Sharp loves slightly deviating from standards. The disk use signal is sent over Pin 34, at least on the internal IDC drive connector (drive side).
On official ArdSCSIno boards you have two jumpers to select the mode of operation: JP1 and JP2.
JP1 controls whether or not the LED is to be operated on common anode or common cathode. 1-2 is common cathode, and is to be used on SASI machines. 2-3 is common anode, to be used on SCSI machines.
Do NOT short 1-2 on a SCSI machine. Keep this in mind if you use the internal connection. Using a SCSI add-on board counts as SCSI machine, while having SxSI installed or ExROM counts as SASI.
JP2 enables the LED. 1-2 On, 2-3 Off. Simple as that.
On BlueSCSI with the ArdSCSIno firmware, you only have the common cathode LED signal. On a SASI machine, that's all you need, manually connect it to Pin 34 with a wire, if you plan on storing it inside permanently.
SCSI machines, good luck, you will need a way to invert the signal. You can probably figure it out, or patch the software.
Pin 34 is normally floating, but beware of removing the patch when changing machine type.
I recently found a blog post detailing how to use ardsxsino in SCSI mode, but what immediately caught my eye was, instead, instructions for SASI!
Excited, i immediately created a 40MB blank image, plonked it onto the SD card as HD00_256.HDF and immediately whipped out my mas-
Wait a minute... Maybe i should NOT be using ExROM for this. I took the BIOS chips out and popped in a fresh(?) set of XeiJ-IPLs. Ome quick boot to confirm operation, and into Format.x i go.
Formatting the drive took me an embarrassing amount of time due to filename shenanigans, forgetting the terminators or forgetting to disable X1turbo mode in the configuration file, as it doesnt work otherwise.
After formatting, i am asked to reboot to use my fresh new disk. Who am i to refuse? With little hesitation i pushed the Y key, watched the MC68000 powerhouse restart and lo and behold, the barest human.x prompt blinking at me. Success!
Still, with this configuration i am essentially locked out of my SxSI disk images. I copied over the contents of the master disk, effectively making it obsolete, and proceeded to install SxSI.
As SxSI skips drive 0/0, this effectively makes it so with SxSI off i can use a more period accurate, and frankly stabler, drive image, while with SxSI on i can access the collection of the HDD Image V4 and Multimedia Image. In the latter mode, i found i can still access the drive, but one nust tread carefully, as i found myself stuck into address errors. Go figure.
