Hi,

> an odd thing, when I downloaded I am getting a verification error on byte 0000.  I honestly do not know if I was receiving that error yesterday, I was so excited that I finally got the download working that I may have missed that error.  I do not know if it is the only mismatch or if it stops checking after the first mismatch.  nonetheless, the RCT seems to be working ok as far as I can tell.  any suggestions?

the verification error at address usually means that the firmware has 
not been correctly flashed (usually the first 128kb are overwritten by 
the next 128kb -> 128kb bug that is known for USBASP devices).

When it works be happy. When you later see crashes etc. you should 
reflash the firmware.

> The loop 11 works well (once I realized I need to do a long press on OK) but it would be nice if you could add the all illuminated to the characters since some pixels are not illuminated with the existing character set displayed.

Ok, I will check which segements are missing -> TO DO list

> another question: when testing logic devices and a configuration fails, does it stop testing or continue with all configurations? is the display showing us the first failure?  is there a way to see all the failures?  I have not found in the manual where logic test results can be downloaded to the SD card like PALs and PROMS, can logic test results be download also?

The test stops with the first error detected. There is currently no way 
to see all errors. Logic tests are not saved.

Regards,
Stephan
