My favorite tool is Warren Toomey's "apl2serial", available by anonymous

There are also numerous other tools available on any of the gigabytes-of-

I picked up an AppleII CP/M card and software yesterday and causes me to
raise a question...
I have a ton of old 5.25" discs from TRS-80's, Apples and etc. Can I use a
IBM Compatible and a disc image program (like scopy) to archive these
discs? If not, how can I archive these programs?
Thanks

Consider: will the packaging degrade over time in a way that affects
the artifact? Shipping cartons aren't really intended for long-term
storage, they're intended to protect the contents during shipment
which hopefully won't take 20 years. Styrofoam and plastics can melt
if they get too hot (i.e. styrofoam peanuts and plastic bubble wrap
tend to have lower melting points than do computer cases and cords,
and those temperatures can easily be reached in shelters that are
exposed to sunlight like outdoor sheds), and rubbers and glues can dry
out and/or turn gooey over time.

The Coleco "Adam" was one of the first mass-marketed "home" computers which was sold as a complete unit, i.e. it had a printer and storage device (originally a tape drive of some odd sort), and coming from a relatively popular game maker didn't hurt either. The basic unit IIRC cost very little and, I'm not sure of this, but I do recall a price of <$500 for the entire mess. The price was quite low, so it was quite frequently purchased. People unwilling to admit they couldn't get it to do anything useful simply threw them out and bought a Kaypro or something similar.
I saw many of these make the trip from the store to the dumpster in less than a month, though, since they only "sorta" worked. The challenge here was to make them do something useful, which was quite a feat, I guess.

Subject: Why is the Coleco Adam so popular?
Sorry for the previous post, it got away from me before I was finished :-(
This might be a bit off of at least the current topics, but probably the best place to ask this question.
I have to admit I bought one of the Coleco Adam computers in the summer of 1984 (The Adam bomb). I soon found that it really didn't work and like most I returned it to Toys-R-Us for a refund.
I bought a KayPro 2X then and was very happy with it. I used the KayPro up until 1993.
Recently I searched for information on the Kaypro on the Web and other than some pictures of the old machines I really found very little about the KayPro computers or company.
But then tonight I noticed a link to a Web site on the darn Coleco Adam and I found that there are still many devotees of the little system, many Web pages, and even complete systems for sell!! These people are still having conventions!! I would think it would be the other way around. It seems as the Kaypro should still have it's UG's and Web sites and the almost worthless Adam would be long forgotten.
Can somebody tell me why the Adam has enjoyed so much loyalty from people 14 years after the two year poduction run ended in bankruptcy?
I really am mystified by this.

The model 12 was no great thing . . . Unopened and in unused condition,
however, it might bring a fair price on eBay. That's what I'd do if I had
to deal with this.

I've seen lots of floppies with this problem. I find that it occurs on
systems which (a) leave the motor on and the head loaded (not an option on
low-cost 5-1/4" drives, the head was always loaded) and (2) drives with some
form of contamination, i.e. particulates, on either the head or the
head-load pad. Dust and smoke are often the offending contaminant, i.e.
they damage the extremely hard surface of the head, normally polished to a
very fine finish, and leave a burr which subsequently scratches the emulsion
off the media. In any case, the problem is much scarcer in "clean"
environments than in my basement or anyplace like it.
Solution: (a) take the media out of the drive when it's not in use and (b)
make the fan in whatever enclosure houses the drive blow into rather than
suck out of the enclosure, preferably through a filter of some sort.

Well, I am not real knowledgeable about computers but I have still an old Toshiba 1000 that I bought for $150 in 1993 at a hamfest. I used it for packet radio for awhile. It had a 3 1/2 " internal drive and I bought a 5 1/4" external that came with a big brick power supply for $50 dollars for it.
I think the Toshiba 1100 was really about the same thing.
When I was looking for a 5 1/4" drive in 1993, I remember people telling me that MicroSolutions made one for various notebook computers. I think I have the name of the company correct. MicroSolutions also made external hard drives and tape drives they called/call the back-pack I think.
My Toshiba works,err, maybe worked, with its own connections. I think the MicroSolution stuff was all parallel port.
I have always wondered if somebody has written a driver for my parallel port 100 Mb Zip drive to work with the old XT type Toshiba 1000? That might be an interesting solution for you also.

There are probably several ways. Here's a few I've used:
1) use the 'w' option to tar; it will prompt you for each file/dir to be
included. Could be tedious, though.
2) use GNU tar, which has an option to read a list of files/dirs to be
excluded, from a file. There's a similar option to read the list as part
of the command line. I can't remember the options (and this system doesn't
have GNU tar so I can't look them up) but I do remember you have to make
the pathnames in the file to be *exactly* as tar will see them.
3) use find (or your perl program) to create a list of files to be
archived, excluding all directory/subdirectory names; then it won't recurse
into subdirectories. Eg:
find . -type p <rest of expression> -print | tar cf tarfile.tar -
The '-type p' makes find only print names of plain files, not directories
or special files, etc. Problem is that you will end up with a flat file in
which you can't distinguish which directory files came from from.

This made me remember that I have a perhaps similar problem with one of my Kaypro drives. It works at first, but eventually wears away portions of the disk making the disk unusable. (After a few uses, if you hold the disk up to the light there are arcs that are clear.) I assume this is a head alignment issue. If so, is there an easy way to realign the heads (perhaps dropping the unit a la Apple III), or should I just look for another floppy drive?
Forget tar. Use pax. Put the names of the
files you want to backup in a file, feed it in.
# collect the files
&cmd("pax -w -f $backupname.pax < $backupname.paxin");
# make a listing
$ENV{"LC_TIME"} = "%b %e %T %Y";
&cmd("pax -v -f $backupname.pax > $backupname.paxlist");
# compress
&cmd("gzip $backupname.pax");
