If i take too long to reply, sorry my cat is sleeping on my laps.
Re: STE Booster instable
Hiya,
SIMMs arrived, tried them out, no change
When I have some spare time, I will recheck the soldering connections and see if 16MHz improves anything.
But I guess, the socket construction simply is crap and I will have to rethink my strategy

If I interpret M9-1-122J correctly, it is 9 pin, bussed, 1.2k with 5% tolerance.

Re: STE Booster instable
It doesn't take much to push the STE over the edge. A slight bit of noise in the wrong place and total chaos. Its why it takes me so long to debug boosters, its more like 1 day to design the things, then 6 months tracing why the thing isn't stable. Its even worse on the STFM .

Re: Help resolving STE Booster instability?
Yep. And it sucks even more, when you have no scope. But I just sold a refurbished Amiga 500 for 210 EUR, so I guess next month I will be able to order my Rigol DS1054Z.
I guess it will not make much sense to continue searching for the cause, until I have the proper equipment. At least today my desoldering station arrived... a chinese cheapo, but I guess better than 2 km of solder wick

Re: Help resolving STE Booster instability?
Damn it... I confused GND and VCC on the booster board, and managed to kill the CPU and probably the GAL...
When replacing the CPU with the original one, it still wouldn't work, I had to reconnect the original CPU clock, then the system booted again. So I guess the CPU is definately gone, and the GAL and/or more components on the booster PCB as well.
So I need replacement, but what do I do?
For hacking into the machine, the 1.5 Booster seems a simpler choice, but can it do 32MHz?
And of course, I will need a new MC68HC000...

Re: Help resolving STE Booster instability?
I ran it at 32mhz for the "prototype" for the STE V1 booster. Though I only tried it on that one machine, while it works, I cannot say if it would work on any other machines without issues.. So you probably would be better hacking in the proper STE booster.. I can send you a new CPU & GAL if needs be..

Re: Help resolving STE Booster instability?
FINALLY!
With Exxos help I managed to successfully push my STE to 32MHz... and not only by using the STE Booster, but it works with the 1.5 Booster as well
Now I'll do a write up in the Member Blog section for others to scare off

Re: Help resolving STE Booster instability?
Congrats!
You may need to tweak some resistors if using V1.5 and you have stability issues.

Re: Help resolving STE Booster instability?
I had it run GB6 loops for a couple of hours (100+ iterations) and had not a single crash, so I am quite positive But I will do some more testing.
