The old HP stuff was wonderfully over-engineered - I've got a HP 5245M frequency counter (50MHz !) that based on the ink stamps on the chassis was made in 1969 - it still works correctly and you can go through the whole calibration procedure and everything is still in spec. I was a bit worried about all the electrolytics - they are 50 years old, after all - but when I checked them I found that although they were down to about 60-70% of their marked value there was so much design margin in the product that everything remained in spec anyway.

Sometimes when they test the dies, the yield rate is so low it's not worth chopping the wafer up to get the good ones out. It would have to be pretty bad though, something like 10% or less before it isn't worth bothering.

They repurposed some of those for a shot in The Expanse season 4! They 3D printed(?) small orange holders around each of them, and a brief shot says around the edge that it’s an encryption subsystem. It’s surely presented that way just because that’s how these come when bought from eBay (especially because the rest of the computer hardware shown are side-lit laser-etched acrylic “chips” much like in Star Trek), but I like the idea that the encryption is so complex a few centuries from now, and thusly their designs are so large, that the hardware codec has to be split across an entire bank of a dozen wafers to function. Moore’s law having physical limits, after all, and die sizes are already growing nowadays!

The 9pin on the Keyboard Encoder is for a user installed Numpad. S2 can be installed to enable quad mode encoding (4 states per key, including lowercase, CTRL, CTRL+SHIFT) but you will need a new ROM for those characters and also cut a few traces on the encoder. I don't remember how to do it exactly.

@@hi_tech_reptiles a lot of wafers get rejected. When the wafer is made they do some initial testing to look for defects, if there are too many the whole wafer is discarded before they actually cut out the individual chips for further packaging and testing as that is expensive. I'd guess the pricing depends on factors such as what chips they are (popular CPUs are probably preferred), and what kind of process (what nm feature size etc).

I saw some of these when I was taking Electrical Engineering courses in college. We were told that every single chip on the wafers were defective, so these wafers could be full of defective chips as well. I once got a key fob from IBM that was a single wafer chip embedded in clear plastic, most likely defective, but still cool to see. What is also interesting is the size of the wafers themselves. They were relatively small back then.

I actually gasped when I saw the contour of what was in that foam packaging. The HP 547A current tracer is awesome. Invaluable piece of kit. It's like magic. They are close to unobtainium by now. The 547A could be bought in a kit with the 546A logic pulser and 545A logic probe along with a few other goodies. I have that kit and the 547A tracer and the 546A pulser it a wonderful combo. You can use the pulser to inject pulses unto an unpowered board and probe around to find where the current goes. Great for finding shorted tantalums! The pulser function can be replaced with other things but the magic voodoo of the tracer is simply not manufactured anymore. The indicator light in the front assembly is actually not an LED but a small incandescent bulb. It's part of the voodoo and probably difficult to replace so be gentle with it. The 547A tracer can also be used to detect bad RAM chips. No more thumbing around for hot chips. Just probe the top of the RAM chips and compare the internal currents. I said it before but it is like magic. Can't wait to see you use it :)

The ferrite core is usually for fixing EMC issues. That means, it works in the RF range. It blocks the high frequencies from going into the keyboard cable, where they are then emitted. You have been taking care of it a long time, before us in Europe. EMC and CE certification is mandatory since 1997, here. So our C64s don’t have a ferrite core at the keyboard cable. And yes, it is good to place it as close to the mainboard as possible. The ferrite core will not improve functionality, I think, because bouncing and whatever interference happens on such a keyboard has a way lower frequency that what the core attenuates. A sensitivity to RF usually does not play a role. In all EMC tests, that I have been conducting, I have only seen it once, that was with a capacitive button UI.

Aah the Soldapult. I used one of those at a previous position for several years. Technique-wise, you can hold the Soldapult in your left hand and make a fist with your finger on the button, soldering iron in your right hand as normal. Slam the spring plunger against your left thigh to arm the unit, then twist your wrist to put it up to the work-piece and push the trigger. With a little practice, you can desolder an entire 10-pin IEC connector in under a minute. The next upgrade is either a Hakko 808 for around US$200, or a vintage Weller WR3000 for US$2000+

Hey Adrian! Thanks for the hint with the high quality mechanical solder pump! :) One piece of advice about mechanical solder pumps: Not sure if you do that already, but I noticed you have to clean them regularly by taking them apart and wiping the inner side of the piston and the rubber O-ring with isoprop to remove solder and flux residues and potentially (carefully, because solder is hot as we all know!) grease them with something like Ballistol (let's call it German WD-40) and even the cheap 2.5$ ones will last for years! I suspect even the genuine pump will degrade in performance unless it gets cleaned from time to time. I'm looking forward to testing this! Stay healthy and safe as well!

Glad to see you got one of those solder suckers. They work real well, but you do need to clean them regularly, including the face of the plunger, as the solder will eventually build up into a disc you can just pry off. There is definitely a technique when it comes to using it. A quick way to reload the unit is to push the plunger with the heel of your other hand (yes, the hand currently holding the iron), but once you get the hang of it, sipping out solder will go fast.

Keep in mind that the same die can be used in multiple EPROMs. They might wire up a higher capacity as a lower capacity if there was a defect in the unused part of it, but the part number would not correspond.

So lucky. I've been wanting one of those HP's for the longest time. Would have been great during my last repair

I have a - you could say - bootleg copy of the Soldapullt. It was just 30 cents more than the cheapest model but it is awesome, works several orders of magnitude better and lasts a lot longer. The only reason I had to buy another one is because I mislaid / lost the first one.

You can't just pull out "the towel" without verbally acknowledging the towel and it's aesthetic.

Those HP probes came in a few variants, Years ago 'we' dispatched a few logic probe variants to techs at a telephone exchange. A few weeks later we heard them say 'they went off like shotgun cartridges'. The twit didn't notice the decimal point between the '5' and the '0' on the label, and read it as '50V' then promptly connected them to the 48V supply of the phone exchange. The poor HP probe complained violently to the gross over voltage..... What a waste.

Those big-blue solder suckers are amazing (there are several clones too, which may be unlicensed). One thing to keep in mind is that the piston and gasket needs to be cleaned and lubricated regularly. The tool's advantage is its large spring and "sucking power"; when the piston and gasket gets jammed with solder, the suction power is greatly diminished.

Thanks Steve -- yeah I will be ordering a couple parts to service it -- and remember to clean it out and lubricate things periodically.

my cheapy solder sucker is identical to yours. all I had to do to mine to get it working excellently was pull it apart and put a lick of silicone grease on the piston's sealing o-ring.

My II plus I just finished working on has that other keyboard type. Luckily my friend had a spare keyboard, because if those stems break, theyre unobtanium. Really would like to start 3D printing replacements, but I don't have the know-how. Also helpful to see another one of those keyboards, I thought my space bar was upside down but yours is the same way!

Those definitely look like real silicon wafers to me. My dad worked at Motorola years ago and he brought some home from time to time that were defective/unusable. I sadly don't have any of them any longer but they are cool to see in person.
