I believe your battery holder is in backwards. Also don't forget r908 as I did.. gives you 20 bombs.IngoQ wrote: 03 Jan 2020 13:27 My back is getting better, so I here is some progress:
All sockets in place, only some of the resistors are missing, and then on to the fixes. I'm positive I get it finished this year :mrgreen:

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: IngoQs attempt at messing up the H4
Thanks, corrected.
Already fitted, thanks again :)
All parts are now soldered in and on, at least my list has everything striked off. Will now clean the rear (easier, when there are no bodge wires) and then apply the missing patches.

I counted 3 :-P DTACK, SIMM and MAX238 ;)
And here they are:
And in addition: The DMA workaround:
RGB next, lastly the ICs and then the moment of truth... but playtime for today is over :)

One wire to many on the buffer bypass for HDD. You need to remove the leftmost wire.

Re: IngoQs attempt at messing up the H4
Okay, I believe I am done:
Sadly no time anymore for a test run, will have to wait a bit... And I have to admit, I am a little scared ;)

Re: IngoQs attempt at messing up the H4
It's alive :mrgreen:
Haven't fully tested it because of a lack of working floppy drives, but at least got it to run GB6. Seems quite stable to me, and no complains about the video quality either.
The DAC is getting quite hot, is that normal?
