Hello.
I broke a couple of capacitors wrestling the board out of the trapdoor.
Please can someone tell me the values of C41 and C63 so that I can replace them.
Many Thanks.

Hello.

C41 is 10µF/16V/1206 size.
C63 is 100nf/50V/0603 size.
The latter can be replaced with a lower-voltage version down to 16V. Both caps are on the 5V rail, where it's good practise to have at least a triple nominal voltage for the caps.
Thanks for the swift and helpful reply Jens.
can u tell me what is C29 ?
What are you guys doing to the boards??
C29 is 100nF, 0603 size. Actual assembled rated voltage is 50V, but it can be as low as 10V, because the cap is charged to 3.3V only.
I bought with miss capacitor
Thanks for help
I have another question
Where is possible to download whole manual for ACA1233N?
I have problems with Acamaprom
I want map Internal ROM
When I add to ss
C:ACAMapRom I
after second reset I have communicate
Maprom is all ready active exiting
But if I check Acainfo
Maprom status: disabled
Where is problem can u help me

THe main source of tech info is our technical Wiki:
http://wiki.icomp.de/wiki/ACA1233n
The display of "MapROM active or not" may actually be buggy. Please try the Bustest tool from Aminet and see if the performance to ROM changes before/after activating MapROM - that's a very good indicator. We do have work to do on that software package, so if you can confirm a bug here, that would be subject to be fixed in a few days.
I got some like this https://drive.google.com/file/…e1L94kb/view?usp=drivesdk
In that screen shot, ROM speed is much slower than Fastmem speed, so MapROM is not on.
I know now is go from internal amiga kickstart
But how to turn on maping internal ROM from ACA1233N ?
I told u only first time reboot after signing in ss C:acamaprom I work fine
Next reboot I got communicate Maprom is all ready active exiting
So is mean no enable
Next reboot I got communicate Maprom is all ready active exiting
That's expected on the second boot, because MapROM is reset-resident.
