A few (Official) DC Development Hardware Questions

Greetings there fellow members,

I wasn't sure if this thread should belong in this forum or somewhere else.

I was wondering are any people here familiar with the official development units used by Sega and developers for the Sega Dreamcast?

I have come up with this list:

HKT-0100: Sega Katana Development Box
HKT-0120: Sega Dreamcast Development Box (Set 5.24)
HKT-0300: Sega Katana Sound Box
HKT-0400: Sega Katana GD-Writer (Firmware 0.54)
HKT-0600: Sega Dreamcast GIGA BYTE DISC RECORDABLE (Orange)
HKT-0600: Sega Katana GIGA BYTE DISC RECORDABLE (Blue)
HKT-0910: Sega Dreamcast SYSTEM-DISC 2

Would anyone happen to know what the HKT-0200, HKT-0500, HKT-0700, and HKT-0800 were, perhaps an Ethernet Broadband box was among them? Would anyone know what HKT number was assigned to the Dreamcast Address Checker hardware?


Also, if anyone has ever laid their eyes on the box of Sega Dreamcast Dev Box, would you happen to know what the HKT-0110, and HKT-0130 check boxes were for on the box?


Any help would be greatly appreciated!

Cheers,

Mark
