A project log for YGREC16 - YG's 16bits Relay Electric Computer

Fork of #AMBAP, here I discuss about the physical implementation of the bitslice architecture with russian РЭС15 (see what I did here?)

I've been much less active lately for very good reasons, the most important being to renovate my whole workshop. I Had to let go of quite a lot of old gears but I found some "forgotten treasures" though (it's always a matter of perspective, of course).

One of them is a Sinclair SP200 dot matrix printer with the standard Centronics interface. 8-bits glory and shipped with the internal schematics and protocol ! What better peripheral output could I have ? I even have a stack of continuous paper for it...

I haven't tested it yet but it was bought around 1990 and I remember having to source a new ribbon in the mid-90s. Today the ink is certainly dry...

Who can help me rejuvenate the ink ribbon ?

You have a lot of projects. How do you ever finish anything when you have so many going at once!

Some are finished :-)

LOL.  I on the other hand, have never "finished" a project in my life.  I can pick something I threw together in a weekend ten years ago and rattle off five things I've always meant to improve, fix, or re-do.  If I waited to finish any one of them, I'd never get to work on anything new :-)

Working for clients is a great way to break the neverending spiral of hacking :-)

But there must be a balance between finishing a project (which is really exhausting) and recuperation/recovery/creativity. Thankfully I have become better at this :-)

I remember spraying one with WD-40 at one point and manually winding it around to distribute the ink/solvent.  There may be a better way and/or solvent.

that's an interesting idea... solvent...

Indeed!
Long ago I had surprisingly good luck with old ribbons... what must've been sitting around for years if not decades still functioning. I bet solvent would be even better.
