[comp.sys.apple] IIgs Memory Card

bird@cbnewsd.ATT.COM (j.l.walters) (08/23/89)

I have an Applied Engineering RAM Keeper, AE GS+ memory board,
and the Apple memory board that came with my IIgs. The Apple board
has 256K of soldered RAM and 256K of locally obtained RAM for a
total of 512K on the Apple board (The AE has 1 meg).

When I boot with the Apple card in the back pocket and the AE card in
the front I get a "ROK" message that tells me  that I don't have
either 512K or 1Meg on the Apple card.

I called AE and they said that the soldered chips (TMS 4256 - 15
NLA) were on their, "do not use list," and the locally obtained
chips were on their, "recommended list." The advised me to see my
Apple dealer.

My Apple dealer consulted AppleLink and it said that:
TMS 4256 - 15 NL were recommended, thus they didn't see where
Apple had a problem in this matter.

Now the question, is there a difference between:
TMS 4256 - 15 NL and TMS 4256 - 15 NLA chips?

If so, where can I get documentation that my dealer and Apple will
believe?

If not, what is the going rate for an Apple board with 512K that
works perfectly when not used in conjunction with the AE RAM keeper?

   One of those chips may be CAS/RAS type and the other not.  The IIGS
requires the CAS/RAS chips.

In reply to: j.l.walters re: Apple Memory Expansion Card problem chips...

According to "Open-Apple" (now A2-Central) August 1988, pp. 4.49-4.50, the 
questionable Apple IIGS Memory Expansion Cards with the questionable chips 
had the date code: 8751, 8752, or 8801 silkscreened on them and use chips 
manufactured by NEC in the UK.  Of Course, third party chips which are 
defective may produce problems... as I, unfortunately, discovered..

AE may have information not in the public domain.  I would suggest that you 
consider the utility: Apple GS Memory Test by Bob Consorti, ON-THREE, Inc., 
8920 Yolanda Ave, Northridge, CA 91324.  It will check the chips in your 
Apple Card, and pinpoint any problems.  As I recall, I d/l'd from CIS 
(ware).

Using the above... I discovered that my third party chips were _not_ CAS 
before RAS, and I had them replaced (with chips from AE) with gratifying 
results.  The AE RamKeeper utilities _failed_ to show the chip 
incompatibility with the Apple card.

The list price for the Apple IIGS Memory Expansion card (with 256Kb) is $189, 
as I recall.  The current price for each extra 256Kb is $69 or more...

If you are interested... I have upgraded my system, and I will sell 
(sacrifice) my Apple IIGS (1.0 Mb) Memory Expansion Card for $225.00.  Since 
I replaced the third party chips I have had NO problems, and will guarantee 
my card for 90 days (same as Apple).  My Apple card has been used for less 
than a year... but it is thoroughly tested... and it works perfectly.  If you 
would like to upgrade to true GS power at a bargain price (compare with 
magazine ads) let me know... (I'll provide a copy of the shareware Memory 
Test... if you desire).

My problem is fixed. One reader on the net sent me mail telling me
to look at the latest InCider for an article about problems that
Apple would fix. It mentioned the NEC chips you talk about, plus,
at the end it mentioned some unnamed chips with a little "A" in
the lower left hand corner. Armed with the article and my board, I
marched back to my dealer where they called Apple (Tech
support??). Apple didn't know anything about the little "A"
problem, just the NEC chips. However, my dealer decided to swap
boards with me so I could test my theory. I glad to report that
I'm now the proud owner of a 1.75 GS.

We hear a lot about bad dealers here so it seems only right to
sing out when there are superior dealers.

I not only agree, I think you should NAME names in these instances (else
how are nearby readers going to know who to go to)?
