Re: The strange case of the non-running games.

XCONTROL for sure causes RANDOM crashes on Petari's HAGA games. One time they will work, other time they'll freeze, and yet another they will crash with 2 or 4 bombs. So I'm sure XCONTROL can't be loaded in order to play HAGA games. Klaz's HDD conversions don't have such problems (but there is not m...

Re: The strange case of the non-running games.

Petari's loader (called HAGA) doesn't like to have any resident programs in memory. Sometimes it will work, other time it will crash. For me the ultimate solution was to use X-BOOT with a "clean" config for Petari's games. There can't be any accessories, nor AUTO programs it barely tolerates ICD HDD...

Re: Replacement PSU for STf/STe

I have found even a better one - Mean Well RD-50A. This is only +5V/+12V (without the -12V line) switchmode PSU. It's not on the photo, but I've already added the PE wire:

Re: 520ST small model w/ no floppy / general advice

AFAIK you can use a Gotek as an external drive, but I would suggest you ask around the forum to see if anybody else has done this with an original 520. I have Gotek (HxC USB) in the external enclosure, I tried it on the 520ST and it works fine. Using Gotek in Atari ST DD interface mode you can use ...

Re: Jan Beta Mega ST

Keyboard is not original, I've replaced the LEDs in it, because the case I had has the red filters in it (and green LED + red filter = no go) and actually the board and top case are probably an original pair (bottom part is not), but the original floppy is dead, and I got it without the keyboard (th...

Re: PC mouse refresh rate

That's not completely true that LCD has no flickering. It has, and it always had. In a huge simplification pixel transparency (brightness) is proportional to voltage (charge) applied to that pixel (cell). But due to the nature of the LCD displays the average cell charge have to be 0, to avoid LCD de...

Re: Jan Beta Mega ST

As I've promised - I've tried, and it fits: https://obrazki.elektroda.pl/9182226600_1541442719_thumb.jpg The unloaded 12V is slightly too high (over 13V), but I don't care as it is not used anywhere on the board (it is only for the FDD motor). It fits really tight, but without any modifications, but...

Re: Jan Beta Mega ST

If I've managed to fit RT-65B (but without it's case), so the smaller RD-50A should easily fit... I've already ordered it and I'll check this soon. I've ordered from a local distributor (TME.EU), and there was almost no difference in price with Aliexpress :/ I've paid ~20€ incl. VAT & PP. Quite expe...

Re: Desolder braid

You should really forget about desoldering braid and desoldering pumps and get into the desoldering station, like ZD-915. Comfort of working with this is incomparable. For cleaning the pads you may still use the braid, together with RMA7 gel flux.

Re: 1040 STF showing occasional rogue pixels

If it would be the MMU related problem, the stripes would be on a whole screen. As they are only on some region, it is more likely that the issue is with the RAM itself.
