[B2000-CR] diagrom 1.0 help

Hi,

Can somebody please point me in the right direction for instructions on using diagrom, I'm trying to resurrect a B2000-CR 4.3, Kickstart 3.1 comes up, OS 3.1 install silently fails, diagrom gives no on screen menus, its pretty confusing, I think maybe i need a serial console setup?

I don't see any battery leakage or damaged traces, there is the inevitable oxidation and cleaning and reseating got me to kickstart, I suspect RAM as there is that cluster of like 32 RAM chips and RAM might explain how its acting. I do have a donor -CR that I've been scavenging from. I could desolder all the sockets and put machined ones on there.

I'm going through an OSSC, I need to wire up a DB9 to the Bruktmoped mouse adapter.

Maybe diagrom only works on composite, not sure, should I pickup a newer diagrom?

Stupid Google Search AI is making things way harder, Google keeps giving me crap results and luring me into AI where is proceeds to hallucinate a bunch. Are there schematics for this board?

Thanks.

FFB throttle

I'm building a throttle, using a pancake motor, encoder, driver, PSU and MCU. I plan to use SimpleFOC and vibe code. I've built the steel frame, I'll 3DP an outer enclosure.

I'm going to start with anti-cogging and virtual detents (mimicking mechanical cutoff/idle/afterburner detents).

Force feedback from relevant telemetry?

More resistance at higher G's?

An additional encoder to set a virtual "clutch"?

Rate dependant viscosity?

Lighter detents for a certain fixed throttle increase?

Auto throttle?

Disable afterburner when fuel is low?

Sequential shifter or collective modes, there could be interchangeable 3DP gates, clip one in and have the code hunt for the limits and set the mode based on the travel measured?

What features would you add, any thoughts?

Motorised throttle

40mm fans...

Has anyone tried 40mm fans in a 3 push, 3 pull config, i was thinking of 3dp two shrouds 120x40mm on the fan side and tapering to 120x20mm on the heatsink side?

Reason I ask is I already have six Noctua NF-A4x20 PWM.

I don't have my BC-250 yet.

AM6B+ state of play?

Apologies if this is been covered.

I'm fairly confused on next steps, my AM6B+ is running CE 21 just the standard one with the copied dovi.ko, it works fine with TV led FEL. Updates stopped months ago.

So I started looking at CE 21 builds with fixes and backports, P3i T4 being the one thats getting the most airtime.

But I read that they got dovi.ko working on 5.15 and therefore CE 22 is now working on AM6B+?

So what gives, is CE 22 the way to go or are there reasons why CE 21 is still on top?

Thanks!

DIY "tilting multi-mode" simrig

i went overboard giving the rig adjustable tilt.

i wanted to keep the footprint small.

i'm using a psvr2 headset.

there is a dayton 300ex bolted under the seat.

sequential shifter is installed on the armrest, throttles attach there as well, I left space on the armrest for switches.

the flightstick is attached to a DIY gooseneck and that's attached to a steering QR adapter.
