Almost all that I have uncovered so far are in lightly "textile" feel boxes.
The boxes are 9 1/2" x8" deep x 2" wide with the IBM logo on one side of the silpcase
The actual pages are about 5 1/2" x 8 1/2"
The first one I found was VisiCalc ;-) IBM P/N: 6024004 with the vinyl holders loaded w/ Visicalc on 5 1/4" disks.
Seems like that one should be worth ~$2.5M just by it's self??? yeah? right?
