Is this worth anything to anyone?

Found this in the trash the other day and I was wondering if it's worth anything to anyone in the used market.

They seem in good condition but I'm no expert, my knowledge on retro hardware is non existent, all i know is that i tried to boot it with multiple ram configurations and it kept giving me ram beeps, and i don't have any spare ram.

I wanted to sell these for very cheap (or even giving them for free if i find a local) because i can't verify if they work, in what condition they are, and besides the cpu i can't identify any part.

Just wanted to know if it's even worth putting these up for sale, since i live in Italy and i don't know if there's any demand for this.

Have your old resistors drifted way out of spec before?

I’ve been repairing an old IBM monitor recently and stumbled into something I honestly didn’t expect at all. I knew capacitors commonly fail with age, but I didn’t realize old resistors could drift this badly too. After chasing brightness and scan line issues forever, I finally started testing more components and found multiple resistors reading completely wrong. One resistor that should’ve been around 10M measured closer to 6M, which already surprised me. Then I kept testing and discovered several more old resistors way outside tolerance. The weird thing is most of them still looked physically fine. No burning, cracking, or obvious damage anywhere.

Now I’m wondering how common this really is with vintage electronics. I always assumed resistors were one of the safer components to trust unless visibly damaged. I even ended up reading repair discussions involving surplus resistor inventories and online electronics suppliers because I’m trying to decide whether bulk replacement assortments are worth keeping around.

For people repairing older computers or monitors regularly, have old resistors caused more issues for you than expected over the years?

Laptop identification?!

In Iron man 1 while they are booting up the suit for the first time, there’s this laptop and I’m very curious what I could be ? Seems like a Toshiba satellite to me but what does y’all think?

Pallet of retro computers - Is it worth saving/buying?

I have the opportunity to buy a pallet of retro computers from a e-recycler. Mixed pallet all computer systems from the 90s. I plan on buying it to fully refurbish the systems and sell them at 80% retail online shipped and on FB 50-40%. The price per pound is $1.08. Total weight is 2076LB for the pallet. Total cost $2242. Are these systems worth saving based off the photos? Wondering your thoughts.

Also they are selling two other pallets of retro computers which are lighter in size. I attached photos of them below including higher res photos of the first pallet.

PALLET 1 (2076 LB COST= $2242) - https://imgur.com/a/qG7GRva

PALLET 2 (1625 LB COST= $1755)- https://imgur.com/a/3rxR2H8

PALLET 3 (1382 LB COST= $1492) - https://imgur.com/a/oz0AUTz

=EDIT=

Thank you for the quick replies! This is my first time having the opportunity to buy something like this hence why I needed an opinion on it. As much as I love retro computing and saving old computers, I also have bills to pay so honestly this needs to make financial (taking account for time it will take and initial cost) sense for me to do even if I'm buying it for the sake of my hobby we share.

I got 50+ floppy discs. What should I use them for?

I received around 50 floppy disks that the company I work for would throw away. There’s nothing classified or important in them, so I can format it normally. My question is: how can I use them in a creative manner? Mainly retro gaming related, but definitively open to other ideas.

Of course, the most obvious thing to do would be to discard it or use it as decoration, since they have much less space when compared to other media. But since you also like retro tech around here, I think you’d agree with me that there’s some charm to using old technology.

I thought about storing some NES and Game Boy games, as well as games from other consoles that don't take too much space. That way, I could play them on an old computer, maybe using Windows XP (or a version prior to it).

(I’ll maybe store some of the books I eventually write, since I’m an amateur writer and text documents are so small – of course, I’ll back it up in other places too).

Any other suggestions/tips?

RetroCapture 0.7.0-alpha: shader-preserving distributed playback, public stream directory, HTTPS, bilingual UI

Hey folks, the latest alpha of RetroCapture just dropped and it has the biggest set of new features in a single release so far. Quick recap for those new to the project:

▎ RetroCapture is a real-time video capture app for Linux and Windows that applies RetroArch GLSL shaders (CRT, NTSC, xBR, handheld, etc.) live to feeds from capture cards. It does HTTP MPEG-TS streaming, local ▎ recording (MP4/MKV/AVI), system-audio capture, and ships a full web portal. Cross-platform: x86_64 Linux + Windows, plus ARM64 (Pi 4/5) and ARMv7 (Pi 2/3/Zero).

https://preview.redd.it/opte33s9ve2h1.png?width=1923&format=png&auto=webp&s=012257ee6baf6c05b7e6466cb3365067da81af33

What's new in 0.7.0-alpha

🔁 Shader-preserving distributed playback. This is the headline feature. Connect another RetroCapture instance to a running one as a Remote source and the receiving machine pulls the host's pre-shader feed plus a sidechannel of the host's current preset + parameters. The image renders with the exact same shader output on both ends. Live preset/parameter sync — change something on the host and the remote view follows in real time.

🌎 Public stream directory. Opt-in, one-click publish to directory.retrocapture.com. Other RetroCaptures see your stream in their in-app browser and connect with one click.

https://preview.redd.it/qn4g8x4yte2h1.png?width=940&format=png&auto=webp&s=3e5af40ea31e88c503bd933f2a0aed7baa1c5d3a

☁️ Cloudflare tunnels (Quick + Named). So the publish works behind CGNAT without portforwarding. Quick mode uses an ephemeral trycloudflare.com URL with no signup; Named mode persists under your own Cloudflare hostname. cloudflared is auto-downloaded with sha256 verification.

https://preview.redd.it/7h7f1m35ue2h1.png?width=1011&format=png&auto=webp&s=1889823111aaa015ce93ceed2b92b52ec9635528

🔒 HTTPS / TLS everywhere. Directory and /raw connections default to https://. OpenSSL-backed with hostname verification + SNI. AppImage builds work out of the box (CA-bundle probing on startup).

⏺️ Recording pipeline parity + unified UI. Recording and streaming now share the same A/V sync engine, so they don't drift away from each other under load. Every Configuration tab adopts the same layout idiom.

⚡ Quick Actions OSD + Shortcuts helper. Pinned overlay with stream/record/browse/disconnect buttons reachable even when the main UI is hidden, plus a top-right keyboard shortcut reference.

https://preview.redd.it/s7igp0jlue2h1.png?width=1922&format=png&auto=webp&s=f3a7cc19b13623253cafac7e9698aa4398031418

🌍 Bilingual UI. English and Brazilian Portuguese, switchable at runtime.

Bug fix highlights

A real testing pass on /raw long sessions surfaced and fixed:

  • Catastrophic A/V clock corruption on mid-join (audio clock drift=-221_887_834us).
  • AAC probe race on reconnect (Audio: aac, 0 channels).
  • Consumer dead-lock when video probe gave up.
  • /raw going silent when the host toggled the shader off.
  • Ghost audio playing after disconnect.
  • Remote source upside-down without a client-side shader.
  • Windows installer not finding the shader folder after install (last-minute fix that made the release).

A Chorus of CPUs - Scientific American Dec. 1991

[A Chorus of CPUs](https://parhamdata.com/Transputer/ChorusOfCPUs.pdf) in the December 1991 edition of Scientific American described supercomputer designers dreaming of a Teraflops machine and the exotic languages that would be needed to program them. I remember reading it at the time.

35 years later an M5 Macbook Pro delivers over 16 Teraflops and we program them in Python (with a little help from PyTorch). So much of today's technology - TCP/IP, WiMP interface, C++, SunOS, even Python - already existed by then it can obfuscate the advances that have occured. I mean, I'm still writing Bourne style in my bash 😂

Unreadable CD key in NOS Company of Heroes

I found a new old stock copy of CH at a thrift store for $1. Got home to install it and found this! Even back in 2006 this would have been annoying. Good thing the internet could provide me a working key in seconds instead of trying a return at Best Buy or an hour-long phone call with THQ / Relic support.

I've built a virtual museum with nearly every operating system you can think of

Today I am releasing the Virtual OS Museum, which is the world's first multi-platform interactive virtual museum of operating systems and standalone applications, implemented as a Linux VM.

Nearly all well-known OSes and platforms (and many obscure ones) are included in some form, spanning the entire history of stored-program computing from the 1948 Manchester Baby to the present day. This is the result of over 20 years of collecting emulators and VM images; over 1700 VM installations are included, across over 250 platforms, representing nearly 600 distinct OSes.

I have put a lot of effort into making this readily accessible; all OSes and emulators are pre-installed, and a cross-emulator graphical launcher with a snapshot feature to revert VM installations to a working state is included. Shortcuts to run the OS museum VM on Windows, macOS, and Linux are included (and it is possible to run it on pretty much anything that runs QEMU or VirtualBox).

Vintage Apple rescue FTW!

I visited my old job today to pick up a printer and the staff (whom I’m on great terms with) asked me if I wanted some old computers that a customer had dropped off for donation/disposal. I said “yes please” as soon as I saw the Apple II and it just got better from there. Full original docs for the Apple II, an eMate 300 with original docs and stylus (alas, no power supply), a PowerBook 3400c… Everything’s in excellent condition, and all of it for $0. Gonna see how much of works this weekend.

I found the beginning of the internet on my TRS80 model 4P

I just thought I’d share my little project I’ve played around with over the past few years. I always wanted to try to access some bulletin board systems on my old TRS-80. After watching a video years ago where someone dialed into a BBS on a TRS80 with a rotary phone and an acoustic modem I was so fascinated. Shortly after I found a nice model 4P on Ebay and played around with it a little before losing interest for several years.

After moving into my new place I decided to have a go at configuring a VOIP landline over my Starlink. I got an Obidata gateway and pulse tone converter and dove down the rabbit hole of trying to get it all working. I was eventually successful and immediately set up my two old rotary dial phones and even bought an old cassette tape answering machine. I was so stoked.

Shortly after I decided to get back into trying to get my old TRS80 online. After many attempts and a fair bit of research I was eventually successful but only while using my internal dial up modem. It was finicky at best but I was beyond stoked. Shortly after I scooped up a few old acoustic coupler modems from Ebay and began further attempts at accessing some BBS’s with Rotary dial phone. I found this to be considerably more finicky and unreliable than the internal modem which was pretty bad to begin with. Also being a 90s kid, this is all a bit before my time so I’m sure I still have much to learn but nevertheless I was able to get it to work on few occasions and was sure get some photos and videos of it all. I thought y’ll might find this to be pretty neat. I know I did!

any idea how i can fix this laptop?

The laptop turns on, but there's no image or any other signs. Nothing on an external monitor either. the components work normally: the disk spins, the DVD drive ejects, generally the components get warm when they are running for a while. The laptop doesn't respond when I turn it on without RAM, I think it should beep normally then, could it be the motherboard's fault? I would be grateful for any advice!!! The laptop model is Medion MD5400

Need help figuring out what I can do/upgrade on an old 486 I was gifted

To make a long story short im now in possession of a 486 PC from about 1992 if my research is correct. Its a Zeos machine that according to the previous owner was used for CAD in the early 90s? I wanna use it to play some DOS and early Windows 95 games but im not exactly sure what im able to upgrade on this system.

Right now it seems to have the following hardware installed

  • A Zeos motherboard (This is also a Zeos system if that helps)
  • An Intel i486 DX 50MHz
  • An unknown amount of ram
  • No L2 Cache
  • A Diamond Speedstar 24 (Which from what ive been able to gather is a really good ISA 2D video card? So ill probably leave that as is seeing as I dont have PCI or VLB)

I wanna upgrade it to be closer to something around 1994-1995 in hopes that it might be able to play Duke Nukem 3D and possibly Quake? But im not sure what if anything are drop in replacements.

I was thinking about putting in

  • A Cyrix 5x86 or Pentium Overdrive (Seems like a drop in replacement for this 486???)
  • A Soundblaster Awe-32 or Soundblaster pro 2.0
  • Some amount of L2 Cache
  • and a Roland Mpu-401 compatible card to use with an MT-32 or something

Not sure how much of this is possible but thats why I figured id ask here since you guys probably have more knowledge about this than I do
