Slight upgrade. Bezel swap.

Matter of personal preference, but I like the looks of the top bezel better.

So do I.

I alao want the case/sezel he doesnt use 😁

Except the "tossing it" part. What a waste. Personally, I find it rewarding bringing old hardware back to life and getting it into the hands of people who appreciate the historical value. It is why a large amount of my collection (rare games, restored consoles, etc.) went to reputable museums. I downsized to just a few things I am either restoring or enjoy actively using.

Got myself a copy of Vol 1 Issue 1 of Maximum PC. I got a whole bunch more too from around 2004 and 2013. I max not see daylight for months.

Soldered on a new potentiometer for my Aztech Sound Galaxy NX Pro successfully and it lives again! With the old pot off due to rust and oxidation, the volume was too low, and now, I get full sound. I also reinstalled the drivers in Windows for Workgroups 3.11 and MS-DOS, and it's a big success. Not sure if a car counts or not, but I solved the bleeding brake of doom on my dad's 05 Chevy Malibu Maxx LS by removing the brake line screw and putting it back on. All I need to do is bleed the brakes out, put some new fluid in, smoke drive it to see if it'll resolve the issues, and violà

Also hooked up my external ZIP 100 drive to my Packard Bell, and the tools program doesn't see the drive (mainly because I don't have a ZIP disk at all). Going to get 20 of them and about 12 DC 2120XL data tapes as well. Gotta love having 2 backup drives on 1 system, just in case.

I decided to start with my 486 build. I have 5 486 motherboards, but choosing is difficult. A few have battery corrosion, fake cache, etc. Will post a separate thread for that build I think. I did remove the Dallas RTC chip on one of those 486 mainboards and installed a socket for a new one. I damaged the old one unfortunately, so I won't be able to mod that one with a battery holder. The board seems to work fine now with a new Dallas RTC. Will power on tonight to check if it held it's settings.

Nice, socketed RTC. Some of them are soldered on

This one was soldered on, but I desoldered it and put in a socket 😀

Gave my two Pentium MMX CPUs (200MHz and 133MHz) an OC test to see if they can hit the magical 300MHz mark.

The 200Mhz one went up to 250MHz (2.5x100) at stock voltage and remained stable throughout a bunch of game tests. Beyond that, nothing I did, even setting the voltage to 3.2V could make it even POST.

Next up I tried the 133MHz one. The stock clock might have been low, however it was from a laptop and was supposed to run on 2.45V. I didn't waste time on lower voltages and lower clock speeds and I went straight to 3.2 and 300 MHZ (3x100). It would load up Windows, but sadly crash during tests. Same with 3x95.

A 300mhz mmx is a sweet deal - mine went to 275 and then it was over... your 133 chip was quite the warrior.
Guess the only option is to "quantity buy" and then test.

What's the advantage vs say a Pentium II 250?

Huh. A laptop Pentium MMX 133 in a desktop computer? Interesting. Or am I wrong?

Never knew that's possible, and it looked like the CPUs in the laptops past the Pentium 1 with MMX used different sockets in the systems than the desktops did.

This one was just a plain S7 from a Medion laptop. The wikipedia page shows Tillamook in a different package so it could be they started using different sockets from there.

Went to see if I had a Settlers 1 disk, but ran into my SimCity disks instead. Turned out I have 2 versions of SimCity, but both seem to be early DOS versions. Browsed through both the disks (2 different copies of what is apparently the DOS version of that game) and alas, seems I get no fancier graphics for SimCity. The fancier graphics reminded me a lot of the SNES version of the game btw.

That's like comparing apples and pears. But to answer your question (apart from bragging rights), the advantage is that the 300MHz Pentium 1 MMX is on an older platform, on the Socket 7 platform. They are different, Slot 1 and s7 are different.
And a 300MHz Socket 7 chip made by Intel is interesting in itself 😀

Imagine if Intel did release the original Celeron (the one that didn't have L2 cache) for socket 7. That'd be rather interesting imo ^^

Who know, maybe they intended this at first so no integrated L2 cache wouldn't have been a huge deal like it became ?

Disassembled my Roland SC 155 and sure enough, the battery was leaking. Luckily these batteries do not seem to be corrosive.

Finally got around to installing FastVoodoo 4.6 drivers on my SLI system and the mismatched cards work perfectly.

Well, sort of.

They work perfectly at 640x480 and 1024x768 but at 800x600 everything has a red-ish hue.

Strangely enough, even the id logo intro of Quake 2 seems to suffer from the issue when launched with the -gl_mode 4 parameter.

No idea why, it might be some quirk with the TV it is connected to, I suppose. As far as I'm concerned, this is a success. Playing Quake 2 on an MMX at 1024x768? Checked and off my bucket list..

Try installing the overclock util. I bet it is running at some 93/95mhz.
Try setting it to 90 and test. Lower it by 1, for each test.

Replaced the OnTrack Disk Manager overlay on my EGA build with the XT-IDE BIOS on a NIC. Had to repartition the drive and install DOS again (the rest of the files were restored with the help of mTCP's ftpserver) but in the end it was worth it since the system now has ~612kb of free conventional memory. The extra memory range needed for the XT-IDE BIOS borked the UMB driver for this old mobo (meaning no safe-to-use UMBs anymore) but it was still a good trade-off as the UMB driver was really weird for this machine...
