WORK IN PROGRESS
SCSI Cable
SCSI cable with male-male HD50 connectors, usually 2-3 meters long (6-9 ft).
Example of shop that is still selling new cables: Winford (USA)
Connected between the "SCSI-A" port on the devkit and the SCSI pci card on the PC.
SCSI Terminator
2 Active SCSI terminators with HD50 male connector, to connect to the "SCSI-B" & "For GD-WRITER" ports.
SCSI Card for the PC
Recommended hardware according to the SDK: Adaptec 2940U SCSI PCI
Compatible hardware:
- AHA-2940 - 10 Mbytes/sec max card
- AHA-2940AU - 20 Mbytes/sec max card (Note that due to the devkit limitations, you will not read those speeds, but the transfer speed seems to be a little bit more stable with this card)
- Adaptec SlimSCSI 1460 PCMCIA - revision 'D' - confirmed by Dreamcast in the post below.
- Adaptec USB2Xchange - tested OK by Dreamcast on a real Windows 98SE installation, cfr the posts below. Windows 98SE in a VM has problems though.
- basically, any SCSI card with external HD50 connector should do, but the 2 cards mentioned above have a Windows7/10 driver, cfr other post in this forum.
- Avoid Adaptec 2940 SCSI cards with a W or UW (eg 2940UW), those do not have a HD50 connector, so you will need an adapter & test it for yourself to see if it works. The SDK mentions also the 2940UW though (with adapter).
TODO
C1/C2 Cable
TODO
Extension Cable
TODO - probably this cable, but not tested yet
Video Cable
On a SET5, locate the 4 dip switches on the front panel marked as "DIP SW".
The 2 most left switches select the video output (from left (SW1) to right (SW2)):
- VGA output connector: SW1 UP, SW2 UP: regular VGA cable
- RCA (yellow) connector: SW1 DOWN, SW2 DOWN: regular composite (RCA) cable
- S-Video connector: SW1 DOWN, SW2 DOWN: S-Video cable
- (? not tested) VGA output connector to (?) SCART: SW1 UP, SW2 DOWN: RGB output (NTSC/PAL) - custom cable ?
Midi Cable
TODO - explain self-test
Harddisk
Original hardware: Seagate Medalist ST34520N, 4.55 GB - 8bit data bus - 5 to 10 Mbytes/sec
(TODO: add notes about formatting & partitions)
Replacements:
- SCSI2SD SCSI-SD adapter:
V5.0a - confirmed by T_chan. File transfer speed: 1.3 MB/s
V5.1 - confirmed working on a SET4 by Jackhead.
V6 - early revisions / firmware might have issues. Tested by Sizious, who worked with the creator of SCSI2SD to fix this.
V6.02 - confirmed working by Sizious. File transfer speed: 2.3 MB/s
TODO: settings and speed test - CF AztecMonster SCSI-CompactFlash adapter: (obsolete). Tested by Jackhead - working.
- SD SusanoMonster SCSI-SD adapter: replacement of the CF AztecMonster, but nobody has tested that yet with a Katana devkit.
- AztecMonster II SCSI-SATA/SSD adapter: (obsolete). I couldn't make this work with the devkit, might need to test more in the future.
- ARS-2000SUP SCSI-SATA/SSD adapter with frame: expensive, but working (I tested it with a recent Samsung SSD), and it comes with a nice metallic frame that fits the devkit perfectly. Don't hope to have any speed advantage compared to the SD/CF solutions though, the devkit seems to be the limiting factor.
GD-ROM drive
The GD-ROM drive of the Katana devkit can be replaced by the GD-ROM drive of a normal dreamcast. The cables are somewhat shorter on a normal dreamcast, but that isn't a problem.
GD-ROM drive latch
Original hardware: TODO
Compatible hardware: Self-test chip
Original hardware: ST M27C160-100F1 16Mbit UV eprom from STMicroelectronics
This eprom can be physically removed from the devkit, and erased via UV light, and reflashed via a universal programmer like the TL866/TOP3100 (TODO: check compatibility)
(TODO: normally not reflashable via SCSI, only the bios/flash can be reflashed via SCSI ?)
Front Panel - Rotary Switch
Original hardware: Rotary DIP Switch JAE 42J 34GT-E
Power Supply
Original hardware: Bestec Power Electronics Corp Model ATX250
Replacements:
- JAE rotary dial switch, 16 bit 0-F rotary encoder switch, 1238 C positive code (found by Chacal on assemblergames)
- JAE rotary dial switch, 16 bit 0-F rotary encoder switch, 1238 C positive code (found by Chacal on assemblergames)
