I'm researching the history of the "tower" heatsink/fan in consumer desktops. Cooling fads have come and gone, but air tower coolers have stuck with us for about two decades. 😎

Created a Win98SE and a Win 2k VM (with all the updates and blackwingcat's kernel extension). Tried numerous browsers. Eventually gave up on Win98. Focused on Win 2k, finally got the KEx to work and installed Firefox 52.x ESR, Pale Moon 28.x, then changed desktop color and icons to look like Win 98. Youtube works now. I feel at home now. I wasted a whole weekend for that... the only thing that annoys me is the font quality in my browsers, they are not smooth.
But I feel at home. Dunno why.

Isnt the Pismo a G3 PowerBook not a G4?
On my own activities, I diassembled (and ultimatily reduced to parts) BOTH of my 2nd gen I3 powered Toshiba Laptops. One had an unobtainium keyoard that was totally fucked and a non-functional trackpad and numerous other chassis issues, and the other just didn't boot. I pulled the CPUs (both i3 2330's), RAM (all 2GB modules, 4 total 2 per laptop), Optical Drives, Hard Drives, Mounting Hardware, and the keyboard that was good and burned the chassis parts and screens (both of which had scratches). I also kept the batteries one of which is an extended 8800MaH battery. I plan to order a Toshiba of similar age since I have 2 extra batteries, and the experience with the one that worked showed it to perform half-way decently aside from the user interface devices all being FUBAR'd.
Right now I'm using the X200 Tablet as my main laptop and I LOVE this thing. It is everything a laptop should be and more. I think I might also need to pickup a Thinkpad X220 (i3 version of the X200). I love this full size 12.1 laptop/Tablet form factor. Why did this laptop form factor disappear for the stupid ultrabook 2-in-1 form factor anyways?

Was playing around with my 286 today. Not having touched QuickBasic for close to 30 years, I wondered how long it would take me to make analogue clock. Turns out, about an hour or so, had to look up a bunch of stuff I'd forgotten about. Still heaps of room for improvement. 😀

Started backing up the hard disks of my Apple Powerbooks in case they fail or get damaged by a software crash. Did the 190cs yesterday, now the 540c is running its backup.

Right now I'm using the X200 Tablet as my main laptop and I LOVE this thing. It is everything a laptop should be and more. I think I might also need to pickup a Thinkpad X220 (i3 version of the X200). I love this full size 12.1 laptop/Tablet form factor. Why did this laptop form factor disappear for the stupid ultrabook 2-in-1 form factor anyways?
It's usually a G3, but I got the Wegener G4 upgrade card, so the machine ran like a Mercury (Titanium PowerBook Rev. A) but minus that liability-of-a-chassis (the TiBooks are notorious for being fragile as they age). I kinda wished that I kept the PowerPC 750e/400MHz Processor card so I can do a comparison between the G3 and the G4, and an out-of-box, as-is comparison between the Pismo and the ThinkPad.
Oh yeah, I had an X41 Tablet - I hear ya. The twist-and-flop form factor is more comfortable to work with. That being said, that hinge is expensive to manufacture and the machine doesn't fold as thinly as the 2-in-one.

I ran Zandronum (Doom mod) on P233MMX, W98 with Yamaha pcc10xg (PCMCIA) as MIDI device. The card sounds awesome. It also makes a huge difference in terms of performance. If I switch to software Roland MIDI synth the game runs signufucantly slower, becomes unplayable. And with the Yamaha it runs smoothly, yet only in 320x200 mode.
So, delivery driver offloaded a whole pallet at my house today, the box was big enough to fit me... and inside of it were even more boxes, and inside the larger boxes were even more smaller boxes 🤣
anyways, started to get my stuff a bit organized before I drown in random hardware ^^

I was going to have stab at adding a digital clock this weekend (if I could find the time), switching between analogue and digital with F1 or something. Your clock looks great! I wasn't yet sure on how I was going to formulate the digital number segments. Maybe your code might give me an idea or two... 😀

The Pismo is even worse. I've got three and gave up trying to fix them. They have flimsy parts everywhere. The "thickness" of the plastic holding the hinges must be a bad joke by whoever designed that thing... Also what breaks easily is the part below the mouse button - and actually that whole case part, the bezel of the display, and so on.
During resurrecting a k6II-450 I suspected immediately that the PSU has not to be trusted. The voltage was ok @ empty or in mild loads, there was indeed a fault lurking. Used my "Chinezium" electronic load to test the 5V rail, and for my amusement @10A I was getting a severe undervoltage.
The psu was supposed to supply at least 20A. The undervoltage may not be a cause of catastrophic failure but in time it will degrade the dc-dc converters. So, as precaution we should always suspect this generic Chinese psu bricks, that is if we value the parts that they supply.
wrote:The psu was supposed to supply at least 20A.
Yes, combined on all 5V rails. You are not supposed to draw 10A from a single 5V rail.
This psu only has 1 rail of 5V, as its common on all Chinese AT style PSU. Usually they tend to use a pair of fast recovery diodes to form a rail. The concept of multi-rail per voltage is a tad new in cheap PSU's.
At 5A I could see a 0.5v drop, from the nominal 5V, and I suspect that the ripple would be high though I haven't tested it.

Well, it's at least plastic, so the old superglue-and-baking soda trick still works reinforcing them. What I tend to see is the screw capstans fracturing, but it's fairly rare to have to strip the Pismo down that much (short of swapping out the logic board, since almost all of the field replaceable components are easily accessible once you take the keyboard out). The TiBooks on the other hand? The titanium frame distorts until it fractures, and whatever Apple used to coat them flakes off and they look rather terrible afterwards.
Of course when it came to durability, nothing beats a clamshell/Toilet cover iBook. Those things are made with PVC...
