It’s not mentioned but the ODRA 1300s were ICT/ICL 1900 compatibles, pretty far from the Western state of the art (circa early 1960s).

At the time Odra 1300 were in R&D, they were on par - in fact, ELWRO and ICL cooperated, so the hardware was locally designed but compatible, and base software was essentially localized from ICL one + local software packages.

This built a pretty good starting position to work on more advanced designs, but then certain stupidity happened in form of ES ("Single System") initiative, which a) was based around S/360 when S/370 was to be released b) ELWRO was assigned "mid performance" machines when it could actually deliver a much faster one.

I don't know for certain how true it is, but there's a legend that ELWRO prepared a design based on their best, but compatible with S/360 and thus rest of ES EVM - just way faster in smaller frame (effectively imagine top-tier S/360 CPU but in way smaller package), and kept true performance details secret until accidental leak caused a small but impactful political shitstorm that canceled the efforts.

Wasn't that produced as R-32?

		My understanding is that while R-32 did benefit from the technology edge that ELWRO built up, they actually tried to build a much faster model than R-32. Unfortunately, it's really hard to get reliable sources about some details.

I meant that the 1900 itself was pretty trailing edge, not to cast aspersions on ELWRO.
