Subject: Mac II - Beyond 8Mb RAM

Hello from Tasmania. This is my first post here. I only discovered the list
recently although I've been using Macs for 11 years.

I've just gone from 8Mb(8*1Mb) to 20Mb(4*4+4*1Mb) on an 800k drive Mac II.

You definately need a PMMU chip (68851) - or an accelerator with one, say a
68030 based one, which has the PMMU built in - for more than 8Mb.
Simms greater than 1Mb need to be PAL simms (for the II & IIx), and only go
in bank B (the 4 closest to the Nubus slots). These simms have an extra
little ninth chip which is about a third the size of the other 8 on the

You also need the Mode 32 extension (32 bit addressing) to 'see' more than 8Mb.

The Mac IIx ROMs allow you to put the bigger simms in bank A as well. You
can go to 68Mb(4*16+4*1MB) without them, 128Mb(8*16Mb) with. IIx ROMs and
the SWIM chip allow you to use a Superdrive (1.4Mb floppys) or two (you
have effectively made a IIx).

If you have a Mac II which already reads 1.4Mb floppys, you already have
the FDHD Upgrade (IIx ROMS, SWIM chip and Superdrive). To use more than 8Mb
of RAM all you need is a PMMU and Mode 32.

If you don't have a PMMU you have an AMU. They both go in the same place
between the 68020cpu chip and the simms. It's 34mm sq. My AMU has 8709A,
VE791, 3 4 3-0002-1 on it. I think the PMMU would have 68851 on it.
You can find PMMUs at for US$49. They also have

I use their Diimo 030 (50Mhz '030 & 50Mhz FPU & 64k cache) which I'm
reasonably happy with, although the cache has been crashing my Mac.
(anybody else had that experience?)

I got my 4Mb PAL simms for US$26 each, and I think I've seen 8Mb ones for

My advice? If you want a bit more memory (presuming your at 8Mb now) 20Mb
is lovely, it gives you that extra room to run almost any application
without having to fiddle with the Extension Manager (well not for space
anyway, maybe for speed). 4*4Mb PAL simms & PMMU = approximately US$150 +

You could just get the PMMU and use virtual memory or RamDoubler for more
than 8Mb. US$50+p

Mac IIx ROMS and a SWIM chip (or a whole IIx logicboard)? I wouldn't bother
unless you need more than 68Mb of RAM or a Superdrive. = approx. US$70
(maybe less) each for logicboard and Superdrive
If you have a need for that much RAM you need a faster Mac for it too.

I just use my Classic II (10/100) for 1.4Mb disks and transfer it across
via AppleTalk, Zip drive or stuffing and putting the file on 800k floppy.
It's also handy having a second Mac going for all sorts of things like
application manuals, waits during Internet downloads etc. Consider getting
a Classic or early PowerBook.

For speed and memory a 68030 based accelerator could be the answer, I've
seen some cheap used ones in the US. (I can't believe how cheap stuff is

I'm pretty sure the above is accurate.
For what it's worth I subscribe to MacAddict, and I've found their articles
on this subject (and regarding the LC) to be hopelessly inaccurate, one
said you need an FPU to run virtual memory on the LC!

In response to:

Subject: Beyond 4MB RAM

I have a Sonnet accelerator for my Macintosh Classic. It says it can use
more than 4 mb of RAM, but that is only with Virtual Software from Connectix.
Apparently this is an older software, because neither Sonnet nor Connectix
lists it. Where can I get it?


You probably need Virtual 3.0.2. I am attaching the "Virtual Installation
Disk". If you put it on a diskette you must use a low density one (800K) And
it's exact title must be Virtual Installation Disk. If you don't do this, the
installation process will tell you that you must insert an original disk. You
can copy it with DiskCopy 4.2. I , which will make an exact copy. You can
only copy it onto an 800k diskette. I don't know why. I have it on loan from
Tim at PacificMac who was most helpful in suggesting that this would solve my
problem with the SE's not being able to use more than 4mb contiguously
although I have 16mb installed. I am going to use it to get my SE with an AE
accelerator to see more than 4MB contiguously. I have 16MB installed an the
AE accelerator allows me to see that I have 16MB, but any particular program
can only use up to 4mb, although I can run several programs at once. Good

1. I do not have any software that can recognise an IBM disk
in the superdrive. Was this in the standard system?

You won't. This was not standard on Mac System software until 7.5.You
will need a third-party product (like AccessPC) to do this.

The Performa versions of 7.1 came with PC Exchange - my Performa 475 had PC
Exchange with B-7.1P5 when I got it (I'm on this mailing list because of my
mac Portable, Mac Plus, and 512Ke, none of which are using any version of
System 7 because of an absence of working HD drives...)

Subject: Classic II Weirdness?

I presume that the date/time batt needs
replacing - does anyone know what the battery type is, where it is located
and what the procedure is.
Thanx for your help.

Dear Patric,

They are comonly available at Radio Shack in the US. I don't know if there
are RS stores in the UK.

Radio Shack is called Tandy in Britain, where RS refers to `RS Components'
(formerly Radio Spares) which is a large industrial supplier of electronic
bits. RS stores are few and far between, only sell to trade customers, and
do stock the batteries. The one Tandy shop I tried was as much use as a
chocolate teapot as far as lithium batteries for Macs go.

Maplin is a better idea in England at least - I don't know whether it has
any shops elsewhere.

Subject: Reformatting

I've got a Mac Portable with a locked disk and a long forgotten password.
Does anyone know how to get past DiskLock (an early version) or, barring
that, know where I can get a utility to reformat the Quantum 160 HD? I've
already tried a diskette with another system on it and it just kicks the
diskette out.

The display on my old MacPlus is failing. A friend of mine went through
this with his and said that he had the power supply replaced.

Does this sound right? If so, where can I order a new power supply from?
Can I replace it myself?

I just purchased a Carrera 040 accelerator for my IIci running 7.1. I am
very SLOWLY working out all of the kinks (which of course I was not warned
about in advance by MicroMac).

If anyone else out on the list has been through this already, please email

specific questions to the list for some possible help.

Hello All

For those of you who want to get on the web with a browser on a Plus, SE
or SE/30, Portable or other 68000 series Mac, here's the URL for the
MacWeb browser and all the extensions and control panels you'll need:


It will work with Macs with 2 megs minimum.

Re: email program for 9 inch Macs?

I am aware of Eudora and such that use MacTcp and PPP?
Is there any other way?

If you can connect to a BBS that has internet access via a direct
dialup *OR* via telnet, you might find an offline mail program
called Alice (for the MAC) which is "Blue Wave Compatible".
Blue Wave is a DOS/0S2 application and is very useful, but
dying out as the Internet overwhelms Fidonet and BBS's in
general. If you can telnet to (which is in Texas) you
can setup a BBS account for free. You might also be able to
find the latest version of Alice, which I believe is Alice 2.4.2

If you want an alternative TCP/IP mail program there is a
FREEWARE program out which has DOS, WIN3.1, WIN95,
and MAC versions. The name is Pegasus Mail, and can be
ftp'd from if you
are in the U.S.A. or other sites from other parts of the world.

Subject: MacPlus/mounting a hard disk

I just found an Apple Hard Disk 20 (model M0135) that looks like it connects
to the floppy port of my Mac Plus. I'm not sure how to go about testing
and/or using this drive. Will I need to initialize it? How will I know if
the CPU is recognizing it? I assume I would need some utility for such
things. Any advice would be greatly appreciated.

Brian Robson

I've got one of these and it still works very well. Earlier versions of
System 6.x software contain the "Hard Drive 20" extension/init that you
need for it. It can be initialized/reformatted with the OLD versions of
the Apple HD SC setup utility included with System 6 software. And yes,
the Mac will treat it like a big floppy. You'll know if the CPU is
recognizing it because its icon will (same as Mac hard disk icon) will
show up on the desktop. My Mac Plus boots from this drive.

Can MacTCP-PPP and Eudora run under system 6 Software? System 6

Check these text files for useful info:

Here's an extract from the Mac Internet FAQ:

If you want to use System 6 and connect via PPP, following software
versions work even with 1MB RAM: System 6.0.5-6.0.8 (MacPPP 2.0.1 insists
that System Folder's name must be "System Folder" so if you are using a
localized System change the folder's name accordingly), MacTCP 2.0.6,
MacPPP 2.0.1, NCSA Telnet 2.6, Fetch 3.0.3, Eudora 1.3.1 (install also Map
control panel from the System disks and set your time zone), NewsWatcher
2.0d13m01, Internews 1.1, MacWWW 1.03 (Samba), MacTCP Watcher 1.1.2 (older
versions of these apps may use less memory).

MacWWW 1.03 (Samba) works on 68000 macs (at least on System 6.0.5 - it
crashes on System 7.0.1*). It opens fine, loads the startup page fine
(doesn't know how to read files from disk, text-only, no ISO 8859-1
translation, opens a new window for each link). Do not close any windows as
this crashes the mac; also quitting MacWWW seems to cause a crash.

Note that with System 6 MacTCP may crash when saving prefs for the first
time so check that the prefs are actually saved.

To save space on a floppy-only system, install a minimum System for your mac
and delete all System Folder items except System, Finder, PPP, ConfigPPP,
MacTCP, PPP Preferences, MacTCP DNR and MacTCP Prep; delete also unnecessary
fonts and DAs from the System file with Font/DA Mover (keep Control Panel DA,
though) - this leaves 322 K of free space on a DD floppy with System 6.0.5 US
(MacPlus minimum install).

Unfatten also "fat" tcp-apps. Turn RAM Cache off
to leave maximum amount of RAM to the apps.

Good luck,
Chris Adams.

Acting on the tip from Rebecca and Rowland, I tried the trick regarding
the differing file systems. Here's what I did:
1) I booted the MacPlus from a startup disk (disk #1) that I already had.

2) I copied a system folder from my Performa onto an 800k floppy (disk
#2), after erasing said floppy on the MacPlus.

3) I ejected the startup disk from the MacPlus, and put the floppy(disk
#2) with the new system in. Then I ejected that one, and put a blank disk
in (disk #3).

4) I copied the system folder from disk #2 onto disk #3. I then
restarted the MacPlus. I inserted the new disk with the system folder on
it (disk #3), and it was promptly rejected.

There are some issues you should be aware of...

1) The system for a Performa is for a 68020 or 68030
and will probably not work on a 68000.
Your best bet is to install system 6 on a floppy on the performa.

2) Copying an active system file under system 6
would sometimes not be done properly.
This has somethind to do with open files.

I am not sure what you are trying to do,
but the system 6 switch is undependable with differt versions
of the system. (i.e.6.0.6 vs 6.0.8)

System 6.0.8 install disks are available on the web.
Also availabel on old "Nautilis" CD's that came with older performas.
