| 634.1 | Faster Graphics? | SSDEVO::YESSE | Computing at 6200 ft. | Wed Aug 05 1987 12:57 | 8 |
| Seeing this, & the note on Siggraph...can the 68020/68881
effectively speed up realtime animation? Or are you limited
more by the fixed size of chip memory or other architectural
restriction?
This comes from a soon-to-be Amiga owner interested in
very fast frame computation...

I've seen the bouncing ball demo running on a CSA turbo-charged
Amiga, and it moves so fast you can't follow it ! The
issue really is whether the graphics generation is compute-bound
or not. If you were just popping up IFF images or something, the
difference might not be so noticeable.

| 634.3 | Hey, I know where that is!!!!!! | DDMAIL::ANDREWS | Just living a life of illusion | Wed Aug 05 1987 18:29 | 7 |
| Being as Buffalo Grove and Arlington Heights (where I work) are
right next to each other, I'll call them for you. However, you
must give me a list of questions that you want me to ask. I don't
know what sort of information ou want to know, and I can't see myself
calling and asking really stupid questions.

| 634.4 | questions for Motorola Amigans | NAC::VISSER | | Thu Aug 06 1987 11:32 | 14 |
| re.: .3
Rob,
I'd be interested in the following:
Are pc boards available, bare, socketed, or otherwise?
Are shematics available?
I guess the comprehensive question is, Is the design documentation
available? This would typically include schematics, PAL equations,
parts list, PCB artwork, debug notes, etc. From this database one
could replicate the board; indeed the package might be uploadable.
A good format for the PCB artwork might be an HPGL plot file, or
a Gerber photoplot file; schematics in IFF, Aegis Draw, etc.
Thanks, John

| 634.5 | more info | LEDS::ACCIARDI | | Sat Aug 15 1987 02:55 | 35 |
| Got a bit more info on this 68020 doohickey...
The guys are making a production run of boards. They have, until
now, made them of a onsie-twosie basis.
Prices are as follows:
Fully loaded board w/68020 & 68881 $775
Board w/68020 only $550
Board w/o either chip $335
The board plugs into the 68000 socket via cable (surprise) but I still don't
know if it is an internal mod or if you must run a cable from a
Zorro slot INTO the 68000 socket. Still don't know about schematics,
misc widgets, etc. I also wonder if the board would interfere with
Insider-type boards or not. The contact there is now Reno Pittner.
I got this info off of Plink, where it seems to be generating mucho
interest. If this is a reality, it could be a real cheap way to
transform the humble Amiga into a real workstation. Imagine the
following:
Refurbed Amiga 1000 $450
external floppy $200
Sony monitor $500
20 meg SCSI drive $750
68020/68881 upgrade $775
----
total $2600
That's got to be the best deal on the planet, no matter how you look
at it.

| I'll believe it when I see one installed and running in someones
machine. (P.S. I believe it is an "insider" type board)

| 634.7 | I saw and I believe | WINERY::COLLUM | | Mon Aug 17 1987 11:44 | 11 |
| HT Electronics (Sunnyvale, CA) has an Amiga 500 with a 68020/68881
board internal. The sales rep at the time said it fit in the 68000
cpu socket (i'm going back when someone technical is there). He
also said that it was NOT Amiga 1000 compatible. What would there
be about the 500 architecture that would allow this while not on
the 1000? The board was $800 list price. There was a noticeable
difference in speed.

| 634.8 | Whats so hard to believe? | LEDS::ACCIARDI | | Mon Aug 17 1987 14:14 | 9 |
| Re: .6
Boy, are you a skeptic Paul. What's so hard to believe about running
a 68020/68881 inside of a 1000? Aegis Development claims they have
several development A1000s all running the Gemstone board (it's
actually called Sapphire). Unless they have a prior record of outright
lies, I see no reason not to believe them.

68881, 4 control chips, adapter plug going to Amiga 68000 socket.
No ribbon cable visible. Dimensions about 4 x 5 in. ]
68020/68000 benchmark tests show up to a 40% speed improvement.
Use of the 68881 floating point coprocessor can improve floating
point performance by a factor of 10 or more. 68020 and 68881 locations
are socketed for ease of installation.

[Comment: Wholesale price is about 75% of retail. Somebody (not
me) might consider organizing a group purchase. The flyer makes
no mention of software. What compilers are out there to generate
68881 instructions?]
