Well, minimally I'd like to get DOS running, and the ADTPro documentation says that can happen with only 48K, but it's not working for me - transfer seems Ok, so I do believe it is a memory limitation. (ADTPro calls this 'EsDOS][' - anyone know what the Es stands for? ) I found two different types of RAM in my machine - both are MOSTEK: MK4116J-3 IRL and MK4116N-3GP. I couldn't figure out the difference between 'J' and 'N'. The specs seem to show that '3' is for 200ns (oddly enough). I've ordered another 3GP, as those are the types in the bank missing the chip. And, I'm on the lookout for a language card. Thanks again

Super helpful. Thanks much MarkO (and Keatah)

Hi all - I just purchased an Apple II+ and it has no language card. I know the stock II+ has 48K, but the RAM chip where you would normally connect the language card (top left if looking down on the mobo) is missing. Does this mean I only have 46K? Is there a way I can verify how much RAM is on my II+ ? I ultimately want to use ADTPro to load DOS, but I'm worried that this missing RAM chip may prevent me from doing that, or generally have some other problems. Thanks, Chris
