because I have the bubble memory card for the T-3, and would like to be able to use it. It is recognized but gives me an error on the memory size. #480 and #494. The batteries were dead when I installed the card, so it may also need formatted. This particular QT did not come with the bubble memory option. I added the card.
I have a perfectly working Blue box. But would like to have the bubble option, so I don't have to constantly use the Disk drive to reload programs.
Bubble memory holds more than 1 disk, and is faster and easier.
