I first encountered RTL technology when i was a kid, probably 14 or 15, rummaging at a local electronics surplus shop, looking for cheap boards to salvage parts from, and saw this odd board full of small modules in which components were sandwiched between the main board and the many mini PCBs it contained, each one, as I later discovered, made a RTL logic gate. It cost almost nothing, so i bought it and salvaged a good number of transistors from it, all marked with the SGS-ATES logo and internal numbering that made them impossible to identify, although they all worked in the non critical experiments a kid might try in the very early 80s.

The interleaved rows of these modules made for very dense circuit packing for the discrete component era.
- squarefoot 3y agoNot identical but quite similar: the mounting style and board arrangement was the same, although in my case all transistors were in TO-18 metal case, all resistors 1/4 watt, no inductors, diodes were very rare and the small board were green FR4 just like the main board.
