JiffyDOS Forensics

Please feel free to repost on other forums, I'm trying to catch as many people as possible: As many of you are probably aware, I acquired a license to sell JiffyDOS earlier this year and am now ramping up sales. To that end, I am trying to reconstruct the exact product offerings that CMD offered. This means verifying images, and determining what original ROM images CMD supplied with each overlay. Thus, if anyone can use a DOS ROM reading utility (or EPROM reader) and can send me a copy of the both halves of the JDOS ROM, I'm still struggling with the following systems. 1571: I have three versions here, but cannot determine which is correct. The MD5s are: 41c6cc528e9515ffd0ed9b180f8467c0, 6b4d46b28b7414d5a82cea4972894600, and d649fa6b0108c20ce213f5496d5980a5. What is the version number on the ROM sticker?) 1571D: I have a 1571D JiffyDOS ROM here, but it looks to be a 1571DCR (the cost reduced version). Notes indicate a non-CR 1571D used a normal 1571 JD ROM overlay, but I'd like to verify that. MSD SD1/SD2: I am trying to determine the version of MSD code in the lower half of the U5 JiffyDOS for SD2. The MD5 is 1a2efac3b96decf83fba27bc17c5a8a7. I checked against my SD2-2.3 version here, but they are different. Also, is the SD1 JiffyDOS the same as SD2 version? Indus GT: I do not have an original JDOS for this, so I need a dump to compare. 1541C: Again, I do not own an original JDOS for this machine. I understand there is a Swedish version of JiffyDOS for the C128 and C128D (and possibly for the C64) [Update: I have been sent copies of the Swedish JiffyDOS ROMs, but I'd still be interested in what version of KERNAL was included as the "original" KERNAL for these units.] German/Finnish JiffyDOS variants? Any help folks can provide would be much appreciated. In fact, if you have an original JDOS, no matter the type and can dump it for me (both the original and the JD portions), that'd be great. Anything you can tell me about the setup - sticker legend (version number, etc.), machine variant (128, 128D, 128DCR, etc.), video standard (PAL/NTSC), and whether it had a switch on the ROM - is good information to share. To clarify, I know there are bootleg archives available, but I can't consider them authoritative. In addition, the archives would not tell me what CMD placed in the non-JD half of the EPROM on units with switches. I would prefer to check against genuine copies of the overlays if at all possible.
