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).
