PolySCSI - Computer storage emulation (Hard drive)

The Polykubos PolySCSI is a storage device emulator capable of simulating a hard drive, floppy drive, or CD-ROM drive.

The PolySCSI connects to retro computers either internally or externally (optional adapter required).

Internal connection (may require a conversion ribbon cable):

• On Sharp X68000 (models that support an internal hard drive), excluding the Compact version, with an optional mounting bracket — conversion ribbon cable required, not included.

• On Macintosh LC series

• On 386/486/Pentium/... PCs equipped with an internal SCSI port or an Adaptec-type SCSI controller

External connection via the optional adapter (Centronics 50):

• On Sharp X68000

• On FM Towns II UX series

• On FM Towns II with Centronics 50

• On PC-88 (with a Centronics 50 SCSI card)

• On PC-98 (with a Centronics 50 SCSI card)

Extras :

• Optional Centronics 50 adapter (for external connection).
• Optional mounting bracket for the Sharp X68000 (for installation in models that support hard drives, excluding the Compact version).

To simulate a SCSI hard drive:

1. Transfer a disk image compatible with your target system (you can create one using an emulator like XEiJ for the X68000, or download an existing one online) onto a microSD card.

2. Name the file with the .HDA or .HDS extension to make it recognizable as a hard drive.

3. Plug your PolySCSI into the machine.

Using PolySCSI on a Sharp X68000 with SASI requires installing the SxSI driver (available on the Human.sys 3.x floppy disk).

PolySCSI is also SASI-compatible (for use on Sharp X68000 without installing the SxSI driver). Simply name your image file with the .HDF extension.
Note: SASI has a virtual disk size limit of 40 MB.

Powered via the SCSI port (if power is supplied by the host machine) or externally via the USB-C port
