Restoration of a Lisa 1
rayarachelian:
Stare upon the eviiiil capacitor that Tom turned into a t-shirt. (and yes, I do want one!)

Well, it seems I can't get my Lisa serial port 2 to work so I can transfer the LOS 1.0 image to my X/Profile via BLU. I will have to try another motherboard/card set tomorrow. Gotta take apart another Lisa 2 for this. Onward and upward tomorrow.

If it's not one thing, it's another!
This might be easier: run BLU on one of your Lisa 2s and use that to do all of the hard drive image management. Then just move the hard drive (or X/ProFile) back and forth between the "BLU computer" and the Lisa 1.
I also had a problem on my Lisa 2/10 where serial port 2 stopped working. The good people of LisaList helped me find the chip on the I/O board that went bad, and ever since the replacement things have been fine. Something to fix for later :)

For what it's worth, if you have a machine running Linux or macOS and a CF reader, you can also make backup copies by using dd. Probably much less hassle to dd to a disk image over USB than it is to wait for a serial connection to go through.
I feel you on the Rifa caps - I had both my Mac 128 and 512ke going once and both Rifas blew together. That was not fun.
stepleton:
The problem there is that it may be a delicate operation to put the disk image into the right place on your X/ProFile CF card without disturbing the other disk images it holds.
Additionally, I think the "raw" format of X/ProFile data may differ somewhat substantially to the format of BLU disk images. I'm hazy on the details---basing what I say here on a browse through the X/ProFile manual quite a while ago. I seem to remember that there are several possible image formats called STARs, each optimised for different kinds of underlying media, including IDE hard drives and so forth. These formats organise the data in different ways, partly to accommodate the fact that ProFile blocks are 532 bytes, not 512 bytes.
If you do decide to explore this route, in any case, I think you will need to remove the first 532-byte block from my Lisa 1 BLU disk image in order to obtain a "raw" image file suitable for use with dd.
There is at least one ProFile emulator out there that uses contiguous, raw disk image files on an ordinary FAT filesystem---but it's not very popular, was made by an amateur, and requires a bit of fine surface-mount soldering ;D
