Huge differce. also the Floppy controller is on the MB for most current

Trivial problem. the cables have both. The real problem is when the
software goes to work or out to lunch.

Well, let's see. I use a Radio Shack model 100 (like many people) for
taking notes/writing away from home. Once I get my Starlet fixed, I'll be
doing the same with that (CP/M laptop, with Wordstar in ROM). I also have
an Outbound notebook (mac clone laptop ca. 1990) that I and my girlfriend
use.
She (Rachel Grilley, <auntierae(a)california.com>) also uses older macs in
her classroom to teach her first graders reading, math, science, etc. They
range from plusses to IIci's.
My voicemail system is currently running on a 286/512K/40mb system, but is
about to be upgraded Real Soon Now to a shoebox-sized 386sx system I picked
up recently at a surplus place. (Same VM card/software, just different
computer -- actually can run on an 8088 even.)
I have an Atari Portfolio (8088, DOS, size of a video tape) that I carry
around for taking notes.
I also use my Atari ST's and Falcons for music sequencing/recording.
(Well, not as much as I like, but once I win the lottery...) I can also
put you in touch with a lot of people who are using their ST's a lot.
And lastly, my main machine is a 486 laptop, but I have written a DOS-based
application to manage the San Francisco Free List (see
<http://www.sinasohn.com/freelist/> for more info) including maintaining
the database of events, building daily and monthly web pages, and
generating weekly event listings. Eventually, I'll probably move that onto
a different DOS-based laptop so others can assist in maintaining the events
database.
Anyway, feel free to drop me a note about any of the above (or anyhthing
else, for that matter).

It's not quite the same. All PC components are third-party and thus
there is no guarantee it will work quite right. Are the
well-documented IBM PC, XT, and AT machines better in this sense?

Why do you need an 8" controller? The same floppy controller can be
used for both 5.25" and 3.5". There never were any jumpers for any
MFM drives, nor have I seen much for IDE drives. This has nothing to
do with PCI or PnP. Just set the correct type in the BIOS and that's it

In fact, I am not familiar with any real difference between PCI and
ISA controllers. I have never had any floppy problems. The reason
why I said 'if you can plug one in' is because the 5.25" drives use
edge connectors, unlike 3.5" which use BERG strips (is that what
they're called?). This is the biggest problem one is likely to have.

I almost forgot to post about this. I recently acquired a complete
Heathkit H89 system, with dual floppies and a small printer (OkiData
Microline 82, serial), all in excellent condition.
I got with it a bunch of manuals and floppies, among them CP/M boot
diskettes. As I recall, this is a Z80-based system, yes? Is it possible to
use a hard drive on it?
Thanks in advance.

Apple ][ disks don't use standard FM or MFM encoding, so Macs and PCs can't
read them. If you can find a serial car for the Apple, the easiest way
would be to get a copy of Kermit-65 (for DOS 3.3 files) and/or Kermit80
(for CP/M) and transfer the files over a serial link -- that's what I do.
Kermit-65 comes with instructions on how to get it into an Apple that
doesn't already have any kind of file transfer software, and IIRC Kermit80
has some similar instructions. You can get Kermit by anonymous ftp from
ftp.columbia.edu, or http://www.columbia.edu/kermit/, or from any of
several mirror sites.

Several months ago, I was given an A][+, with a z80 card and a bunch
of program, as well as data, disks. It has a printer interface card.
What is the easiest way to transfer the data on these disks (CP/M 3.3
various programs, mainly Wordstar 2.x) onto a PC or mac? Is there a
PC program that will read Apple CP/M disks? I couldn't easily do it
with a Mac since these are 5.25" disks.
