DO NOT USE DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time it is unfortunately not possible to white list 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!

Another one but with some odd adapter RAM board

Re: C070243 REV.H
That looks to be a rather neat RAM board actually. The regular 41256 chips are 16 pin 256kx1, and the only real option is to piggyback another 512KB on top of the existing. That board takes 18 pin chips which means you can use 421000 (511000 in this case) which are 1Mx1. So, that should be a 2MB RAM upgrade.

Dear Exxos,
there's no information on bus-resistors replacement for that exact motherboard (C070243 REV.H):
viewtopic.php?f=17&t=2235#p27504
Could you please advise if all of them can be safely replaced with 2.2kOhm? There are 6 of them, if I see it right.

Re: C070243 REV.H
Its not something I have tried or documented on the STM. I suggest not changing them unless you have issues.HCRX27 wrote: Mon Sep 15, 2025 7:47 am Dear Exxos,

Re: C070243 REV.H
There are issues with loading HD adapted games from SidecarT or IDE HDD after I replaced CPU to 68HC000 in HyperCache turbo (16MHz + cache), because the NMOS wanted to burn the keyboard above it alive 
Loading from Ultrasatan with no SidecarT attached is working fine, though, with good overall stability.
So I guess, replacing them all with 2.2kOhm should do no harm either for HC or if I stay with NMOS?

Re: C070243 REV.H
I'm not aware of any issues no. I'm sure others have changed them without issue.HCRX27 wrote: Mon Sep 15, 2025 9:08 am There are issues with loading HD adapted games from SidecarT or IDE HDD after I replaced CPU to 68HC000 in HyperCache turbo (16MHz + cache), because the NMOS wanted to burn the keyboard above it alive

Perfect, thanks a lot!
