PET IDE Harddisk and Serial Interface: Progress: Pictures !!!

PET IDE Harddisk and Serial Interface

A hardware interface between a Commodore PET Computer (such as the CBM 8032) and an IDE disk drive (with a bonus serial interface). Unlike other approaches, this interface does NOT require a PC or other computer that emulates a hard disk, instead a real IDE drive is connected directly (through the interface) to the PET/CBM, and no special software needs to be loaded into the PET since the interface emulates a standard Commodore disk drive. A serial interface is also provided.

Progress: Pictures !!!

Here are two pictures of an early prototype.

The red LED in the corner beside the IDE connector is a harddisk activity indicator. The IDE connector is just like you'd find on a PC motherboard, it connects to the hard disk drive with a straight 40-pin ribbon cable.

The power connector fits a standard PC Power supply.

The RS-232 port (no handshake lines, just Transmit, Receive and Ground) is a 9-pin female connector

The IEEE-488 connector hooks up to the PET/CBM, of course. It is just like the connectors on the back of an 8050 floppy disk drive or similar.
