Re: Atari STe SD card reader on the Extended Joystick Port

Great Idea,well done! I love the fact it's such a cheap solution and doesn't need the case to come off. I guess the downside is that you need to rely on the floppy to boot. EmuTOS has a SD card driver that can be easily adapted to new hardware. (In fact, it only took me a few hours to make it work ...

Re: NEW IDE Controller & TOS 2.06 board (with extras)

You can get TOS 2.06, IDE and USB(!) for the 520 STfm with the combination of Lightning ST and Cloudy: See the following links for more information: https://www.atari-forum.com/viewtopic.php?f=15&t=37225 https://www.atari-forum.com/viewtopic.php?f=15&t=37963&p=388528 http://wiki.newtosworld.de/index...

No answer from Lotharek so far regarding this. In any case I have added to the driver the option for the user to enable the overcurrent protection mode that for now is disabled by default. I had the opportunity to measure the available current myself on a NetUSBee (Lotharek version). OCP works -- o...

I realized that the characters of the extensions are replaced everytime with exact another symbol. Like missing a bit or taking it from another character set You're right about that.

PS: We will include Storm Disk software with the Storm ST: a reset-proof RAM disk optimized for use with the Storm ST. It's size is of course configurable. For example, with the Storm ST you could have 4 MB extra RAM in your ST for applications and 4 MB for the RAM disk (or any other split).

However, I'm not sure how compatible MiSTery is with EmuTOS (some earlier MiST versions had prob...

Re: TT FAQ: "Wait states off MCU msb (7) never set" diagnostics message => Harmless

As you are talking about the (ST-RAM) MCU: as soon as you populate an add-on ST-RAM board you've got two MCUs in your TT. Does it mean one is partly deactivated? Otherwise you would have two sets of registers at the same addresses. 8O Even though the documentation does not state explicitly that the...

Re: TT FAQ: "Wait states off MCU msb (7) never set" diagnostics message => Harmless

does it mean we can switch the ROM access from 200 to 120ns? If you had a Rev. F MCU, probably yes. But I don't believe this revision even exists. How do you indentify the revision? Most TTs have "C301225-001A" on the MCU, does this mean rev. A or one of the first two by National? For the test (of ...

Re: Atari STfm IDe enabled TOS 1.04 problem

Does TOS boot when you place the CPU directly in the relocator/riser shown on your photos?

My best guess would be a bad connection. Using a multimeter, check connectivity for each of the 64 CPU signals, from the actual pins of the CPU to the pins that go into the mainboard.
