It shouldn't be too hard to make something alike again, also another option is to have the second one with sockets on the other side of the PCB, which wouldn't require making it taller.

[@Toxis374]

1:35 The funny thing is that today, a used and working 72-pin SIMM module is cheaper to buy than one of those 'SIMMverters'. 4:31 Putting a module into a socket with those metal clips is just such a satisfying task. All those modern flimsy solutions are nothing compared them. 4:50 Those selectors are called the presence detect, retroactively called parallel (PPD) to distinguish them from the modern solutions which actually use a ROM that is read in a serial fashion (SPD). You are right saying that the PPD is not used anymore on later motherboards as they automatically detect the size of the RAM. However, they cannot detect the speed of the modules, so those boards typically provide a way to set up the speed (if they are not designed to work with one speed only anyway), the most modern ones even went as far and allowed to set it up in the CMOS Setup. 10:15 I have made the experience that the tin-plated contacts of those memory modules are notorious for making bad contacts, especially because they are usually old and had some nice time to build up an oxide layer. 31:50 The moment when the viewer already sees that big fat scratch on the upper side of the second platter and Adrian is still guessing 😁

[@00Skyfox]

I recently had a 500GB Seagate drive that had a catastrophic failure that my computer tech friend had never seen before. In the middle of the night the bearing seized up so hard and so suddenly, the rotational momentum of the platters snapped the spindle shaft right off. The motor continued trying to spin what was left, and it woke me up making one hell of a racket. Until that point it had been a very reliable drive over the previous 13 years or so.

[@michaelmichalski4588]

I remember these from back in the day. They had a few drawbacks. First, being so tall it was easy to break sockets with them. They also had compatibility issues which were usually said to be due to memory timing. There was not a lot of discussion on the jumpers so that may have been an issue as well. The biggest issue was they tended to be comparatively expensive, offsetting the savings. As an alternative, there were a few companies that claimed to be able to take the chips off your 30 pin sims and put them on 72 pin boards.

That platter damage looks exactly like what I expected. The second you turned on that drive I cringed and said OOOF that drive is GRINDING off the surface.

[@ltsiver]

In one of Steve Gibson's old tangents on his security now show, he mentioned the phenomena you mentioned on old (and current) hard disks - it's called Sticktion. It's what happens when the head instead of riding above the platter, sticks to it. and on the older drives, it rips the heads right off on spinup. (Steve Gibson, creator of the apple light pen and hard drive software Spinrite, at grc dot com)

[@Renville80]

Regarding the unhappy drive, I’m reminded of an incident at a previous job. We had a test bench that had an ancient IBM XT running the equipment on this automated system, and one day, one of the techs was checking out something at the bench when he heard a loud *CLANG* and the IBM stopped working. He was momentarily confused by the noise as he thought something had fallen off the bench onto the floor, it was that loud. He soon realized the computer was down, and some checking revealed the drive had pretty much “thrown a rod”. The dead PC was sent back to the customer who was cheap enough to send over a cobbled together from spare parts PC as a replacement. At least we got to retire the 5 1/4” drive we used to ‘sneakernet’ the test results to the main network in favor of a then modern 3 1/2” drive.

for the PCJr i think one could make a basic PCB, 3D print a cartridge and insert it on the slot, with a button protruding from the front! So the reset button can still be there in the front, but no need to drill the case front or back!

[@MatthewPiercey]

That'd be a cool idea for sure! Maybe one version could just sit flush with the button on the front, and another could be a larger port extender that pops all the way out, has a button on the side, and lets you still put a cartridge in that slot. Obviously the first one would be more practical, though.

It sounds like the adaptor for the mouse is changing timing or acting as some kind of buffer. Apple, at the time, had different chip suppliers and there could be buffering or timing issues between versions of the same mouse, even if they had the same shape and same model number. As a few others have said, you take a lot more time on unboxing than most channels that do unboxing care to do. It does make these more special. As a note, I always get notifications of your vidoes.

Actually Simverters were not only available ready to use, but also PCB only (if you have the soldering skills to desolder the sockets from an old defective board). PCB only was quite cheap. I got a board with 30-pin sockets at a time the old 30-pin memory cost more than 3 times so much as the 72-pin ones. I used the Simverter PCB the other way around. I soldered a 72pin socket to the end of the PCB and pinheaders on the position where normaly the 30-pin sockets should go. the pinheaders I soldered directly into the 30pin sockets on the board. So I was able to connect a 72-pin ram on a board with 4 30pin sockets - and it worked well.

Trace length became an issue and prevented tighter timings from being reliably used. For a 100+ mhz Pentium or equivalent AMD or Cyrix CPUs you needed to use EDO 72 pin SIMMs for best performance, especially if you were doing any sort of overclocking or adjusting the FSB above 60 or 66 mhz.
