Looking for Sanyo MBC-200 system discs (or maybe 1200?)

I have a Sanyo MBC-200 but no system discs, and have spend ages trawling the internet for them, even searching for sites in Japanese!
The only person I found who had some sadly died a while ago.
Can anyone else help out. (I have looked the the sticky link above but found nothing).
The MBC-200 is a dual Z80 machine, so I think it'll be compatible with the MBC-1200
 
Please do. I have started working on emulation of MBC-200 machine, and so far I have found that
HD46505SP (MC6845 clone) is mapped at 0xb0, 0xb1 ports and one of 8255 is mapped at 0x70-0x73

IPL code start looks strange since there is no disable interrupt at begining, so I have to analyze code more.

When I come to point of booting, there will be also need for floppy image, so it would be good if it's found.
 
Yes, it would be great if I could get a disk image.
Micko is writing an emulator for the machine, and I have a non working machine, neither of us have the software.
 
Okay, I've found copies of 1200 and 1250 boot disks.

But before I email things--isn't there some depository of these images that I can simply ftp to for uploading? Sure as the sun will rise tomorrow, I'm going to get yet another request down the line for the selfsame disk.
 
I hear crickets.

Does anyone wonder why I don't offer boot disks from my library? This entails searching through a couple thousand disks, verify the contents, prepare the image, do a trial extraction to a floppy and verify that it looks okay and then finally prepare the ZIP archive for image and move it over to a net-connected system. Scratch an hour and a half of time.

More often than not, I get return emails saying "How do I extract the image" or "I don't have a 5.25" floppy drive" or "Why doesn't ImageDisk work on Windows XP?" or "My system still doesn't boot."

Now you know. Don Maslin was a saint, in my humble opinion.

Hi Chuck,

Idea we are working on MESS is to prepare a softlists for computers we emulate so you have system software and so on. We would be happy to distribute files if you agree. We are working on lot of systems, but also things we provide are share quite fast so could be a good way to preserve things.
Understand issues you have with people but if images are booting in emu, it's always nice to have it as reference and
proof it is working fine.
Anyway for CP/M systems IMD format is fine, TD0 too, we are also working on support for flux dumps (as with KryoFlux) for protected disks, and some test cases work just fine.
 
Just tell me where to send the thing.

I don't care about emulation (at least not for personal computers; however, if you have a Fairchild Sentry 70 emulator, let me know).
