Hi Thomas,
Do you happen to have also the original SHARP MS-DOS 2.00 disks? It may
have come with the CE-510F.
All my bubble cartridges have MS-DOS 2.00, and one of the cartridges has
SYS.COM. So... I did a FORMAT /8 on another x86 system and formatted a
320KB disks. Then I put that disk into the PC-5000, then did a SYS C: from
the bubble cartridge that has SYS.COM, and it said "System transferred"
(and CHKDSK.COM agrees, there are 2 hidden files). I added COMMAND.COM to
the disk, but it (the PC-5000) still won't boot from that disk. I turn
the system off, remove the bubble cartridge, power on the system with this
"new" 320KB disk inserted... and it says WARNING: NON-SYSTEM DISK.
So we'll be hunting for an original SHARP PC-5000 boot disk still.

Sharp computers from the early 80's were truly
amazing. Every computer
part they produced was a joy to see and feel because of its accuracy and
design. If you've ever held a Sharp CE-152 data tape device, you know
what I mean.
Fortunately, I have a CE-510F with an internal power supply and floppy
disk controller.
If you're interested, please drop me a PM.

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).
Thanks!
