[cctalk] Looking for Sharp PC-5000 disk drive (CE-510F or possibly MZ-80B)

A while back I started studying more about the Sharp PC-5000 (and had it up and running at VCFSW in 2023). I'm now coming back to that project, and one thing I was never able to find was a compatible 5.25 disk drive. I've collected some information about this system at here: https://voidstar.blog/sharp-pc-5000/ And I am hoping to put together a video about out. But one challenging aspect is that its LCD screen is difficult to record (lots of reflections). And despite having lots of schematic documentation now, I'm still not savvy enough to try to export its screen content to an external device that might have a backlight. From my notes, as I recall.... The 37-pin connector at the back of the PC-5000 is not the same as the 37-pin connector at the back of the IO card with the original IBM PC 5150. I believe the Sharp product model number I am looking for CE-510F (which might be the same as MZ-80B in certain markets). This isn't an urgent thing - the Bubble Memory modules of this PC-5000 are still all working fine and make the system functional. But I do have a set of disk with the system that might be interesting to try out. So just broadcasting here, on the off-chance someone might be familiar with these and know of a stash of accessories (most likely within a Japanese-speaking community, where I think Sharp products were generally more popular).
