...on impulse and with a noticeable lack of rational thought I bought an old 80s Carimali 1 Group on a local auction site - it was a bargain (I think - about US$150) and I couldn't resist. However, I am now suffering a significant amount of buyer's remorse, as it is a bit larger, more basic than I was expecting, and the pump is AWOL. It did come with 2 portafilters however and is in pretty OK condition physically (under the grime). I still haven't told the wife, hence all of these photos were taken in the back of my car.
What I am trying to decide (before I confess) is if I should restore/modify this machine - or whether I would be ultimately wasting my time. Up until now I have been quite happy with my saturated group SBDU machine(s) and never considered getting an HX. Still, who dares, etc. I have the mechanical facilities to do all of the work myself, originally being trained in electronics and restoring cars as a hobby.
I also don't know how some of the doodads in the following pictures work, so any help in explaining what they do would be great.
Some photos:
What are A and R positions on the power switch, anyone know?

It seems to have some kind of wacky electric volume control. I have no idea how it works, there is a micro switch in the 'foot' against which you seem to place the cup. I would swear there are not enough wires to do anything much intelligent - there is only one wire going somewhere - and how (or if) it works I would love explained. Close up of the 'foot' below. All the lever on the front of the machine seems to do is raise and lower this foot.

A back. Hmmm, 80s colors...

Yep, the machine is pretty dusty and dirty - not super bad though.

I assume this gauge is the boiler pressure and is set using the pressure stat? It effects the ultimate brew temperature through the HX - is that right? I am a HX nub

Hidden up where it is almost impossible to see, this is the brew pressure? Usually set by the rotary pump bypass (which I don't have anyway)?

Dodgy wiring, pressure-stat and a leaky boiler.

Yep more old old leaks.

Is this the controller for the boiler autofill?

Grouphead does not seem to be heated, by thermosyphon or electrically - and it seems it is only connected to the boiler by two 3mm thick steel plates... I thought they usually put more effort into heating the brew head than this. Is there anything I can do here in terms of modification? Is it possible to retrofit thermosyphon or an electric heater?

Last photo, a very odd 3 way valve to my eyes.

So, I am seeking opinions as to what I should do with this old girl. Seems like it could be a fun project, but only if it will eventually make decent coffee. I have seen that I could PID in place of the pressure stat etc. I don't understand the volume dispenser, so I don't know what to do there. There is very little (none) info out there on the internet for these Carimali machines, and believe me - I have looked. I guess that is also part of the attraction to me, I have never been one to follow the crowd. Having said that, I have found a very similar model (but with a sexy sexy lever) on a German website http://translate.google.com/translate?h...26rls%3Den That is it. Would you keep the case? Would you rebox it into a smaller package with a PID etc?
Any and all opinions and any information/advice is welcome.
If it does end up being promoted to project status, I will fit a vibe pump and test stuff before going too far/dismantling. I guess the other option would be to part it out - but that would be a shame...
