Info about rom:
Early versions of the Juno 106 boards used a D7810G CPU in combination with a ROM chip with the operating system. Later Junos had a MASK ROM CPU, with the software programmed internally. These MASK ROMs are no longer available, but they can be replaced with the first CPU, in combination with one of the following Eproms, each of which contains the last OS software:
A5 – for the CPU Board (IC2)
B2 – Module Board (IC37)
