@Amiga4k,
The sticker says Panasonic. Below that are two lines with some information. The first line reads "Model JU-253-233P" and the next line reads "C A3050 011563". The "A3050" part is in stamped ink that's starting to rub off.
I can see where three jumper pads should be. The entire pad is covered with a black piece of maybe plastic. The black piece is in turn covered with a piece of metal across the whole pad.
From left to right, the three pads:
"0 3 2 1" , "MO SW2 MS" , "RY SW1 DC"
It does not appear as if I can change any of those, and I don't see how I can tell which setting it's set to.
It did come from a used 4000D. It's possible a previous owner kept the HD drive and threw something else in there, or maybe it came like that originally. I kinda doubt it originally came that way since it's a half-height drive and there is a bit of an empty gap when its fitted to the case.
The 4000D began life as a 4000D/30 but when it got to me, it had a 3.0 modded to rev 3.2 A3640 with 68040/25 onboard and 16MB fast ram.
Hope this information helps, and if there's anything else you want me to look at on this drive let me know.
