CD-ROM Emulation Introduced on ISA Bus by PicoGUS
In the realm of retro computing, the PicoGUS 2.0 ISA card has recently made a significant impact with its innovative ability to emulate proprietary CD-ROM drives. This small, yet powerful device, originally introduced as an ISA sound card, now offers a unique solution for retro PC users who face the challenges of aging optical drives.
One of the standout features of the PicoGUS 2.0 is its CD-ROM emulation capability, which allows it to act as an optical drive emulator (ODE) for retro PCs. The device supports image formats like ISO and BIN/CUE from a USB drive plugged into its USB port. With two modes for CD-ROM emulation - Sound Blaster and USB - users can enjoy CD audio, CD-ROM, and even MPU-401 emulation, with speeds up to 4 times that of a standard CD drive.
The Sound Blaster mode, while offering CD audio and SB DSP support, can cause stuttering due to high demand on the Raspberry Pi Pico embedded within the card. In contrast, the USB mode offers faster speeds with less demand on the Pico, but requires a separate sound card since it does not emulate sound itself.
The PicoGUS 2.0 also emulates various sound cards, including Gravis Ultrasound, Sound Blaster 2.0, MPU-401 for MIDI, Tandy 3-voice, and CMS/GameBlaster. This makes it an ideal choice for retro gaming enthusiasts who seek authentic sound experiences alongside their CD-ROM emulation.
Interestingly, the PicoGUS 2.0 is currently the only known ISA card supporting proprietary driver board CD-ROM emulation, according to the latest research. Unlike traditional ISA sound cards with CD-ROM interfaces, the PicoGUS 2.0 emulates the drive itself, setting it apart in the market.
Moreover, the USB stick connected to the PicoGUS 2.0 can function as a CD changer, allowing access to multiple disk images. This feature is period-appropriate for a DOS box and adds convenience for users.
Setting up the PicoGUS 2.0 requires open-source utilities and appropriate drivers. Users can select disk images with utility software on the PicoGUS 2.0 and enjoy the benefits of its game port support.
In a world where vintage optical drives frequently fail, especially moving parts, and original CD media isn't always easy to find, the PicoGUS 2.0 presents an attractive solution for retro PC enthusiasts. Its fast performance, CD-ROM emulation, and sound card emulation capabilities make it a valuable addition to any retro PC setup.
