From: Mike Ciaraldi <ciaraldi@Rochester.ARPA> I was recently faced with transferring between an SD system and an Eagle II. The SD had MODEM7 running, and had an 8-inch floppy, but the Eagle had only 5-inch, with no documentation on the format. fortunately, both had serial ports, which were configured into CP/M as RDR: and PUN: So, we wired the two ports together, and used PIP to transfer source from one machine to the other. On one, I PIP'd to the PUN:, and on the other I PIP'd from the RDR: into a file. We had to do it slow, because there was no error-checking, but we got the source for MODEM7 across. At that point we realized we did not have a macro assembler on the Eagle. The serial port driver strips off the high-order bit, so we could not transfer the assembler, plus it is somewhat complex to trust to a trasnfer without error-checking. So, we modified it in the SD to match the Eagle hardware, assembled it, and PIP'd the hex over to the Eagle. There is an option on PIP to check for valid Intel hex format. It seems to discard all improper records without any message. But comparing file lengths told us the transfer went OK. Anyway, we now had MODEM7 for the Eagle, and started using that for subsequent transfers. I would also suggest a local Apple, DEC, or CP/M user group for the possibility of MODEM7 already ported to the right format.
