PIP problem solved on Apple ][ CP/M

I was finally able to devote some time to my Apple CP/M issues and figured it out. It turns out that the version of MS CP/M that I'm using has got the device identifiers correct, even though Steve Hirsch warned that they were reversed in Microsoft's implementation. I apparently have a version where it is fixed. I first connected up my laptop to the Super Serial Card in slot #2 and then tried to PIP RDR:=B:file. I got a message to the effect that the RDR: device cannot be written to. Then I tried to get slick and use STAT to change the RDR: device to what PUN: was pointed to. That didn't work. Then I decided to just try PIPing to the PUN: device and it took, but I didn't see anything across the serial port. A little more digging and reading and I verified that, as Steve said, the Apple ][ CP/M standard is for a serial card in slot 2. In fact, the documentation I read indicated that the hardware configuration pretty much matches that of Apple Pascal. So I did a STAT DEV: to show me what devices were connected where. RDR: was set to PTR: and PUN: was set to :PTP (presumably Paper Tape Reader and Paper Tape Punch respectively). So then I did a STAT VAL: to see what the possible connections were for each device. PUN: could be TTY: PTP: UP1: UP2: I thought for a second and then figured it would be worth a try to see if UP2: stood for the device in slot 2. Sure enough it did, and when I tried a PIP to PUN: it worked.

So I was able to PIP the files directly from disk over the serial port to my laptop. Very convenient.

There apparently is a utility that allows you to copy files from CP/M disks to Apple DOS disks but it must have come on a DOS utility disk that I just don't have.
