There is a 3-part cable kit that serves all 3 models, and a few different types of 1-piece cables that support 100-only, 102-only, and 102 & 200.
The pics and descriptions on arcadeshopper are wrong, but he has all these 4 types of cable kits (unless some sold out by now), so ignore the site and just specify by email which kind you want: 100, 102, 102/200, or 100/102/200. You'll need a system disk too. There is a disk for 100 and a disk for 100 & 200. If you don't have a 200, don't get the 100/200 version of the disk. It works but it requires a 200 to make fully correct and functional backups of the 100/200 disk. Other than that, it supports all 3 models, so if you have multiple machines including a 200, you can just get the 100/200 disk and use it for everything. Just only use the 200 to make copies. The problem is if you use a 100 or 102 to copy the 100/200 system disk, the copy will only boot a 100 or 102, and won't boot a 200. In that case you should delete the *.200 files from that backup and label the disk as 100. You'll need some 360k double density disks too, NOT 1.2M. -- bkw On Sat, Jan 18, 2020, 5:55 AM Charles Hudson <clh...@gmail.com> wrote: > Thanks to Mike, James, Gregory and Jim for your responses.
