Re: Hatari MIDI support

It would be interesting to see how accurate the timing can be on a Pi running Linux compared to an Atari. Unfortunately there are no professional Linux sequencers, so you're always better off with an Atari. My guess without trying it would be: Atari 1, Linux 0, simply because the Atari OS (that I a...

Jondi, tell us: -How you have the machine connected to your display.

Re: STE power supply problem / switches on and off constantly

For a basic test, I agree that any middling load will do, but as a (general) electronics repair technician for many years I have seen quite a few cases where an SMPSU would hold up its output until the load exceeded a certain percentage of its specified capability, and then collapse or oscillate off...

Re: STE power supply problem / switches on and off constantly

Disconnecting the power supply output from the ST motherboard and seeing if the output voltages are steady and normal is not an absolute test for any SMPSU because it is possible for one to output good voltages under no-load conditions but then collapse or oscillate under what should be permissible ...

Re: How much RAM in your Atari ST?

Back in the day 2.5Mb was quite common on STFs. I agree, this is one relatively common RAM size that the poll missed out. 512KB STs were often expanded by leaving the original 512KB of ram active but adding 2MB to that for a total of 2.5MB. My original 1986 520STFM is expanded in this way to 2.5MB....

Re: Can you solder surface mount? (new hardware)

Re: Atari SC1224 with stuck volume and brightness knobs

Be very careful if using a screwdriver in the slot to turn these, because the metal used in the shafts of these splined pots is very brittle. Bend the metal out, bend it back and it may very well shear off. Even if it doesn't, it is very difficult to get the two halves of the shaft perfectly back in...

Re: "Waving" RGB output - cause?

It does look like the Hsync is being slightly advanced and retarded at a slow sinusoidal rate. With everything being derived from crystal clocks it is hard to imagine how that could be. Sorry, I know that doesn't help much. Does this effect appear when an RF lead is used instead? How switched on is ...

Re: 1040 STE capacitors

I share your pain, I have cramped facilities here as well. As to size and voltage, you will typically find that (example) a modern 4700uF 35V capacitor will be about the same physical size as a 1980s 4700uF 12V or 16V capacitor. The main penalty for using a higher voltage capacitor than necessary is...

Re: 1040 STE capacitors

If you are recapping anything, generally the technique is to read the values off all the existing capacitors you see fitted and order replacements for them - same voltage (or a little bit higher is OK) and same value. The ones used in the high frequency parts of the power supply and on power supply ...

To definitely resolve whether this is an SDL problem or a Hatari problem, try installing SCUMMVM and a compatible game such as 'Beneath A Steel Sky' or 'Flight Of The Amazon Queen' - both available in the repos of most distros. In fact I think if you install either of those games they will install S...

No, I think both games were great but Speedball 2 has logical and worthwhile extra features compared to the original.

I would also say the same about Xenon 1 and 2, another duo of titles from the Bitmaps.
