Basically, the Vax drive will make single-sided floppies in RT-11 format, and then I can read them on the Perq's. However, there seems to be some kind of format problem. When I format the floppies on the Perq using the "floppy" utility (single sided, single density) and then use "arff" on the Vax (under 4.1bsd Unix), I get a directory which has garbage at the end, although "arff" can read and write to the floppy still. When I put the diskette back in the Perq, the whole thing is munged so badly that "floppy" cannot read anything off the diskette. The only way the thing works is to use "flcopy" on the Vax to copy a good disk onto my blank floppy, then use "arff" to delete the contents, then use "arff" to add the files I want. This is tedious and long. I need a way to properly format the diskettes and make this whole process a little easier. I have lots and lots of files to move and any suggestions/code/pointers will be greatly appreciated. Thanks in advance.

You can get a stand-alone trackball box (similar to a mouse) of the shelf with your choice of 1, 2, or 3 buttons. Also, if I recall correctly, your choice of analog or digital output. -Rich Zellich ------------------------------ Return-path: <harpo!floyd!cmcl2!philabs!sdcsvax!sdchema!jmcg@Ucb-Vax> Date: 8 Apr 83 3:28:47-PST (Fri) From: harpo!floyd!cmcl2!philabs!sdcsvax!sdchema!jmcg at Ucb-Vax Subject: thumbpads vs. mice On older Xerox office automation products (earlier than Star), they had a device they called a "mouse". It was a finger pad to the right of the keyboard. It most resembled a joystick*: the position of your touching it determined a direction and the contact area supplemented the distance from the center to produce a magnitude. Small, slow adjustments were made using a light touch of a fingertip; large, quick movements were made using four fingers flat. I've always thought they put it in the wrong place. Where I would want such a thing is under my thumbs in front of the space bar. That would solve the problem of having to remove a hand from the keyboard to use the pointing device. It could easily fit in the palmrest area found on these new "ergonomic" keyboards. Modern mice appear to be best for drawing; for pointing, I'd like to see how this thumbpad idea would compete.

At the start of each game I had to wiggle the mouse around to re-establish eye-hand coordination, but then I feel I was much faster than with a track-ball since I had all the kinesthesia of my arms muscles for fast accurate positioning. ------------------------------ Return-path: <byard@bbn-unix> Date: 10 Apr 1983 15:10:22 EST (Sunday) From: Larry Byard (WSE-EUR) <byard at dca-ems> Subject: Track balls vs Mice I am on a business trip at present and I'm stuck with a TI 700 instead of my CPT word processor so this will be short... I used the Navy Tactical Data System for three years. It had a track ball which worked quite well, with practice. And by the way it had buttons, right in front of the ball. I have also used the mouse on Xerox's Star Work Station. To me, the mouse is the winner and it is also much easier to learn.

'Nough said. I worked on a graphics system in 1981 which used track balls with three buttons. I have not had experience using mice, but I believe that the track ball buttons are less useful then mice buttons -- it is hard to position the cursor while holding down a track ball button. B.J.

Put mouse trackers (wheels, ball, optical device) under each half. One side slides your window around or does long cursor positioning. The other one does fine cursor positioning. Ok, for a truly portable workstation twist each half of the keyboard around and mount them on the back of your flat panel screen, top rows in. Got that? Now which would be better: 1) putting trackballs under the palms of your hands or 2) leaving the mouse trackers to roll on the back of the panel attached to the keyboard halves somehow? -- kirk ------------------------------ Return-path: <FJW@MIT-MC> Date: 10 April 1983 15:42 EST From: Frank J.

I believe the discussion proposed in this message properly belongs on WorkS and I will attempt to divert responses to this list. --Frank -------------------- Date: 10 Apr 83 04:15:21 EST From: MBF at cmu-cs-c.arpa To: info-micro at brl.arpa cc: mbf at cmu-cs-c.arpa Re: Suns, etc... I second the motion put forth in an earlier post: John Gilmore et al, show us your stuff! As a soon-to-be consumer of hi-tech workstations, I for one would like to see (on this list, in a technical journal, or from one of the workstation concerns) a comprehensive list of capability comparisons between such systems as the new 68010-based Sun (Sun II?), the Apollo Domain (including the new, "inexpensive" system), the Perq II ("inexpensive" version, too), and the like. For a class of personal workstations with some major similarities, these machines have many differences at different levels. Perhaps someone who has extensive experience with two or more of the machines could post his opinions? When will the 68010-based SUNs be in available on a production basis? How about EMACS and Franzlisp? How good is the SUN mouse? How about distribution, maintenance, software updates? What's the truth about paging over an n-machine ethernet, for small and large n? How about when the ethernet is used simple for file accesses and paging is done using a local disk? Without actually doing statistical analyses of the disk in question and a 10M ethernet, I don't know the *facts*, but it seems conceivable that, for small n, a 10M ethernet could compete favorably with garden-variety winchesters (5-7 MBit/sec transfer rate) in average access, latency, and transfer rates... but who has the real lowdown? It would seem that the new Perq-II is a better competitor with the 68K systems than the previous machines from Three Rivers.... A recent blurb in Electronics magazine claims 32-bit demand-paged virtual memory, "Unix" of some (unnamed) flavor, 2M main memory (standard!), a 32-meg winchester, and a large (20 in.) landscape monitor with at least the same bit density as their earlier portrait monitor (which raises screen resolution to 1280 x 1034)! Also, they claim a minimum-configuration system starts at $13.9K!! It remains to be seen what is meant by "minimum configuration". Does anybody have any details? Is this machine really available? I feel that more information is needed to make an intelligent decision than the euphemistic literature available from the manufacturers. Any information along these lines would be helpful (as long as it's within the bounds of suitability for the list). happy hacking, Mark Dzmura via mbf@cmu-cs-c ------------------------------ Return-path: <SIRBU@MIT-XX> Date: 11 Apr 1983 1417-EST From: Marvin Sirbu <SIRBU@MIT-XX> Subject: Portable terminals To: Telecom@USC-ISI, Neuman.ComRes@MIT-MULTICS, Pool@MIT-MULTICS The annual report of Motorola contains this note of interest: [Motorola] has developed a unique land-mobile radio/data communications system which gives users access to computers while on the move. The basic element of the system is a handheld computer/data terminal containing both a radio and a telephone modem. The system's intelligent network controller directs messages between a large fixed computer and the portable user, and controls the operation of the radio network. The portable computer/terminal ... features read-only and random access storage, a two-line liquid crystal display, and an alphanumeric keyboard... The first customer, IBM has contracted for a system to be used by its field service personnel. The IBM system will consist of approximately 250 separate citywide radio networks, coordinated by 20 intelligent network controllers, each interfacing with the IBM nationwide computer network. Each controller is capable of supporting up to 1,500 portable users. Installation will begin in late 1983 and is scheduled for completion in 1985. The article doesn't say whether packet radio or some other technique is being used to control access. Coupled with the recent FCC decision to liberalize the use of SCA's, we may see even more of this kind of thing. ------------------------------ End of WorkS Digest ******************* -------
