are there any plans/ schematics/ gerbers out there regarding PFG and XLerator?

Depending on what you want to do with it, I may be able to provide partial info.

However, as Rick says, they are still sold commercially and sales help support other Lisa projects.

Great  :)

and btw, are there any plans/ schematics/ gerbers out there regarding PFG and XLerator?

My understanding is that the MacWorks Plus+II PFG and XLerator are commercial products that are still being made and sold ( in small volumes ).  The developer is one of the Administrators of this site. 

The Sapient Technologies boards cost many-many thousands of dollars to create, so I don't think you will persuade John to release the Gerbers anytime soon.

Is there a utility that will convert a DC42 image of a ProFile to a BLU image that I could transfer over to my ProFile? Since the floppy drive still isn't working, I was thinking about trying to install LOS in LisaEm, converting the resulting ProFile image to BLU format, and then sending it over to my Lisa, but I can't find a utility that will convert from DC42 format to BLU format.

This might work: https://github.com/rayarachelian/lisaem/blob/unstable/src/tools/src/raw-to-dc42.c if not let me know and I'll add an explicit dc42-to-blu command - not sure if BLU checks for the BLU signature or not. BLU is the same format as raw, but with the ffffff block first and in there it has a BLU version #

Easiest way to build this is to build the unstable branch of LisaEm.

Well, it's obviously not a Widget or a SunRem MFM setup so... what is this thing? Maybe it's a SCSI hard drive for MacWorks?

Yes, this is a SCSI drive. I had one of these many years ago, but I do not remember the manufacturer.

Nice idea to use a 3,5" mounting frame for the drive. There is enough space in the card cage to fit a SCSI drive above or below an IDEfile or X/Profile with CF card.

2/10's don't have this issue at all, but 2/10 motherboards are incompatible with 2/5 chassis due to the wiring harness and require the 2/10 I/O board.

You can use a 2/10 motherboard in a 2/5 chassis if you modify or replace the drive harness as shown below. The power harness can be used with either type of motherboard, although a 2/5 harness will of course lack the widget power connector.

I have converted almost all of my Lisae to 2/10. Partly because the internal hard drive connector is more convenient, and partly because the crummy 2/5 I/O and motherboards kept causing trouble.

No idea, all I can tell is this is a 2/5 as there's a LisaLite in there, and the floppy drive doesn't look like a 400k, maybe it's an 800k, if so it came from SunRem, which indeed did sell SCSI cards.

I've seen two types of SCSI cards in photos, some could mount the hard drive on the card itself and provided power from the card. It's possible SunRem made a custom sled and cables to allow it to use the power from the 2/5's harness and snake out a SCSI ribbon cable internally.

The 20/30/40M SunRem made drives have a 2nd board and use the same ProFile protocol. I don't see that board here - and it would be very obvious if it was there, so yeah, leaning towards SCSI. If there were photos of the back with the cover off, it would be a lot easier to tell.

The sled the drive's in seems pretty interesting as it's plastic. It might be a 3.5" to 5.25" PC sled, but drives from that era usually had brass ones - at least the ones I remember. This one seems to have two metal plates on the sides, possibly to bridge the distance for a Lisa drive cage vs a PC one?

There is a bar code on top of the drive, but it's fuzzy so you likely wouldn't be able to use it to get a part number - would be useful if we could.

Did another huge update by digging through old WorthPoint archives... We're currently sitting at around 11,300 systems made as Lisas. Still doesn't account for any of the Mac XLs made in 1985; are we even sure they had serial numbers?

Something else I've noticed is that while AppleNet numbers seem to be sequential, the serial numbers sure aren't.

Somewhat exciting news tonight. While searching for more serial numbers, I came across a listing for what I think is a 2/10 that was loaded with the BPI Systems General Accounting package that was briefly mentioned in the 1984 sales binder.
