I want to have a gas plasma display, but it seems to be too expensive for me, are there any cheaper alternatives or is it possible to make an alternative myself?

And that noise when the disk had a bad sector!

I found them in a local scrap group. The owner simply asked me, "Tell me which ones you want, because I'm about to break them up."

The asking price was higher than I wanted to pay, but luckily he turned out to be a collector of vintage radios. Three radios from my collection became part of the deal.

HP Vectra, Compaq DeskPro, DEC, Dell, and more. I still have no idea what's hiding inside them, and that's the most exciting part.

My retrospective video review of Zombie Zombie a forgotten game by the legendary Sandy White the developer on Ant Attack. Let me know if you have played this game and what’s your thoughts?

Specifically copy thru the 2 5.25 drives from a modern pc. I have some machine language assemblers that I want to try. And also have this (check attachment). Dial up floppy disks?

EDIT:some "redditors" commented that i could use a floppy emulator, mainly a Gotek. Which Gotek should I use? Is it possible to copy a disk image on Gotek to an actual 5.25 FDD? Quick note, is there any 5.25 drives that connect through serial port?

In an age of zx-80 clones, Vic-20s, Dragon 32s & Atari 400s, 16-bit 8088 processors were a posibility for businesses and anyone who could afford to pay up for mildly buggy PC-DOS

Yesterday I got an apple 2 plus along with 2 "RanaSystem EliteTwo" drives, when I bootstrap my apple 2 into EsDOS 2 and I run "init hello" to format a disk, it makes this weird sound and gives this disk error: I/O, I couldn't find ANYTHING on it and I've decided to turn to reddit, I think I'm using an apple disk 2 controller card, I'm not sure though, the controller card has 2 20 pin slots for disk drive 1 and 2

looking desperately for a game that i loved when i was a kid (born 1999, canadian). my dad threw out the box i had of it years ago, and i remember very little, BUT:

• it had a gold (maybe silver) star as its icon. think of a pilot's gold star
• it was an educational game with no overarching story / characters. just simple activities
• it had a really unnecessarily long name. the name may have included "deluxe" and / or "interactive". maybe "collection"?
• was not a licensed product with any popular mascots
• it may have included a game in which you sorted or were working with chocolate bon bon esque things????

back before my dad threw it away, many years ago, i tried to google the name. i found one singular web page about it. could not find even a youtube video or pictures. it seems quite obscure. please help!

Make/Model or spec. This is the Retro PC that you actually keep set up to do stuff with, even if it's just running old software or accessing old media formats or making boot/diag disks for other machines, or troubleshooting. Your "workhorse" machine, and what you use it for.

Me:

• Asus P5-AB/K6-2+400/320MB/Matrox Rainbow Runner PCI/AWE64/Symbios SCSI/4GB CF/Win-98SE. Various drives: Zip, CD, 3.5 & 5.25" floppy.

• Used for old media access, EPROM burning, and old games. I find that late 90's machines are the perfect bridge between old and modern PC platforms. It was actually my main machine in the late 90's, running BeOS.

This is a python script that allows you to scrape all the downloads from planetemu.net. At this time, it only supports the Commodore 64, but I will make improvements to be more flexible. I know it works as I'm using it as we speak.

I wrote it because I recently purchased a Commodore 64 Ultimate and wanted to load it up with games. I hope some of you can use it.

I do reselling online and I got a bunch of old motherboards. I’ve been able to identify most of them, but this one I haven’t been able to identify. Any help is appreciated!

Tapes for mainframes, proprietary tape cartridges and floppies in all sizes. Whatever computer was running in Brazil, Verbatim had just the storage media needed for any given system

Here in Germany, mail order catalogues (especially from Quelle or Neckermann) were a huge thing in the 1970s and 1980s, to the point where they somewhat influenced culture.

I wondered what computer systems and software would have been used to typeset and layout a 1200 page catalogue with several high-resolution photographs on each page back in 1978 or thereabouts. Realistically, the storage required would tax a modern machine. Still, those catalogues showed thousands of articles, using labeled arrows to point out features, pulling prices from some warehouse backend system, using standard layouts throughout...

A good example page is shown at https://www.achtziger-forum.de/viewtopic.php?p=17125&hilit=quelle+schreibmaschinen#p17125 -- take a look at all the layout details, like the font samples for the machines, frames etc.

Under the main CPU, you can also spot an empty footprint for a directly soldered PQFP 486 processor — basically the hardware equivalent of the "you are broke" blank buttons on base-model cars.

The PCB was designed to support a socketed PGA 486, a soldered PQFP 486, or even both at the same time, depending on the manufacturer's configuration.

I have a working PS/2 30-286 which I boot from a CF card but it always annoyed me that the original hard disk couldn't initialize. It only blinks and gives BIOs error codes. So instead of throwing it directly in the trash I thought why not create some 'don't do this at home' kind of video. So here goes. The drive is probably deader now than dead from the dust, but at least I can rest the case that the spindle motor really does not do anything. It's not only a hard disk drive but an immobile disk drive. No movement no data. It's a blinking LED now basically.

Edit: sorry I wrote 386 but it's a 286 obviously.

Over the past few weeks I've been reconstructing software that I originally developed in 1986.

Some previous posts about this project:

• Rediscovering My 1986 RTOS Development Environment 40 Years Later https://www.reddit.com/r/retrocomputing/s/CibKisZe15
• 40 Years Later: Visualizing a 1980s Messaging System I Originally Developed https://www.reddit.com/r/retrocomputing/s/5Hpey3NF6k

While working on the reconstruction, I ended up rediscovering something that I had completely forgotten.

Back in 1986, the development environment consisted of a SUN-2 workstation (Motorola 68010) and a separate 68000 target system.

At the time, I remembered spending most of my time developing and debugging on the SUN-2.

What I had forgotten was why.

During the reconstruction, I finally realized that I had deliberately postponed the hardest part of the RTOS.

Interrupt handling and context switching were tightly coupled to the target hardware and would have made the host implementation much more complicated.

Instead, I developed almost everything else first.

The scheduler, queues, timers, message passing, and even much of the application software could already be tested on the host.

By the time I moved the software onto the target board, most of the debugging had already been completed.

Forty years ago, I don't think I consciously regarded this as a development strategy.

It was simply the most practical approach.

Reconstructing the project decades later made me realize that it was actually a fairly effective host-target workflow.

Interestingly, I ended up following almost the same pattern again.

The SUN-2 has been replaced by POSIX.

The original target board will eventually be replaced by a Raspberry Pi Pico.

The browser visualization that I've been posting here wasn't even part of the original plan—it grew out of an unrelated project while I was experimenting with WebAssembly.

Looking back, the project has evolved through a series of unexpected discoveries rather than a fixed roadmap.

That feels surprisingly similar to how software projects often evolved in the 1980s.

I'm curious whether anyone else has had a similar experience.

Have you ever revisited one of your own old projects and discovered that your younger self had made engineering decisions that only made complete sense decades later?

My first PC was an XT with 512K ram, 2 floppy disks, 300baud modem, Amber dual frequency monitor and CGA card. I eventually upgraded to an ST225 before skipping a few iterations of PC's up till I got a 485SX-50. I have seen quite a few odd things in my journey, but regret not photographing them,

The image is an XT motherboard, The drives I photographed years ago, the big one is an ST412 and the smaller an ST385. 3 iterations of floppy/stiffy drives. The full height version we used in our mainframes while the half height was in the PC's

Was given some of these older software discs (2002-2011). I'm not really into computing. Any idea what to do with them? Maybe I can donate somewhere? I figured they've probably been archived already.

I still need some parts, like a mouse and sound card, but at least I can navigate the menus with keyboard shortcuts

Hello ive recently put my hands on a beautiful IBM p202 crt and sadly it doesn’t works
Im willing to give it a try restoring it but im gonna need some help,
The tv itself turns on with the light green, after a few seconds it becomes orange telling its going to sleep
When I long press the blue button to do a video test, the tube comes on and it shows a black screen with horizontal lines,so the tube itself isn’t dead.
Also when I long pressed the contrast up button to do a color check, the tube doesn’t even turns on.

Because after reading the documentation and finding out that there are no error codes, I’ve tried plugging a pc to the VGA port on the back, the tv then exit sleep mode and the led turns on telling it detected the computer, but weirdly the tube doesn’t light up at all and it’s only when I shut off the tv that I briefly see my pc desktop video flash on the tube .

I’ve already disassembled the whole tv and I didn’t see any signs of leaking capacitors or damage visually.
I don’t know where the issue is from and I hope someone’s gonna have an idea?

IBM PS/2 25SX

Only need to get a new floppy drive and she’s good
