I've thought about hacking this up, but ye-olde time-compression has as
yet prevented me from. The best workaround is to boot the Lisa Pascal
Workshop (or Lisa Office System) and run the Preferences tool. The
next
best thing is to obtain a copy of XL Screen DA [from Dafax among
others]
which was developed by
Frederick Computer & Electronics Corporation
11301 Tree View Lane
Monrovia, MD 21770
While you are in the Pascal Workshop, disassemble Preferences and
reverse-
engineer it so we can get a real parameter RAM blaster under MacWorks!

Subject: Mac XL questions
>I would like to get some information on the Macintosh XL:
>* what does a lisa give you that a mac does not, and vice versa
- You get a bigger screen, which with the Screen Fix Kit (available
from
Dafax and Sun Remarketing) is extremely very much more usable than
the
one in a Macintosh 512K.
- You get a slower processor, which combined with the larger bitmap for
the screen produces a noticably slower computer.
- You get a lot of other features aimed at reliability. For instance,
parity-checked memory, not available on any other Macintosh.
- You get a machine which Apple never even heard of[anymore].
- With a Macintosh, you get the ability to make sounds, not just beeps.
>* what mac software does it not run
The aim of MacWorks Plus! is to have full Macintosh Plus compatibility
including the ability to run System 6.0, with a NOP'd Sound Manager.
>* where can you get memory boards (up to 4MB, no?)
I have heard rumors of a 4MB board. Ask on Genie. The 2MB board is
the AST RamStak, available at least from Sun.
>* can you add one of those 68020 expansion boards
Not so far as I know.
>* can you add a bigger hard disk
There are 20 MB internal drives available from Sun and external drives
using the 2-Port Parallel card sold by Dafax.
>* what kind of hard disk interface does it use
Proprietary.
>* how does it compare, performace wise, with a 128k mac? 512K?
Plus? SE?
The Macintosh is faster, but the RAM, hard disk and larger screen make
it
much more usable than the lugga-Macs.
>* are there interesting Lisa specific packages availible
There was a PenMacXL graphics tablet, but I do not believe anyone is
doing
commercial development for the Lisa today.
>* can the roms be upgraded, and to what level
>* what is the value of the Uniplus Unix implimentation for the
Lisa
If you find an "uninstalled" copy, I want one. Call me and make an
offer.
>* does it work with laser writer
Not UniPlus+ (but I think you mean MacWorks). The Lisa AppleTalks just
as
well as a Macintosh. Since all LaserWriter Drivers on a network should
be
the same version, wait for MacWorks Plus! and System 6.
>* does it work with the telebit trailblazer plus
I doubt it. Rather, I doubt it's worth it. Some terminal emulators
did a
steady 19.2 on pre-SE Macintoshes, but the developers had to hack like
mad
to do it, like bypassing QuickDraw. For things that do not require
screen
processing, like file transfers, there should be no problem. The
software
might still be so inefficient as to flat run out of steam, and you
could
find yourself benchmarking terminal emulation packages.
I own two Lisas. They do what I ask them to. However, why buy the
least
expensive (and slowest) computer running Macintosh software and then
ask
about all of the most expensive peripherals?

Subject: Fish! CDEV
Date: 2-AUG-06:09: Macintosh II
Last week I uploaded a CDEV called Fish! into the Mac II section. In
short it is a program that runs in the background and draws animated
fish swimming behind application windows. There is a color editor with
which to modify/create new fish. As is frequen tly the case, as soon as
we released the program to the general public, bugs emerged. Fish has
problem with system earlier than 5.0, multiple monitors, 256 color
monitors on 1-meg machines, some problems with other CDEVs, and with
changing the monitor depth while fish is running. Trying to run it with
systems earlier than 5.0 is certain death, the other vary from crashing
to trashing the desktop background. We're working on a new release as
much as our real jobs permit. In the meantime, exercise caution and keep
fish away from valuable data. (The worst thing we have heard about was a
trashed (5.0) system file.)

Ok you C dudes and dudettes --
We at NIC are the process of developing some INITs but we have come
across some problems and don't know exactly where to turn...
We're trying to using things like the dialog manager, get file, put
file, etc. etc. but it doesn't seem to want to work. Questions:
1. Is this possible? 2. If so, which it should be since I've seen many
INITs that do it... how? 3. Do we need to initialize the managers? 4. Is
the initialization of the managers automatic? 5. Are there any great
examples/source codes/etc. floating around, preferably
in Think C?
Thanks a lot in advance.

Subject: FSQueueHook Global
Date: 8-AUG-19:02: Programming Techniques
Does anybody know where the use of the FSQueueHook low-memory global (at $3E2)
is documented. I think it is used for intercepting all File Manager requests but I wonder whether the hook routine is called before or after the File Manager
request is executed and if the A0 register is guaranteed to contain the
parameter block for the File Manager call in question. Also, can I use the
ioTrap field of the standard parameter block header to determine which File
Manager routine I am intercepting and whether the strcture of the parameter
block is MFS or HFS?
Is it possible that Apple's documentation on constructing an External File
System has documented the FSQueueHook routine interface?
Thanks in advance for your comments.

I don't believe there is any public documentation on how FSQueueHook get's used.
Your best bet is probably to dig out the old MacNosy rom listings and see what
you can figure out. As a matter of fact i'm not really even sure that it hasn't
changed recently. You may also run into conflicts with AppleShare and possibly
other file server/sharer schemes because that's probably how they all work.

Folks, one of the members of my MUG found a virus in his home stack from some 14 year old. I will upload the script here. I found this "virus" in my Home stack
today...I'm not sure where it came from,although it seems likely it came from
something I've downloaded from GENIEin the past few days and discarded. The
"virus" is, as it states "harmless"in the sense that there is n o actual
permanent damage done, but I don't cons-ider this a harmless prank, and I hope
you don't either. I spent an hour andahalf today getting this thing out of all
my stacks, and I plan to have a wordwith the Sysop of the Mac board on GENIE to

you find this script in your home stack, make sure you lock yourhome stack

Subject: RE: Smalltalk V/Mac? (Re: Msg 2498)
Date: 19-AUG 06:12 Tools for Developers
Apple Smalltalk 0.4 is usable (particularly on a II; the performance on a plus I find too slow to allow me any forward motion :-)).
ParcPlace Smalltalk (the latest one, VM 2.3 release) is compatible with all Macs with minimum 2Meg memory. Quoting from frangible memory:
Dorado Benchmark = 100
Mac Plus 29
Mac SE 35
Mac II 110
(I believe this to be true... I am extrapolating from the VM
1.1 specs, VM 2.3 is a mite faster and there is one version for all machines,
unlike VM 1.1). In particular, the speed of (to me) the most critical part of a
development system, the editing, is more than acceptable even on the Mac Plus,
and down right cushy on the Mac II.
ParcPlace Smalltalk comes with a nice selection of tools for use with the Mac,
including some fileIns for reading/writing of MacPaint documents as Forms, color
support for the II, a PostScript output formatter for LW output, full
MultiFinder compatibility (yeah, lots of memory...) and an image can be quite
large - up to 16 MegBytes. If you are in need of supporting someing fairly
unusual, like weird IO drivers etc, there are instructions for constructing up
to 255 new User Primitives in MPW C and generating a Smalltalk interface to your
odd needs. The support is excellent, the people at ParcPlace are good (NOTE: I
am biased, friends work there) and the system is suitable for real applications
development.
By comparison: Apple Smalltalk v0.4 is a License 1 system in prototype,
ParcPlace Smalltalk v2.3 is a License 2 system, fully supported and nicely
'finished', which conforms to the Addison-Wesley source texts with many
enhancements and extensions. Apple ST is an on-the-fly interpreter, ParcPlace
ST is a true incremental code compiler with very slick tricks.
There is another Smalltalk product that is due out RSN from the Digitalk folks,
makers of Smalltalk V in the IBM world called Smalltalk V/Mac. Smalltalk V is a
subset of the Smalltalk-80 system with a slightly different grammar and class
structure and not quite as large a system. Their Mac system is a departure from
the A-W Smalltalk, utilizing instead a Macintosh Menu/Window interface. It's
supposed to be runnable in a 1Meg machine. I know little else at this point in
time (I've only seen announcement screenshots) and don't have much experience
with
Smalltalk V in any form to make any plus or minus comments. Others who have
been using it say that it is functional and projects have been completed
successfully with it.

disclaimer: I speak for myself, not ParcPlace, but I do have
friends there so I am a little biased. The apple st offering has the advantage
of being very inexpensive for learning st. :-)

Date: 21-AUG 23:42 Tools for Developers
I agree with you that Parc PLace Systems has a great Smalltalk system. It's the
BEST ,but you pay for what you get Apple ST costs $50 and PP costs just under
$1000 I think.I think that they should bring down the price to about $500 so to
compete with other debelopment systems. I think that Smalltalk is the BEST
language ever created and that now that we have FAST computers like the Mac II
it's time to start using it.But until it's relatively cheap it won't outsell
languages like LS Pascal or C that under $200 offer a good value. I know that
the Xerox liscense is expensive but they won't sell into the mass market with
those prices.Smalltalk is great for both beginners and experience programers and should be available for bot both of them.

You can change the system date format so it's 88-08-20 (or whatever) instead
of 08/20/88, but the problem is that Word must be using the short (numeric)
date format, instead of the long date (20 August 1988). Maybe you can patch
where word calls IUDateString, but the way Word handles traps, it'd probably
be real difficult to find this.

You're not going to want to hear this, but you're going to have to use the
Finder to copy Get Info comments. Under MultiFinder, the Finder keeps the
Desktop file (where such comments reside) open all the time, so at best you can
read comments. But, under AppleShare, there is no such file -- they're kept
in the desktop database files.

Apple provides an AppleTalk ImageWriter driver; I don't understand your

In Findswell, the INIT and the cdev are in the same file, so it's pretty easy
for the cdev to set a resource (like the short term memory setting). Screen
savers ought to be able to work the same way. You can probably change a
resource but never call ChangedResource, if you never want to write anything
(tho this requires keeping the resource file open).
Memory manager structures could change if Apple implements virtual memory or
extends the number of address bits.

That's a known bug, last I heard. What you want to do is avoid scanf on input.
Rather, use gets() to input the line, and sscanf() to parse it. Grotty, but
