Hi all, Sharp's HB-3600 disk drive interface supported up to two drives and came with two disquetes. I did dump the BIOS and the disks in one package,
- Disk BIOS interface (Sony HBD-F1 compatible) - HB-DOS v1.2 (MSX-DOS compatible) - HB-MCP v1.1 (CP/M compatible) - Installation Manual Scan - XML files for emulating the interface on openMSX The most interesting and rare item of the bundle is the HB-MCP. This as a CP/M operating system developed by EPCOM, the Sharp's division for homecomputers. Since it does direct access to the FDC, it is very fast. But as a downside it will run only on 100% compatible interfaces, like the Sony HBD-F1 and there must be no other disk interfaces connected to the MSX. Its also curious that the HB-MCP do support the MSX2, even if Sharp had never released an MSX2 Hotbit and their 80 columns card (V9938 based) used the secondary set of VDP ports. The HB-MCP also supported an external pain 64KB RAM expansion produced by Sharp. You can try it on openMSX. Just select any diskless MSX1 or MSX2 and the HBD-F1 or the HB-3600 disk interface. http://frs.badcoffee.info/raremsxsofts.html You can see the HB-3600 on the left side of this picture: http://www.msxarchive.nl/pub/msx/photos/hardware/Sharp_HotBit_HB-8000_1.2.jpg Best regards, FRS _______________________________________________ MSX mailing list (msx@stack.nl) Info page: http://lists.stack.nl/mailman/listinfo/msx
