Old 486 SX Computer With DOS System Yamaha OPL3 Sound Card. Incredible Revival

🖳OLD Computer With 486 SX Intel Processor and Dismaq Cabinet! Powered by Yamaha OPL3 Sound Card and ESIJMJG Restoration 

    We present the first "Level 2" restored AT 486 desktop PC—featuring a horizontal case and an 👾incredible DOS game pack—restored by ESIJMJG in Brazil. We are showcasing this fantastic AT 486 PC housed in a Dismac case; it is fully functional and complete, featuring a Level 2 restored case, DOS with a full game pack, and a Sound Blaster audio system!

     The PC also comes with a hard drive pre-loaded with DOS and the Brazilian version of Windows 3.11! Plus, it includes an amazing pack of classic DOS games for the customer to enjoy! 

    Although the sound card lacks a CD-ROM controller (as the customer opted not to pay the price difference), it features the famous ♭Yamaha OPL-3 chip, which significantly enhances the audio quality of DOS and Windows games! 

    Gaming with this card offers a superior experience—a privilege enjoyed by only a few collectors in Brazil! This 486 unit was originally acquired from one of our suppliers; however, it lacked an operating system, the hard drive was damaged, and the motherboard wasn't originally a 486. 

    🖳What makes this model stand out is its exclusive DISMAC case, complete with its original serial number! It is a beautiful, stylish case featuring various status LEDs and compatibility with ATX-style boards. Dismac manufactured these computers in Brazil under the "Alphadigital" brand name.

    The computer is assembled and equipped with an authentic Intel 486 DX processor clocked at 33 MHz! It features an ISA-slot VGA card and, of course, a Yamaha OPL sound card (16-bit ISA slot) with drivers that load in both DOS and Windows 3.11! A highlight is the incredible ISA controller card for the hard drive, serial ports, and parallel port—an essential component for the computer's operation!

     To make the package even more complete, this computer is equipped with a 🖬5.25-inch floppy drive—a very rare find in Brazil! It works perfectly, and its LED has been replaced with a new amber-colored one! A new💾 3.5-inch drive was also installed, giving the case that classic 90s computer look! This model—which has already been sold to a Brazilian collector—does not feature a CD-ROM drive! 

    ⓇESIJMJG is a benchmark for vintage computers in Brazil and Latin America! The Brazilian version of Windows 3.11 was installed to run the classic applications for the Yamaha OPL-3 chip sound card and its powerful YStation audio center! 

    🔊With YStation, users could play MIDI music directly from the application! It allows for independent volume control across channels, as well as control over the card's auxiliary (3.5mm) inputs! Users can also access the powerful surround sound processor, creating a truly immersive, spatial audio experience. It is worth noting that the Yamaha OPL3 sound card features an onboard amplifier chip capable of driving passive speakers—just like the multimedia speakers common in the 90s!

    🕪 It delivers powerful, clear sound with bass and treble adjustments, offering the kind of high-end audio quality that defined that era. It is vastly superior to the onboard sound cards that came later, which required powered speakers that were often expensive yet low-quality—a trend that persists to this day! 

    👾The best of the vintage and retro computing world is here at ESI, presented by JMJG! This is truly one of the best computers ever sold to a collector, featuring a solid, high-quality restoration! The computer is equipped with a traditional hard drive rather than the CF cards often used as a modern substitute, ensuring 100% authenticity! Join us in the wonderful world of vintage computing as we showcase unique equipment from Brazil and across Latin America! Stay tuned for more updates!
