[Arm-netbook] Sourcing PCMCIA type 2 and type 3 cases

[Vincent]

Hi everyone,

I just did a little digging to find suitable sources for these cases.
Since working on the i.MX7-based card, I would really like to tinker
with the cases, too.

Two samples of each type would be nice. Any idea where to get them?
Unfortunately, I could not find a good source.

Thanks,
Vincent

yep. you won't. there's only two that i know, and they're the exact
same part. i was waiting to hear back from you in order to introduce
you to mike (the factory that has the parts), and also waiting to hear
back from you so i can send you the files i've been working on. did
you see the message on this list which was in response to your
introduction about the iMX7 card? i changed the name of the list so it
may have affected any filters that you might have.

Hi Luke,

Hm, that is sad. I somewhat fear that these cases are being phased out
and soon will no longer be available :-/

Does he have both type 2 and type 3 cases? I saw some type 3 cases with
screws and everything which lead me to the conclusion that it could
actually be possible to open/close them and insert/remove the PCB that
is inside? For type 2, this appears not to be possible?

If it is about receiving data, I can basically set up pretty much
everything, e.g.: receive via email, dedicated GIT, anonymous file drop
off, etc. ;-)

Cheers,
Vincent

no - there are at least two big customers still ordering these
specific parts. one is in korea, the other is the french "Conditional
Access Module" industry.

also i've ordered 2,000 of each (case and connector) so should have plenty.

no. type II only.

the litkconn P/N 68F casework basically is a "total disassmbly" job.
it's a pain in the ass and takes several minutes.

Is the pc card's casing this one

yyep, that's the one! it's actually PCMCIA - CAM cards are
pin-compatible and electronically compatible with PCMCIA then they do
this weird flip-over thing... i think. in case you're not aware of
it, PCMCIA is actually... get this... it's the old IBM AT/XT bus!!
isn't that hilarious? CompactFlash is just an 8-bit version of the
same thing, and *both* are *directly* pin-compatible with IDE drives!

which is why you can get a CF-to-2.5in IDE adapter from e.g.
hwtools.net. or, i did 10 years ago, anyway.

...to add my voice, as a retrocomputing enthusiast, because of that and
because I dang well can :P

PCMCIA (which is 16-bit) is adapted from ISA. CardBus (which is 32-bit) is
adapted from 32-bit PCI. (Yes, Virginia, there *is* 64-bit PCI... it's
called PCI Extended aka PCI-X, and is *not* the same as PCI Express aka
PCI-E.) CompactFlash is adapted from IDE. I've never heard of any
PCMCIA<->CompactFlash interoperability that didn't need a translator
("bridge") chip in between. "PC Card" refers to *both* PCMCIA and CardBus
at once, because people these days are brought up too badly to remember a
five-letter freakin' acronym, and all three names (and both standards) were
from the same committee/commission/group, which was *also* named PCMCIA.
Past tense here, because in 2009 it became part of USB just to confuse
everyone even more. CompactFlash, on the other hand, is SanDisk's baby.

Also, PCMCIA is not interoperable with CardBus, electrically and (due to
the connector notching, which is upside-down from one to the other)
physically. If you don't see the little gold stripe near the connector, you
have either a 16-bit PCMCIA card or a *really* early (or equally cheap!)
32-bit CardBus card. Chances are pretty high that it's the former and not
the latter.

The XT Bus is 8 bits only, and is *very slightly* different from 8-bit ISA
(please don't ask, I don't remember the specifics offhand). I would
*assume*, although I don't actually know, that the AT Bus and ISA-16 are
similarly slightly different. Oh, yeah... if you just say "ISA", you're
probably thinking of ISA-16, which was rather a bit more popular. There is
8-bit-only ISA, just ask half the slots in my old 386 ;) Before anyone
strikes up an argument, I *do* have a PC-XT clone in addition to the
previously-mentioned 386 (which was my first computer, three rebuilds ago),
so I'm in a position to know about buses... I need to burn a BIOS chip for
it because known-good floppy drives don't work in it right now... haven't
gotten around to that yet, though, mostly because UV erasers for EPROMs are
relatively expensive at my income bracket.
