The PDP-1 Handbook says rim will load into whatever bank is set in the extended addr switches when ext is on, but it doesn't seem to do so, the code always ends up in bank 0.
Anyone have any input?

Getting crickets here, I ended up adding code to my bank 0 program to copy the parts I wanted in bank 1 there after loading. Still can't figure out how to use readin to load into another bank.

Hm...without testing (sorry, just trying to quickly reply to a lot of threads) it looks like the emulator *should* do the right thing, however it may be that you're trying to load a tape with a BIN loader? that will not work (i support extended mode loading in my monas assembler). but i can check it out myself later

Ah, that's the issue. Binloader. So, I could assemble with -r to get a pure rim tape and that should work? Sigh, jumped thru hoops to load into bank 0 and then relocate the code to bank 1.

No joy. I assembled a test with macro1 -r, verified by disassembling that it has no binloader, just the straight code. I turned on extend, set the extended bank to 1. Examined a loc, addr lights show proper address. Did a readin, extend goes off, tape loads in bank 0. Examined bank 1, no code loaded there. Guess I'll have to stick with crafting code that I copy to bank 1. Or, maybe the new macro and loader that work with extended memory? Is that released yet?

I found an oversight in my code, oops. Should work now, please test.

Will do, stay tuned.

That fixed it, readin now loads to the specified bank!
Thanks, Bill
