Are any of the ICs in this machine in PLCC sockets? There is an inherent problem with those, the constant 'spring' pressure on the insides of the sockets from the IC pins tends to bow the sides of the sockets slightly outwards over a long time, leading to eventual loss of reliable contact between th...

Anyone else noticed this? https://sites.google.com/view/rastari While it is undeniably useful to have Hatari packaged as a ready made Raspberry Pi SD card image I'm not sure it gives quite enough credit to the authors of Hatari. This was brought to my attention by an article in the December 2020 'Li...

A good while ago the ADscsi interface of my Power Computing HDD finally died, but it was the interface, not the drive, which had failed. I did what you are planning to do, bought a PC SCSI card and put it in a desktop computer running Linux, connected the drive from the Atari HDD to it as a secondar...

Apologies if you already know this, but you can't use a VGA monitor as a substitute Atari colour monitor. The ST does output RGB colour but it does so at standard television frame rates which most VGA monitors will not work down to. You can however use a VGA monitor as a substitute Atari MONO monito...

You've obviously done your research. My STe also has the "good" DMA IC and I have never had problems using the UltraSatan with it. There are far ranging arguments over whether the 'bad' DMA IC is solely responsible for the DMA problems which some people experience on the STe. More likely it is a com...

If it comes with a pre-figured card then surely it already has the ICD PRO driver on it and is ready just to boot. That was certainly the case with the Ultrasatan + card I bought from Lotharek a couple of years ago. If you have the means to do so, make an image backup of the card before you use it b...

If the encryption algorithm the creators picked is any good it will be a lot more complicated than just send a certain number to the dongle, expect to see a certain number come back. It does happen, I remember back in the days of Analogue 'Sky' TV in the UK where someone had figured out the correct ...

Oh Thank God you're back... Thanks for doing whatever it took to get the site back up.

With due acknowledgement to the author of the original diagram, I have added some detail to it which may make things clearer. Note it doesn't actually matter which three of the four elements of U2 you use or in which order, but I have put specific pin numbers into that part of the diagram if you jus...

I just had a look around and I can't find one off-hand in any of the usual places, which is surprising because the need for such a circuit must arise quite often. Maybe others who are better at google-fu can do better than I did. I don't have 'Fritzing' but if you post the circuit you have produced ...

Just to be clear, you are trying to use an RGB SCART source which is NOT an Atari computer with the Atari monitor, which currently has a 13-DIn plug on the end of its video connection lead? The main problem is the difference between sync arrangements - SCART RGB uses composite sync - often in the fo...

Yes, standard install of currrent Raspbian distro, so using MIDI as a 'native' Linux device, rather than through PortMidi.

Your sig doesn't say where you are. If the TV you are currently using has a SCART socket it will be a worthwhile improvement to make or purchase an RGB lead for the ST so you can connect it that way - much cleaner picture, especially on a CRT TV.

On the original STs, games often booted from disc and once running there was no way to get out of the game except by resetting the machine. So Hatari is very realistic in that sense. To reset the simulated ST provided by Hatari, hit F12 to call up the Hatari menu, and on the first screen you see a '...

Once more onto the beach :) The data bus from the DMA controller to the FDD controller and from the DMA controller to the HDD port is one and the same, so one possibility is that the buffers which allow the HDD signals onto this bus are enabled / transparent when they should not be, so when you conn...

Quite well, that's what I usually run Cubase 2 into when running Hatari under Linux. I recently used a basic USB-5-DIn midi converter lead with a Raspberry Pi 4 running Cubase 2 under Hatari for about 6-7 hours, and it literally never missed a beat.

A friend of mine used to say that when an intermittent fault mysteriously cured itself it had gone 'Mittent'. Let's hope yours stays Mittent, because intermittent ones are the worst ones. Unless you find a solid gold cause for the problem (unsoldered pin, or something like that) you can never be tru...

Thanks Eero, Long story cut short, after swapping to SDL 1.2, the trackpad cursor overspeed problem in fullscreen mode is the same and requires the same divide-by-four fix to get the trackpad cursor down to usable speed. SDL2 and SDL1.2 are both the most recent versions, compiled from source direct ...

An old CDROM drive (with an adapter) works well too Not in this case, I presume you read that the PSU in question was originally producing gross overvoltage on both rails? If it is still doing so after replacement of the failed resistor then any 'smart' load, like a CD-ROM drive or HDD would be ins...

OK then, give it a go and see what output voltages it delivers (a) with no load and (b) with a lamp load. Is this one of the versions which has an adjustment preset on it, or one of the ones where the 'adjustment' is set by fixed resistors?

12.04 certainly was ancient but actually it, and Hatari running under it, were working really well, partly because the age of the distro was a good match for the age of the hardware and therefore ran beautifully on it. Unfortunately I suffered corruption of the OS and, faced with reinstallation, dec...

I think we've been asked this before. Personally I prefer analogue / CRT scopes for general work and storage scopes only where I need them, but that's just me, others may swear by digital. I've just had a look around and the prices of what would have been considered basic 'bread and butter' analogue...

If you have replaced the resistor, yes, test it with loads (but definitely not in an ST or STe yet). What are you using for loads for the +5V and +12V? chunky resistors? Light bulbs?

I've just attempted to remove the above trackpad movement mod and recompile Hatari with the --disable-sdl2 switch to see if this mouse overspeed problem is present in SDL1.2, and although the whole process went without error, when I run Hatari from the command line as I usually do, it is showing me ...

I think I'll write that on my circuit diagram, quite a deadly fault, in terms of the damage it could do to the ST, STe.
