Introduced C# generics (which appeared in 2005) to a code base that predates them.

Today I replaced the optical drive in my 2013 vintage IVB i7 Vaio laptop. Somehow I managed to get a working BD-RE drive for $13 on Amazon. Used, of course, though it hardly looked used. I am going to try installing XP on it but I am skeptical whether that drive will work in XP. But the DGPU is a 7650M so that should work. I upgraded a HP Pavillion with an A6-5200 to 8GB RAM. It is definitely no good for XP since there are no graphics drivers. Instead, I will probably install Linux to use for retro emulation.

But the real fun was building my first ever PIII today:
PIII Coppermine 450/512/100 SL3CC
intel SE440BX2
Toshiba 2x64MB PC100 SDRAM
Asus GeForce 4 MX420 64MB V8170SE
Creative Labs SB16 CT4740 PCI
Western Digital Caviar 80GB ATA-100 7200RPM HDD WD800JB
HL 48x CD-ROM GCR-8481B
3.5" Floppy (I was lazy and didn't bother to look at it)
Antec 250W ATX PSU PP-253x
DOS 6.22/Windows 98SE
Dell 15" TFT XGA Monitor E151FPb
Gravis Blackhawk Flight Stick

This will be my go-to for playing many late '90s games, including flight sims such as Combat Flight Simulator, Crimson Skies, Air Warrior III, EF2000 and various Janes titles.

Your coppermine is a katmai.

Not very warm out here in October, around 10 degrees C, but still quite sunny, so I decided to try out retrobrighting for the first time. Got some 12% salon peroxide for my yellowest AT panel and left it out for 5 hours. Still needs more, especially for the sides, but Im quite pleased with the results.

Opened the "going nowhere" web browser on a P4 HT 3.0 and watched Boobtube videos about repairing Amiga computer systems.

Why you ask?

Because I can I answered.

Heads exploding.

Fuck Father Christmas!

Look what I found inside my COMDLG32.DLL file for Windows 2000 (see pic)

C7 45 F0 03 00 00 00

This instruction sets the default file listing type in the open/save dialog window. I changed the '3' to a '4' and now when I go to open a file it will always come up with the "Details" view without me having to select it from the dropdown everytime!!

Yes it is. I also have a couple of Coppermine 750s and I got mixed up since it was late. I will be trying the 750 in this machine too at some point.

Soldered a 100-ohm resistor between the second and third pin of a power fan connector on a HP socket 370 motherboard, which was giving me FAN error on bootup. It worked. No fan errors anymore. I found the info for this online. The soldering job is only a quick fix, just to see if the problem is solved. I will have to desolder it again and put some heat shrinking tubes on the resistor leads.

Installed Win XP and Win 7 Sp1 on a 939 platform.
Friends need help and Doom over null modem to complete such tasks 😀

Not only that, Early compaq computers with 3 or 4 wire fans (they were not PWM nor speed) including Dell with 3 wire fans, used pulled down to ground if good, will go floating high to indicate fan fault, and lot of HP used pulled down to ground feature on USB, front panel and any fans. If disconnected HP indicates feature unplugged error. For HP, easy to identify by a small loop of wire on the plugs.

Cheers,

I cut away Apple's equivalent of the CMOS battery from one of my Macintosh SEs today, because unfortunately in both my units they're soldered on instead of socketed. I was surprised to find that after 35 years it's still giving about 2.8V.

Next up is my other unit, which I will also try to give the maximum of 4MB of memory. The SIMMs I have should be okay latency-wise but let's see how picky these machines are.

Tested a 3650 AGP.
Good for old games. Drivers are death to find and install, SDI is there for a reason 😀

I finally got around to testing my newly built high end XP system with an age appropriate game. Went through my stack of games and settled on Need For Speed Pro Street. It's equally terrible and satisfying as I spent a whole lot of time in my 20s playing that game. It's good enough to make sure there are no issues with the graphics card. I'd be lying if I said I didn't get in a few good drag races though. 🤣

Also began the process of creating an nLite XP install so I can reinstall a slimmer version of the OS now. Forgot how much time it takes to go through all the options.

Work on my Win98/DOS PC continues on a familiar path:

First I realized the motherboard had 20pin power connector and the PSU had 24pin -> two weeks of waiting for an adapter
Once the adapter arrived and I could turn the PC on it turned out that the CD drive was busted -> two weeks of waiting for a replacement
Then after the CD drive arrived, a working one this time, I could install Win98SE and then it turned out the SBLive! was busted -> off to find another sound card 😖

At least the busted hardware have been all cheap easily replaced ones, everything important seems to work just fine, including both of my Voodoo 3 cards.

Started working on videos for #DOSCember....I guess.

Fixed the 286. Adaptec SCSI Controller was dead, so I slapped in the original MIO-400 Diamond Flower Multi I/O Card, and put on a 328MB 2.5" HDD from my old NEC Versas (which have 80GB Drives now) for the drive C:\. Fixed some hardware conflicts and did some tuning along the way.

Popped open the Versa Dock last night and found out that the reason it won't power on is two high voltage resistors in the power supply overheated and cooked themselves from the inside out. So that's some more footage I've taken.

Finally got some inspiration to mount this arduino controlled "character eating pac-man" display. It had no controller when I got this Silverstone case so something had to be done...luckily some code was easy to find. I connected it with USB cable so that it can be removed (or arduino reflashed) when I get bored.

Also tried out Celebris XL 590 (dual Pentium 133). It has Windows NT 4.0 installed, I haven't used that OS for about 20 years. At first it ran dead slow. BIOS serrings were on defaults, f.ex disabled external cache. After corrected it runs just fine. Tray load CD-ROM and hard drive are SCSI.

I've never seen one of those before! Any pictures of the inside?

According to the service guide they can be upgraded to an Alpha. I imagine the Alpha CPU card is probably next to impossible to find today though.

5 hours? Two days ??

Has MS crippled their servers for Win7 or are you using a dial up modem there, even if this is vogons it's still ok to use modern conveniences occasionally 😉

Some updates conflict with other updates so I have to restart and recheck updates repeatedly. Downloading doesn't take much time; installing does, as TrustedInstaller is notorious of eating up system resources (both CPU and HDD/SSD). Not to mention that I encountered error 80072EFE at the very beginning this time.

Ha, I just met this same "friend" yesterday.

In a humorous cycle of Install software, get asked for dependency updates, get the updates manually, get told I can't install them, go to my saviour Windows Update which is going to fix it all for m-80072EFE! 80072EFE! 80072EFE! ARGGGHH! this is the final straw! rips out hair! flails limbs wildly in rage, knocking system to floor!

Heh heh, well I didn't quite go that far, but it was a farcial comedy of errors and frustrations, nonetheless. Systems are complex fickle beasts, and sometimes stable working builds are a nasty pack of delicately balanced wasps just waiting to be poked.

Two long muckaround days later, and I've finally got... a slightly faster system... whose stability the jury is still out on. Win!

Here's one. Maybe I'll take better ones.

Finally disassembled the front panel of an Acer Aspire X1800 after three hours trying not to break any plastic clips -- fifteen of them!
Everything but the micro switch underneath the power button was fine; the computer is "broken" because of this tiny, cheap part that requires three hours to replace, if I could find a replacement of the same model.

You don't need an adaptor unless there's something else (e.g. a capacitor) blocking the addition 4-pin part of the 24-pin connector from PSU.
