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
