This is the first I'm hearing that there was a CIS micROM option for
the LSI-11[/2].  I'm very impressed if they were able to pull that off!

I have the QIL CIS micROM for the LSI-11/23, and I too have been meaning
to build a ROM dumper for it, since it's a rare part but could be easily
emulated with modern hardware on a daughterboard (easier than the 11/44
anyway, where the CIS option means extra boards).
