ST506 interface | Vintage Computer Federation Forums
The elusive debug commands you speak of are not specifically for the ST506 interface, it was firmware added to 8 bit cards for the old XT generation machines which didn''t have any hard

Whence IDENTIFY DRIVE? | OS/2 Museum
As most everyone knows, the AT Attachment standard (informally known as IDE) started by literally bolting the previously standalone AT disk controller onto a MFM drive with a ST506
Replacing ST-506 MFM Drives with IDE or Flash
The interface to clone/emulate the drive is all Linux command line based, and it takes multiple steps to get it configured and there is currently no GUI or even text based unified interface.
ST506 is possible · keirf flashfloppy · Discussion #644 · GitHub
ST506 is the common interface name used by "RLL" HDDs before IDE took over. It is very similar to floppy signaling, but is 5 MHz data rate (MFM is 10 MHz). Since the microcontroller on
Nerdly Pleasures: Working with ST-506 Interface MFM Hard Drives
The ST-506 was a 5MB drive and used a two-cable interface. The IBM original controller only officially supported one type of hard drive in its first two iterations, the ST-412. The ST-412 functioned like the
ST-506/ST-412
Likewise a few early IDE drives were just drives with an ST-412 interface attached to a controller board or chip. Ultimately all SCSI and ATA drives had built the controller into the drive, thereby eliminating
ST506 to CF or IDE or anything
Long answer: Yes, but it''s expensive. ST412/ST506 are more like "analogue" connections. The actual MFM/RLL HDD controller you have in PCs is a WD1003 compatible.
MFM vs IDE hard drives
IDE was an acronym for Integrated Drive Electronics. The earlier standard, which we colloquially call MFM but would more properly call ST506, put most of the drive control logic on the
The IDE Hard Disk Drive Interface
The IDE interface supports up to two drives on its 40-conductor cable in daisy- chain fashion. The primary drive, drive 0, is referred to as the master, while the secondary drive, drive 1, is the slave.
S100 Computers
Here I wish to describe a S-100 prototype board I constructed that allows one to interface the S-100 bus with a standard IDE drive interface. This increases tremendously the range of drives
