[plug] Linux Mobile project

[Leon Brooks]

Tony B-T got to see it first, now it's resurrected (and I'm working
through it as a dialout gateway ta the moment) and working happily again
- the Linux Mobile project!

It's a 486-SLC-40 with 12MB of RAM and a 250MB hard disk, suspended with
string from some sections of skirting board to make a beautiful if
somewhat scarey mobile, with flashing lights and all! The SLC means
"without maths coprocessor", so I had to build the hard disk on my K6-II
machine, then recompile the kernel for a 486+mathemu. I had to delete
the kernel sources to make enough room for installing Apache etc. The
12MB of RAM comes as 4 1Mx8 30-pin SIMMs plus 1 2Mx32 72-pin SIMM.

The hardware is so slow that I cannot run the modem interface at 115200
or it loses characters. It took nearly a minute to generate the 768-bit
key for the ssh daemon on install. Yet scripted, database-backed web
service is still quick (although noticeably slower on the old 250MB
Samsung hard disk than the newer 850MB Seagate that it started with
(which suffered deceleration trauma about an hour before the PCUG
presentation)).

Attached is the dmesg listing with BogoMIPS, IDE drive messages et al,
for those who enjoy such things, and a "top" snapshot. Note that this is
running scipted web service, an SQL database, name service,
(Open)SecureShell daemon, masquerading/firewall and the PPP link.

Now, the important part of this post: I need to borrow a digital camera
to take some piccies of it. Do you have one that I can use?
