[edit] Mirror Vax

There isn't any firmware on the Disk II controller card that resides in the Apple's slot. Are you talking about the firmware in the Apple II ROM itself then?

Also, why delete the reference to DOS.MASTER? --PZ 18:37, 15 March 2006 (UTC)

• PZ, I reverted that user's edits - they seemed odd and were not explained. By the way, thanks for your edits to this article. — Wackymacs 19:35, 15 March 2006 (UTC)

You added "...inside the drive" which turned the statement into nonsense. The controller card was not inside the drive, and nothing changed in the drive. The "see also" you added has low relevance to this article. I did vote "keep", incidentally. Mirror Vax 19:47, 15 March 2006 (UTC)

The article states "depending on the firmware revision of the controller card". I know that there is no firmware on the disk II controller. So it either needs to reside on the Apple II motherboard in ROM or on a ROM INSIDE the Disk II. (I have never taken a Disk II apart, so I don't know for sure if there is a ROM on the controller inside the drive) - I assumed that this is what was intended by the statement "firmware revision of the controller card" since there is no ROM on the Disk II controller. I'm just trying to clear things up because its confusing right now as it stands. btw: thanks for the "keep" vote on DOS.MASTER. --PZ 20:10, 15 March 2006 (UTC)

There are actually two ROMs on the controller card, the boot ROM and a state machine ROM. Mirror Vax 20:22, 15 March 2006 (UTC)

Dag nabbit - you're absolutly right! There's two 256 byte 6309 PROMs on the Disk II controller card that look like standard TTL ICs. I appologize for the confusion. --PZ 20:57, 15 March 2006 (UTC)

[edit] Floppies

were these supposed to use SSSD or SSDD floppies? Is it worth mentioning that it was incredibly popular to notch the other side of the disk such that the back side could be used as well? Many commercial applications shipped with software on both sides of the disk like this. TimRiker (talk) 18:03, 21 February 2008 (UTC)

Disk II compatible 5.25" floppies were single sided, single density — or of course double sided if you wanted to flip it over and use the other side too. I don't have a reference for this; it's personal knowledge. --Closeapple (talk) 14:28, 22 February 2008 (UTC)
