Promising 80 MIPS by Feb. 1992 for $40 in (large volumes, I assume)? Sounds great, but it is just that -- a promise. Has intel ever made good on the promise that its i860 would run at 50MHz so that the 150 max MIPS figure hyped by the press could come to light? How fast does the chip run under normal conditions (i.e. with interrupt processing ON, using usual compiler output, using affordable (read slower) chips for memory)? Anyone want to take bets on whether intel's benchmarks had interrupts enabled, or ran the dhrystone benchmark from 80nsec memory? At least with a 68040, with its familiar instruction set, we know what kind of performance to expect by simply looking at the average number of instructions per cycle and the capacity of the cache. Other questions to be resolved: how efficiently would the processor emulate a 68000; is the microcode well geared to emulate its rich set of addressing modes and (small) irregularities? Would it have enough micromemory to do it? Can it address enough registers, or would it have to draft part of the cache for this role, inevitably slowing things down? How fast can it do a multiply or divide (it would have to do this very quickly in general purpose microcode to beat out an 040 with a built-in FPU with dedicated microcode)? We wouldn't know all of this until the machine and emulation software were implemented. That's a long way off. Also, a lot of fast cpus will be introduced in this year of 1991, so that 80 MIPS (whatever that means in real terms of performance) may not seem as fast by comparison in one year. And 1993? Well, in computer years, that's ages hence. By then, the 68050 may be a more familiar sight. It is difficult to speculate on numbers relating its performance with the information we have now, but...there was a recent announcement that Moto just built the largest, most dense chip yet (for the US Navy, too advanced for mortals like us to buy, with a good amount of space devoted just to nuclear-proofing redundancy), and one must begin to wonder what they're going to be able to do with their commercial products (that don't need to waste any space for redundancy) by 1993. >CISC emulation and multiprocessing capabilities. The pricing and performance >seem to be exceptional to me and are some of the qualities associated with >Clive Sinclair (and perhaps Atari), so that a Timex 200000K could soon be in >our hands? I'm all for power without price as much as the next guy, but my general feeling is that it's too soon to tell. As long as one can speculate all the way out to 1993, one can speculate about a lot of other things, many of them silly...like the Common Market banning American chips because the high frequencies might disrupt brain processes that control the ability of consumers to choose for themselves between labels stating "with hormones" or "without", or the Japanese opening their market to American rice due to a widespread boycott of Japanese submarine propellers :-P. When I see the TT040, or the PgC-ST at my dealer...or even at Toys-R-Us...I'll be convinced. Until then we can only make suggestions to Atari and hope that they'll listen. Right now we are having enough trouble getting them to put a 1.44 Meg drive into the TT...(by the way, TRH, your portable design is fine the way it is, IMHO). plin -- ----- ---- --- -- ------ ---- --- -- - - - plinio@seas.ucla.edu This page intentionally left blank so that it could contradict itself. ------------------------------ Date: 4 Apr 91 13:00:21 GMT From: noao!ncar!elroy.jpl.nasa.gov!usc!samsung!umich!vela!wsu-cs!jake!pbh@arizona.edu (Patrick Haggood) Subject: Cooling fan easy and it works! To: Info-Atari16@naucse.cse.nau.edu I just installed a Radio Shack muffin fan (part # 273-243B) on my hot ST and I can report that it works like a charm. I left the machine on all night and it's still blowing cool air. Installation was easy. I went for functional instead of pretty, so the fan is on top of the ST rather than inside. My ST would flake out after a couple of hours and the spot on top of the ST over the power supply would feel extremely hot. If I shut it down for 10 mins, it would work fine. I drilled two holes in the top of the ST over the power supply to screw the fan to the case. I drilled a third hole to run the wires through the top of the case. Then, I cut and soldered these wires: -----red wire ------ / -------- red wire --- ---------black wire --- disk drive fan power connector ------ blue wire --- / -------- black wire --- -------- black wire --- The ST has stayed cool all night and I'll bet this even makes her last longer. Highly recommended for Z-ram owners. This cost me about $15; you can probably find a 3in 12V DC fan cheaper at a real electronics store, but they're hard to find around here so Radio Shack had to do. -- Patrick B.

There is a good graphics card for 1040 from Matrix GmbH... If I remember correctly 800x600 with 256 colors on a 14"/16" multisync.

Requires Mac with super drive or a Spectre GCR 3.0 with Atari ST. I have a German HD-adapter on top of the WD-1772 02-02 floppy-controller chip. A small circuit board, that controls the clock-rate for the drive and some other things. Formatting and controlling software are included. This HD-drive does odd things in Spectre. It is not very reliable to use. If a floppy is reported bad in HD-drive, it still works in DD. (luckily I have two drives...) But it works great with Apple File Exchanger. Even 1.44Mb MS-DOS floppies are usable. But you can not use 1.44Mb Mac- floppies with it (at least format, I haven't tried reading already formatted one). The problem is the step-rate of the drive. If I could find a program that could adjust steprate in Spectre, it would be very nice. I have the HD-drive mainly for larger storage-capacity in ST-mode and for compatibility in AT-emulation.

To: Info-Atari16@naucse.cse.nau.edu It seemed reasonable to point out here that VGA uses a minimum of (I hope I have this right) 256 K of screen memory. I'm rather nearer to certain that most super VGA uses a Meg. This isn't the sort of thing that would have been considered reasonable when the ST was designed. Making the display system independent (ala PC) has the advantage of allowing you to make improvements when technology changes. It has the disadvantage of causing proliferation of semi-compatible 'standards'. (Look at the distribution kit of any high-end PC application. There are many screen drivers.)

To some degree this is a feature. Combined with the 70Hz refresh rate and 640x400 resolution the SM124 provides and incredibly solid display for doing serious work. It would be surprising if, say a 320x200 256 color GIF pic, was even recognizable on it, though. There simply are not enough pixels there to dither it properly. I have seen mono GIF viewers that get around this by displaying in a window which can be scrolled, thus allowing better dithering. You might want to look around for such a viewer. > Am I doing something wrong? Not really... but a color display is much much better for viewing GIF pics, even mono GIF pics (see below). > 2) Does the STE have gray scales, you know, proper shades of gray, not > just the nearness of black and white pixels?

Someone else answered your question 'no'. IMHO, this is complete BS. Below is how I typically view GIF pics, usually 320x200 256color images. Many times you can view these with no loss in resolution or clarity: 1. Get GIF pic. 2. Convert to Spectrum 512 format using GIFSPC (<-- available at an archive near you) 3. View the Spectrum pic. (<-- viewers also available at archives) Since you're new to the ST series, I'll tell you what Spectrum 512 format is in case you haven't heard of it: Spectrum 512 picture format uses some software trickery to display more than the maximum 16 colors in 320x200 color mode. It changes the color palette on a per scan line basis with a maximum of three changes per line thus, you can have up to 48 different colors per scan line. This allows creation of pictures which display the entire 512 color palette of the ST on screen simultaneously. I don't know if the extended 4096 colors of the STe are supported but you still shouldn't have any problems using 512 colors. If you try to to view incredibly hi-res pics (ie. 1024x1024 at 16Million colors) they still won't look all that great. GIFSPC can scale the resolution down, however... I have some 640x400 many color pics which look very nice on my ST when converted to Spectrum. -- /**************************************************************************/ /* Kent Dalton * EMail: Kent.Dalton@FtCollins.NCR.COM */ /* NCR Microelectronics * CIS: 72320,3306 */ /* 2001 Danfield Ct.

Well in fact there seem to be three (two on the ST?) active shell levels above the current program while you are in the auto folder. If I set those they are not propagated to the GEM desktop (TOS 1.4 or 3.01), which has two levels of it's own. In fact the environment for the two desktop levels is changed to contain only PATH=\0. When I change the desktop p_env's gulam notices the changed external environment, but shel_find (and thus rsc_load) stil doesn't. Am I still doing something wrong? I reread the readme file that goes with environ.prg. In this readme it is stated that source should be included. But I didn't find it in the archive (from some local BBS I think), does someone have this source. I also would like to know who the author is. > Of course, you could always get NeoDesk, since it replaces shel_find and > avoids this whole mess in the first place .
