When some people think "clone", they think "compatibility" which leads to the following differences:

Excerpt:

"In May 1983, Future Computing defined four levels of compatibility:[11]

Operationally Compatible. Can run "the top selling" IBM PC software, use PC expansion boards, and read and write PC disks. Has "complementary features" like portability or lower price that distinguish computer from the PC, which is sold in the same store. Examples: (Best) Columbia Data Products, Compaq; (Better) Corona; (Good) Eagle.

Functionally Compatible. Runs own version of popular PC software. Cannot use PC expansion boards but can read and write PC disks. Cannot become Operationally Compatible. Example: TI Professional.

Data Compatible. May not run top PC software. Can read and/or write PC disks. Can become Functionally Compatible. Examples: NCR Decision Mate, Olivetti M20, Wang PC, Zenith Z-100.

Incompatible. Cannot read PC disks. Can become Data Compatible. Examples: Altos 586, DEC Rainbow 100, Grid Compass, Victor 9000."

So what type of a "clone" are we talking about?

I don't work for the company that makes the kit, and as far as I can tell prima facie, their kit is a faithful reproduction of the reference IBM PC hardware design.

I may be wrong, however.
