@Bootdisk, to answer your question, ICD *DID* in fact have Mac and Atari ST versions of the AdSpeed, though the AdSpeed for the Atari ST was different since the 68k CPU in that thing was a PLCC form factor. AdSpeed for the Mac looked just like the AdSpeed for the Amiga (but it had blue lettering on the label instead of red).
We never sold many of the Mac version because its 68k CPU was soldered in, and those original 68k Mac were hell to crack open. As such it required two things Mac enthusiasts feared greatly (technical expertise, and seeing the inside of a computer :roflmao:

Plus you had to get that Mac case cracker tool to get inside w/o destroying the case, and you had to avoid electrocuting yourself on the exposed CRT.
Ugh..that made recall a tech support case from hell...some fella with a Atari AdSpeed called up, super distraught over having installation trouble, and believe it or not, got so upset he threatened to commit suicide on the phone. We got his local policie depts and suicide prevention hotline folks to get over there. I give a lot of points to Howard (he was our Atari ST dev/support guy) for keeping this guy from losing it long enough for the cops to get there. Tech support never gets paid enough

. I know I worked through a few cases of rabid end users myself, but did manage to switch one angry T-Rexx user from wanting to kill me, to offering to dance at my wedding (no I did NOT take him up on it). Some days it seemed I was less of tech support and more a psych counselor.
I got some odd and interesting support letters while I was doing ICD tech support.
1. A letter from a 14-year old Polish kid who was basically asking us to give him an AdSPeed, well we did NOT given him an AdSpeed BUT we sent him a T-Shirt, a hat, and some ICD stickers
2. Got a letter from some researcher in Iran who was trying to write a 020 emulator to run on the 68k (since Iran was and still is under a tech embargo and the 020 was a forbidden export to Iran, he wanted some help trying to use an AdSpeed for the job, but we had to tell him no or have the Feds comedown on us.)
3. Got a support phone call from a A500 AdSpeed user in of all places..Leningrad, Soviet Union! Pretty wild to be getting calls from Russia BEFORE the wall came down, and to discover there were Amigas and AdSpeeds being used there.
I still have a envelope/stamp collection of all the support letters I received while I worked at ICD (Supported customers in over 43 nations, and on ALL 7 continents, and yes I do mean all of them. A lot of folks don't realize just how international the Amiga was, and really how North American a phenomenon the PC and the Mac were at the time.
