ProfiSet 32kb Manual

The switch positions A0,A4,A6 set the ProfiSET OS or +RAM to the specified address.
The port numbers set the ProfiSET OS to the specified port address. AFAIK the PS OS is 8K normally.
I think I also had a version with 16K ROM, which included software for the MBK PS EPROM burner.

At least one version I had also included the "FAST mode" software turbo mechanism,
which consisted of faster versions of certain 41 OS functions, and an associated "compiler" or translator,
which took user code programs, and replaced certain 41 OS calls by FAST mode calls.
I don't remember whether the optimized UC programs ran in +RAM only, or in main memory, too.

The PS with 32K +RAM had 3 useful switch positions (IMHO) for the +RAM only: OFF, init, Port 1+2 ,
since all other positions interfered with other addresses. The 16K +RAM version was much more flexible in this respect.


OT and BTW: I had several PS units over the decades.
My first PS had init 010, which I bought new from Winfried directly,
and on which I compiled the original 4K CCD OS/X in the mid-eighties.
My second-last unit, with init 024 btw., was sold abroad a few years ago. Maybe it arrived at Sylvain;-)

But I think to remember that Winfried once told me on the phone that at some point,
they just copied the PS ROM EPROMs with the same init number (024),
so it's perfectly possible that there exists more than one unit with init 024.

One of my later units had different (and fewer) RAM chips, since after several decades,
the original RAM chips weren't available anymore.

I still have some of the original and unused PS batteries,
which surprisingly hold some voltage after more than 30 years.
