Quick post from my phone -- existing PCMCIA card cages from random laptops
are a dime-a-dozen on fleaBay, if you want to go that route. They would

Post by PiÄugins ArsenijsPost by r***@Safe-mail.netThis post is about modifying an asus eeepc 7inch notebook into accepting
a pc card. You are invite to contribute.
For your information, I am in a censorship dispute with lkcl. I do
not know what he will come up with. Maybe some or all of my
posts will be stopped.
I'm going to get an EEEoma Wiki up in the following week and start
documenting everything there; if you end up losing posting privileges, feel
free to email me directly.
Post by r***@Safe-mail.netI do not follow lkcl's opposition on this.
He's trying to make sure that the resulting design is safe and 1) won't
ruin reputation of EOMA68 2) will be a good reference design for other
designers that want to make EOMA68-compatible things, so that their designs
won't ruin the EOMA68 reputation.
Post by r***@Safe-mail.netIt is a weller sp 40l 40w.
It seems to have a wide tip, so I'm wondering if it's suitable for
soldering things like a 0.8-pitch connector... We'll see. At worst, you can
get a working soldering iron for $5 from China, and a set of good tips for
$5 more.
Post by r***@Safe-mail.netIn case I did not mention it before. I have a raspberry pi 0 and
a beaglebone black revision c if that could be useful.
Those could be useful for testing, I think.
Post by r***@Safe-mail.netI still have the asus eeepc's mainboard.
That's great =) So we likely can harvest a couple of chips from it if necessary.
Post by r***@Safe-mail.netThe pocketchip's keyboard is an i2c keyboard. Is the asus
eeepc's keyboard also an i2c keyboard?
The pocketchip's keyboard, just like the EEE PC keyboard, is not I2C by
itself - it's a key matrix, and there's usually a controller that connects
to this key matrix. In PocketCHIP's case, it talks I2C - in case of EEE PC,
that controller is a part of Embedded Controller on the EEE PC mainboard
(which controls a whole load of functions), so we're making our own
controller by taking a microcontroller, putting it on a board with a 28-pin
connector and writing a firmware for it.
Post by r***@Safe-mail.netInstead of
modifying the asus eeepc's keyboard into an usb
keyboard, what about i2c connecting the keyboard to
the pc card?
Either that, or use PS2 - since we likely will have a PS2-USB chip anyway
(for the touchpad). The benefit of using PS/2 is that we won't need to
write our own kernel driver - however, we will need to find a way to
reliably source PS2-UAB converter chips, or converter boards.
Post by r***@Safe-mail.netTo my knowledge you can use the
beaglebone black revision c to test i2c devices.
You can also use the Pi Zero for the same task, if I understand you correctly (just FYI).
Post by r***@Safe-mail.netI have this forestalled remark. I would prefer not to cut
in the asus eeepc's cabinet. If I do it wrongly, I do not have
another cabinet.
Hmm. That's tricky - I was planning to suggest the "cutting" approach, but
I don't know of a good way to cut into the cabinet so that it's easy and
mistake-proof. Thankfully, I have 2 spare cases to experiment with, and I
have some ideas =)
Post by r***@Safe-mail.netInstead at the bottom of the asus eeepc there is a removable
plate. There is a balk which likely can be removed. I would
prefer to insert the pc card by that plate.
I'll measure it and see if it's suitable - that is, if we can even insert
the card. I can't yet imagine how it would work, but I will think about it.
(the space inside the EEE case is quite limited, so there's only so many
ways to keep the card in).
Post by r***@Safe-mail.netI have not been able to find something like the pcmcia/eoma
68 breakout board. Should we not find a shop to buy
one?
I haven't yet found PCMCIA breakouts (or EOMA68 breakouts, for that
matter), so it's not a commodity item, and I'm guessing that places that
have them will have it at high prices, just because it's not that popular.
Lkcl has breakouts listed on Crowdsupply, but I imagine there's some time
until they will be manufactured and available. Until that, we can either
work on other tasks - and, later on, we can design our own breakouts if it
proves necessary.
Cheers!
Arsenijs
