There is one thing where the newer version is better: correctly recognizes >16 MB of memory.
Still only allows to test 16 MB, though.
And can't forgive the hanging "Interrupts".

Overall, 3.00i still seems the most reliable.

Ok, I just checked my version of CheckIt 3.0 and in CHECKIT.EXE I found this string: "CheckIt 3.01k, 01/30/91". The executable itself is 330709 bytes. So we have more than two versions of CheckIt 3.0 😁

P.S. CHECKIT.OVL also varies in size between the different CheckIt 3.o versions.

Yes, larger CHECKIT.EXE = smaller CHECKIT.OVL
Obviously they moved some code between those files.

Correct.

But there is also another difference unrelated to executable files: help file varies in size too 😀

You mean CHECKIT.HLP, right?
Strange, it's exactly the same in 3.00i and 3.03C...
perhaps your version isn't in English?

Yes, I mean CHECKIT.HLP and my version of Checkit 3 is in English too, but as I mentioned, a different revision 3.01k. Of course, the help file has no impact on the stability of the software.

P.S. Ok, I compare my files to some 3.00i versions circulating on the web. I can't find version 3.03c for comparison.

I also have a version 3.00j which has all files identical to 3.00i except for the main EXE has a couple small changes. Dated 9/12/90
