Look at the design, it screams "IBM".

3513 Enclosure, Rear

Wow. 3.5" IDE HD, not even a 2.5" model... DSAA-3360, 929 cyl, 16 heads, 48 sectors/track. P/N 84G8392. Wow, again. The header is NOT a 40 pin ATA, it uses a fine-pitch cable and the header is about half the width of the normal IDE ribbon cable. Uses the standard 4 pin Molex for power, though.

Note the strain relief between the EMI filter and the back of the enclosure. To easily open the enclosure, the strain relief's straight side MUST be parallel to the upper cover. If it is "cocked" a bit so part of the strain relief blocks the upper cover, it will keep you from sliding the cover rearward.

The strain relief can be easily removed and a whole new cable (for a newer PCMCIA/IDE card?) installed...

I wonder about the need for a PSU, until I get one, it is unclear if this could support a CF card in an IDE to CF adapter. If possible, a solid state CF drive might obviate the need for the PSU.

3513 PCMCIA/IDE Interface Card P/N 40G2894

Note there are two announced HDD sizes, 364MB and 527MB. Unsure if the 527MB size is due to a card limit, available HDDs, or was a limit of the supported system BIOSes... The possibilities of overcoming the 528MB limit might include a drive overlay -OR- swapping out the stock card/cable combo and dropping in a newer PCMCIA/IDE Interface Card that supports the PCMCIA 2.01 spec...

Or if you don't worry about PS/2 systems, you could just find a CardBus card and cable.... (CardBus is NOT supported on PS/2 systems!)
