I asked around and, as many posters suspected, the box was part of a
larger system : A Sentry IC tester, made by Fairchild. That would
explain the use of the F8.
The row of DRAMs I thought to have seen was, at closer inspection, a set
of bipolar PROMs. Total real ram on the board : 4 x 2114. So no CP/M for
sure....
Still, I have never before seen a floppybox with printeroutput !
The CP/M disks (SSSD) are therefore most probably from another, unknown
system.
