Can't get much cheaper than effectively free for a well regulated, high current DC power supply using a modified PC power supply that isn't otherwise being used. Plus, the idea of using tubes with 5V filaments instead of 6.3/12.6V reduces the competition with typical audio tube customers and makes the use of a high-current 5VDC supply possible. For the homebrew 1.5A adjustable DC supplies, I use LM317HV based units plugged into a homebrew chassis where I've mounted a range of three different inexpensive, surplus, multi-secondary transformers with output voltages ranging from 70VCT to 12.6VCT. The chassis has binding posts for each secondary and I just plug the banana plugs for the various inexpensive LM317HV adjustable DC supplies into whatever AC outputs most closely match the DC voltages I need at the time in order to reduce the power dissipation requirements of the LM317HVs.

Same deal - I gotta have SOMETHING set wrong... it still comes back to saying
that java isn't enabled.
Also, when I go to www.wagerline.com, the mouse-over drop-downs aren't visible,
as they are overlaid by the flash anim.
I used the adobe version - should I have selected on of the others instead?
And no, I'm not a gambler - I use it as a ref to see how my boys are getting judged
(Miami vs Florida).

Ubuntu looks pretty nice, even just the 'LiveCD' session i tried...
I booted up gOS beta 3, and it looks an awfuuuuul lot like Ubuntu...I assume there's some cross-breeding there
My WiFi worked on the Ubuntu LiveCD session, but does not under gOS LiveCD...
The old-school distros as nice as these out-of-box? Like Debian/Slackware/Suse/etc... ?
I'm starting an install of Ubuntu as we speak
Now, Jim, before I go digging, wasn't it you that mentioned some extra proggies for running games?
Was that to use std win games under *nix?

Thanks - downloading as I type this...
I figured as much last night, and downloaded/installed the JRE from java.com,
but it must've gone into the wrong place.
I shoulda' checked the package manager, I mean, it has a search function sitting right
THERE :)

Guys, I am having one issue, and haven't figured it out yet...
Trying to get the satellite images from the NOAA website at
http://www.goes.noaa.gov/HURRLOOPS/huvsloop.html
I keep getting errors about java not being enabled, and under Edit->Prefs,
I see both javascript and java enabled.
I'm using the Ubuntu-included FireFox, which is 3.0.1

I can tell you, so far, I am MORE than mildly impressed... little things like:
1) Batteries seem to last about 15-30 minutes more, depending on utilization.
2) In FireFox, entering "google.com" and pressing "enter" the page come up nearly instantaneous. IE takes 3-4 sec.
3) GUI looks pretty nice - what's with that flaming chicken? :) reminds me of HP's "verve" laptop paintjobs.
4) All hardware worked out of the box, but my speakers are messed up, so I can;t play with sound...
I need to dig a little more, and get into setting up the other requirements.

Hi!
A while back I mentioned the N8VEM SBC which is a new Z80 home brew project
designed in the "classic" late 1970's style. There was some discussion
about the merits of using RAM/ROM drives versus "real" drives like IDE hard
drives and floppy disk drives.
Work continues on the N8VEM project to include supporting "real" drives.
The SBC PCB and the ECB backplane PCB are basically done and available for
builders to make their own home brew Z80 CP/M computer. The next project is
an ECB bus monitor, which is basically done awaiting the PCB order, and the
next project is the Disk IO board.
I am currently working on the Disk IO board as my main activity. The Disk
IO board is comprised of two parts; an IDE interface and a FDC interface.
The IDE section is basically done, works just fine, and is supported in the
CBIOS. No doubt it could be improved with some TLC but it works well enough
for my purposes. Like the rest of the N8VEM project, it is comprised of
"standard" commonly available DIP parts with no custom or programmable
elements except for the SBC EPROM.
I am currently working on the FDC section and making some progress thanks to
some wise and very helpful persons (you know who you are!) The design
exists, is based on a NEC 765 reference design at the ALPACA project, and a
working but obviously still in development prototype board is on my bench.
As part of the development, I am writing a "disk monitor" program to
exercise the i8272 FDC chip. Currently, I can use it to read sectors from a
320K IBM PC MS-DOS formatted 5.25" floppy disk in a Tandon TM100-2A
minifloppy drive, print status, dump sector memory, etc.
If anyone would like to join in the development of the Disk IO board, please
contact me to discuss. I am making slow but steady progress but am sure
having another set of eyes to review and write code would help a lot. This
would be a great way to make your own Z80 CP/M home brew computer WITH
"real" drive support.

Thanks and have a nice day!
