 Subject: MacPlus bug(?), observations

 The NCR 5380 IRQ line is not connected.  The VIA 60hz interrupt code
 you found is superfluous at best and harmful at worst: if a
 powered-off SCSI device is attached, the IRQ bit will always be set,
 causing the rest of the VIA interrupt handler to always be skipped,
 making the Mac useless.  This bug is fixed in currently shipping
 versions of the ROM. The first branch in the VIA 60hz interrupt
 handler is now unconditional to skip over the offending code fragment.

 Subject: PX and SC in Maxbug?

 The Macsbug PX command toggles the display of procedure names on disassembled
 code.  For it to be useful, the names must be embedded in the code per the
-Lisa
 Pascal D+ option convention.  That is, an 8-character string (no length byte),
 blank-padded, must follow the RTS or JMP (A0) at the end of the routine, which
 in turn must follow by not too long a distance an UNLK A6.

 Maybe not particularly "easy," but...  post an application event, then
 (with interrupts disabled) find the event in the queue and modify it
 to whatever you want it to be.  Reason for making it an application
 event is to make it easy to find in the queue, since you'll be the
 only source of such an event, while there could be more than one
 keydown in the queue.

 Subject: HFS Backup 1.1
 Date: 9-JUN-18:12: Bugs & Features

 Well, I did it ... got my copy of HFS Backup from PCPC (MacBottom) and I like
 it, but found an interesting bug ...

 The program really needs a '400K disk only!' option.  I was in the
 middle of backing up, and I got a format error caused by an obvious
 misinsertion of the disk (it made the squeaky noises).  Ordinarily if
 that happened, you'd get the Eject or Initialize box on inserting the
 disk, and you'd eject it and try again.  However, since it was
 formatting automatically, it went through the format process and gave
 me an error dialog again.

 So I reinserted the disk!  WRONG!!

 It formatted just fine this time, but as an 800K disk!  The tipoff is that it
 didn't ask me if I wanted to inititalize it or not.  However, I might not have
 noticed that if I had been distracted!

 One other (rather minor) complaint I have is that it shows you the
 number of the disk you are going to format next at the time it spits
 out the disk you are now about to put the number on.  I keep
 forgetting to subtract 1 from the number.  (Of course I could label
 the disk before I put it in to be init'd, but what if it doesn't
 init?)

 More interesting things about HFS Backup ...

 If you select the option to always format the disk, it makes 800K disks if it
 can.  Once again, there really should be some way of keeping it from doing
-this
 if you are using single-sided media.

 But, more interesting is the fact that there doesn't seem to be anyway to make
 it write an MFS 400K disk.  I even tried unchecking the box for verifying the
 disk before backing up and feeding it an MFS disk, but it still turned it into
 an HFS disk.

 There are two problems with that ... one is that an HFS 400K disk is
 several K smaller than an MFS 400K disk, and the otehr is that I would
 really like to be able to read the backup diskettes on a non-HFS file
 system, even if the files have been saved in a peculiar format, since
 I would have a chance of recovering a file that for whatever reason
 might not be restorable.  (I don't know yet whether the restore
 function needs to be able to read the backup directory on disk #1 of
 the backup series in order to be able to selectively restore a file).
 This would only be a concern in the event of a major disaster such as
 loosing both my Mac Plus and my 512K Mac, so maybe it's not a very
 serious problem.  I'm just grumbling a bit.

 Otehr than that, the program seems to be working very well.

 I'll reformat and restore my HD-20 later tonight.  Film at 11.

 Date: 10-JUN 00:02 Bugs & Features

 OK, I reformatted my HD-20, and ran HFS Backup to restore the files.  All went
 well except for one tiny thing which you should know about before you try this
 yourself!

 That is to say, at the end of the restore I rebooted from the hard
 disk (I had been running from a floppy disk system), and nothing
 happened.  I tried reblessing the System Folder, and that didn't fix
 it.  In retrospect, the answer is obvious ... nothing in the Boot
 Blocks, but I was mighty puzzled for a few minutes.  Copying System
 and Finder from the floppy to the HD-20 fixed it.

 Now that I've done this once, I can recommend an alternate procedure, which is
 to set up your essential files like System and Finder before the restore.  It
 seems the program will ask if whether to restore a file or not if it already
 exists (it did this with the Desktop file, and I replied NO).  That way you
-can
 control the placement of the System if you want.  (I have visions of putting
 System and Finder in the middle of the disk by clever reservation of file
 space).

 Also, you have to rearrange all your folders, since their positions get lost
 when you fail to copy the Desktop file.  Perhaps next time I'll try restoring
 the Desktop file too.

 Hmmm ... the more I look at my restored system, the more I realize that
 restoring the Desktop was probably important ... no document icons!

 So I rebuilt the desktop by holding option-cmd down as soon as the billboard
 appeared and until the Finder asked me if I wanted to rebuild.

 Much better.

 Reformatting destroyed the boot blocks; HFS Backup does not back up or
 restore them.  Normally (sans Fedit) boot blocks are copied by Finder
 from the source to the destination disk whenever the System file is
 copied.  BTW, Finder doesn't care what's in those boot blocks, it just
 copies them.  If you had copied System FROM your HD20 with zeroed boot
 blocks TO a diskette, you would have rendered the diskette unbootable.

 If you restore everything, including DeskTop, all your folders and
 icon positions and views will be as they were.  I just use Fedit to
 recreate the boot blocks.

 Date: 10-JUN 15:34 Bugs & Features

 The last thing I did yesterday with HFS Backup was to experiment with the
 incremental backup feature.  First I ran it under normal circumstances to see
 that it works.  It does.

 However it also writes on the first floppy of the disk set, updating
 the backup directory (it also copies it to the last disk of the set,
 in case you have problems).  Since I saw that there was very little
 space left on the first disk, it occurred to me that there might not
 be enough room to update the directory if you had accumulated a lot of
 changes since the last backup.

 So, having started with 800 files on my disk, I created 600 new files,
 each 1K in size, and ran the incremental backup.  After much chugging
 and whirring, the backup finished (having written 5 disks to add to my
 set of 49 from the full backup).  It worked just fine, and the backup
 directory was still the same size!  Evidently it is the same size no
 matter how many files there are on the disk, so there must be a limit
 beyond which you cannot proceed.

 Since I still had about 600K left on my disk, I duplicated the folder
 containing the 600 1K files, giving me a grand total of 2000 files on
 the disk, and told HFS Backup to do a full disk backup.  After reading
 the directory for a while, it gave me a dialog box saying "Backup
 directory is full, file "xxx" will not be saved. OK" ... I clicked OK,
 and it immediately went into the sort of the directory ... and stayed
 there.

 After 20 minutes I concluded that it wasn't ever going to finish, but I left
-it
 running overnight just in case.  When I woke up this morning it was still
 looping.

 Some additional experimentation reveals that the directory gets filled up
 somewhere aound 1500 files (in my case, see below), and if it gets full, the
 sort loops forever.  Thus you cannot do a full backup when you have too many
 files.  Nor can you do a selective backup, since it tries to process the full
 directory anyway before giving the option of selecting anything.

 Your only recourse would be to unload files by hand to make the directory
 smaller, or use Harry Chesley's PackIt program to group a bunch of small files
 together to save space in the directory (and on the disk too).

 I mentioned above a limit of 1500 ... I imagine that this depends on
 whether you like to use small file names or large ones, though I don't
 know for sure.

 I feel reasonably comfortable with this personally, since I only have
 800 files and probably won't have a much larger number under ordinary
 circumstances, but the situation is quite different for someone
 running a really big disk on the Mac, such as an AST 74 meg disk.  A
 disk that size would easily hold 3000-5000 files, and is still within
 the realm of reason for floppy disk backup (100 double-sided diskettes
 for the full backup, and then stick with incremental backups).  I
 suspect that the HFS Backup program is really designed for 10 and 20
 meg drives though.

 Gee, Rick should've gotten you to help with the review!

 Were you using an 800K disk as Backup #1?  Does that make any difference in
-the
 size of the backup directory?  Does the backup directory get sized at creation
 time based on the HFS directory size?

 Something to note with the extra copies of the backup directory is that you
-are
 actually saving different versions of the backup directory each time you do an
 incremental backup and it writes a copy to the incremental backup disk. The
 Backup #1 disk always reflects the latest status of the whole set.  The copies
 don't.  (That's my interpretation, anyway...)

 Date: 9-JUN-21:30: Hardware & Peripherals

 Keyboard woes,

 Today, I got the news from my trusted local Apple dealer that my
 keyboard was dead. It seems that a week ago, it started to get
 confused about keystrikes.  Sometimes, it would not recognise the fact
 that I had hit a key. Sometimes it would take three "hits" before it
 would register. Other times, it would stutter, sending out a string of
 eeeee's or ssssss's even after the key had been let loose. The
 settings on the control panel were the same.

 Now, I've had my Mac for over two years now, and it has made the usual
 graduations to 512, and now enhanced. I think that I have taken good
 care of it.  Why should it go kaboom on me all of a sudden? Certainly,
 my son's hammering on it with the few games we have couldn't do it,
 could it?

 Being suspicious, I think it is just gummed up with dust. I think my local
 dealer might just be looking to sell me a new keyboard. This electronic
-hardware
 doesn't just break irreversibly, does it?

 Anyone else have keyboard trouble like this? Does it really mean that the
-whole
 keyboard has to be thrown out?

 When my Plus keyboard died with the same symptoms after only two weeks of use,
 the service guy here muttered something about some chip going south on the
 board.  I don't think the problem would have much to do with dust or actual
 wear, since mine did the same thing after only two months.

 IF you knew a hardware hacker who knows about how those things work, I bet
 that simply replacing the chip would fix the keyboard.  Apple just supplies
 a "kit" with a new board in it, and service sends back the old one, I think.
 I agree it seems silly to change out the whole keyboard because of a 29 cent
 part, but from Apple's perspective, it's easiest (not their money, either!)

 This is becoming a common enough situation, perhaps some knowledgable soul
 will enlighten us on what chip does what under the keys?

 It's an 8031 I think ... it should have an Intel part number on it, if
 you can easily see it.  Whatever the actual part number, it's a CPU
 with integrated serial channel and lots of I/O pins, and a fixed
 program in its memory.  I don't know if it is a standard part you can
 by off the shelf ... the fixed program may have been written to
 Apple's specs, in which case the part number on the chip will be
 something obscure.  The chip probably only costs a few bucks in the
 quantity Apple buys them in, but as you have pointed out, Apple is
 using a module swap service policy.  I guess that's one more reason to
 buy AppleCare!
