Re: Missing TOS ROMs?

IIRC, tos 2.05 does not show Atari Logo and memory test bars when it is testing ram. I tested several 2.05 images (US,Sweden, Italy, German) and can confirm - all of them behave the same way - no Atari logo and memory test messages at startup. BTW, I saw pictures of your ship :thumbs: I just update...

Yes, it helps a lot, so maybe most of the time is taken by RAM test (and I have it 14 M in STeem) !

Re: Missing TOS ROMs?

Yup - as I stated in my post, tested with STeem (Standard ST, 4MB, UK Keyboard layout). Try running it up with no disk image first. This takes ages to boot as TOS 2.05 does a full RAM test but there is no screen output (Atari Logo, progress bar etc) during this stage. So use the Fast Forward button...

Hi Dima, just test it with the Czech TOS and everything works OK. Hi, Jan, Czech TOS ?! It's not on my collection. Please upload ! Did you set the buffer size? What is the output from rommix?

rommix takes as parameter control file which describes what to do. For example rommix.ttp split.mix Still no success. I made the merge.mix file with following parameters: load toshi.bin 0 128k all -> 0 high load toslo.bin 0 128k all -> 0 low save tos_205.img 256k <- 0 all It creates some image, but...

Re: Missing TOS ROMs?

You can use ROMMIX utility from the Pinatubo package. It can split ROM files into any number of parts. And it can also merge the parts together. You can find it here: http://www.ccac.rwth-aachen.de/~michaels/index.php/atari Sorry I couldn't understand how to work with ROMMIX. Could you please tell ...

Re: STE 1040 is not running

Dear Simbo !

Could you give a bit more detailed instruction - how can we check clock, DMA and others - where to measure by oscilloscope and what we should get if ic works ?

PS Interesting thing - when I put new RAM - 4 Mb - right floppy lamp start to shine, but system is still not loading

Re: STE 1040 is not running

found one friend in my city with STE. Visited him today to test some elements. Unlucky he has another revision, so only RAM and TOS chips were able to test - working OK, while his TOS inserted in my STE didn;t solve the problem. Going to visit another man having oscilloscope. Simbo, could you please...

Re: STE 1040 is not running

Seems that U210 is OK.

Pins 1 & 3 have low, while pins 2 & 4 are high.
If I hold pressed reset button 1 & 3 have high, and 2 & 4 have low.
As I understood it is like should be.

Next steps, please ?

avtandil what electrical test equipment do you have access to? :?: In order of preference the following is useful for fault finding digital circuits: * Oscilloscope :idea: - My friend have the one, but it will be a big story to deliver STE to him, as he don't like to borrow... * Logic Probe :idea: ...

Re: STE 1040 is not running

Strange thing - my PM to Simbo is still in Outbox folder for the second day. Simbo, did you get it ?

In short - I tested to remove and put back all ic you advised - no result.

I need a bit more explanation - what points can I test with multimeter and how to do this .
