The DS1287 is 24pins. It appears that the DS1260 is not a RTC/CMOS it is just a battery and a controller to connect/disconnect the battery from the circuit.

Is there silkscreening on the board near the power supply that says what voltage is supposed to go to what pin?

I believe the TC60 means they are 6ns(166.66mhz)

The CPU is a DX2 66 Enhanced Am486 w/ 16KB of WB cache, which was probably the only DX2 66 that you could still get when this card was manufactured at the beginning of 2000. The thing won't post if I have my Aztech Galaxy Nova 16 (PB OEM) sound card plugged in. The memory module with the card is …

I tried it with just an AT power supply connected to it and the keyboard started responding. So I put it back in the backplane and took out all the cards except the cirrus VGA card again like I did the other day still no post, so I tried a trident card I had laying around same result, but then I …

I purchased this 486 SBC off eBay, and when I plugged it into my backplane it would not post, there is a power light that blinks but that is all it does, I know it is getting power becuase of the LED and that I used my multimeter to probe the power connector on the card and it had the appropriate …

Anyways, remember the Memorex floppies that I've bought two weeks ago? well last night I've found that only 7 out of 10 floppies were in working condition, I tried to write a disk image onto one of them using my Toshiba Satellite 315CDS laptop, I had to format the floppy inside Windows because …

I ended up buying a vacuum desolder station because I couldn't wick all the solder out the the thru-holes to get the ds12887 out. I got the chip out, and got the new socket soldered. The Dallas chips I ordered off ebay were surprisingly new, they had a 31st week of 2016 date code. I also replaced …
Do you reformat preformatted floppies?

Today I got my 6 boxes of 5 1/4 HD disks I ordered off of eBay, I had one box of Dysan 100 disks in a neat plastic case and 5 boxes of Fujifilm disks in cardboard boxes. All of the boxes were brand new and sealed , the Fuji disks seem to be from around 1990 because they have something about the 1990 …

Don't buy a 9500gt or faster PCI card, I bought the 9500gt PCI and found that it is absolutely bottlenecked by the PCI bus, I did a little review last month, https://www.vogons.org/viewtopic.php?f=46&t=54623 , and founf that the PCI bottleneck often causes dropped frames and screen tearing when …

Too bad you didn't get the battery with it, you could have repacked it with new cells. I don't know if that is possible, I once tried to dismantle the battery from my Libretto 70CT and it was essentially potted with epoxy and you couldn't dismantle the battery without destroying it, I don't know if …

Price and demand has no correlation. Yeah they do, supply and demand both affect price, an increase in demand typically increases prices, a decrease in supply will increase prices, on the corollary a decrease in demand tends to decrease prices and an increase in supply will do the same thing. Gold …

I got the solder wick from amazon today and went to desolder the existing clock chip, long story short my Chinese eBay station spent a little time airborn, and I bought a Hakko station bundled with several tips off of amazon. See my tutorial video on how to properly use a Chinese no name solder …

I've found that with NE2000 compatibles when running WFW 3.11 that the built in NE2000 driver works even better than manufacturers drivers at least when I was using 16-bit PCMCIA card in an old Winbook that I had, that I later accidentally fried by changing out the CPU while it was on, which …

I think I have thought of a cheaper way to do the whole thing, get a some DIP-24 DS12885 chips from allie express, get a really tiny SMT 6pf 32.768khz oscillator , then get some really sticky solder paste . then you could either try to place the oscillator between pins 2 and 3 from the side of the …
