OK, here's the deal... I plan on purchasing a TT when/if they ever materialize, but in the meantime, I would like to upgrade my existing ST system without having to buy a new Mega. I have a 4 year old Atari 520 ST (not one of the old trouble-making originals with the bad power supply and first-off-the-assembly-line revision on the motherboard...this was purchesed during the last half of 1986, and has the second revision motherboard -- revision B, I think? - it's been a few years since I opened it up.) Anyhow, I piggybacked another half a meg worth of chips on top of the originals shortly after purchase...and there she sits: a 1 Meg ST...chugging along happily for nearly half a decade with no problems, no woes, no mishaps of any kind...now here comes Daddy, and he's gonna open 'er up again like so much oysters... I would like to bump the memory up to 2.5 Megs. Now, I know what has to be done....that's not the perpose of this inquiry...the question I put forth to y'all is: *should* it be done? Given the history and age of my machine, will it survive? Will its power supply be able to handle the additional RAM? Has anyone had any problems with older machines and power supply problems to greater thann 1 Meg worth of chips? Any response is welcome. e-mail it to me below, or, if you think its benificial information for the community in general, just post it...but a quick response is required, I have an itchy soldering finger...
