[comp.sys.apple2] ZipGS GX

dcw@goldilocks.lcs.mit.edu (12/05/90)

I just got my Zip Chip GSX yesterday and after having a hell of a time
trying to pull my 65816 out, got it installed.

I don't work right! In fact, it doesn't like my hard disk (80mb
Quantum 32, 32, 16 connected to Rev C SCSI).  I have to have the
machine running at "normal" speed (Zip is off) for it to boot or
access the HD at all.  If I boot 5.0.3 off floppy, it crashes as soon
as it locates the HD.

It doesn't matter what speed setting I have the Zip at, so I figure
I've got bad cache ram. Has anyone else had such problems? I'm calling
tech support when I get home later.

I also had it destroy the appledisk3.5 driver on my LOCKED system
5.0.3 floppy. It also didn't boot 100% reliably from floppy or HD when
in slow (off) mode.

system: 3mb AE GSRam+ in ROM 01, Rev C SCSI, system 5.0.3, 80mb Quantum.

I got my GSX a couple of days ago and it works GREAT!

My setup is ROM 01, 4MB of RAM, RAMFast SCSI, 80MB (Seagate), and GSX.  I
haven't encountered any problems that I haven't had before, or isolate to some
DA or INIT file.  I have the GSX 1.01, but the manual says version 1.02.

I'm using System 5.0.3 and also have used 5.0.2.

I can't think of what to recommend... but I've heard some people have problems
with GSX... actually, it was one person who sent me mail on AO... you're the
only second person to have any problem far as I know.

What slot do you have the GSZ in?  I have mine in Slot 3.

Hi,


	I called Zip, and they say that the ZipGSX should work OK with
my setup. I can boot with no problems from floppy (3.5"), but if I try to
access the HD from the boot, it either hangs or crashes.

	I called Roger Coats again yesterday, and the person who authorizes
the RMA's was not in. I think that requiring multiple long distance calls to
complete a transation stinks. I had to do this once already when they sent
me a regular ZipChip on my first order. I have two long distance calls, and
about $5 postage & insurance invested if rectifying this situation, and so
far zip (OK, it's a pun).

	I left work early again to call Roger Coats today, and no one answered
the phone. So far, I can say from direct experience, that RC's service is fast.
But if something goes wrong, you will solve it at your own expense. And this
is not an easy proposition. There seems to be no guarentee that the person you
need to talk too will be in. And of course, when I do, I will have to explain
the entire situation again.

	Zip's spokesman was very verbose, and hardly let me talk. It was
mostly a prepared speech. I found out that if you upgrade the SRAM, then your
warranty is null and void. He seemed to think that most people who upgraded
their systems were somehow smart enough to pull the CPU (with extensive
handholding), but nowhere near smart enough to replace the SRAM chips. He
did not say this directly, and I never got a chance to make the comparison.

	So far, my experience has been very frustrating, and it is getting more
and more expensive day by day.

I've talked to the zip guys (luckily for me they are within driving distance)
on the phone (I haven't managed to get a ride over to swap my board for the
RAMFast fix version yet). I have found them to be fairly nice but they got
really awkward after I asked them a technical question -- until I told them
to explain as techie as they wanted.

Most people ARE smart enough to pull the CPU. Selecting SRAMs of the correct
size and pinout for upgrades is not something I would want to try unless I
knew more about which chips the Zip was designed for. Since Zip hasn't released
this info, they are fully justified in discouraging people from risking their
accelerators. The main reason I agree with this policy is that Zip is moving
to a cache RAM combination that uses faster chips for tag (I assume in
preparation for the ASIC 65816) -- chips which are NOT widely available to
consumers. Looking at my Zip GSX, it has two skinny 25 ns tag RAM's -- don't
count on JameCo carrying these.

I found the Zip tech support guys to be pretty good.  I was missing a page
of my manual, and they faxed right out to me the newest copy of their manual.
One of the guys I spoke to, I believe his name was Steve, answered all of my
questions, and gave me a lot of information.  I asked him about upgrading
the SRAM, and he said that they don't consider it a user-upgradeable option
anymore, and that they recommend you send it in for the upgrade.  Apparently
a number of their beta testers (people who should have been technically
competent to do it) had a lot of trouble installing the cache ram properly.
But, he said if I wanted to do it myself, he'd tell me how.  

Basically, you need to get 32k x 8 static ram chips (Microprocessors
Unlimited sells them pretty reasonably - check the classifieds in the
back of a PC Week).  You need 2 chips (one for tag ram & one for data
ram) for 32k, and 4 chips for 64k.  The important thing is that the
tag ram must be faster than the data ram.  To run at 8MHz, you need
tag ram at 70ns and data ram at 100ns.  If you plan on upgrading the
Zip CPU to a faster one, then you need a 25/45 ns ram combination.  This
is what Zip will install (the faster ram) for the upgrade for $75/32k.
Microprocessors Unlimited sells these chips for $25 and $19.50 each for
the 25 and 45 Mhz chips respectively.  If you don't plan on going beyond
the 8Mhz CPU in the near future, you can purchase 70 and 100 ns chips for
$10.50 and $6.50 each respectively.

The guy I talked to said that going from 16k to 64k of cache ram will
make a noticeable difference in speed (more than upgrading from an 8Mhz
to a 10Mhz cpu) as the CPU won't need to slow down as often to regular
system speed to access standard IIGS memory.  I plan on purchasing the
70/100ns chips for now because they're not that expensive and when
faster 65816s become more readily available, I'll buy the faster ram
chips then.

Gee Todd, I asked them about SRAM speed, and got the propaganda speech about
idiots putting chips in backwards. Never was access speed mentioned, even thoug
h
this was my question. I got the feeling that he thought I had something to 
destroy my ZipChip GSX, and he referred me back to Roger Coats. Guess what,
I got off work early again today to call RC. They do not answer their phone.

Since warranty's are somewhat time dependant, I am beginning to get concerned.
Three days of effort, and nothing. Did RC close for the holidays? Did they
change their hours? If not, I will have to attempt to get in some words with 
that chatterbox from Zip.

I work with CMOS all day, every day, and can give lectures on static hazards,
and proper grounding. I do not revert to a caveman (static filled) the moment
I get home. I have taked much better than reasonable precautions, after all, 
this is ***my*** stuff.

Like I said, if it works, great. If it don't, expect your cost's to double,
wether or not anything happens, at least if you order from Roger Coats. I have
gone to a great deal of trouble, and not inconsiderable expense, with nothing
at all to show for it.

And there is an irregularity on my Zip. It came with a score mark on the front.
I have no idea how it could be done, but it seemed only to affect the breadboar
d
area for the voltage regulator. Perhaps it goes farther than the eye can see.

To everyone who's Zip works, congratulations. To everyone considering purchacin
g
one, be advised. At least if you own a RAMFAST, or intend to buy one...

You're talking to the wrong people at Zip. Ask to talk to one of the techies
or something -- I don't know, I just called their tech support number and got
a reasonable engineer after nominal time on hold.

This sounds very simular to my situation.  I pulled everything out of
my computer except the Zip Chip and RamFast.  Trying to boot the hard
drive always resulted in a freeze or crash.

When I called Zip and explained my situation with 2 Zip Chips and my
setup, he seemed very willing to help.  They are sending me a new (and
modified Zip Chip) while I mail my current one to them.  They think my
problem is because of noise and the replacement chip will be more
tolerant of it.

I'm frustrated in not having a working chip, but the calls I made to
Zip and Programs Plus have all been helpful.  This is taking awhile, I
hope it's all worth it.

Those who already have Zip Chips and are worried about the cable connection
to the CPU socket coming loose.  Go to Radio Shack and buy a $1 40 pin
low-profile chip socket.  This fits real well into the CPU socket and the
Zip cable is almost unseperatable after plugging it in.

Gee... To show the other side of the coin now:

I have had my grubby hands on TWO Zip GSX's. (Same revision; v1.01). I've also
had my hands on two RAMFast's... One is serial # 64, the other is # 967 (or
something close). The newer RAMFast is running ROM v1.11, the older one v1.01
or v1.0.

I have used BOTH of them in a ROM01 and ROM03.. never any problems. Except
during a GS/OS copying of a file, where it will bonk into the monitor and
require a power off/power on combo to get the machine back. The TWGS used to
cause the same weird problem as well.

There have been MANY people who have used the Zip GSX and RAMFast in tandem
with no problems.. Me being one, and counted as two.

What is your point, are you saying that mine works? You may add input, and 
let everyone know that you are another satisfied user, but how can you imply
that they ***all*** work. Let me also add that I have been attempting to 
contact Roger Coats for 2 WEEKS, with no success. I am not a happy camper.
And my Zip does not crash when using a program, I have not gotten that far, it
crashed while booting GS/OS. It boots and runs without error from floppy, but
the moment I attempt to access something on my HD, I get a crash to monitor.
It is a certain, long tested compatibility issue, despite the fact that Zip
claims that it should work. They referred my to my Dealer, Roger Coats, whom
I cannot contact. You may be happy, but I am not. You would be stupid to be
happy under such circumstances. I have given a valid trouble report, not
out of malice, and stated the circumstances and facts. I think your comments
add nothing, and inply that I do not really have a problem. But I will not
go as far as to suggest what you do with the "other side of the coin". 
Ten million functional Zips would change things not one bit.
