Taken from the original now-defunct MAG website:

The Memphis Commodore Users Club (or Users Group, MCUG) started in the early 80s and lasted until the early to mid 90s. It spawned the Memphis Amiga Group (MAG) as a SIG in the late 80s. MAG operated from the late 80s to the late 90s. Commodore's demise in 1994 took the wind out of the group, and after a few more years it faded out of existence.

Meetings were held monthly, and most were preceded by a board meeting the week before.

These "disk mags" hold bits and pieces of history pertaining not just to MCUC and MAG, but to personal computing (particularly with regard to Commodore computers) in general.

Based on the disk numbering, the collection appears to be lacking disks even when almost every month is represented starting in 1988. Apparently many months would include multiple disks, but often only one survived. 

From AmigaLove: 

Easily one of the most comprehensive and coolest user group disk mags I've come across. Days/Weeks/Months of fantastic Amiga-focused content can be explored and discovered here. 

Currently shown: 

1987 (1 disk)

1988 (14 disks)

1989 (12 disks)

1990 (8 disks)

The remainder of this collection will become public in spring of 2025.
