Well, if there is usable RAM above 650k, you may be able to get some working UMBs. There are options to disable and enable various features for JEMM as well as force it to include or exclude different memory regions. Unfortunately, that is all very machine specific and I really cannot help you out with trying to get that working. There may be some very useful information to that end in the documentation for JEMM. If you are able to create a working configuration to provide UMBs for PocketDOS, please share that back to this list so others can benefit from it as well. :-) Jerome
