Memory error (the floppy is OK, though). Had to have been 73 or layer, because I met the friend who identified the opportunity in '73. Was before '75, which is kinda "c1971" :-) That 8008 system was some kind of "intelligent" workstation, and I got it after it was "retired" by something newer and more suited to the "unskilled" clerical users. I think it did mailmerge letters originally, but I swapped its Eproms to diagnostic ones that allowed me to write assemply language programs to do my stuff... which was business stuff for my sideline business. Kept it and its I/O Selectric in service as a as a business quality printer. Had it about a year before I got my Sol-20 which had been out roughly 6mos to a year before I bought. > > Here's a list of some disks and when they were introduced: > > http://en.wikipedia.org/wiki/Floppy_disk#Disk_formats > > I'm surprised to see how early some of these came out.

Group and bulk buys were certainly important then, but I don't remember ever paying as much as $10 each. $3 was "good". Chuck
