Appleline likely a modified DCA IRMAprint?

Hi all,
As I have recently got a few Lisas, digging around and learning about it and requisite hardware I quickly learned about the Appleline and Cluster controller.
As one of my primary focuses in the hobby is IBM hardware midrange and mainframe it quickly caught my interest. Unfortunately it seems they are quite uncommon to find floating around nowadays.
After looking at photos of it I couldn't help but notice it looked very familiar.
It looks almost exactly like a DCA IRMAprint.
It even has a very similar port layout, same switch position and same 24VAC input voltage.
The most common IRMAprint you can find is parallel, they did make a serial variant too though, which I suspect to be the version they modified for the Appleline.
I am wondering if it would be possible to convert a DCA IRMAprint into an Appleline but I'd need good photos inside of an Appleline, front and back of the board preferably, and rom dumps to confirm this.
Does anyone here have an Appleline and could do this? There is very little info about the Appleline online from what digging I have done. There is the one manual and a few photos but that's about it from what I've found.

Thanks!

Paging @compu85, @compu85 to the white courtesy phone please :) (cf.)

I had never heard of this thing! I was familiar with the Cluster Controller at least, which I'd also heard was a rebadged part.

Hehe, I had thought about buying those IRMA units a few years ago and didn't. The serial one is identical to the AppleLine, except for the case (going by the photos anyway).

Attached is the firmware from my unit.

And some pictures (annoyingly, no internal photos): https://picasaweb.google.com/113574813556450463594/Apple3270AppleLine

THANK YOU!

I've been trying to find someone willing to dump the AppleLine firmware for a while now since I've been unable to find one!

Al,
Do you have dumps of the firmware from the IRMAprint units as-well? I just ordered a Serial and Parallel unit which I plan to dump for comparison. I will post those here if your looking for them.
