I don't know if it will work with the new ROMs, which keep the cursors in ROM rather than in RAM.

Unpack this file, turn up the speaker volume, and run the Typist application; your Mac will immediately become an Underwood mechanical typewriter (or so your ears will insist)!

We would also like to be able to connect our unix system (AT&T 3B2) to the laserwriter. For now, we connect the 3B2 to the RS232 port of the laserwriter and manually change the switch on the back panel from Appletalk back to RS232. If this switch could be done in software, this would be much better. If there was a bridge from RS232 or parallel port to Appletalk this would be even better. Another possibility is that the Mac could connect to the Laserwriter through the RS232 port and then we could use a printer multiplexing box to share one printer from several hosts. This does not seem easy to do since when one selects Laserwriter as the printer, Appletalk is enabled. Any help, suggestions, etc. would be greatly appreciated.

When he wrote it, it was called ExitToShell (or "ETS" for short), and its original intention was to tie the interrupt vectors to the Reset button. That was not such a great idea for the following reasons: 1) The RESET button is necessary for situations where a simple call to ExitToShell won't work or the machine is really hung, and 2) It didn't work that way. Alan finally decided to use the back (interrupt) button. So you ask, "What do it do??" It's simple: ExitToShell (aka CrashSaver) ties the higher-level interrupt vectors (interrupt levels 4 thru 7) to the ToolBox routine ExitToShell (hence it's original name). ETS doesn't need to be run as startup application, but it is most convenient if you do. Otherwise, run it before you start work. ETS is almost completely effective. There are situations from which ETS can't recover, for example when the screen fills with snow and the speaker starts chattering, and sometimes the machine locks up after exiting to the finder, but those instances are rare. I use it with everything I own, and I have not had any problems caused by ETS. --richard ------------------------------ Date: Wed 5 Mar 86 10:44:49-EST From: Rich Subject: Serial Port Interfacing > Does anyone have or know where I can find routines or programs written in LisaPascal that talk to the serial (modem is fine) port on a character-by-character basis? I am trying to write a software interface to a Kinetics 3989 crate controller, but I can't get the serial stuff to work. Any help (program fragments, etc.) would be greatly appreciated. --richard ------------------------------ Date: Wed 5 Mar 86 10:46:15-EST From: Rich Subject: Double-Clicking How do I use the Event Manager to detect a double-click?? --richard (rs4u@te.cc.cmu.edu, rs4u%andrew@te.cc.cmu.edu) ------------------------------ Date: 7 Mar 86 10:28:24 EST (Friday) From: Paton.WBST@Xerox.COM Subject: Re: Mac Magazines Again MacUser is not bad, but there was an article on FEdit in an early issue that was completely messed up. On the newsstands, you can find Nibble Mac, published bi-monthly by the people that publish Nibble for the Apple II series. They publish programs(usually in Basic). However the best is probably Mac Tutor, which is available by subscription only. It publishes programs in C, Pascal, and Modula-2(and possibly Basic). Art [NOTE FROM MODERATOR] I agree with your review of MacTutor, but I don't think that it's available by subscription only, I get it at my local Mac store (ComputerWare, Palo Alto, CA) [END OF NOTE] ------------------------------ From: bellcore!decvax!wang!ephraim@ucbvax.berkeley.edu Date: Thu, 6 Mar 86 17:48:58 est Subject: Animation on MacPlus In info-mac volume 4, number 24, D.D.Warner asked why many animation programs do not work on the Mac Plus. I can't say for sure, but I expect the answer is connected to failure to adhere to Apple's hardware-independence guidelines. Every program I have seen that uses the alternate screen buffer expects it to be at a fixed address. Most of them look for it at its 512K Mac location; Fokker Triplane addresses it at its 4Meg Mac location and depends on wraparound to do the rest. Nobody (that I know of) uses the alternate screen based on Apple-provided low-memory pointers. So, many animation programs are broken on the Mac Plus. Fokker Triplane is only broken on machines where memory wrap-around doesn't work, such as my 1.5Meg Mac. ------------------------------ Date: Thu 6 Mar 86 21:35:00-PST From: Jyh-Jye (Juoming) Yeh Subject: slow clock problem Does any one know what happened to the mac when the clock is 3 times slower than usual? It occured to me that my Mac's clock is always wrong. I replaced the battery but it didn't help and the Mac now takes 33 seconds to count 30 seconds. Any hint? Thanks for any suggestion.

Date: Fri, 07 Mar 86 12:00:27 -0500 From: Gurudatta Parulkar I have a simple question which might have been answered before, but I couldn't find it in whatever archives we have. We have recently got few 800k drives and I tried connecting them to Mac directly as external drives, and they don't work. Mac keeps insisting that I reformat the single sided disks,and when I try doing that it says that formatting failed. The same drive works fine when connected to 20MB hard disk. I haven't received any documetnation which talks about any such problem so any help will highly appreciated. -guru :______________________________________________________________________________ :Gurudatta M.

Date: 06 Mar 86 10:16:33 PST (Thu) From: homeier@aero A while ago I heard a rumor about a new version of the Macintosh being planned by Apple, which would feature color, named "Jonathan". Does anyone have any information about this? Even rumors would be encouraging. I would be interested in what processor it would use, how much memory, the resolution of the screen, the range of colors, etc., in other words all the good stuff. Also, when might such an animal become available to us, and are there any guesses as to how much it might cost? I have always loved the emphasis of the Macintosh on graphics, instead of the gray PC emphasis on text. In my opinion, color would magnify the Macintosh's attractiveness many times.
