3D printed CPUs on the moon?

Well, first processors for IBM S/360 computers was done by interesting technology, CPU by itself was a BOOK(!), with conductors laminated into a plastic pages. Current introduced by input inductors around BOOK (sorry CPU) creates tiny current on output conductors on pages, and that current does all processor/logics  job.

Yes, cooling was major problem (efficiency) to be resolved.

Yes, to change microcode (operations performed by CPU) needs to open CPU’s BOOK, remove old pages, and insert new.

Yes, it was difficult to design such computer (USSR for example just copycat existing pages from S/360), and etc. problems.

But today it is possible to 3D print such BOOK (CPU) as one device from titanium, debug it, tested it (CPU for example can support system of command of a specific, exsisting processor) and then simply re-print CPU  on the moon.

Yep – speed can be slow. Well, size will be big, but old technology can help to make self-suntanned base on the Moon.  All computers required for the mission can be built on the moon except initial amount delivered from the earth.

The same can be done for amplifiers devices required for a communications/input/output units – vacuum and dust on the moon is free, emissions of electrons works same way under solar radiation (instead of heat) and old century’s triodes, pentodes are perfect to replicate by current 3D printing technology.  Why tubes? – Well solar radiation can kill electronics, but tubes will be OK! Story of Kemurdjian's team (Lunokxod-1,2 designer) show interesting twist about tubes – after Chernobil explosions, on roof of the reactor to clean radioactive debris was tried different rovers. All advanced robotics failed in first minutes – and only one was working – on tubes – it was a rover from Kemurdjian's team.

That’s it for today dusty update.
