1882 Technical Information
For all intents and purposes, the 1882-00 and 1882-01 are identical; with the exception of the personality interface modules.
Both variants have the same piggyback logic board - PSR EAGU ULA 34327-00-3-15 / 19-11-84/6(L)L4
The 01 sometimes has 4 x TR1965-PL UART ICs but these are equivalent to the original AY-3-1015D ICs (Datasheet available below)

Each channel within the ALME has 15 associated jumpers - this image shows their meanings.
The reason for two BAUD rate settings is to allow for independent setting of the TX and RX speeds.

The ALME also contains a master clock generator that is used by the 4 x UART ICs.
The settings for this master clock are shown in the image on the left, but note that changing the master clock will affect ALL four channels on the board.
There's a datasheet below for the MC14411 for anybody who's interested.

Unfortunately, the RSB signal for the master clock is supplied by some of the ALME electronics and it's not possible to see how this signal is manipulated.

Things to note.
You CANNOT connect a VDU to channel #1 of the first ALME - it's reserved for the remote support modem connection (at least under Niros 7.0)
