Found a boxed Swiftech MCX6400-V socket 939 heatsink I had forgotten about. I never had a 939 system so I guess I bought this a decade ago intending to use it on AM2 but when it arrived the weight and density of that half-inch slab of copper put me off so I used an Akasa Venom instead. As that system is long gone I'm now vaguely pondering whether to buy a motherboard and cpu to fit it, which wouldn't make any practical sense and would subvert my attempt to declutter...so probably won't happen.

Maybe the sticker with the jumper settings fell off.
The first memory module is EDO. I am not sure about the second, looking at the date code, it looks like EDO to me. SIS 471 is FPM only. It might POST with EDO but you really need FPM memory.

Stuck a few more cards into my slot A machine: PCX2 works (driver installs), CT4760 was a real pain until I got the right drivers from vogonsdrivers and deleted all the crap that my Live 1024 CD had installed. I've never used a Live! before (this was bought s/h and stored just so I had one) and only used an Audigy pretty briefly - always used a Santa Cruz or Aureal once we went PCI as I wasn't impressed with the SB128PCI.

Gave up on my Sound Forte 16, the jumpers aren't silkscreened, maybe I used something from stason.org for a similar card. It used to work and sounded clean with no hanging note bug coompared to a Creative SB16 (it has Creative chips like CT1745, and an OPL3). But Windows doesn't detect it, SB16 drivers don't work (I was sure that was what I used before)... could be a conflict I guess. And I can't remember how to set up an SB16 and cba to loo it up now. Something for a rainy day.

Aw I dug out my "spare MX300", found it was a Diamond-branded SQ2200 with a peeling Aureal sticker... turns out that is an MX300, must have known that back when.

Ah cool, odd that it lets you select the range that breaks everything since 4MHz won't do much.
85C471 should only be exposed to FPM, it will just fail to post with any EDO in my experience
That's a shame about the CPU, but isn't it a relief when swapping the CPU is actually the fix? I was troubleshooting a Toshiba Satellite 4270 the other day which wouldn't power up and reading the codes it was dropping too low on the 2v rail. I had no idea what that meant so I swapped out the CPU for another one (thank goodness this one wasn't BGA CPU) and it started right up...

Now I know how to replace the polariser on a DSTN display and get it to display its proper colours - this thing has been unusable for a few years now I think?

My Sony digital alarm clock modified decades ago, recently stopped activating the relay to get external vibrator running to wake me up from sleep. I liked this clock and was cheaper this way to modify than buy another crappy quality clock for the deaf that costs more.

Well, in this clock, installed external simple driver circuit via flying wires and few components to drive a small relay in turn via cable, activates the high current relay which completes the 115VAC circuit that drives transformer that steps down voltage to drive a vibrator motor. I picked off a signal from the clock chip that drives buzzer circuit or radio. The clock chip datasheet was fortunately found online allowed this modification to succeed.

Reason this happened recently is two filter capacitors for power rails, finally expired. Replaced these restored this!

This LED digits clock, yes now a vintage, was purchased, almost 30 years ago. Sony Dream Machine FM/AM Model ICF-C25 in black.

Cheers,

Great Northern aka Canada.

Picked up a pair of 256MB PC133 SDRAM modules. Also, recently picked up an Asus P3B-F with a P3 500 and an SB!Live5.1. Finally I am able to build my Thief/SystemShock2 dream machine.

Came back to one of my other bench builds, featuring the K7 Pro. I had remembered it was pretty bland, aside from a slightly custom theme.

To do list. Might as well get it done on Sunday 🤣.

- custom wallpaper
- custom theme
- 2k icons
- maybe lower to a Banshee from the V3 2000, idk
- MOAR GAMES.

Some specs:

- MSI K7 Pro MS-6195 (IR3)
- Athlon Thunderbird 700MHz, SLOT A
-3dfx Voodoo 3 2000 16MB AGP - been debating whether to flash it to a 3000 BIOS, but I don't have a replacement heatsink that would keep it cool enough - it gets hot as it is already.
- SB Audigy 1394 (SB0090)
- RTL8169SC Gigabit NIC
- NEC USB 2.0 card
- 40GB Seagate HDD
- LG GSA-4120B DVDRW
- 98SE

Cool, I'm using the 6167 which seems similar to yours but with 2 ISA slots (1/5/2 rather than 1/6/1), just switched from what looking like a broken Banshee to a Voodoo 3; I'm using 98 first edition. Banshee seemed a good match while it worked.

I have installed the chipset drivers but Device Manager tells me I have two DMA controllers, one that it can't install the drivers for. Do you get that?

No errors on mine aside from a leftover VXD from an failed driver install for a Aureal Vortex II that was installed there as well as a exclamation mark for Internet Connection Sharing.
I plan to get a 6167 too until winter since I have a leftover 700MHz Pluto doing nothing.

As for drivers, I'm using the MSI 2in1 drivers from the TRW page for my mainboard - you could try those and see if the errors go away.

I'm planning on buying 2 Banshees off a scrapper I know - one is a intact Magic Twinpower, the other is a AGP 3D Blaster. Hope the Magic Twinpower one works at the very least. I have a HSF combo left from a TNT2 M64 that would fit a Banshee card like a glove. The 3D Blaster, I have a few NB heatsinks I can adhere on it.

Ok, I downloaded the MS-6195 iso from there and installed a few things and deleted the DMA controllers - it's fixed now. All I have left is a BSOD on shutdown...

I need to do the same thing to the old Harman/Kardon HK-206 speakers that are plugged into the TV in this house.

I finally cleaned the volume pot in those speakers. In the tradition of being a complete moron, I missed one screw on the back, forced it apart, and broke that post off. There is some glue on the corners of the front panel, and I thought I just needed to pry them apart to separate the glue. I'm getting so weak and shaky that I didn't think I would have the strength to break plastic that thick. Then I turned power on (to make sure the pot wasn't scratchy anymore) with a bunch of screws under the board, but it didn't cause any damage. After that, I wasted half an hour trying to get them reassembled before noticing that there was a wire caught between the two enclosure pieces. How did I get so far in life? As I get older, I make more stupid mistakes, but more people think I'm a genius at the same time.

Anyway, they're working for now. I might have made it worse, considering that the pot feels rough and loose now. I've never used the "fader" Deoxit, so I didn't know that it would also wash the damping grease out (grease that specifically provides some resistance when turning the shaft) like regular Deoxit. I guess you're supposed to completely disassemble them and apply cleaner directly on the wiper and carbon track. I will probably do that with the other set of computer speakers I have, but that volume pot is probably worn beyond saving (and an oddball part that I haven't found a replacement for). I probably should have also replaced that blue Fujicon cap while I was in there, but I didn't feel like soldering today. I don't know why I left it when I did the recap in 2010, but it still has enough capacitance left to let the power LED fade out when I unplug the power at the barrel jack.

After I was done, I tested them with some Van Halen. These speakers have good bass for their size. I would take them over the usual modern computer speakers (40mm "full-range" drivers with no grille and a 4" "subwoofer" that are all in untuned enclosures, regardless of price - higher price just adds fake tweeters or DSP tricks to give the illusion of more bass for a brief moment).

So far:

- finished the wallpaper for my Slot A 3dfx build (Elizabeth Rose Bloodflame's opening screen and I think a promotional 3dfx wallpaper)
- scared myself because I accidentally touched one of the headers of my Audigy and quite a spark came out - card still works, thank god.
- fought a living hell because of PCI IRQs
- copied a few games - still got a long way to go.

I cleaned the volume pot in the other set of computer speakers I mentioned. The track looks pretty worn, but I don't know where to get a replacement. The pinout is the exact reverse of the Alps RK12L, Bourns PTV112, or now-obsolete Panasonic EVJC, and the retention pins are also offset to the shaft side instead of the rear.

Also, the filter cap in the wall wart failed. I noticed the hum last week, but I just noticed today that the hum goes away in the brief moment between switching power off and the cap on the amp board discharging. It's held together with two hex head screws, and I don't have anything thin enough to fit in the recess to unscrew them. I would like to fix it, but it probably isn't worth buying thin-wall nut drivers (someone probably has an idea on how to open it without spending money). It's a 9V center negative power supply, and there are lots of those around for musical instruments.

It has been way too long since I've fixed something. Either I make it worse or someone I live with demands that I replace it instead (and the replacement is always so poorly designed that it's basically unusable).

Years back, I had a radio I kinda liked, wasn't a "good" one, just cheap and handy and didn't eat batteries too fast, well the pot went bad on that because it was an asshole one with the switch on it, so you had to use it every time, so it was crackly as hell, anywayyyyy, got inside it, was badly worn, colored it in with a soft pencil and it was improved, not perfect but a lot better. IDK if you wanna do that to actual good stuff though.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

The caps still look good, some high quality components were used, like the FSP power supply. And proof that 440BX might be the best chipset of all time. 😉

On-topic; I've been troubleshooting this Cirrus Logic GD5424 with defective DRAM. One mistake I made, is that I assumed U7-U10 defines one memory bank. Doh! Instead the odd numbered DRAM sockets were.

With a 486 SX 25 MHz I get 10.36 fps in the Doom high-detail benchmark from Phil's Dosbench yeah...Now let's try a DX2-66 and fill that VL bus.

Update, after all there were some bad contact(s) in te socket(s). Some Deoxit did the trick and now there is 1MB of memory.

I got a new sticker. 😁 I looked up the board at retro web, but missed that detail. With that label it makes sense.

The 440bx is really the best retro chipset 😀, even if the operating system is incorrectly installed.

During the last few days, I only worked on an MB S.7, a PCCHIPS M550 Intel TX chipset, I solved the initial problem of the BIOS, through a recovery floppy, then I started doing various bench with the i166MMX CPU, which was at reduced frequency (133 MHz), then at normal frequency (166), then due to the multi blocked, I changed it with an i233MMX, and at the moment I am finalizing the benches at 233 MHz, later I will do more at 200, reducing the multi to 3X.
