My Emax shows 10512… as the total memory available…
What i dont understand is why my output board doesnt have stereo already installed as its a 2212 model…
The guy who sold it to me, might have replaced/removed the chips in fact, or swap the output board of the 2megs Stereo Emax with an output board of a 1meg Mono Emax (which i think could be the stuff).i think it could be wiser to negociate a return with paypal case instead of running around
trying to a get all those, when they should have been installed already…
and maybe wait to find a more "recent" model fully equipped.
If someone here wants to get rid of an Emax II rack or Keyb Stereo with 8Megs, direct message me: lifelike@...
Thanks

Sorry, but I don't think that's how it works.If there is someone with more expertise, please correct me….but this is my understandingAn Emax 2 either has 1 MB or 2MB on the main board.Where 1 MB you use one set of addressable RAM chips, for 2MB you use the other set (not populated in this case - I believe this board has 1MB and can be checked using "Free Memory" menu option).You have to have the correct support chips in addition to properly address the specific set of chips in use.Unless you have the correct PALs, then you cannot just put in more chips to make 2MB.If you have the correct PALs, you could make it 2MB with the correct chips populating the empty spaces- but it holds 2MB and no more on the main board.In addition, when you add the RAM expansion board, a 1MB on the main board maxes at 7MB (again with the correct PAL chips and enable code), 2MB can get the 8MB.This is enabled or prevented by the installed PAL (locking) chip set and the unlock code / update disk that installs the code (one use disk) to update parameters in the eeeprom.More about the correct PAL combinations and memory chip locations is in the memory upgrade guide for the expansion board (available on the web).Please note - you can't just "copy" PALs- they are fused to prevent reading out the locking algorithm.There have been efforts to break PALs by the Arcade Emulation teams even by making special cracking boards and software modules.PAL "L" series have been broken, and can be read out.Last word was that PALs that are "R" (R = registered PAL16R4ACN) like Emax uses are STILL not broken, to this day.The only reason I have the Emax 1 SCSI TIM PAL (which allows the SCSI enable features), is I was given the original factory binary by Rob at Emulator Archvie.It was proprietary format and did not work "as is"…. I had to research and work through process to get it converted to a format for use with my programmer.Please note that programming a PAL requires an expensive programmer.A $25 or even $200 IC / EPROM programmer won't program them. You need a DATAMAN 48 ($1200) or similar to program them. The cheapest programmer I have seen that *MAY* program them is $800…While that may not be what you want to hear- it is better to know truth, then to make many attempts wasting time and $$$$ trying to get something to work that cannot be made to work.Regards,TedOn Jun 7, 2014, at 1:37 AM, - LIFELIKE - lifelike@...

so if you have 2 already installed you should be able to make it 6mb
