+ | The following information is up to date as of December 2017. | ||
+ | |||
+ | The goal here is to have a working external SCSI solution for the X68000. | ||
+ | |||
+ | The instructions below cover both newer SCSI based X68000 machines as well as older SASI based machines. You need to know if you have a SASI or SCSI machine; you should not attempt the SASI instructions on a SCSI machine. | ||
+ | |||
+ | * SASI only steps will be highlighted as such: <color # | ||
+ | * SCSI only steps will be highlighted as such: <color # | ||
+ | * Steps that will be common to both will not be highlighted | ||
+ | |||
+ | |||
+ | __**PreReq: | ||
+ | |||
+ | * SCSI2SD V5.0b (http:// | ||
+ | * 50 pin to 25 pin SCSI adapter for the SCSI2SD (purchase at same time as SCSI2SD) | ||
+ | * (optional) 3D printed case for the unit | ||
+ | * any microUSB 5V cellphone charger to power the SCSI2SD PCB | ||
+ | * 1GB or bigger MicroSD card | ||
+ | * SCSI external cable to connect between your X68000 and 25 pin | ||
+ | |||
+ | The cable is the most difficult part. Some X68000 machines have the original SCSI-1 CN-50 connector. Others use the SCSI-2 external Centronics (MC-50) connector. | ||
+ | |||
+ | Some things to keep in mind: | ||
+ | |||
+ | * The X68000 external SCSI connector follows standard SCSI pinout (even on SASI machines) | ||
+ | * You might have to use multiple adapters (e.g. MC-50 to CN-50 adapter, and then CN-50 to 25 pin SCSI cable) | ||
+ | * The 25 pin end needs to be male. This was commonly used on Apple computer peripherals of that era | ||
+ | |||
+ | __**Software setup:**__ | ||
+ | |||
+ | 1) <color # | ||
+ | |||
+ | * Download the SASI boot disk [[https:// | ||
+ | * write it to 5.25 1.2MB floppy using XFloppy 1.1 in Windows 98 (or find a friend that can create this boot floppy for you) | ||
+ | |||
+ | 2) <color # | ||
+ | * boot the floppy | ||
+ | * At the A prompt type: | ||
+ | |||
+ | < | ||
+ | cd sxsi | ||
+ | | ||
+ | | ||
+ | | ||
+ | </ | ||
+ | |||
+ | * Next, we change the " | ||
+ | * At the A prompt type: | ||
+ | |||
+ | < | ||
+ | | ||
+ | with arrow keys, scroll down to BOOT and press ENTER | ||
+ | Use spacebar to set it to: ROM $ED0100 | ||
+ | - You are telling it to start the SASI boot loader! | ||
+ | Press Enter, and scroll all the way to the bottom | ||
+ | Press Y to save settings | ||
+ | </ | ||
+ | |||
+ | 3) Create Hard Drive image on micro SD card: | ||
+ | * Download WinImage and install | ||
+ | * Download latest x68000 hard drive image from the x68000 FTP site (search for x68000v4.zip) | ||
+ | * unzip drive image and launch WinImage | ||
+ | * Make sure microSD card is now plugged into your computer (e.g. SD external card reader) | ||
+ | * from the " | ||
+ | * select the card reader | ||
+ | * make sure you're able to list all files | ||
+ | * navigate to where you opened x68000v4.zip and select X68000_V4.HDS | ||
+ | * It will take a few minutes to write the image to the micro SD card | ||
+ | |||
+ | __**Hardware setup:**__ | ||
+ | |||
+ | 1) Update and configure the SCSI2SD device | ||
+ | |||
+ | * download the following files from the SCSI2SD web site (http:// | ||
+ | |||
+ | < | ||
+ | | ||
+ | | ||
+ | </ | ||
+ | |||
+ | * scsi2sd-util.exe is a Windows application. If you are on a Mac, download the Mac config utility instead | ||
+ | * connect the SCSI2SD device via a microUSB cable to your computer and launch scsi2sd-util.exe | ||
+ | * from the File menu select " | ||
+ | * select the above firmware file and let it update | ||
+ | * click on "Load from device" | ||
+ | * On " | ||

+ | * click "Save to device" | ||
+ | * click "Load from device" | ||
+ | |||
+ | 2) Put it all together | ||
+ | * 50 pin to 25 pin converter plugs into SCSI2SD | ||
+ | * MicroSD card plugs into SCSI2SD | ||
+ | * SCSI cable connects between X68K external hard drive port and SCSI2SD | ||
+ | * <color # | ||
+ | * <color # | ||
+ | * make sure there is no floppy in X68K and power on the system | ||
