Also, the 010 has a "loop mode" which uses a 3 word (6 byte) on-chip
instruction cache to speedup small software loops. Tiny 3 instruction loops
can run up to 50-80% faster according to the Motorola documentation included
in the Lha archive below. Keep in mind that typical OS and application program
code executes a general mix of CPU instructions, so such loops represent only
a small part of a typical program's code

Actually these are TWO instruction loops consisting of three words. This
same feature Specifically it can be any ONE word instruction combined
with any variant of the DBcc (usually DBF) instruction. The DBcc is a one
word opcode with a one word branch offset. The most obvious use is for
block moves. The DBcc instruction can break out of the loop using a count
or a condition. If you don't want a condition, you use DBF. F stands for
false, which means it never breaks out of the loop except for the
counter. This example copies bytes as long as they are not equal to zero
and 16 bit counter in d0 is not -1. The weird terminating number is used
to allow you to nest an outside loop that would allow a 32 bit counter.

lea SOURCE,a0
lea DEST,a1
move.w #LENGTH,d0 <---example wrong. s/b #LENGTH-1
LOOP move.w (a0)+,(a1)+ ; this section will run super-fast
dbeq d0,LOOP ; because no instructions are fetched

Is the audience asleep yet?

I have a little tidbit of info for your viewing pleasure about the
Macintosh II. Very nice machine and all (we're talking 6 NuBus Slots
here!) but there is a little problem. The II came with an 800k Floppy
Drive and is not 32-bit clean. You may think Mode32 will solve the
problem but it doesn't. To Make the 020-based Mac II clean, you need
something called the SuperDrive/ROM Upgrade. This gives you the 1.4MB
Floppy Drive and a PMMU for Virtual Memory. It also makes the machine
32-bit clean by adding a new ROM chip. Good luck finding the upgrade...if
your machine doesn't already have it then you might be outta luck. You can
test for the upgrade by inserting a High-Density Floppy Disk into the
drive. If you get the "disk is unreadable" message then you don't have
the upgrade.

Good luck with your Mac II!

I have been serving the very rare Apple Service Manuals from my FTP at:

ftp://ftp.traffictrak.com/ServiceManuals/

Even manuals to oldsters such as the Macintosh 128 are available.

Due to some idiosyncrasies of my router, some people can't seem to access
my FTP when not using passive mode. For them the service manuals now are
found on a web page:

Maybe not. If the HD has a custom ICON then the HD might not appear in

Disk Rejuvenator can fix that.

http://www.umich.edu/~archive/mac/util/diskfile/diskrejuvenator1.0.sit.hqx

But how can this be done with System 6?

Connectix Optima allows 32 bit addressing with System 6.
I have been looking for it for years.
Somebody on a list said that Connectix doesn't have it.

Connectix Maxima allows access to 14 MB of RAM with System 6.
It does this by using "Enhanced 24 bit addressing".

ftp://ftp.accesscom.com/pub/users/g/gamba/Maxma203.sit.bin

Version 3 is said to have more features than version 2.

In System 7 on a Mac II, Mode 32 won't access more than 8 MB of RAM unless
a 68851 PMMU chip is installed in place of the AMU chip.

When I read the latest Classic Macs digest, I noticed I forgot to specify in
my post the "second" potential problem with installing a 68010 in a 68000 Mac.
Which is, of course, software compatibility. The document in the lha file that
I mentioned discusses this in some detail. The Mac's ROM and SSW both would
need to be compatible for the upgrade to work.

The "MOVE SR,<ea>" instruction might not be an issue on 68000 Macs. I was
under the vague impression that, on a 68K Mac, the CPU is always in
supervisor mode.

What the Symantec rep told you was not correct. You should now speak
with a supervisor, because the person you spoke to is apparently not
a seasoned employee.

My copy of NUM3.5.3 is only about ONE month old, but my circumstances
for obtaining it is not the same as yours. My packing slip has an
item number you can use. Have them check for Item# 07-83-00100. I
know they have many copies, because they tried sending it to me a few
times, but Airborne returned them to Symantec due to shipping errors
by Symantec. (I know they were all shipped, because I have tracking
numbers.)

NOTE: You may not use any information in this e-mail with any
association to Apple. The information I have provided should be
available from Symantec upon request.

I hope this helps.

P.S. Make sure you get the name of the person with whom you spoke and when.
P.P.S. You can make bootable NUM disks from the CD with its "System
Disk Builder" program, which requires a Disk Tools disk (part of your
Mac's original packaging) or any other bootable disk.

I don't know if there is a hardware limitation about SCSI disks with the
classic II

The Classic II is limited to 4GB with Mac OS 7.5 (or higher,
including 7.6.1). Because PCI Power Macs can go up to 2TB with Mac
OS 7.5.2 or higher, the 4GB limit is presumably a hardware limit.

But beware there is a software limit: system 7.1 can only handle disk under
1 gig

Actually, Apple reports that prior to 7.5, the OS has a volume limit of 2GB.

I hope this helps.

Thanks for pointing that out, Sue! Yes, Robert, how did you get your
SE/30 to run Mac OS 7.6? The 7.6 box says that it won't run on an
SE/30.

Has anyone tried installing a universal version of 7.6 onto a clean
hard drive from another Mac (that can run 7.6), and then using this
hard drive in the SE/30? I don't remember if we've discussed this
already...

No, I haven't, and the hard drive on my PPC at this point in time
only works with the drivers from 8.5 and above, so I no longer have a
machine I can try that on. But post it to the list and see if someone
can make it work. Worth the price of another 68030 to get 7.6 on that
baby, if it will run properly once it's there.

Just for fun,

http://bellac.dyndns.org/router.html

Has a neat writeup about using your SE30 as gateway/router. I'm going to
break down, buy a 56k modem, and set up a LAN and will try the SE30 first
(instead of a Win98 box running Internet Sharing). That way I can run my
own ftpd or whatever if I want, something which (I believe) the Internet
sharing in Windows won't allow me to configure.

Good point! I had forgotten about that! Amber I have not found any other
worthwhile answer besides "there is a problem". I will bet James' suggestion
will fix it for you.

I have purchased all kinds of old Mac batteries from a place local which
sells nothing else but batteries. I am sure there are many of these places
around the country (USA).

Thanks!
G.

any idea why my Mac IIx with the color card only displays grays?

If after shutting down your Mac and turning it back on reverts the
colors back to grays, then you probably need to replace its
batteries. The IIx uses two 1/2AA 3.6V Lithium batteries.


Subject: Mac IIfx problem
From: GLENSTREK
To: Classic Posts
Date: Wed, 17 Jan 2001 19:58:49 EST

Hello all,

My rock solid Mac IIfx froze today while running FileMaker Pro 4.xx. Forcing
FM Pro to crash.

This machine usually goes for months on end without any problems.

Running Norton 3.5x and Disk Warrior indicated no problems.

FileMaker is the database for my small business. All sales records, accounts,
inventory, purchases --everything is in the data files and the records go
back to 1989. The good news is I have multiple data backups.

After the crash, FileMaker indicated some data files could not be read on the
hard disk and that requires a forced quit of FM Pro. When FM Pro is not quit
properly is tends to corrupt the data files. So far the FM recover function
has worked on the corrupted files.

When I attempt to restart or shut down the IIfx I get a message cannot
restart or shutdown because <unknown application> will not quit. If I force
quit -- Finder quits and restarts. So I have to use the power off switch to
shut down.

I tend to think the HDD may be the problem (have not had the chance to run a
low level test for bad block yet).

I'm setting up an external HDD and will transfer the valuable data files to
that drive for the time being.

--Just wonder if anyone has any ideas as to what may be causing this problem.

System Spec's:
Mac IIfx (upgraded from Mac II), 80 MB RAM, IBM 500 MB HDD (3 volumes), MacOS
7.6.1. Raster Ops Video Card driving a SUN 19" (GDM something) Hi-Res
Monitor; SCSI chain: external CD-ROM and SyQuest 135 Removable drive;
Ethernet with 5 other Mac's.

Thanks --glen
