Softdisk (ISSN 0886-4152), originally Softdisk Magazette, was a disk magazine for the Apple II computer line, published from 1981 through 1995. It was the first publication of the company that was also known as Softdisk, which would go on to publish disk magazines for other systems, other software, and later be involved in Internet access, hosting, and development.
The brainchild of Jim Mangham, who then worked at the LSU Medical Center in Shreveport, Louisiana, Softdisk (originally intended to be called The Harbinger Magazette, but launched as Softdisk Magazette, with "magazette" being a portmanteau word combining "magazine" and "diskette") was published out of Mangham's house, with his then-wife Judi Mangham, LSUMC co-worker Al Vekovius, and Softalk magazine (a paper magazine for the Apple) as partners in the venture.
The first issue was published in September, 1981, and consisted of a single 5.25" floppy diskette which could be flipped over to get to content on the back side. There was fairly little content on the first issue, and it was mostly repeated on the second issue, so later when issue numbers were retroactively assigned for the purpose of back issue sales the October, 1981 issue was designated as "Softdisk #1", with the preceding month's issue considered either "#0" or unnumbered.
Originally, the subscribers had to send back the previous month's disk when the following issue was received; reusable mailers were used for this purpose, with a postage-paid return address label on the flip side of the address label used for outbound mailing, which was inserted in a plastic Ziploc baggie on the outside of the mailer so it could be reversed by the recipient. This disk return requirement was due in part to the fact that floppy disks were more expensive in those days and needed to be reused for economy, but was also designed to allow the subscribers to participate by leaving feedback electronically on the returning disks, as well as article and program submissions.
