That option is for Windoze keyboards with a missing second windows key, as your amiga keyboard has both left and right amiga keys it should work fine without it.

True. After some more tests, it doesn’t need that option.

It still seems to me as the Amiga keyboard isn’t mapped correctly. Doesn’t recognize the “\” key, the “help” key is identified as the right “Alt” key and it also doesn’t recognize the “(“ and “)” keys on the numpad (“NumLock” and “ScrollLock”).

I tested the keyboard with Amiga Test Kit.

The user @birko70 reported this issue with OS3.2.3 but it seems a system wide issue.

I’m also using the original Amiga keyboard. On the initial setup I left the option “105 key generic keyboard” and ticked the option “use alt as amiga key”, since I saw this on a video. Is this configuration correct? Haven’t tested every keys but the keyboard works in general.

     On my A1222+, v1.50 seems to rotate the objects more quickly.  I don't know if it's because v1.50 has improvements over the older versions or if it's due to the fact the A1222+ has OS 4.1 FE, Update 3 installed recently.  Anyways, very nice...! 

Thank you for your nice feedback. I did not modify the 3d viewer.

Do you have friends who have Apollo Standalone or Apollo A6000 (with ApolloOS)?
I would like to know if the program runs on the Apollo system.

The U177 clock input (pin 9) should always have an AC waveform on it, so your DC meter will be trying to read the average voltage.  I can't say if 0.5V is normal or not, as of course you need an oscilloscope to actually see what's happening.  An AC waveform with an average of 0.5V and 0.5V DC will measure the same on a multimeter, you won't be able to see the difference between the two.  The meter should display some kind of AC voltage if there is a clock waveform present, though what's displayed will depend if the meter shows a true RMS reading or not.  You really need the correct tools to diagnose this kind of problem at this level, it's like trying to explain how to change a wheel on a car using a pair of pliers because you don't have a wheel brace

I wrote this RTC repair guide a long time ago, you could follow the continuity testing parts:

If U891 (in the fast memory interface) has been subject to corrosion, it would be worth removing that to see if the system starts booting or not.  Though there won't be any fast memory present.

Failing that, I do component level repairs if you want to send the main board to NZ.  Contact me for an estimate:
