FastlaneZ3 Modification for 256mb RAM

[amigadave]

Well, my FastlaneZ3 did not sell on eBay for the second attempt, so I might keep it and use it in my A4000, or A3000T.  When I bought it, the seller told me that it had the latest ROM update.  Has anyone here done the modification that allows the FastlaneZ3 to hold 256mb of RAM?

If I am going to keep and use it, I want to upgrade the 40mb of RAM that is currently installed on it to the maximum 256mb of Fast RAM.  That could give me a total of 400mb of Fast RAM & 2mb Chip RAM on my A4000 w/CSPPC card and might make for some interesting tests of running Lightwave3D and running large animations, or short Flyer videos from RAM, instead of from a hard drive (if Flyer video could even be run from RAM instead of across the Flyer SCSI-2 bus?).

Anyway, I would be interested in hearing from anyone who has had a FastlaneZ3 card with 256mb of RAM installed on it.

Thanks for the replies.  I could not find the revision number on the FastlaneZ3 board itself.  Can you tell the revision from the serial number?  It is 3100570.

My board came to me with a square chip in an envelope, which is an upgrade that I thought would allow the use of the 16mb simm's.  The identification on the top of this chip is:

AM27C1024
-120JC
9708MPM
12.75V PGM

Is this an upgraded ROM, EPROM, or something else?  It was sent to the previous owner from someone else as an upgrade, so I am guessing it might be the upgraded z3scsi.device.

Who still knows how to upgrade this card to use 16mb simm's and what would you charge me to send the required upgrades?

Thanks Tim,

You didn't really expect me to remember everything you told me when you sold it to me, did you? That was like 3 years ago. :-)
