It is no original DEC RXV21. It is a third paty product, "MXV21" made by
"MDA". There is all the stuff on it to make it a complete controller.
Read/write circuit, 2 x AM2901 with all the AM29xx stuff around it,
TMS4044 SRAM, ... It has the usual 50 pin connector for 8" floppy
drives. If I plug it into one of my QBus VAXen it is shown as RXV21 by
the "show qbus" command.
