I have an opportunity to buy a surplus Racal-Milgo RM-1822DS which, apparently, is a repackaged Telebit. However, I'm not sure which Telebit it is. The Racal-Milgo documentation is dated June 1987. The Telebit "Packetized Ensemble Protocol Modem" documentation is dated: Firmware Release 3, October 1987. Here are my questions: Does anybody know if this is just an exterior repackaging, or has Racal-Milgo done anything special to the modem? Specifically, which Telebit is this? It will do: 300 bps Bell 103 1200 bps Bell 212A 1200 bps V.22 2400 bps V.22bis I would imagine the Firmware has been updated since then. What does it take to get it updated and can it be upgraded? Who is Racal-Milgo? I've heard of Racal-Vadic (sp?) but not -Milgo. If these guys still exist, are they known for their service or can I just skip them and go to Telebit (who is somebody I know better)? Finally, what is a fair market value for this modem?

Version AA3.01-AB3.00 (aka Version 3), was the last version released for the original TrailBlazer. It would appear that this modem has been upgraded at some time in the past. Version 3 had the main characteristics of present-day Telebit modems. Protocol Support, oodles of S-registers, MNP3 (and a bit of MNP4), and PEP, though PEP Data Compression is not supported. > >Does anybody know if this is just an exterior repackaging, or has >Racal-Milgo done anything special to the modem? > Nothing out of the ordinary about it, especially if it has the Ver 3 firmware chips installed.

There is a trade-in to a T2500 available, but the price may be more than you might pay some of the mail-order sources for the same modem. Check with Telebit tech support if you want to investigate that option. > >Who is Racal-Milgo?

I believe Vadic made lower speed modems and Milgo made higher speed ones - at least for a while. (one reason they OEM'ed the TB from Telebit) Modems aren't the only products Milgo makes, but I don't know too much about them. >* Chip Roberson, RD&E -*- Internet Domain: <roberson%aurgate@mcnc.org> * -- .------------------------------------------------------------------------. | Greg Andrews | UUCP: {apple,amdahl,claris}!netcom!gandrews | | | Internet: gandrews@netcom.COM | `------------------------------------------------------------------------'
