Hello net. Here is another "Anyone interested" posting.
App*eTalk on an Amiga? We have a contractor here (Harold of NTT systems)
who says that it would be fairly easy to run this protocol on the Amiga,
given an RS232 to current loop convertor, which I could whip together in
(almost) no time flat. He doesn't know if he wants to put this thing out PD
or as a marketable product, so we are looking for feedback from the net.
Comments?
Framebuffer: I asked for input a while ago and got only one response,
namely Chuck McManis. (thanks Chuck - I'm going to mail you) This project
(along with others) is on hold until the end of sailing season, but I will
be doing paper type work when it rains. I am considering using the DP8500
Raster Graphics Processor from NSC (if it's not too expensive). Comments?

I think it's a great idea - I could drag an Amiga into work, hook it into the existing LocalTalk (that's AppleTalk protocols on RS422 lines, it's EtherTalk on Ethernet) net, and not only show off the capabilities of the Amiga but also show how it can use the existing hardware to file serve off of, use existing laser printers, etc... Cavaets: 1. Can the Amiga serial port run at 270K baud (that's roughly the speed of the LocalTalk RS422 links). 2. To make it useful, you need to also implement some of the higher level protocols, like Appleshare etc. Has anyone tried an PC Appletalk board in a Amiga 2000? Mark (Fausett@radc-tops20.arpa) -------

The speed at which you could drive the Amiga's RS232 port through the serial.device would make this a horribly slow solution, if workable at all. Perhaps it would be possible to build a parallel<->RS422 converter so as to get acceptable speeds (I don't have Hardware RKM handy, but you might be able to draw the power you need directly off the parallel port. Maybe not, though). Mark (Fausett@radc-tops20.arpa) writes: > Has anyone tried an PC Appletalk board in a Amiga 2000?

MicroBotics is doing a board called 5Power, which will have (among other things) 2 or 4 serial ports on it, using the same chip as Apple uses in the Mac, and each serial port will have it's own dma channel to memory. It should be easy to do for that board. -- Randell Jesup, Commodore Engineering {uunet|rutgers|allegra}!cbmvax!jesup

I'm not sure, but I suspect some of the desktop publishing programs will do this. If you'd rather use a regular word processor, there is a PD Postscript printer driver you can use, and redirecting printer output to a file can be done several differnt ways. If nothing else, there is a PD program that will replace the printer device with one that will save to a file instead of going directly to the serial/parallel port. > * Are there programs (pd or otherwise) readily available that > will do a dump of raw data over an AppleTalk network to a Laser- > writer (i.e. without passing it through an application first)? Although I haven't used it, we have a program called PSdump for the Mac (I think it's PD) which is supposed to dump raw postscript files to Apple*alk laser printers. I don't think this is a foolish proposition at all. I have an Amiga, and do something similar. Rather than going through a Mac, I use the 25 pin serial port on the LaserWriter, and send from my Amiga over our campus network. This method gives me excellent results, and printing takes only as much time as it takes for me to change the switch setting on the printer, and connect to it via the network. Besides, I like the WP program I've got for the Amiga more than any of the Mac WP programs I've used. If you do go the Amiga route, I can dig out the specific progam names you need. Happy decision making. --------------------------------------------------------------------------- Steve Ludtke stevel@tybalt.caltech.edu ..!cit-vax!tybalt.caltech.edu!stevel stevel@citiago (Bitnet) OBS949 (Amer PPl lnk) 72335,1537 (Compuserve) XJM16487 (Genie)

Execelence! the new WP says that it supports postscript 100%!! And it does have
the ability to dump to the printer....

I was able to publish the MS-DOS partition of my Amiga hard disk and mount volumes from my brother's hard disk on his MacPlus. We had some problems with folders but I can think it was due to the older version of the Tops software we were using at the time. ------------------------------------------------------------------------------ In Real Life: Michael Nowak Workstation Consultant U of M Computing Center User Services Via Internet: mike@ninja.cc.umich.edu Via UUCP: uunet!umix!ninja.cc.umich.edu!mike Working for but in no way representing the University of Michigan. ------------------------------------------------------------------------------
