     Subject: Need algorithms for Cell-organized graphics displays
     
     Does anyone have references for graphics algorithms (line
     drawing, polygon filling, etc) that have been optimized
     for use with subcell style graphics display (such as some
     terminals and many micros have)?  I know Barrett & Jordan
     have some articles in CACM (march,feb 1974) (I haven't read
     them yet).  Are there any others written since then?
     
     Thanks
     Bill W

Subject: Book.

The general opinion is to gear this book to the technical market-
place, the educational as well?  I am not that high on having a
loose leaf type book, but that could be for the second volume,
an update service on all the new machines that are around.

I would be interested in what one would want to see in a book
such as this describing personal workstations, what sorts of
things should be stressed and so forth.

Subject: Workstations - MicroDaSys 68000

There is a company in California called MicroDaSys, which claimed
in the latest issue of EDN to be selling a 68000 Unix system that
looks too good (and cheap) to be true.  Two 12mhz 68000s (one for
virtual memory management, with demand paging), and a 6809 for
interrupt-driven I/O.  Comes with 6 RS232 ports, running at up to
500k baud, and 4 parallel ports, with handshaking.

A multiuser system comes with 512k bytes of RAM in a 16M-byte
virtual space, 40M bytes of Winchester storage, and V7 Unix.
All for less than $20K.

Does anyone have any experience with these folks?  Are they
delivering?

Subject: Touch Panels: TASA

Product: Touch-Panel, x-y positioning
Price: $400.00 quantity 1, $150.00 in mass
Model: X-Y 3600
Principle: Capacitive Sensing, look at Xrx860 abortion
           60x60 steps in square surface 5"x5".

Probably useful in augmenting user work-effectiveness.
Address:  Touch Activated Switch Arrays, Inc.

          California, 95051
          (408) 727-8272
Contact: Bob Abler, manager of marketing.

I'd be interested if there is a demonstrated use for touch panels
that are not a part of the screen, and if they have the ability
to be used for Office Automation?  What also does one need from a
touch panel?  More x-y points ?

Subject: Mice for Apples

     Does anyone know of anyone who sells Mouses for Apples?
I presume they should plug into the game socket, and work like
a joystick plus the three button sensors.  A couple of micro-
switches on the side would be nice to determine which of the
paddle controls would be activated.
