No problem.
Next week i'll see if i can dig up a sheet that has all the version info on the older system. But in the mean time if you look at the chips on the backplane in the cabinets of the DCS/DCSc if they take CID it they will say it right on them.
I actually work with the guy that installed the first 816's before it was purchased by Samsung so he knows every version of software inside and out up until the 7xxx series, i can bounce any questions you have off him.
I'll PM you my email if you would like to use that, i answer it faster.

You still have a 400si?! Dear lord, why?! That thing was SO horrendous... the only upside was the cards were big enough to serve as a table if you needed to eat a big lunch while trying to recover from a crash!

Down here the dcs/compact 2 required 6.33 software or higher to run iDCS (falcon) handsets.

The DCS616 requires 1.30 or higher to support OS handsets (except 21b), can't remember what version supports idcs/ds24d

The iDCS100/500 requires 1.34/1.36 or higher to support
OS handsets (except 21b)

Not sure if you guys got what we called 24b ivory (kr24b is what they showed up as in the dcs pcmmc) they required v5.x or higher to run on the dcs/compact/compact 2

The DCS500si sounds like what we called the gateway, terrible thing to program.

The dcs compact didn't last long here (horrible thing, but better psu then it's successors)

I'll take some pictures of our stock and post them here so you can see what i have to deal with on a daily basis. 90% of our service calls in territories are for 816's/DCS'(c)/iDCS systems so we can't get rid of this stuff.
