But if you have the boot disk (I think I do) and the 8431A disk drive (I don't) for the NEC-PC-8500 it should be able to boot into full 64K RAM CP/M mode. Which would improve compatibility with typical Z80 CP/M software. -- John.

That is rare! I was looking for the 8431A at one time because the PC-8500 needs it to boot into all-RAM CP/M mode. Gave up. -- John.
[M100] NEC PC-8231A on eBay
One was posted today. It is listed as as-is/untested with a broken clip. Seller is asking $199 for it. I bet someone on this list will be looking for one. https://www.ebay.com/itm/333608993347
