| - | ====== X68000 - Writing 5.25" Floppies in Linux ====== | + | ====== |
| + | |||
| + | The Sharp X68000 has two 1.2MB 5.25" floppy drives (except the Compact models, which have far more common 3.5" drives... though virtually no software was released on that format!), so getting a PC with an equivalent drive is the easiest way of getting software or an OS onto them. | ||
| + | |||
| + | ==== Hardware ==== | ||
| + | |||
| + | You will of course need a 1.2MB Double-sided, | ||
| + | |||
| + | Configuring the drive may be the most difficult part of the process - 5.25" floppy drives are nothing near as standard as the 3.5" drive, and you will likely have to find the manual for your model to correctly jumper it as your drive A: or B: - remember that if you have a twisted-ribbon floppy cable, anything before the twist is drive B:, anything after (the end connector) is drive A:. //Your drive jumpers must match that//. | ||
| + | |||
| + | I'm using a **Panasonic JU-475-5 AKO**, a relatively common (and later) drive, but there are similar models from Mitsumi and TEAC. Expect to pay £60 - £100 for a working drive from Ebay. These things are getting quite scarce now. Do not buy an earlier Double-density drive! | ||

| + | ==== Software ==== | ||
| + | |||
| + | You need a package of tools called `fdutils` installing, this includes things like ' | ||

| + | To set up the drive for the Sharp X68000 track layout, you need to configure the drive. Here's a quick shell script that automates it: | ||
