- With regards to the serial drivers... it is a VERY good idea to close
- your serial driver when you are finished. In other words, using
- RAMSDopen and RAMSDClose are strongly recommended. It is cheesy to
- leave the drivers open when your application terminates. Using the ROM
- driver does not allow you to close it without causing people to become
- sad :-(
-
- So, 1 - try and use the RAM based drivers
- 2 - try not to directly open driver's by refnum (-6, -7, -8, -9)
- use their name if at all possible (.Ain, .Aout, .Bin, .Bout)
- 3 - always always always close the RAM based serial driver when
- quitting your application. There is a means to insure that
- DTR stays high when closing the serial driver. Documented in
- IM IV.

-
- The "FKEY #4" command for printing dumps of the Macintosh screen is in
- the process of being abandoned in all Print drivers for the Mac. There
- are several reasons for this, which I can elaborate on if anyone is
- interested, but for starters it just plain doesn't work under some
- conditions not the least of which is:
- * low memory (applications assume 10k is plenty for any printer)
- * multi-finder (how do you print dynamically changing screens? 2
- screens?)
- * self portraits (how do you prevent FKEY #4 nesting?) Though these
- may be considered soluble at some level, it is not considered worth it
- since low-level print driver calls are being phased out.
-
- The recommended way of printing screen dumps is to execute an FKEY #3
- (which saves the screen to a file) then printing the file like any other
- bitmap file. This is not only cleaner, its easier and is just as fast
- as the FKEY #4.

-
- Running Finder 6.0, System 4.2 on a Mac II, I found this catastrophic
- Finder bug over the weekend:
-
- If the icon mask (second half of the ICN# resource) for a file is blank
- (all zeroes), attempting to drag the file in an icon view kills the
- Finder. Sometimes it bombs, sometimes it scrambles the screen,
- sometimes it just freezes solid - no mouse, no keyboard, no debugger.
-
- To fix the problem, use ResEdit to open the file which provides the
- brain-damaged icon. Open the ICN# resources, open the offending ICN#,
- and draw a mask. Close and save the file.
-
- The defective ICN# is also in your desktop file, so you can either
- (a) delete the desktop file while you're in ResEdit;
- (b) edit the desktop copy of the ICN# in question in ResEdit; or
- (c) hold the command and option keys while exiting ResEdit, so that
- the Finder will offer to rebuild the desktop.
-
- The program in which I found the problem is Mandelbrot Microscope, a
- color Mandelbrot set plotter. Only the saved set icon has this problem;
- the application icon and saved color table icons are OK.

-
- The most popular bug in device drivers is that they don't update
- dCtlPosition in the DCE. This only affects calls to the driver when
- relative positioning is used. The file manager always uses absolute
- positioning, but _DIzero uses relative positioning to sequentially erase
- the sectors of the volume directory on MFS disks. I don't know whether
- it uses relative positioning when initializing HFS disks, but it seems
- likely. The need to update dCtlPosition is documented in Inside Mac (in
- the Device Manager chapter, or perhaps the Disk Driver chapter), but
- it's just one sentence buried in a long paragraph.
-
- BTW, every ramdisk I've ever seen for the Mac (except the one I wrote
- for MassTech Development Labs, R.I.P.) has this bug. It took me a
- couple of weeks of experimentation before I hit on the idea that the
- problem was with a particular positioning mode.
-
- The only way to force a large ramdisk to be MFS is to build your own
- volume header. The sample ramdisk that was (is?) part of the Aztec C
- distribution did this. It's strictly against the rules, of course, so
- caveat emptor. I don't know any way to force a small volume to be HFS.

- The printing manager calls many other toolbox functions. The best way

-
- I'm not a HyperDrive owner, but I'd like to mention that when I was at
- MacExpo, just about every time I walked by the GCC booth, someone was in
- there complaining. This was the only booth where I consistently saw
- people (existing customers) not only upset, but at times yelling. This
- happened at least four times over two days, and it was never the same
- set of customers twice.
-
- The one time I stopped to watch to watch the sideshow, the person at the
- booth did a couple of really nasty things. First, when someone asked for
- the manager of the booth, the guy was told there wasn't one, and there
- was nobody for him to talk to. Second, when the guy decided to tell the
- booth lackey what he thought, the booth lackey walked off. Simply shined
- on this customer and went elsewhere. This, rather understandably so,
- pissed the guy off even more.
-
- The final resolution of this case was that a person who worked for the
- company that makes GCC's disk drives gave the guy the name of the person
- at GCC to call. Not someone from GCC itself, they were all at the other
- side of the booth telling people to ignore the idiot yelling in the
- corner. It was one of their vendors calming him down and giving him the
- information he wanted.
-
- This sucks, to say the least. The GCC folks were only interested in
- talking to prospective customers, and were not only unhelpful to
- existing folks,were downright rude, unprofessional, and in one instance
- abusive. If this is any indication of what the company is like, I'd sell
- my Mac before buying their stuff. The only feeling anyone watching this
- could come away from is that the only thing GCC cares about is getting
- your money -- once they have it, your on your own.
-
- And, for the record, it seems that their stuff breaks with every new
- release of Apple's software. GCC was the first company with a mac hard
- drive, and the last one to support HFS. You still can't run Multifinder
- on their earlier stuff, because they haven't ported it in. As a
- comparison, my ancient, cranky, Paradise 10 serial port runs Finder 6.0
- and Multifinder just fine, thank you very much. And it ran a LOT less
- than buying a GCC product would have. The difference? it is slower, but
- it works.
-
- If I were you, I'd buy anything else. And I'd find a dealer that tells
- you truths, not what it takes to make a sale. Dealers love GCC. High

- comp.sys.mac.programmer. How to install a programmer's button:
-
- On every machine EXCEPT for the Mac II, the programmer's button goes on
- the LEFT side, in the back, near the base. Get a flashlight and look
- into the ventillation slots of your machine. You should see two buttons
- between the louvres. This is where the programmer's button goes (on top
- of the buttons).
-
- On the Macintosh II, the programmer's button goes on the RIGHT side of
- the machine, in the back, at the base. I found it with a flashlight.
-
- The button near the front of the machine is REBOOT, at least on the Mac
- II. The button near the rear of the machine is DEBUG. You can probably
- test this with a penpoint. Anyway, install your switches so that the
- button labels match the appropriate buttons.
-
- It is IDIOTIC POLICY not to document this in the macintosh user's guide.
- I have never seen a machine WITHOUT these buttons installed. Apple is
- dreaming if they think they're doing someone a service! Every macintosh

- The stack sniffer is easily disabled by placing a zero in the global
- variable StkLowPt ($110-$113). The sniffer code then ignores the stack.
- When you're done, you should restore it to whatever it was so that the
- stack sniffer will start working again. I don't remember where this was
- documented, but it is a relatively well-known technique.

-
- I had asked if there was a YACC for the Mac, and I found MacYACC 0.3.
- But, it doesn't work well, and especially poor on a Mac II. Is there
- another YACC or a more recent version of MacYACC than 0.3?
-
- Please respond by e-mail.

- Thanks,

- Date: 31 Jan 88 22:50:29 GMT
- Organization: UinTech, Layton, UT
-
- The test lab I work in is looking at moving our analog data acquisition
- system from minicomputers (CCC ne Interdata) to micros. We have been
- looking at D/A systems for the PC/AT bus ('386 box) and for the Mac II.
-
- I would definitely prefer to do the programming on the Mac, but we have
- not been able to find much in the way of D/A cards for the Mac II NuBus
- yet. Our requirements are for 6 16-bit channels, with a max speed of
- 100Khz per channel. We will not be acquiring all channels at this
- speed, but one or two at a time will be required at ~90K. Also, we need
- some sort of tape interface for storing the acquired data on. We already
- have several good-quality 9-track drives, does anyone make an interface
- board for these for the NuBus?
-
- Any information this newsgroup can provide will be greatly appreciated.
- Reply via mail and I will summarize in another posting.

- Is anyone using MacNET? If so, what do you think of it? Is it
- enough better than (or different from) Compu$erve and GEnie to make it
- worth the bother?
-
- I already know that the rates are $8/hr, prime-time (7am-7pm), and
- $4/hr, non-prime, and there is supposedly no extra charge for 2400 Baud.

- Please e-mail to the address below, and I will summarize.

-
- I would like some information about a program called Protyper by

- price? I am particularly interested in its interface to Lightspeed

-
- I tried calling MacConnection, and other software houses to get a
