OK, some things are clear now 😀
Still, many mysteries remain.
53-000366 - vetz, fo you have a picture of this one?
I have pictures of 53-000331 being BOTH ReelMagic and ReelMagic Lite, with CDs etc. missing in the latter case. Probably Sigma did not bother making separate board models at first.
53-000347 - it would be nice to see some pictures with actual 'ReelMagic 2' label. All pictures I have of 347 "Rev.B" are rebranded HTM models.
53-000387 - you are right, it is some later model of REALmagic Lite.
53-000417 and 53-000411 - I am curious how 417 could predate 411 by a whole year?
RealMagic Ultra - yes, the biggest mistery.
Why would the official Sigma site list pictures of Maxima and Ultra with Sigma 7000 chip instead of CL-450 we see on actual cards?
Sadly, the only certain way to know the exact model is either opening a sealed box of it or testing it on old PC. I remember bying a RM-card designated as 'Maxima Pro' on eBay - and discovering that no Maxima Pro drivers work with it, and the card is denoted by Windows as 'Ultra II'. That was the only way to discover it is actually Netstream 1, as only those drivers worked with it 😀
53-000569 - are you sure that's a kind of Hollywood Plus? I thought that was Ventura Plus?
Netstream 4000 - are you sure that's 53-000694? I thought it was 53-000663 (although that could be 'Dragon II"). And this picture shows it is 626, the same as NetStream2000!
RealMagic X-Card - you list it as EM8475LF, but my card has no LF.
