[gentoo-user] slightly OT, laptop for gentoo

[Mike Williams]

Hey all,

I need a laptop. But the requirements are slightly odd.
This is for a machine to stay in our colo cage for use as a barcode scanner, 
serial interface, basic GUI, and ssh server management console, etc.
It needs to have USB for an eToken, PS2 for a barcode scanner, serial to 
manage PDUs KVM etc, on-board ethernet, and not be flimsy, big, or expensive.

Obviously we can easily get a USB to serial adapter, meaning we'd need at 
least 2 USB ports, but a PS2 keyboard port seems a rarity now-a-days.

Battery life isn't really important. Doesn't need to be a properly ruggadized, 
just sturdy. 15" or so screen, with a decent resolution to fit webpages and 
OO documents etc, 17" is too big. 512-1G of ram, so-so CPU (this P4M 1.8 I'm 
using is way more than powerful enough).

Can anyone recommend a laptop that does all these things, runs Linux happily 
(Gentoo of course), and isn't a Thinkpad (I was forced to use one a few years 
ago, and hated it).

Thanks

Have you thought about a PS/2 to USB adapter?  I'm presently using a
PS/2 keyboard _and_ a PS/2 mouse connected to a single USB port (with a
"Y" adapter -- dual PS/2 inputs and USB output).

Also a USB hub might work to connect multiple USB devices to a single
port.

HTH,

David

D'you know what, I didn't even realise such a thing existed!
I've probably got dozens of USB to PS2 adaptors, and never imagined the 
opposite.
A dual PS2 to USB could well do the trick, and my local Maplin have some in 
stock, a bit pricey but the company will pay.

Thanks very much.

Here in Michigan they seem a bit pricey, as well.  A single PS/2 to USB
adapter is a few dollars but the dual PS/2 to USB "Y" adapter is $16.00
(or worse).  I had hoped to use one with my PS/2 only KVM but the combo
doesn't work.  I suspect the issue is with the KVM as I have 2
different "Y" adapters and neither works.  Sigh :-<

The Dell business models (precision) docking stations have 2 PS2 ports.

A docking station would be an excellent idea if you need the peripherals
to work without fussing with cables.  If/when you do need to pick it up
to move / replace something, you don't need to worry about unplugging &
replugging 6 different cables in the right spots...  You can even tie /
screw the docking station down (or get one of those D-View laptop
stands)

sorry about the ebay links, but dell of course doesn't list these things
in their "products" page...

If you buy a docking station, double check what kind of AC-adapter you
use. A PA-12 (65W) is not powerful enough to supply a docking station.
You'll need a PA-10. Some notebooks are shipped with a PA-10, some with
a PA-12 with no apparent system.

Here are these cables for only $5 delivered (worldwide):
   http://ledshoppe.com/Product/com/CA4036.htm

I have used Ye Olde Ledde Shoppe on a number of occasions and have  
been very happy with their service. A delivery failed to arrive once  
& I contacted CCnow (the payments processor) and the purchase price  
was refunded immediately; a replacement order I made with Ledde  
Shoppe arrived a few days later.

These Y-cables are supposed to work with KVMs, but I have only had my  
KVM a couple of weeks, so haven't gotten around yet to testing  
thoroughly. My KVM is (apparently) PS2 only, but it does have a PS2 /  
USB keyboard setting in the configuration menus, so it might be worth  
playing with that if yours is the same.

Stroller.

I'm willing to gamble $5 on a company I've never heard of.  If it works
with my KVM it'll be great (and I'll be able to return the $16 cable
that doesn't work).  Even if it just works with my keyboard and mouse
I'll be able to return the cable.  How can I lose???

You can still get laptops with real serial ports (HP sell them). You
might want to investigate whether you can manipulate the USB serial
adapter to your requirements. I tried once with setserial and it didn't
work - I havent had time to look into it further (potentially driver
dependent??). Minicom works fine for configuring routers/unix boxes
however.
