no, i was short of jumpers so there is a wire soldered.derkom wrote: 08 Dec 2019 16:58 Are you missing the jumper in the Flashy Clock socket area? That may be affecting your reset behaviour.

DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

Re: will it compute? btl's attempt to build the H4
Did you use a original switch ? And exact part number for the reset switch and LS chip next to it ? Soldered reset ic in the right way ?

Re: will it compute? btl's attempt to build the H4
Yes, i used the switch of my donor 520ST.
I can report keyboard and mouse working, too.
Will check my mouser order if i got the correct reset IC. It is soldered correct orientation, that much i could double check already
My next Atari time frame is on Tuesday :?

Re: will it compute? btl's attempt to build the H4
You might want to check R13 and R919, they can very easily be confused...

Re: will it compute? btl's attempt to build the H4
Thanks Ingo,
i checked but they were correct. then i checked my Reset IC, and indeed, no idea how, but i ordered the wrong part.
Same functionality, but "active high" logic, soinverted logic than expected. I'll try to find the correct one, but mouser
wants 20€ shipping for a 0.58€ part. If someone knows a seller in EU with reasonable shipping, let me know.
For now, i left out the chip and rely on the reset switch only. I know, thats not good and may produce trouble,
but its only temporary.

Re: will it compute? btl's attempt to build the H4
I think I ordered a couple more than I needed, let me check tonight. I could then send you one, if you PM me your address. You are in Germany as well, right? And the part number was SN74LVC1G11DBVR ?

Hi,
yeah, i'm in germany. The parts was U$6 RESET_IC SOT143-4 STM6315RGW13F
it would be awesome if you have spare for me!
greets,

OK, now that i've overcome my first oopsie, i connected a floppy disk drive.
Time to run a GB6!
It does compute! :cheer:

Re: will it compute? btl's attempt to build the H4
Well done and interesting to see it's a little too bright on your 1084 as well.
Time to experiment with those 3 resistor values on the rgb circuit.

If it ain't broke, test it to Destruction.
