That got me searching, looks like anyone can get an Aiphone "tenant monitor" for $30 BIN + somewhat overpriced shipping from our favorite internet auction site, looks like the same type of 4" monochrome "lollipop" CRT: http://www.ebay.com/itm/AIPHONE-MB-V...item27cb72c854

Also found this PDF which explains how they are to be connected: http://www.aiphone.com/data/pdf/prod...eo%20Instr.pdf

Another manual, looks like it was published in 1997: http://www.aiphone.com/data/pdf/prod...MD%20Instr.pdf
