Tested out a mod I'm going to perform on my Acorn Electron - adding a 3.5mm jack output for audio out instead of using the internal speaker. This will allow me to control the output volume via a TV or AV receiver etc.

I didn't have any spare female jack connectors in my collection of wires so I've had to order one. In the meantime I just connected a Phono cable up to a spare jumper cable I fitted inside in place of the speaker and then sent the output to my TV. Seems to work fine and I can finish off the mod properly when I have the cable. Should also be able to slot the wire out through the side by the RF output, which I'm not presently using.

The good thing about this mod is, it's totally reversible. I'm leaving the internal speaker inside, just not connected.

I'll have to try and mod the RGB Scart cable too and add a 3.5mm jack audio cable.

Repaired cyanoacrylate residue and a broken resistor on a Cirrus Logic CL-GD5401 ISA card. Not a piece of gear anyone will be rejoiced to hear is functional again, but 8-bit compatible VGA cards will become fairly handy and rare in the future I think..

If it means someone can avoid a Realtek vid card, you're fighting the good fight.

Noticed that my Creative SBS35 speakers have a lead fracture yesterday. Instead of fixing the permanently attached flimsy cables, I decided to add proper connectors. One speaker done, one more to go.

Neither retro, nor modern...

I have never seen so much DDR1 memory in use in one machine, let alone done it myself.
First I thought the sticks were incompatible, as there is a 23 second (!) period of nothingness after hitting the power button. Screen stays black, you think the board is not posting or memory is incompatible or GPU is broken or smth else... Then all of a sudden... BEEP

Essentially a quad core (2x dual core) paired with 32GB memory. Still going strong today.

Today I fitted new microswitches into a Cruiser Joystick, to replace old/worn ones.

I've been testing out various Commodore 64 games with it for most of the day and it's now working great. The ability to alter the stiffness of the stick is quite handy for different games, ie. the loosest setting would be ideal for games such as Winter Games and the like, whereas the middle setting probably best suits most platformers.

Also today I completed a quick & simple reversible mod on my Acorn Electron, adding a 3.5mm jack socket for audio output. The speaker remains inside, just disconnected in place of this socket.

The result looks ok when everything is connected up -

Yesterday was cleaning up around the house, going through some boxes since our last move (almost a year ago, yeah we're those people), and finally found the box with my Monster 3D Voodoo 1 and Voodoo 5 5500 GPUs!! I've been sweating bullets lately because I've been wanting to continue building my retro rigs and I had no idea where those were. I was scared to death I lost them somehow during the move, and the 5500 ain't cheap or easy to replace. So now I'm going to test a bunch of Voodoo cards, make sure they all work.

Started restoring a 486 VLB board by QDI that has some battery-leak damage. After cleaning and investigating, it seems I only have to replace the socket for the keyboard controller.

Nice ! Got any pictures ? Am amazed at how you and some of the others here have resurrected some badly damaged boards.

The second speaker was quite a bit harder to do, with two connectors to add and the large pcb inside. But I can't complain about the result. 😁

At least it's 9VDC and not 9VAC, what Creative used on their much later speakers, which are atrocities...

Too bad, the speakers are still not working correctly. One channel is much quieter and sometimes get louder when moving or rotating the speaker. But I can rule out broken cables now, also volume knob etc. are tested and good. Resoldered the amplifier chip too with no change. I guess I need to reflow all solder joints and re-cap the pcb. Or maybe the amplifier chip is bad, since there's also a slight channel leak.

Recent retro activities:

1. Fired up the Gigabyte GA-5AA Super Socket 7 mainboard I found in the "Voodoo 5 scrap lot" the other day. Pleased to find out that it does not only POST, but already has the latest BIOS installed for K6-2+ support. Guess I have to build another SS7 box then. *shrug*

2. Tested the Voodoo 3 3000 that I got for cheap, seems to be dead. Meh.

3. Played around with the Pentium MMX 200 laptop that I recently bought.
The good:
- Relatively good overall condition
- Everything that came with it seems to work fine (more or less)
The bad:
- What I thoght was a missing battery turned out to be a missing HDD tray and HDD. Completely proprietary, of course. So unless I get another one of these machines, I probably won't be able to install a HDD.
- No optical drive either, but I knew that before

So I am basically left with a 3.5" floppy drive and a CF to PCMCIA adapter I had in the drawer. But the laptop won't support booting from CF card, so I had to figure out other ways.
Tried to boot Plop boot manager with pcmica support --> no support for PCMCIA to CF adapters.
Tried to boot Plop boot manager + PCMCIA USB 2.0 card + USB thumb drive --> not recognized by Plop
I ended up using the APSoft ATA enabler for DOS and a DOS boot floppy and somehow managed to get through the Win95 install routine. But starting Win95 from a DOS environment afterwards yields all sorts of errors and this is where I gave up for now.
Since I really like the machine, I might end up buying a second one just for the HDD tray.

4. Took out my dual Socket A board (Asus A7M266-D) just to confirm that it is dead. Fans start spinning as soon as I plug in the power supply, but that's it. Apart from two slightly bulged caps the board looks good, maybe I'll replace them some day and see if that changes anything...

I wonder if this is the right part to connect the HDD on your Highscreen Lebook advance laptop? https://razborka-pc.prom.ua/p714484229-plata- … a-shlejfom.html

I finally found a beige DVD rewriter for my K6-3 Time Machine. I had a couple of them go bad on me and was reduced to using a black model.

The case has yellowed to the point that the beige still stands out, but it's still better. Plus, this new NEC drive is absolutely silent. I need this period incorrect component to burn disk images onto DVD-Rs.

How 'retro' are we talking about here? 😁

Carpentry, with no power tools. Rebuilding an already very reinforced fence that got snapped right in half during the last hurricane. Hammer, chisel and pencil to make mortise and tenon joints in 4x4"s.

What no hand saw ? 🤣. There is a certain joy that comes from working with wood products that is hard to compare to anything else.

added: sorry just had to necro-reply

Tested a smll box of 30 pin simms today, about 150Mb worth. Found a set of four 4Mb 80nS that were in the box that did not know about. Also found four AST 64pin 4MB simms that went with an old Bravo (?) board that died years ago. Anyone need AST 64pin simms can PM me and you can have them free (but you have to prove you have a board for them, 🤣). Used a good old Opti 386/486 board to test them with.

Wow, that could actually fit. The "Highscreen LeBook Advance" was in fact a relabelled Chicony MP975.
BTW, a copy of the parts list is still available on archive.org, but it didn't help me so far: https://web.archive.org/web/19980213163820fw_ … .com/mp/975.htm

The connector seems to match and the part number in that Russian Ukrainian shop has a "975" in it, so chances should be pretty good that this is the right part.
Man, they even have the CD-ROM drive listed that my unit lacks. And the parts seem to be really cheap, too. At least if Google translate didn't fail on me. 50 rubles for the adapter, 40 for the CD-ROM drive, that's about 1.30€ total. Plus shipping, obviously.

-- Edit: Prices seem to be in Ukranian Hryvnia, not Russian Rubles. Still cheap, though.

Now I just have to figure out how on earth I can place an order without knowing a single word in Russian. Gonna pass these guys an email. 😉
Thank you Thermalwrong!

Updated my collection gallery with Graphics Cards. Next up I will post my Sound Card photos up and my collection will be completely online 😀
