Solartron instruments are, not suprisingly, fairly

have an LM1420.2 (the .2 meaning it's got the BCD output socket on the
back), which is all discrete transistors with nixie tubes for the
display. And a somewhat better model (LM1602???) which uses DTL chips.
The former certainly contains a Seston Standard Cell, I suspect the
latter does too (ass, incidentally, does that Blackburn valved DVM I
mentioned in another message).
A DVM with a built-in standard cell?? Neat! Got pics and/or
schematics? I'd love to see that.
