[comp.sys.amiga] A2620

870646c@aucs.UUCP (Barry Comer) (04/20/89)

I had the chance to HOG a 2500 yesterday at a local dealer, it gave me a
chance to load Lattice onto the hard disk and try things out. I must say 
that for most programs I was not very impressed??????
I am taking it for granted that this is because of kickstart being in
a 16 bit ROM, I called CSA and they say that their Drag Strip option on their
68020 board includes a 32 bit ROM version of Kickstart which makes a major 
difference(if anyone can back this up let me know). I now have a copy of 
SetCPU that is spose to more or less do the same thing(in this case it copies
Kickstart into 32-bit RAM). The big question is "Has anyone tried this 
program, and if so how big of a difference does it make?"

I must say that it is kinda nerve racking to see all these complaints about
the A2620 board. I have had one for about 1.5 monthes and am completely
happy with it, it blows the old stock Amiga away(it better for the price).
Are there any other people out there that are happy with there investment
or am I the only one.

P,S. Who was that fello that got 5000 drystones out of one of these anyways
     and how did he do it(I think someone had too much to drink one night.
     Using the Drystone.c file from one of the first Fish disks and compiling
     with Lattice 5.02 using: lc -m2 -v -L , I get about 3000 drystones, this
     goes up to about 3450 drystones when using the -O option. If someone
     has another copy of the drystone or any other normal benchmark could you
     pass it on. Thanx

I get 5000 drystones consistently doing the following:

1) define all prototypes
2) lc -v -w -cf -L -m2 -O -rr drystone
3) modify the linker file to include lcsr.lib and lcs.lib so time()
   will work.
4) relink it.
5) changetaskpri to 100 and run it!  5000 drystones.

I've had my 2500 since early March, and I am more than just happy, I'm
ecstatic (sp?).  I use a 'PC' at work, with 4 megs of RAM, 386/387 combo,
and MS-DOS 4.0 (I tried OS/2, bleccchhh!), and I can never wait to  get home
to Ami.  I've run the mandelbrot generator (written specifically for a
386), and it doesn't come close to the versions written for a 68020.

And none of the operating systems I've tried can come close to the
way Ami multitasks, with the possible exception of UNIX, which I
hope to get for Ami someday, anyway.

Consider me a VERY satisfied 2500 owner.

That's all well and good.  I too, love my Amiga - when it works.
Since installation of the 2620 board in my system, I continue to
experience a lot of random crashes.  What I'm trying to do is find out
what is wrong.  It's great to run about three times as fast as the
68000, but if I have to reboot every 30 minutes it doesn't do a lot of
good.

This weekend I experienced the following:

	4 Gurus while running Lattice 5.02 (could be the compiler,
	since most unexplained crashes are during heavy compiler
	activity)

	3 Instances of machine lockup - no action

	2 times we just went right to the reboot, no guru.

	2 instances of screen corruption

	1 instance of what I call the ammusement park syndrome -
	everything goes off at once - DF2: was a hopping and a
	twisting, the printer was printing out garbage, the screen was
	corrupt, and the select lights on both a hard drive and DF0:
	were locked on.

All of the above occurred while multitasking and running Lattice
compilations with different disk, include, and source locations (ram
or disk) and nofastrom.  With fastrom set, I have observed none of
these failures.

Additionally, with or without fastrom and the compiler benchmarks
running, I get occassions when a single key is repeated 10's to
hundreds of times and then a long time goes by before I can delete the
garbage and retype the command line.

I have observed none of these problems when booted from the 68000, but
the loss of 2 meg and 3x performance makes this an undesired
configuration, so I spend little time there.

The purpose of posting this to the net is not to discourage people
from owning Amigas, although I realize that that may happen.  I really
just want to get a reliable system and peolpe on the net are helpful.

Thanks to Mr. Hull for sending me the memory tests.  I have run them and am
unable to get any errors from the memory card or the slow-fast ram.

I have also written a checksumming program to ensure that the ROM
always responds correctly.  So far no errors have shown up.  This is
really a mystery, and probably concerns two or more distinct problems.
I like to do work on the Amiga, but the platform must be reliable.

Thanks to all of you who make the amiga better all the time,
Mark Huth
