Hi all, hi IC,
Have some questions about ACA1234.
I recently got A1200 gifted from a friend of mine. Back in a days I had A500 but since 1990 I did not have Amiga any more.
My main purpose for this Amiga would be to play the games with my 8yo son (we are playing C64 games now on the Ultimate64, so I want him to feel the "upgrade" :)).
I was thinking of getting memory expansion only as I see it is a requirement for WHDL and it allows full use of 2MB chip ram and also increases the speed of A1200 ca. 2,3x.
But I do not know anything about games that came after 1990 and I see some suggestions on forums that the accelerator, although not a must have, really helps with some titles that were made after 1990.
So I am thinking of buying ACA1234 (also with RTC module and Indivision AGA MK3 for which I have some questions also but will post in the appropriate forum). I checked what is available from the accelerators on the market today and think that ACA1234 is the way to go.
So my questions are:
1. My understanding is that if I would purchase 25Mhz accelerator version, I would get a chip that is guarantied to do 25Hz, but that the same chip would maybe be able to go to 33, 40 or even 50MHz. But it is not guaranteed? Is that correct?
2. Is more than 25MHz on A1234 accelerator really necessary for games? I mean, if it would go to more MHz I would be inclined to buy a license later (as the initial investment for accelerator and mk3 is somehow high, at least for me).
3. If I understood correctly, I would not need to flash ROM chips anymore as I would just need to put ROM images on the card as they are released?
4. In the "stealth mode", does amiga have access to any portion of the ACA1234 memory or everything is disabled?
Thank you very much for your support in advance.
PS. I already had A1200 recapped by the people that do that stuff. Also, they corrected some timing issues on the board (they said it is a common issue on the board and is usually done with the service/recap). The new power supply I got "Amiga PSU Boost" from c64psu (not sure how good it is, but was recommended from my local retro group and seems to be working OK)
