Restoration of a Lisa 1

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

Ah, there is that. I have a ton of CF cards so I don't bother with multiple images on one card. Just a straight dd off the card and back onto another works with me without issues.

Lisa Office 2.0 won't work with the Lisa 1. Here is an excerpt of a document I have:
CONVERSION TO THE LISA 2
By the time this is published most owners of the original Lisa will have converted to the Lisa
2. There are three parts to the conversion process: getting all you files ready to be
converted, making the actual hardware modifications, and updating to the new system
software.
The most troublesome (and potentially risky) part of the conversion is getting all your files
on the Profile drive before converting the hardware. This is necessary because the new
system does not have any software drivers for the old 51/4-inch disks drives. If you convert
and then find some files you forgot, there is no easy way to recover them. For everyone
except developers the hardware conversion is done by a dealer. (Developers are given the
kit to make the conversion themselves.) It involves swapping the old 51/4-inch Apple
drives for the new 31/2-inch Sony drive, swapping some integrated-circuit chips, and
cutting one or two resistors off a board. In my case, the conversion went very smoothly.
The last step is to update the Profile drive with the new system software. All Lisa 2
conversion kits contain release 2.0 of the Lisa software system, which involve modifications
down at the disk-directory level. When you update the drive, all the file-formatting changes
are made at the same time, although users are not really aware that this is happening.
Once you have converted, you are unable to do a disk-to-disk; you must go through the
Profile drive as an intermediate step

Figured I would post this here for my Lisa.
My Lisa has a weird date code and an early serial number. Since it doesn't have a serial number tag, I had to get it from Service mode. Someone has told me it may be a pre-production model but if not, it is definitely early.
240: FF 02 82 020 0166 0 FF
Plant=02 YY = 82 DDD = 020 Serial = 0166
250: 0010017504100000
AppleNET Prefix=001 Number=00175
Update: I have BLU on a CF card for Blu so I am just working on making a 3d printed template for Twiggy floppies now.

Well, I am getting there.
I went through five Profiles. Two just shut down and stopped powering up (will have to look at those), one had RIFA fireworks and a smoke show, one just wouldn't complete a low-level-format with BLU and finally got one working.
I went through four keyboards. Two were refoamed and I still don't have a properly closed working keyboard. For now I just use my finger on the PCB. That will need some attention.
I went through several IO, CPU and memory boards along with card ages and parallel cards. I thought my Serial B was not working but it turned out to be my serial cable. Went through two serial cables and three gender changers to mate with the Serial B port.
Anyway, I now have a working booting LISA 1.0 system thanks to @stepleton and his BLU Profile image. Thank you! Sadly, I can't run any application because it is "not licensed" for my computer but I can deal with that later. Picture attached.
My next adventure if is to test the Twiggy drives and I am in the process of 3D printing a template to make some floppies. Once I have some floppies, I'll see what happens with the drives and I'll see if I can create Lisa OS 1.0 Twiggy floppies to try to do an installation (if I ever get that far). Frustrating but will definitely pay off if I can get her going properly.
Thanks for the help and encouragement so far.
stepleton:
Congratulations!
As a check, just after booting, do you hear the Twiggy drives "grunt" as they activate the ejection mechanism in either drive? At least, this is what happens on my Lisa 1. The ejection mechanism is also activated when I shut the Lisa back down.
