chips are great, what about technologies tho?

@finkmac what do you mean?

The company I worked for in 1992 developed a C&T F8680 based PC! It was fanless & IP65 (or 66) level waterproof! I adapted our Intel 28F010-based Flash drive drivers for it using SuperState to emulate IDE. I also wrote its BIOS (in 'C' instead of assembler, which was quite daring). http://www.bitsavers.org/components/chipsAndTech/F8680_System_Design_Guide_1991.pdf

Hi @Snial !
I'm looking for F8680's register and SuperState R documentation to do roughly the same. Do you still remember how the superstate worked? Any public document I was able to find only mentions its existence and the wikipedia page only describe two instructions which I know is incomplete.

@pc2005 , https://datasheets.chipdb.org/Chips/F8680A_Rev_2_0.pdf is the data sheet Rev 2. I may have some additional documentation in my Dad's attic, I'll check. We certainly had the documentation. Mostly it was an 80286 type instruction set without Protected mode as such, but you could do things like PUSHA. There were extra segregs (all 24-bit).

@Snial Additional info would be awesome (extra segregs :-O). I've found 1.1a, 2.0 and the System Design Guide datasheet, but "Programmer's reference Manual" is not online (and superstate + CREGs are presumably documented there).

@Snial I think I've managed to reverse engineer those segregs! https://www.vogons.org/viewtopic.php?p=1426316#p1426316

@pc2005 . I didn't manage to get around to searching for any docs the last time I was at my Dad's. It's still on my list!

How can I unsubscribe to my profile post discussion?

hey @croissantking how are you
