Using two RL02 drives on OS/8? (cont'd)

It's working again! I made a new RL02 pack using vtserver on my other machine (11/23+), which takes a while to transmit 7.8 MB even at 19200 baud, put it in the 8/A drive 0, held my breath, flipped the boot switch... and got the "." prompt on the terminal :) So the problem that started this whole mess was an IDC connector that I had improperly crimped, inside one of the RL02 drives, so that I could run ribbon cable to the RL8A instead of buying the expensive BC80xx cable. Lesson learned. Bought a BC80J-20! That short circuit was somewhere in the write data lines, which apparently then wiped out the OS/8 pack so it wouldn't boot any more. Lastly, my incorrectly seated quad extender card was introducing errors even after fixing the cable problems, and I wasted several hours chasing that... I may invest in a hex-height extender card to avoid this problem in the future! On the other hand, I now have a serial interface on the desktop PC is to learn how to use Philipp Hachtmann's KL8E in FPGA to download through a laptop USB port at high speed. It looks like I can just change the few IOT instructions of the RIM and BIN loaders to match the card's switch settings. Trying to get Windows to put binary files out a USB port will be more fun, I'm sure. Meanwhile, back to the original problem! My build of OS/8 does not recognize that there are two RL02 drives in the system... which is how I think this thread got started in the first place quite some time ago :)
