Anyone know what this:
is? It has five chips, not six, so it's not the KEF11-BB CIS option. I've
tried Web searches on "57-27889-01", but not turned up anything useful.
All chips on the carrier have the text DC327C-3x (where x is 220.127.116.11.5).
That lead me to "V-11 VAX chip RAM/ROM patchable control store".
And ... KA820-AA.
in the mid of that page. Nice page, hadn't seen that one before.
Cool looking chip!
