In an old Nuclear Data system that I am playing around with that is basically a repackaged 11/23 with an 8186 CPU card and a Qbus backplane there is an Andromeda System UDC-11 card. This card fits in the A/B slots and the interesting thing is that it supports a floppy and a MFM hard drive. The hard drive was missing when I got the system so have no idea what it was but will speculate that it was a ST-225, hard to go wrong with a 225. Just pushed the whole mess into the shop and will start playing around with it, like I said it has a stock 8186 CPU with the extended memory and the FPU , what looks like a standard four port communications card, the UDC-11, memory card and a internal set of full size set of cards for a onboard terminal. Anyone know anything about the Andromeda card? Want to stuff it in my 11/23 but wonder if it will want to be a RL or RX and don’t know how it will play with the RL and RX controller already in the system? The system also has a full size card that appears to be a large interface to multiple ports or contact closures and may have been targeted at Nuclear Data’s attempt to build a Mimic system? Somehow makes me think of the old Sci-Fi movie Andromeda Strain, anyone else old enough to remember that?
