As far as I know interleaved memory is not standard on 780's. (At least it was an upgrade for us.) Both vms and 4.2 unix require the same change to the boot floppy to handle interleaved memory. The following four lines must be added after the line with INIT and before the line LOAD BOOT in defboo.cmd DEPOSIT 20002000 101 ! SET UP INTERLEAVED MEMORY\015 DEPOSIT 20002004 4000 DEPOSIT 20004000 101 DEPOSIT 20004004 4000 This correctly configures two memory controllers for interleaved operation. I suspect the procedure is similar if you have more than two. Russell Yount cadre!ry

If you have the old MS780-C memory, then a single controller does no interleaving. If you have two of these controllers, you must add several "DEPOSIT" commands to the defboo.cmd command file on the floppy to set the "interleave" bits in the controllers before loading UNIX. If you have the newer MS780-E memory, then a single memory box actually has a pair of controllers which are normally interleaved; you don't need to do anything to turn it on, and thus can use the defboo.cmd unmodified.
