I just setup DLG pro and I like it except it lacks certain features
I need.  Either I am unaware of how to configure it correctly or I
need utilities.  Could any kind DLG sysop please direct me to a source
of Utilities (in the USA, Please).  I FTP'ed over to wuarchive and they
had a small list of utils.  I Downloaded them all but there wasn't much
there.  Is there any other sources on the net that woould have more/better?
Namely I am looking for a util that will swap the name  <-> handle so I can
use fidonet.  I set it up so their handle is their name on my board, ie
%name = KnightRider and %alias = John Higgins.  Also I would like to locate
a working last 10 callers list for my login.batch and a top uploader/msg
poster util.  Also anything you may find useful I would be appreciative if
you could bring it to my attention.  Thanks to all responding DLG sysops
ahead of time!

A number of people up here in Saskatoon Can who are not sysops have

Hello Parnet users,
I do uses Parnet on two AMIGAs, A2000<->CDTV.
It works great and makes lots of fun.
But now I did buy a used SM-DOS computer to
get access to hd-disk drives ,(
(At our university in Saarbr"ucken, Germany,
there are SM-DOS comp's with hd's available for
any student to copy pd-stuff.)
But it is quite annoying to copy from hd to dd and then
bring the stuff to the AMIGA to read it using
multi-dos.
So it would be great if anybody could tell me if there
is a SM-DOS parnet version available and where to get it.
(Address, money, etc.)

Yours,

Yep, true.  But do you remember the beginning of the thread?  It was some geek

   Previous to v2.2 the font was fixed to an 8 x 8 matrix. This was very convenient
for multiplication and division operations which could use shift operations
instead of the `real thing'. With the introduction of user-selectable fonts for
user-interface and terminal window the shift operations were replaced by integer
multiplication and division operations. As for the MC680x0 version, these operations
would be handled by the compiler runtime library -- not necessarily the fastest
way to do it! The MC68030 (or rather: MC68020) version uses inline assembly
instructions, as supported by the CPU, which should be faster than the calls
to the compiler runtime library.

   I am afraid that both versions have (had) the same problems.

   A font may not be taller than 16 pixels, although this restriction will be
removed in a future release. Also, if you do not happen to run `term' under
Kickstart 3.0, you will be unable to use proportional-spaced fonts for the
user-interface.

>If so how do I unpack them?

Yes, both .dms AND .lha files need unpacking. For .lha files, you need a
copy of LhA, a rather neat little (un)archiver that also handles .lzh
files. For the .dms files, you need a copy of DMS. If you have bought any
Amiga mags with coverdisks in the past few months, you may already have
DMS and/or LhA. For example, the CU Amiga disk with Videoscape3D on it
contained DMS, as did the Amiga Format Chaos Engine/Legends of Valour disk.
Off the top of my head I can`t remember exactly where I got LhA from, but it
was definitely on a coverdisk, possibly an Amiga Computing one from a few
months back.

Note that .dms files are archives of COMPLETE disks, not files. Therefore
they require one blank disc to unpack to. .lha archives, on the other hand,
contain packed files, which can be unpacked onto any disc with enough free
space.

For both DMS and LhA, you can get on-screen instructions by typing DMS (or
LhA) without any options.

These are probably very trivial questions but
>I've only had an Amiga for a couple of months, so I haven't found much out

Hey, after a few months, nothing seems trivial on the Amiga. Just give it some
time and a lot of use, and you`ll soon get the hang of things. The Amiga
is not a computer to be used, it`s a computer to be experienced. Enjoy!

No and no.  Distribution of Workbench requires a softare license from
Commodore.  It is not free.  This is one of the reasons why many freely
distributable software packages simply do not contain the Workbench
executables.

Take your original master disks and re-install the software.  If you read the
documentation, you would have realized that you should only be working from
copies, not the originals, in your day-to-day work.

Assuming that your masters are also corrupted, you should be able to take your
master to a dealer and ask him/her to re-copy from a known good copy.  This
isn't legal either but is fairly common practise.

If you can't get to a dealer, look at the warranty cards that came with your
masters.  The address and price is quoted for replacing corrupted disks.  If
the disks are new enough, I believe that they will be replaced for free.  Of
course, if the disks aren't new, you should be able to recover from your own
masters since you did make your own backups, didn't you?

I have a friend who owns an A590 hard drive and has run out of the
meager 20meg of space and wants to replace the disk inside with a
larger one.  I have read that the A590 controller is quite good
if said disk is replaced.  I was under the impression that an IDE
style disk would fit in the A590 but a talk with a Best Buy salesman
got us the information that the drive in the 590 is of a type used in
the pre-286 IBM machines and is now VERY hard to locate. 

My question is this: Is there a source for the disk style that fits into
the A590, in a size greater than 20 meg?

e-mail would be greatly appreciated.

Also, in what way does it connect to the Amiga?  Does it use a Zorro II
slot, the parallel port, serial???  By the sounds of it, it isn't an
intelligent SCSI device, so that makes me wonder what the software is
like.  Will it run under Workbench 2.0?  Will it work with an '030?
Will it multi-task?  From what European software I've seen, these
last three are important questions.

All going well I could really use one of these.  Video tapes are so
cheap you could keep a number of backup copies, which you probably would
want to do for a device with no ability to verify.

to get into sound and video so I'm considering moving to either a Mac or an 
Amiga.  I'm not sure which model Amiga is best for graphics (do any of the
models have 24-bit color?) and video work.  What is currently available that
will surpass or at least equal my 386 in processing power (I would like to be
able to do full color raytracing and fractal generation, animate these images, 
combine them with sound and then transfer them to video).  Any advice on 
hardware and software availability would be appreciated.  Approximate costs
would also be helpful.  The Amiga is not widely available here so it is 
difficult to get answers here.  Does Commodore have an email address?

Please reply via email as I don't get much time to read the news.
