DPM01 DECdataway terminal multiplexer ("a microprocessor-based peripheral interface")? http://bitsavers.trailing-edge.com/pdf/dec/terminal/EK-VT110_UG-001_Dec78.p… -----Original Message----- From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Al Kossow via cctalk Sent: Saturday, February 10, 2018 11:50 AM To: General Discussion: On-Topic and Off-Topic Posts Subject: anyone recognize this blank board? https://www.ebay.com/itm/311965565048 The same seller has a VT180 and some variant of the VT100 with an expansion board I don't recognize Interesting thing about the blank board is it says "VT-11X" on it and it looks like it would have been an 8-bit CPU looking at the string of DRAMs on it.
