Digital Display for FRG-7


 

Hello
?
I've just joined this group and have a mint FRG-7...it came with its box and other bits.?
?
A friend gave me an old digital display unit which turns out to be a Timestep Electronics DFC-7 from 1981. It uses an OKI MSM5525RS LSI chip and a couple of others, one being an unmarked round can.
?
Does anyone, by any chance, have some information on the kit please?
?
Thanks
?
