The old machine runs

I got the TRS-80 model II running about as well as a model II ever did. I replaced the disk drive mechanism, swapping the electronics in the process, so the replacement drive went in with the original drive's electronics, thus making one good drive out of one bad and one flaky one. When I did that, the machine came up, but the display's left side was wrapping around. A bit of tweaking on the monitor's horizontal hold control fixed that.

By request, here are some pictures...

Front view, with the power off:

Front view, running CP/M. The display's a bit hard to read, but it's a directory listing of the contents of the A: disk:
Front view, power on

The innards. The disk drive is on the far left; the card cage is in the middle, with, left to right, video/keyboard, memory, floppy controller, and CPU cards; the monitor is to its right; and the power supply is on the far right.
