Title: GenRad 1657 RLC Digibridge
Post by: Mr Eastwood on April 02, 2015, 04:35:40 PM

Here's something I acquired the other day;  so far I've checked the power supply, and cleaned and re-seated all the ICs;  I've replaced a dull led and ordered some replacement 7 seg drivers to replace a bad one.

The MPU is an early 6503.

I replaced one of the drivers and left the unit on for 2 days to see if anything else would fail before I put it all back together again;  when I get time I'll order a set of Kelvin clips for it.
