Re: Homebrew Atari ST ?

Maybe a little bit off topic but for example here in Finland working real Atari St/STE s are becoming more and more hard to find. So if there is not going to be any re-production on St like for example c64 has had, in the future most workin st-compatible machines are probably some kind of fpga clone...

Re: Question about monitor and TOS...

Just to make sure, your machine does have to have a modulator to begin with for this mod to work, right? Yes, luma%chroma signals out from MC1377 chip. Of course there is a small risk damaging mobo, specially when desoldering components, those old mobos can be quite fragile. I have done that mod fo...

Re: Question about monitor and TOS...

Hi You can also get S-video signal out from your St with this mod: http://www.atari-forum.com/viewtopic.php?f=74&t=15728 , but you will loose tv- out signal . It´s not so hard to make as it seems to be when first time reading, second time with schematics and bare motherboard helps a lot...And then y...

Re: MMC cards - can they work in UltraSatan?

I hate to be a fun breaker but I looked closer at my mmc card...Top side of the card it says "multimediacard" but when i googled mmc: https://en.wikipedia.org/wiki/MultiMediaCard it seems to be a mmc plus-card which seems to be closer to Sd card than original MMC card regarding specs. So I have no i...

Re: MMC cards - can they work in UltraSatan?

Hi!
I have a satandisk and also 64mb MMC card (made by Nokia I believe) and it works ok. Actually it feels faster than my Sd cards, but it is smaller in capacity if it has anything to do with it. I know that this doesn´t directly answer to your question but maybe some help I guess...

Hi I have a 520 stfm with one meg memory and yesterday when I turned it on only thing that happened was high frequency "ticking" sound a bit like grasshopper sounds. :) It seems that the sound comes from power supply and none of the leds works and no picture on the monitor either.

Re: Satandisk problem

Hi

Many thanks for people helping with satandisk. It´s a bit of a mystery what really caused the problem, several possibilities crossed into my mind but at last it seems to work really fine and my Atari St is ready for Hd age :D

No, I haven´t, is there any other programs available than hddriver, for testing i mean. I remember reading of a hdd driver in a Superior menu disk, could it work for testing satandisk or is hddriver the only alternative :?:

Satandisk question

Hi
I'm building a satandisk, but got a problem with a component, 74lv125 so14 is a bit difficult to find. I was wondering if it is possible to use a 74hc125 or 74hct125 instead? Datasheets show that they are quite similar but not quite. Is this the end of my Satandisk project.... :roll:
