It's an early 1983, XT clone that came out just before the IBM XT did (from what I've read). Does anyone here have any experience with this particular model of computer or maybe even tried to use a XT-IDE card with one? I want to use a XT-IDE card so I can avoid using the 8 inch floppy's.
I only have two 8" floppy discs for it one of which has occasional read issues so I am afraid to use it because once those discs go I can't boot the computer anymore because I don't have any extra 8" discs let alone spare boot/software disks, and I know most of these are likely on their way out anyway.
I read somewhere (I can't remember where) that while the JB-3000 is a XT clone it was a very early one and might not be entirely compatible and that some 8bit ISA cards that people tried wouldn't work in it.
I can't find any manuals or anything anywhere on the internet either

Here is a 1983 dated review I found on the internet, http://messui.polygonal-moogle.com/comp/national.pdf
