Fully recapped and adjusted my (35 years old according to the date stamp on the chassis) Technics SP10 mk2 turntable.

That's what it looks like inside. Very complex circuit (this model was designed in 1975), in 1983 they packed all control electronics except the 3-phase drive amplifier into a single IC and the result was called Technics SP10 MK2A. Of course, if that single IC fails, you're screwed because they're no longer available from Panasonic. This model with its fully discrete circuit is infinitely repairable.

The control PCB was recapped as well but I forgot to photograph it.

Old parts. I tested the old capacitors on my LCR meter. The dark blue capacitors tested perfectly. The light purple ones, however, were way out of spec.

PLL timing adjustment. Yes, I did it on the floor in our spare bedroom 😀

Good Work !
Wow that is a lot of circuitry.
I re-worked my old Kenwood KR-8010 from 1978 in about 1998 and it still runs great. It is mostly discrete with IC's only for the Tuner section, the power amps are fully discrete... iirc

Those old Kennys are very nice receivers...

I know we don't really have an eBay thread anymore, but I just wanted to say: Is this the new way to rip people off on eBay?

Some PoS is listing items out of Russia for $1.00 seemingly with the price rolled into the shipping.

I'm assuming the purpose of this is to make it impossible to get your money back via returns?

I HATE everybody who supports the "Friends and Family" only trend that is going through the retro community right now, its just an excuse to rip some one off by misrepresenting your item, and to have no liability if you sell garbage.

No, the purpose is to pay less in fees.

If the item is not as described or doesn't arrive, the seller has to refund the full amount including shipping.

BTW am thinking of getting rid of some old AT stuff like a few 16bit RLL controllers after doing some testing on them or at least make sure I have the docs. I have no use for 6 of them so is there any interest in WD based RLL controllers ? They all worked last time I tested all back 2001-2003 and have been stored properly. Just wondering if there is a market or maybe just donate them to members here. Just curious.
And while looking thru my boxes of junk found this: Whoopy !

Shipping cost has been rolled into the fee for quite a while now. Maybe last 10 years.

I've been messing around with my Athlon XP 2400+ / KT133A build, which I use for both 98SE and XP. Right now trying out different GPU and sound card combos.

I use Ghost 2003 to image the disk after installs, like this one for Catalyst 10.2 and a Radeon AIW X800 XT. Takes about 30 mins to burn the image, a little less to restore.

Took my Powerbook G3 "Pismo" out of storage, since I needed it to convert a Mac disk image. Guess what? It still works without any flaws. I think it was in storage since 4 or 5 years. During this time, half of my other old Powerbooks died or needed at least some repair.

Today I configured a dosbox testbed to compile the original Wolf3D DOS source code to see if I can add "always-run" and "mouselook" (plus WASD control) to it. I already did that with the SDL port, but SDL does not work on DOS.

Did some more work, on my AT/XT to Amiga keyboard convertion. And before anyone asks, then yes, the AT keyboard was dead in advance.

What I did today, was to finish up the mounting on the base of the keyboard shell. This way, the heavy Amiga500 keyboard will not move and slide around inside it's new house.

Next, I need to finish up the top shell. Then I need to create a new data cable.

Unpacked the 2nd to last package from Europe I will likely receive. In it, a beautiful Kompakt Serie III case, with (as always with these cases) anything but a 386 SX inside. Instead, a DX-40 386. The 7 segment was set to 40 as well, so I am not sure if VOBIS quality control just got lazy or wtf.

Again, the original hard disk came in one of those caddy cases. This is like the 3rd or 4th one I receive like this. Replaced with a CDROM.

I also added 4Mb of RAM for a total of 8, erased most of the German software that was on there, put in a soundcard, removed the mobo and took out the battery (almost no corrosion!!) and replaced it with an external cell. The hard disk was moved to the mounting point beside the power supply, I cleaned up the insides, loaded Windows 3.11 and put on the proper drivers for everything.

Wow, nice looking 486. Good job ! Ahh red wine, is it a cabernet' or pinot ?

Hungarian Bulls Blood 😉

I gotta do something about that Turbo LED. I recall over a decade ago I redid my first wife's HVAC controls on her Tiburon. The answer was: Sand the LED down.

Fast forward to now - I'll use a grinder.

The shiners can be converted to glow-er by replacing the empty space or directly to the LED (partially cut off to make room for), with diffuser by using any white translucent material. Can be a off white translucent hot glue, translucent white epoxy etc.

Diffuser is what scatters the direct beam into light-glow that you can see. Sanding helps very little.

Or replace the water-clear LED with 5mm diffused LED of same color.

Cheers,

I have an LED holder and I found an amber and yellow LED - will try these out later, they will look more era-correct. Thanks!

So, everyone on the Computer Reset facebook page? 😜

Curiously, the video card costs the same to ship to Poland as it does to the USA.

Avoid.

I decided to dismantle this Toshiba Libretto 50CT / 70CT battery that I bought that didn't seem to work at all.

2 of the cells were down around 3 volts, so they should be usable when charged up. Sadly one of the cells was down at 1.5 out of its 3.7 volts, so it's a dud.
It looks like it's now impossible to find lithium ion cells in the 17mm wide and 67mm tall (17670) format any more, so I'm thinking of trying a 14650 in its place; lower capacity but it should give a more usable battery 😀

Who at Toshiba thought that a computer with no internal CD ROM or floppy drive, and no USB boot support was a good idea? To add insult to injury their SD Card formatting tool for making bootable SD cards doesn't work with my SD card adapter.

The only way I can realistically get an OS onto this mofo is to start the install on one PC, then swap the IDE drive into another. Fuck this dumb.

You could try setting up a remote install server in a VM and use that. Yeah I know its a major pain to do it that way but if needs must. Assuming that Toshiba has a built in NIC that is PXE compliant of course.

Which Tosh ? My sis-in-law has an older Asus slim lap that would not allow a USB cdrom to be bootable. Just curious....

Fired up a few non vintage PC's that I got from thrift stores during the week. One a Dell Vostro 200, the other a Dell Studio XPS 9100. Paid $30 for both including an original MS Sidewinder game Pad. All work just fine ! Never owned a i7 socket 1366 before so the 9100 was a bit interesting...
There just is no real vintage stuff in my area anymore 🙁

I'm sure you guys know better, but just in case - some laptops don't allow USB boot when the current OS is hibernated. No helpful message is presented.
