Re: [Soekris] net6501: are the E6xx LVDS pins available as pads anywhere?

Thank you for that link.  I have been looking for "terminal emulators" and I have found the PockeTerm http://www.brielcomputers.com/wordpress/?cat=6, the Spare Time Gizmos VT6 http://www.sparetimegizmos.com/Hardware/VT.htm and the $360 (ouch!) NTI SERIMUX Terminal Converter http://www.kvms.com/Product/SERIMUX-TERM.aspx.

The MicroVGA seems like the lowest cost solution, I just need to add a bit of perf board, a header, a MAX231CPD and two (tantalum) caps.  As a benefit, there's a spare pair of drivers for the second serial port.

Soren, I understand why the E6xx integrated video is not useful because of the supervisory LPC processor, and you would have to implement a video BIOS.  Have you considered using the supervisor MCU as the terminal emulator to generate the VGA video?  It could pass through the serial data and only inject characters if a PS2 keyboard were used.  Looking at the MicroVGA, we've come a long way from Don Lancaster's TV Typewriter (I still have the "Cookbook," dog eared, packed away in a box some where).

Thanks again,

Andrew

Hi, I've been looking into upgrading my aging firewall from a pentium-m 
running FBSD 4+ to something more recent.

Since I've stumbled over the net6501, I have tried researching it as 
much as possible.  My firewall is also my GPS strat-1 NTP server, UPS 
monitor and DHCP server, among other services.  Because I use a KVM to 
switch VGA between servers, I am looking at a simple VGA solution for 
the net6501.

Thanks-

If you only need VGA, mouse  and KB to manage your system within a text
console using a KVM, I suggest you take a look at http://www.microvga.com/
They produce a small and cheap (VGA + 2x PS/2 connectors) <-> (RS232)
conversion module that could solve one of your problem.
