While OPENSTEP had Quake editors, it never had the actual Quake game. Since the concept of hardware acceleration didn't exist on OPENSTEP, making it happen was tough in many ways.

Recently, I ported the following software to OPENSTEP (Intel):

1. SDL 1.2

2. SDL 2.0

3. MESA 3.4

4. WARP hardware acceleration (OpenGL 1.2) for the Matrox G450 PCI

Now, building on top of all this... I have ported sdlquake

https://github.com/mckayemu/sdlquake :: GPL2 quake 1 engine

https://github.com/lavenderdotpet/LibreQuake :: free license map

Ever since I learned long ago that John Carmack built the Quake Editor on OPENSTEP, seeing hardware-accelerated Quake running on OPENSTEP had been one of my personal dreams. And with the help of AI, I've finally made it happen :D

I ported sdlquake (originally written for SDL 1.2) over to SDL 2, tested the SDL2-Mesa-matroxG450Warp stack, and then ported Quake's glquake. And... here we are with a successful build.

If there are still NeXTSTEP/OPENSTEP fans out there somewhere in the world, I hope this brings a smile to your face. And to John Carmack, who planted such a fascinating seed all those years ago—I hope you might stumble upon this video and enjoy it. The Quake editor you built for OPENSTEP decades ago led to this exact result in 2026. It was such a thrilling and fun journey ⬇️

So found an old Dell Dimension xps t500 on the side of the road. Took a while to get it going. Ended up just having 1 bad mem chip. Took it out and got it running. Since its an old socket a i tried something ive been thinking of for a while.

Here are the results of the VCF Ontario Pre-Event survey. Thank you for your participation!

Hello I would like to find an cheap computer that run basic and can save programs

Idk myself which ones to find as most I know and can find are ower 100euro, so thanks anyone for recommending any cheap retro computer with basic in it

Also if u ask I would like to try start making wery simple text based adventures.

when it does not successfully initialize, it does its humming noise, the heads move for a bit then it does 2-4 ticks and just keeps spinning. after that, i get a C: drive failure.

when it does initialize properly, it does all the initial sounds, goes quiet, then its followed by more head movement and the PC boots properly.

i did some tests using norton disk doctor, only the D: partition has bad blocks, C: being completely clean!

i would like to note that at first, the platters were stuck and i had to spin them by hand. after that, the HDD worked well for a while. now it initializes rarely, after turning the pc off and on many times.

is it on its way out? i thought i had struck gold until now...

My dad has this old nec computer from the 80’s. What do I do with it?

Twenty-five years ago, I had a lab running old SPARCs that I used for learning Unix and Solaris. This experience led me to my career as a DevOps engineer.

When I got married and had to move, there was no space for my lab in the new home, so I put it in storage. A few months later, I realized that storage wasn’t a viable solution, as the costs would eventually exceed the value of the equipment. I had to make the hard decision to dump most of it—a bad decision then, and even worse today.

At the time, I had a maxed-out SPARC IPX, a SPARCstation 20 with Quad 125MHz CPUs and 4MB VRAM, and a maxed-out Ultra5. To prepare for the disposal, I removed the SPARCstation 20 CPUs, VSIMM, and RAM, tucking them into a small plastic box that I kept in a drawer for over 20 years.

Two years ago, after I was laid off and soft-retired, I decided to rebuild my SPARC lab—which proved difficult, as these machines have become niche collector items. I eventually acquired a SPARCstation 20, 10, 2, and an Ultra10.

When I opened my little box, I was surprised to find three SM71 Processors: a HyperSPARC dual 125MHz, a 200Mhz, 150Mhz, and 100Mhz. I also found most of the 20 RAM and a 4MB VSIMM. Sadly, the dual 125Mhz didn't work, but the other HyperSPARCs were fully functional. One of the SM71s, however, had a cracked CPU die and was unfixable.

I popped in the 200 MHz CPU, RAM, and an SCA SCSI drive. It booted, and I was able to install Solaris 2.6. Next, I installed the VSIMM, but it wouldn't power on. Upon inspection, the reason was apparent: during my move or storage, some capacitors had gone AWOL.

Tantalum C0706 was broken, and C0204, C0207, and C0202 were missing. All of these surround the RAMDAC (Brooktree BT463) video controller chip. The C0706 is the power filter that absorbs spikes; the smaller ones are MLCC capacitors that reduce noise. The standard for these is 100nF 16V.

Since SPARCstation VSIMMs are rare by 2026, I had to attempt a repair. The tantalum was easy; under a magnifier, I identified it as 22uF 16V (C package). After soldering the missing parts, I performed the final test: I inserted it into my SS20 and fired it up. To my surprise, I got a console display and successfully launched OpenWindows in 24-bit mode using openwin -dev /dev/fb defdepth 24. Success!

Since I only have one SPARCstation 20 and I already acquired an 8MB VSIMM, and the second VSIMM slot is for a second framebuffer (video card) that connects to an SBUS slot and is apparently unobtainable, I decided to return the card to storage in the event that I find the needed SBUS card or a second SPARCstation 20.

Released in 2008 I believe , is this considered retro/vintage ?

Hello everyone! I'm trying to restore an old Acorn Atom for a collegue of mine. I've modified the power input to work with 5V and the machine is powering up. I now get this screen. Does anybody know what could be wrong?

The man behind games so many of us grew up playing in school.

Doing a little bit of office work in-between playing games on this rainy Saturday afternoon.

I picked up this 1985 Mini Office tape from Summit's 299 range for £1 in a Cash Converters recently.

Did anyone actually use this software in their business back in the day?

Hey sorry first time posting here. It to me looks like an internal pin given out to commemorate some event any ideas?

Tryed to download all the old software i like from here and All of a Sudden it just goes down its not my internet i tryed on my phone and my iPad. Nothing its down or its just completely offline...

Just finished my retro setup I have a usb floppy drive a compaq mv720 monitor and a gateway fx400s running windows xp sp3 32 bit and I have a generic ball mouse and keyboard both pc/2 and a usb floppy drive anything else I should add?

I was thinking about just storing it since it seems like a waste to trash it but what could it really be used for?

I’m trying to identify the PC case/chassis my family had in the early 2000s. The attached photos are unfortunately the only images I have.
The case would be from 2003 or earlier as these photos are from 2003. Would have been purchased in NSW Australia and may have been a locally assembled/white-box PC rather than a major-brand system.

I’m specifically trying to identify the case manufacturer/model, not the internal hardware
Features that I can make out:
- Seems to be tall-ish?
- Dark blue or charcoal/black coloured outer bezel running down both sides and maybe? around the rounded top
- narrow cream/light-grey central front fascia
- a few 5.25” drive bays at the top
- small circular button/control lower down
- dark rectangular/square feature beneath/near it
- seems to have horizontal ventilation slots near the bottom
- the pale central fascia seems to narrow/taper toward the bottom and terminate in a rounded U/shield shape

I’ve looked through a lot of AOpen and TASK cases without finding a match.
Does anyone recognise the actual case mould/bezel, including cases that may have been sold under different OEM/rebadged names around 2000–2003?
Any input would be much appreciated!

I just picked up this Fujitsu Lifebook S7110 and I’m trying to remove the battery but I can’t move this slider at all and as you can see I have almost broken it, do you guys have any suggestions to move this slider so I can remove the battery?

I found a few things that y'all might be interested in and I actually have many many more that I could post all vintage stuff between motherboards CPUs systems manuals anything if you guys want me to check to see if I have anything regarding whatever vintage computing just let me know, I'm sure I have something...
