BTW, in regards to MESS, the MESS team is looking for copies of the
various TRS-80 Model II bootroms. The different models of the system
cannot be emulated without them, and they're available approximately
nowhere that I could find.

I'd be happy to forward any documentation, boot roms, etc. to the MESS
team, if you're ok with that.

Actually they do cut trees in the National forests for the lumber industry. The Feds and State issue permits to the lumber companies to take a certain number of trees. Most of the trees they take in this area are mature hardwoods (Oak, Ash, etc..). I have seen the helecopters near my home lifting the logs out of the woods. It's expensive to remove them that way but, the environmental impact is lessened.
The revenue from the permits goes into a special account for underfunded or economically stressed local school programs. It has really helped the schools in this area (Western North Carolina). This particular program seems to be well managed and has the support of most of the locals.
This entire area was logged in the early 1900's so the trees they are removing today aren't really that old.

All:
I?m working on a 6502 project and I have a PC board CAD recommendation
question. I tried out the software that comes with ExpressPCB and it?s kind
of bogus. There?s no autorouter, which is exactly what I need (even if it?s
a basic router).
Does anyone have any recommendations for a reasonably priced schematics
capture and layout program for either Windows or Mac OSX that can autoroute
do boards up to say 6? x 8?? When I say reasonable, I?m thinking $250 or
less.
Thanks!

The old addage "When in Rome do as the Romans do" applies here. In a previous life I was a general contractor in South Florida. The vast majority of homes there are Masonary blocks on a concrete foundation with wood truss roof system. The reasons are simple:
1) Termites - Zillions of them! You gotta keep wood away from the soil. Subterrainian termites can do massive damage in a relatively short period of time.
2.) Maintenence - Environmental exposure (Sun / Heat / Humidity) destroys wood.
3.) Insulation... In that climate large R values are not needed in walls or floors.
4.) No basements - Water level is too high. No basement means there's no need for wood flooring systems.
5.) Material availability. The ground in South Florida is largely limestone. It's one of the primary ingredents in concrete and it's easily crushed to make the aggregate (gravel). Concrete is probably cheaper there than anywhere else in the US.
6.) Hurricane protection - A concrete block structure with reinforced concrete tie-beam is MUCH stronger than a wood structure.
7.) Availablity of tradesmen familiar with the materials.
I recently moved to North Carolina where almost every home is wood frame construction. Once again "When in Rome..."
Apparently, G L sells items that in fact weren't supposed to be sold,
forcing the buyers to return them!
It only reimburses you for the cost of the item, not the shipping.
Be VERY careful about what you buy through them!
Read the fine print on the government as well as GL sales site agreement.
This is the second incident like this I've heard about in the past week.

To Whom It May Concern:
In Sale xxxx you were the successful bidder for Lot xxxx, Invoice number xxxxxx. Since the close of that
sale we have been notified by the Government that the demilitarization code for a DTID in this lot, has
changed to DEMIL ?D?, thus we?d like to inform you of the action required by you.
Description: DATA PROCESSING SET
Quantity: 1
NSN: 5862xxxxxx4434
DTID: SC44xxxxxx00VD
Because demilitarization code ?C? items require total destruction of the item and components so as to preclude
restoration or repair to a usable condition, we would like to make arrangements for you to return the above
DTID to the nearest Government Liquidation site. If you still have this item please contact Government
Liquidation within 19 working days to coordinate the return of this property. Once the property is returned
to a Site Manager with a copy of this letter, and the site manager signs and provides a copy to your
representative showing he/she has received the DTID a credit invoice will be created.

Osmond runs on OSX (and earlier Mac OS) and I've found it to be very
usable. I have not used the latest version so I can not comment on
the quality of the auto-router. However, you can try it for free.
If your design's pin (meaning inflection point of traces, I believe)
count is below a certain number, you can use it for free.
Regardless of your design's pin count, you can lay it out and route
it, but if your design reaches into the paying region, you won't be
able to output it. Still, that will let you try out the
auto-router without investing any money. If you do want to purchase
it, I think (IIRC) it is in the $200 region.

I've used it for a few board designs so far which I've output as
Gerber for manufacture and it has worked well.

Hi
This is all getting a bit complex. Its rather like a peculiar type
of English theatrical entertainment which happens around Christmas
called a Pantomime. One of the many strange customs is that under
direction from the stage one half of the audience shouts "Oh no it
isn't!!" and the other half replies "Oh yes it is!!" Don't ask me to
explain it any further. The rules of cricket and the plots in Chinese
opera are simpler.
So back to the original question:
If I want to build a Linux system I go to a distribution site (one of
many), download an .iso image, burn it into a standard 600Mb CD, boot
the CD and create a system. No funny block sizes, no odd file extensions
and no special SCSI drives. So what can I not do this for VMS without
the pantomime? A step by step known to work checklist would be a start.

Strictly speaking, yes... but extension rigidity is a Windows mentality.

Ah... I had thought that the underlying filesystem was part of the
equation, not that the drive did all the work.

I have worked with plenty of "starts up in 512-byte-block mode" issues
with old SCSI drives and Solaris - it does make boot code trivial
because you don't have to worry about the drive's block size. It was
nice with later versions of boot ROMs and such that knew that they could
and should send a packet to tell the drive to switch to 512-byte-block
mode, removing the need for special models of drives with mode jumpers.
Honestly, though, I haven't had to worry about it (except when playing
Software Archaeologist) in a long time, but then I don't burn ODS disks
often.
