I acquired a 486 PC and need to enhance the hard drive.
I bought this AT&T/NCR Globalyst 515 486SX loaded with disks, software, and a retro keyboard/mouse/monitor setup for $50. My goal is to convert it into a vintage gaming machine. I already own an 80 GB IDE hard drive, and the current PC runs smoothly. When I started Windows 3.1 on the drive, everything worked perfectly. On my real system, I attempted to back up the old IDE drive to a USB2.0 enclosure, but Windows 11 refused to start it and reported an error. After testing the 80 GB drive, it appears normal. However, when I tried to boot the drive on the 486 PC, it triggered an error and led me through BIOS settings without clear guidance. The BIOS seems unable to recognize the drive or identify its specifications, possibly because the technology back then didn’t support such recognition. (I was around six when this model came out...) I’m considering adding a network card since I’ve seen a YouTube tutorial matching the setup. I’m unsure about expansion options right now. Any advice would be greatly appreciated! Thanks!
Typically, older systems could handle up to 500GB, so your setup should work. I assume you've configured the HDD for the Master drive—check the correct IDE connector or jumper based on your specific drive.
Confirming the size is 500GB, not 500MB. The system responded that it was 500MB. I attempted various master configurations, but the original hard drive lacked a jumper.
What is the size of the disk in your PC? If it's small enough, you might try using crosstalk or another file transfer tool from that time. [You had to assemble an ISTR drive for a 340MB IDE disk into your Compaq 386 portable by changing the BIOS firmware to accommodate its size.]
50 dollars? That’s a big mistake! You should have received it. Maybe they should’ve paid you to take it out instead of charging that much for e-waste. The bios from 1994 mentions five drives—one floppy and one CD, with letters A through E indicating their positions. There are apparently three drives inside the machine.
It's a 486 PC, with most of them discarded as junk. Someone with a bit of expertise wouldn’t get a good price for it. Motherboards typically cost over $100 anywhere, but for just $50 this looks extremely affordable given it’s a full vintage build.
It seems the keyboard is likely damaged significantly. The vintage IBM PS2 is in good shape overall.
It takes me back to those days! I owned a used 286 system when the 486 arrived, and I was really looking for a 486dx66 setup.
You need specialized drive software or XTIDE (either as a standalone card or in a slot on another card) to achieve any meaningful modern drive support on that device. The original BIOS likely won’t handle drives larger than 512 MB. OnTrack can push the limit up to the 137 GB cap set by 28-bit LBA, but you must trick the BIOS and input the correct drive size for a 500 MB device. I suggest using XTIDE since OnTrack consumes some of your regular memory. Drive overlays also prevent modern Windows from recognizing them. SD cards in generic SD to IDE adapters are recommended—they work reliably and are affordable. CompactFlash cards remain outdated, though their compatibility with fixed disk mode is uncertain.
