Yes, thats the GQ-4X - I have had one of those and its not comparable at all.
Once you purchase all the adapters, it came to around $400 (which I had). Also, the adapters are specialised. The ones for my new programmer are much cheaper than the willem adapters.
However, it cant do NAND at all and doesnt support a lot of chips I use - hence the upgrade. Its also extremely slow (but better than the parallel ones at least).
If you check the mcumall forums, you will see I am a regular poster there still

The MPT-1020 is a rebadged Leaper 48:

My current programmer (thinking about another upgrade!) is:

So its most likely advanced enough to be doing device insertion tests etc before read/writing. This is probably why you had issues and is what I described earlier. You should have no problems (but I am downloading the programmer software now to see what options are available to you!).
Edit2:
Select device as MX27C2100 (DIP)
Parameters-> Common Setup
Untick "Insertion Test When Any Action" and "To Check IC ID-CODE When Any Action" and it should read the kickstart maskroms just fine
