A BIG THANKS to GunRunner John. I finally installed the latest version of Legacy. I had delayed to see if there were issues, but decided that since I had done some ER upgrades, I needed to take advantage of the R100 configuration. Had been using 1.3
Also, wasn't sure IF I wanted to attempt the Black module modification. I DID and it went in flawlessly! As was mentioned in the thread using a single edge razor blade was the easiest way. Opening the Blue module was indeed the most difficult part. THANKS for providing the information!!
(If anyone needs the info on how to modify your existing Legacy Blue modules to the "Black" memory module, do a SEARCH for "Free Black Module" and you will find the info, including pictures.)
