a slack-tube manometer from bits of a brake bleeder kit because... the HVAC tech they sent out didn't have one, or even the usual low-pressure diaphragm manometer to confirm that the upstairs AC unit we have frosting up was delivering somewhere close to expected airflow at the supply plenum.

ok.........picture to prove the freq once had hair. circa 1980 on the loyalsock trail in sullivan county.
my recollection is that the next morning we had to belly slide out on a pond and break a hole in the ice to get cooking water.
edit just noticed it says june 80. that must be when the film was finally developed, because the hike was probably in feb.
