Hi, I have recently bought a Real Time Clock module and fitted this to my ACA1233n. Initially my Amiga 1200 did not boot but after re-fitting everything again it booted.
I then set the time and date via workbench. However when I powered down and left the Amiga switched off for 20mins I loaded up again and noticed the time had not saved using the real time clock however the date had saved. So I set the time again and before I turned the power off I decided to check the ACA1233n to see if it was behaving ok.
What I got was half the speed nearly when running a speed test. The speed was 5567 dhrystones where as I normally get 9201 dhrystones or else 9061 dhrystones. It is never this slow. So I decided to power the Amiga off again anyway and check later on if the date and time had saved.
The did not save. Both date and time where incorrect on bootup. So I figured there is something wrong with the RTC module I bought (it had a battery already fitted). I then went to check the speed of the ACA1233n and I noticed I was still getting slower speed than normal when the CPU was set to 40mhz. The speeds I was getting in sysinfo this time where 8567 dhrystones and fluctuating back and forth to around 9060 dhrystones.
So I then removed the RTC module. When I booted the Amiga 1200 again to check the accelerator without the RTC the speeds where normal and I got 9201 dhrystones over a period of an hour consistently.
So I am wondering would a faulty RTC cause such issue with the ACA1233N card?
The seller of the RTC also would like me to check the RTC module using the Amiga 1200 RTC header on the motherboard, however am I correct in my understanding that the Amiga 1200 RTC header cannot be used when you have a ACA1233n installed?
