Just ran across a box I thought had nothing but blank 8" diskettes and found instead 7 diskettes, labeled "TX990/TXDS Release 2.0"; diskettes 1-5, with what appears to be dupes of diskette 2-4. All are stamped "Property of Texas Instruments Incorporated" "(C) 1977, Texas Instruments Incorporated" Are these worth anything or can they be tossed into the "reuse" pile? I haven't tried reading them yet. Cheers, Chuck
