Re: 720k Floppies with Windows 10 and a USB Floppy drive.

Just to be clear, some (including some new-ish) USB drives support 720k but not all of them.
All of them support 1.4M.

Also, the motors in them will not always turn slightly stiff disks fast enough for it to access data on the disk.

Re: Atari 1040 STf Monitor alternatives?

Any TV or TV frequency monitor that has analogue RGB inputs (such as SCART supporting RGB) should be able to display the Atari low and medium resolution modes. If you have a VGA monitor that can display TV frequency signals (horizontal frequency of 15625Hz and vertical frequency of 50Hz) then it may...

Re: Recapping an ST board - is it worth?

Electrolytic capacitors have a limited life. The manufacturers rate them at a specified number of hours when run at their rated maximum working temperature (often 85C, longer life types are rated for 105C). How long they actually last is variable, as it depends on a number of factors. The main reaso...

Re: 6 chip TOS

Get a piece of card. Write a story on it that takes up at least a few paragraphs. That's how the CPU sees it in memory. Now cut the card in half so you have left and right pieces of equal size. That's how the data is stored in a two ROM configuration. This is the low byte and high byte data (as the ...

Hi Winfryd You've got some lifted and damaged tracks and pads. I can see some in the photo of the underside of the board: IMG_7028.JPG The damage I can see is indicated by the red coloured arrows.

Re: Found an LCD monitor that works

Here I am talking about using the high-res. monochrome mode. With LCD monitors, it appears to depend on how tolerant the design of circuitry is to out of specification VGA signals. This applies also to the more complex CRT monitors. Some years ago when I tried a number of my ST's with the variety of...

Re: Vertical bars on screen

It is always a good idea to visually check the board for any problems. Pay particular attention to the more fragile components like the crystals. Sometimes socketed DIL ICs move slightly in their sockets. And in doing so, the electrical contact between the pins and the contacts in the socket becomes...

Re: issues with ROM port of the TT

Do you have a multimeter? Have you tested the +5V supply voltage? If the +5V output from the PSU is a little low, the machine may work correctly, but if it has many expansions and peripherals connected, by the time the +5V gets to some of those expansions and peripherals, it may drop a little to far...

On the subject of batteries and cells. All PCB mounting NiCad types used for memory backup or for RTC chips should be renewed every FIVE years. This is recommended by the battery manufacturers. Non-rechargeable Lithium 3V 'coin' cells (used for memory backup) normally have a life of around ten years...

Re: Atari 520 ST not reorganize floppy drive

When you power on an Atari ST, the OS tries to find a boot file on an attached floppy drive. After a while if it can't find a boot file, it will start the GEM Desktop. If the OS can't detect a floppy disk drive, it does not bother looking for a boot file and goes straight to the desktop. Unmodified ...

Re: Trolls in the Atari-Forum.

With FPGA type systems, they kind of fall into a big grey area. As they don't fully fit into any forum for 1980s or 1990s computers. But most were developed based on the core hardware of a real 1980s or 1990s computer. A FPGA is not an emulator. The logic gates in the FPGA chip are just configured e...

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

The regulated rail is the 5V output. So it's this that should be loaded. I suggest 6V motorcycle lamps for use as test loads. You don't have to load the PSU anywhere near maximum for a basic test. A 5 to 10W lamp (or combination) should do. Until the 5V line is working, don't worry about the other o...

Re: Atari ST floppy drives and their limitations

Yes, all 80 track 3.5" drives are, err, designed for 80 tracks...

Some can manage 81, 82, 83 or if you are really lucky, 84. But all that is happening, is you are taking advantage of an engineering tolerance.

The U.K. electronics chain and supplier, Maplin Electronics is now in administration.

Maplin are still trading as normal, as the administrators are trying to sell it as a going concern.
