This takes me back quite a while, so I'm no 100 percent sure....

Radio Shack used to allow 4 drives on the COCO controller. The way they did
|
|
this was:
|
|
|
|
a) address all drives the same INTERNALLY, and then pull pins in
|
|
the cable connectors at each drive to decide which drive address
|
|
bits could be passed through to the drive. As a result, the drive
|
|
number/ID was a result of WHICH plug you had used on the RS drive
|
|
cable (normal disk setups used all pins at each plug, and the drive
|
|
ID jumpers were set on the drive's internal configuration block.)
|
|
|
|
b) Radio Shack used the SIDE SELECT line (side 0 or side 1 - used for
|
|
selecting which head to use in a double sided drive) as a DRIVE 4
|
|
address line. This is because they never offered DS drives for
|
|
the coco, and it was a cheat that allowed them to use a 4th drive).
|
|
|
|
|
|
So the first step you must take is a) Get true 40 track DS drives, then b)
|
|
Address them properly, and c) Get a normal 34 pin drive cable (you could just
|
|
add plugs to your existing cable). NOTE: don't use an IBM PC floppy cable...
|
|
they twist the address lines around in those.

Thx for the reply. If that's what it takes, I don't believe I'll make the

Sb: #Disk Junked?
|
|
Fm: David Breeding 72330,2051
|
|
To: all
|
|
|
|
I just had a file on my HD junked and can't figure out just what's going on.
|
|
|
|
Last night, I had zipped a bunch of files into one huge one to put onto a PC
|
|
disk for a friend. In the process, I got it too big for the disk and had to
|
|
"zip -d ..." a few. I then copied the one file to the PC disk.
|
|
|
|
I cannot remember exactly what all I did last night.. I later came on here with
|
|
"ix". I also may have used an experimental telecom program, too, but don't
|
|
think any of this caused it.
|
|
|
|
Anyway, today, apparently the FD pointer for that file was pointing to a
|
|
section (or all) of the file CompuServe.usg, written by "ix". Dcheck showed
|
|
"Bad FD Segment" for stuff in the zip file, and showed that ".usg" was using a
|
|
a sector already allocated.
|
|
|
|
I could not find the true FD for that file.. I finally located a previously zip
|
|
file and repointed my FD to that one, but of course none of the sectors were
|
|
allocated in the bitmap. I couldn't delete, deldir or attr -nd that file till
|
|
I did that. (got error 244). (Oh, somehow, I did get a glitched directory
|
|
entry last night, too, but was able to del that file.
|
|
|
|
I finally just "del"ed that file with the bitmap not set, was not sure what
|
|
would happen, but dcheck reported everything OK after that.
|
|
|
|
I'm just wondering what happened? I can't remember, but apparently, after
|
|
copying the file, I must have deleted it, or the sectors used by the file would
|
|
have been still allocated, right? If this is the case, then somehow when I did
|
|
the "del" (if I did), the bitmap was reset but the entry in the directory was
|
|
not killed off. Could it have been some combination of the programs I was
|
|
using? Perhaps somehow the PC driver left a PC-type setup in the system and
|
|
when I did del, without doing a specific full path, it got confused? Could
|
|
"zip" have done something? But the file _did_ copy to the PC disk correctly,
|
|
so dunno... it's a real mystery.

When this happens it is usually a good idea to make sure that everything on the
|
|
HD is backed up, reformat it, and restore all the data. Could be that you have
|
|
a sector acting up.
|
|
|
|
If you just have one file which you can't read (due to a bad sector, etc) it is
|
|
easy to lock out the entire file (including the bad sector) by using DED to set
|
|
the first character in the filename in the directory to '0'. That way the file
|
|
disappears, but the storage remains allocated...at least that way nothing else
|
|
can use it.

|

|
|
around with it today trying to get it to happen on my floppy. Oh, it happened
|
|
again last night. (Make that Sunday, might not u/l this on Mon, when I'm
|
|
composing).. I had gone online abt. 10 PM. Had composed a QWK reply, taking up
|
|
two 512-byte sectors + 1 for File Descr. About 11PM began doing some more
|
|
zipping.. I was zipping severaly files, ranging from 40K - 600K (before
|
|
compression). I wound up getting about 1.75 meg in file.. I did "zip -d" for a
|
|
few to get it down to fit in 1.44M floppy. I _think_ a time or two, I had run
|
|
dcheck, can't remember exactly what I'd done.. Then I copied the file to a PC
|
|
disk. I then del'ed the zip file. Then I did dcheck had 3 sectors "not in
|
|
bitmap" - traced them to be the QWK reply. I just "del'ed" that file and
|
|
everything was OK.
|
|
|
|
I don't think I had run dcheck immediately before copying to PC disk, but I'm
|
|
sure I had done it at times during the zipping, after my previous observations.
|
|
I suspect that somewhere along the way, "zip" walked right over the little
|
|
file, probably occupying a sector immediately below that file and then just
|
|
going right across it. I'm beginning to suspect that the trouble might be in
|
|
zip with large files. It writes temp files and it _could_ be it cheats or
|
|
something, possibly rewriting to the disk directory structure, but this is just
|
|
a guess.
|
|
|
|
I tried to duplicate the error staying strictly in the floppy, writing small
|
|
files and having plenty of fragmentation... Finally did get an error with
|
|
beaucoup "not in bitmap". The only thing is that with my system, our floppies
|
|
are dreadfully slow.. Actually, when this error had occurred, I had rewritten a
|
|
device descriptor (/f0) and changed the step rate to 3 (6ms) hoping to get it
|
|
faster, so this could have been the prob.

|
|
|
|
So far, I've not had unreadable files as such, it's the bitmap that's getting
|
|
munged, I think mostly from files writing to the same sector. (The FD gets set
|
|
correctly, apparently, but the bitmap is not being followed correctly.
|
|
|
|
I feel it is either one of my programs (either zip or my PC disk driver) or my
|
|
system is writing to the disk when it is not positioned correctly.

Is there a way to install an interrupt handler without using device

a Motorola MV162 board. A short example would be extremely helpful.

I tried the _os9_irq call but it gave me a runtime error (Errno = 208)

|
|
You must be in system state to install an interrupt service routine, but
|
|
you don't have to do it inside of a driver. You have several options:
|
|
|
|
- write a dummy driver which just installs an interrupt service
|
|
routine in the INIT routine and deinstalls it in the TERM routine.
|
|
|
|
- write a system state application that uses _os9_irq to install
|
|
the interrupt service routine.
|
|
|
|
- write a system state trap handler which can be called from a user
|
|
state program. The trap handler can install the interrupt service
|
|
routine.
|
|
|
|
I usually opt for the middle suggestion: a system state application.
|
|
|
|
If you write your interrupt service routine in C, you'll have to write
|
|
some glue code in 68K assembly to move contents of registers around.
|
|
|
|
I don't have any example code on my system, but you need to tell C
|
|
compiler that your program is a system state program:
|
|
|
|
/* I'm assuming you're using Ultra C because of your _os9_ call */
|
|
_asm("_sysattr: equ $A000");
|
|
|
|
You then need to write a small assembly language routine which moves
|
|
registers and does a bsr to your actual C interrupt service routine.
|
|
|
|
Be aware that paths are subtly different in system state vs. user state.
|
|
|
|
Again, sorry. I'm typing all of this from memory, and don't have example
|
|
code in front of me. Feel free to pass any other questions along.

Hello,
|
|
I have a Tandy 2500SX computer that is a number of years old. It came
|
|
loaded with Dos 5.0, and 1MB Ram on the motherboard. All worked well. I
|
|
upgraded to Dos ver 6.2. All still worked well. I then added 4MB of Ram to give
|
|
it more power. When I rebooted the computer after I installed the added memory
|
|
I got a message that I needed to run the startup program to reset. That program
|
|
is StartupSX.exe that came on the original Dos 5.0 program disks that came with
|
|
the computer. It is sopose to read the computer configuration and reset the
|
|
bios (I think). However, When I run that program, and restart the computer I
|
|
still get the message that there is a difference and I need to run the setup
|
|
program. Could setupSX.exe be incompatible with Dos 6.2?? Any ideas on how I
|
|
can get my computer to reset to the new configuration?
|
|
|
|
Thank you,

1) I doubt that setupSX is DOS dependent... It probably asseses the config and
|
|
writes it to CMOS. Just to be safe though, try booting DOS 5.0 from a floppy
|
|
and then run the program.
|
|
|
|
2) You'll probably have more luck in one of the Tandy forums... This is the OS9
|
|
operating system forum, and while a number of Tandy users are here, most of
|
|
them don't run DOS compatible machines.
