Re: Is it possible to generate a 16:9 picture out of Atari

No, I said that there is no AR related info in analog video signals. It is on monitor. And user - and latest is most important :D

Re: Is it possible to generate a 16:9 picture out of Atari

There is no general rule. And you asking about unspecified monitor, attached to some converter of questionable quality - which produces some really weird resolution(s). Look all possible settings, and if can set it, set. That's all.

Re: Is it possible to generate a 16:9 picture out of Atari

Nothing defines AR of some old type PAL or NTSC or RGB, and RGB is with same scan frequencies as PAL and NTSC . Even on classic monitors it was different with 50 Hz of PAL and 60 Hz of NTSC - because NTSC has less vertical lines. But user could set AR with controls at back side of monitor - mostly h...

Re: no-software internal RTC

I traced it down, and looked in literature - ProfiBuch has all needed except TOS code . So, time, date goes to, comes from IKBD chip in packed BCD format. Every value is 1 byte - year, month, day, hours, minutes, secs. - total 6 bytes. And that means too, that max year span is 100 years - 0 to 99 . ...

Re: TOS after 32 years - what could be done better ?

And something really hard to understand and trace: storing year in IKBD chip, and how it is handled. I seen this problem 10 years ago, and made little program what overrides it somehow. That works not well in TOS 2.06, as I seen it today, probably because TOS code for reading IKBD date is little dif...

Re: no-software internal RTC

I've done some research. Keyboard communicates with ST using a simple async serial protocol with baud rate of 7812 bps. Single bytes are being sent one by one with a pause of 4.5ms between each. Setting a clock is done by sending 0x1B followed by YY MM DD hh mm ss. Date is sent as hex, so for month...

Re: NEC Multisync LCD

I looked about those NEC monitors couple years ago in Hungary. Very rare here. Found only 1, not close. And they asked too much for. What is btw. bad habbit here, in second hand shops too - some complete average, 17 inch, about 10 years old LCD costs 25-30 Euros. So, that NEC would cost me about 100...

Re: Game recommendations please

I will try to list here some games which are considered as better on ST than on Amiga, or no Amiga v. Not in some particular order, but one surely stands out: Potsworth & Co. http://atari.8bitchip.info/ASTGA/P/potswco.php 6 games in one, good scroll ...
