Received compaq deskpro 386s partial computer. This has the goodies reason I bought it whole. One wrong floppy drive for deskpro M so transferred drive into M which becomes dual 3.5" floppy drive. 😀
Another reason wanting that partial computer was: 2x 4MB 80ns daughter boards which will go with Deskpro 386/25e motherboard which will go in place of the 386sx-16 motherboard.

Will ask in other topic about the configuration compaq did to kit out the Deskpro 386s with 3.5" floppy drive.

Very happy.

Cheers,

Great Northern aka Canada.

While not technicaly computer related, I bought one of those 8bitdo wireless MegaDrive controllers and have seriously been digging it.Minimal input lag, great pad, has optional side buttons. Cord free. Totally has rejuvenated my interest in MD gaming.

Makes me really wish there was something like it for the PC gameport. Nothing better then sitting back, cable free with a comfortable pad. (Unlike you, Gravis Gamepad!)

It's the little things 😀

I've mostly been messing around with that Docking Station for the last week. Will probably put more details into my build thread, but basically I got both NEC Versa (40EC and M/75) running off of it with SoundBlaster and Ethernet.....still got a lot of work to do. Put in a SoundBlaster Pro 2.0 and a SMC 8416 EtherCard EZ. Trouble free in DOS but Windows is making me want to drop back to FreeDOS on those again....after all, they did make a P/75 version of the same exact laptop (Pentium 75, it was the last version ot use the cases the 486s used)....and the dock connector matches the 4000 series so that may be an option as well (I have a couple I have my eyes on ATM). I also upgraded to Links 2.21 and downloaded a 375MB file using the M/75 - took it about an hour it looks like over wired ethernet. Kind of insane a 486 can do that when you think about it....then there was WinRar unzipping that thing (!!!)..... this is like an old IDI Diesel F-250 pickup of laptop computers......you just hammer on it and hammer on it and it still gets you through - it might not be fast, it might not be "sensible"....but it will get you there.

May have found a few suitable touch panels to try on the M/75 on E-bay, one is only $33, but I have two that are over $100 that I'm handling like I did the M/75 and the docking station - just putting a watch on it on e-bay, and then waiting for the price to drop (or for it to dissappear). Also going to bump up the RAM (40MB), and get it a proper Floppy Drive....speaking of, having a real struggle with the Dock CD-ROM in Windows 98 SE and Windows For Workgroups.....works great under DOS but hangs/locks up in Windows for some reason. It's an early NEC CR-560 IDE drive.....go figure. I'm guessing a conflict with the IDE controller on the Laptop possibly.

Also made the wife laugh mocking the Guardian while playing Ultima VII on the M75. "Avatar....know that this here monkey man in the sky will tell you to go fight an evil corrupt politician disguised as Batlin in the local church whose carrying out ritualistic killings befitting of a Ghost Concert"....or somesuch....it was in the moment....

Some interesting ISA and PCI cards, Amstrad PC1640 with a dead motherboard and a working monitor.
A Quickshot 8-bit ISA Deluxe Joystick Adapter, a full-length Everex systems memory card, 8-bit ISA.
A CL-GD5422 ISA, a Hercules Dynamite 128 Tseng ET6000 PCI-card.
Also, an AT tower with an AMD k6-300 and a 5.25" floppy drive that needs some serious cleaning.
An IDE ZIP 100 drive, with the click of death.
Tested the power supplies, all ATX with -5v line, and one of them popped with a bang and blew a fuse, leaving me in the dark! 😀

Nice ! Like the Creative CDrom in the tower.

Started building the Monitor stand for the Versa Dock. I also revived the secondary battery in the M/75 using my truck's battery charger, and started copying over the CD-ROMs for Shivers and Lighthouse to the M/75. Considering bringing out the NEC Ready 9522 to mess with after awhile too. More details in my build thread to come.

I hired a couple of guys to help me clean out my garage. And we setup a couple of racks to organize all my computers.
It still needs work but we cleaned out allot of stuff. Now I can take all my stuff out of the house and put it in the garage.

I finally got my hands on a CRT, a 14" Magnavox, and I excitedly hooked it up to my 486 that hasn't been turned on in about a month.

No floppy (controller failure) or hard drive detected.

I took a look at my VLB IDE controller card and saw 2 busted caps.
I've only soldered a couple of times before, and never capacitors. Could anyone tell me what kind I need to get based on this picture? And is that a normal way for them to break?
The one on the left has a broken leg at the pad, and the one on the right broke differently. There was never a "pop" of smoke, or any residue that I can see. If I didn't know better (and I don't) I would say they were cut with snips.
Maybe it was like this all along, and there is another reason for my floppy/hd troubles?

EDIT: I believe I am confusing resistors and capacitors in my post above.

R5 is a resistor (I can't remember how to read the resistance, it's been many years since I knew the colour codes)
The other component is a capacitor, but I am unsure what type - I need to know that myself 🙁 I can't read the value in your photo (I have to use a 30x magnifier to read them these days). It will be the same as the one marked C10 on the board.

See my graphics card database at www.gpuzoo.com
Constantly being worked on. Feel free to message me with any corrections or details of cards you would like me to research and add.

C10 appears (using my phone's magnifier) to read 104 ZES as do several other capacitors. There are also several that read 103 ZES. Maybe ZES is a brand name?

To the best of your knowledge, would it appear as though this was a resistor and capacitor "blow" to cause that?

The resistor is a 1K ohm 5%, looks like 1/8watt. The cap is a multi-layer ceramic or tantalum. I do not see a red band or marker to indicate polarity so likely not a Tant. If a 104 ZES is a 0.1uF, 103 is a 0.01uF so those are multi-layer ceramic and almost never blow. Are you sure something did not bump the parts ?
When a cap blows it usually does from the middle and leaves blacked ends, I see no black.

Spent the day testing some boxed up spare IDE HD's. One of the old drives failed to spin up after being boxed for about 6 months: Quantum 105AT. It never showed any bad sectors or issues last test Dec 2019 but had been around the block a few times in the last 25+ years 😀 The rest of the small old HD ran/tested just fine. Thinking of buying another similar sized IDE for the old 386 era boards....

I imagine the lubricant inside the drive decided to seize up after nearly 30 years or so . I wonder if it would be feasible to re-lube the spindle without contaminating the drive media or heads .

Yes think so, it will not spin up at all but also do not hear the heads trying move, no clicks or clacks (possible stiction). Thanks for the suggestion ! Might try to open it up as it has a few pre 2000 files on it would like to save. Did that with an old 80Mb and got everything off and it actually lasted a few more years of occasional boot-ups.

Agreed, there's no signs of capacitor "popping". There is, however a long scratch on the PCB near the top solder pad of the two components, extending almost all the way over to the chip ..

Please use the "quote" option if asking questions to what I write - it will really up the chances of me noticing 😀

Pardon the definitely not-retro visual on screen (most of my retro things are packed, and was testing with the laptop I had available), but I just received an HP P910 19" monitor from a family member. Needs a clean up, but seems to work fairly well.

Photo below is the screen running at 1600x1200 / 85hz. It's maybe a little bit soft, but certainly not bad, I think:

For the sharpest display, you probably want to run at whatever the monitor's "preferred" mode in the EDID is; modern windows versions should default to that mode, or sometimes mark it as the "native" resolution as if you had connected an LCD.

That said, when I'm using a modern operating system, I run my 17" Sony E200 using a custom 1440×1080@75Hz mode which is fairly soft - but the combination of super-resolution (that mode's about 0.21mm pixel pitch, but my screen is 0.24mm dot pitch), larger fonts (using 125% display scaling) and anti-aliasing give really nice-looking text.

Good eye, thanks for catching that detail. Something must have happened, although in an enclosed untouched system, I'm not sure what it could have been.
Thanks for all the details on the resistor and cap too, it's much appreciated.

A 60GB DiamondMax was pronounced dead today at 2157. Cause of death: stuck heads.
However everything else from this 1,25€-pile works. Athlon Thunderbird, 512 megs, GF2 MX, SB Vibra 128. Nice period-correct combo paired with a Nokia TFT but I do not like the power draw and PSU requirements at all !

This motherboard or the Nokia monitor taking too much power?

Athlon XP CPUs are power hog, and you have to live with this.
