Ok sportsfans, here it is. I've got this old Powerbook 165 it's a 4/80 config. OS 7.1  14.4 ext modem Netscam 2.0 . Now I've set my vram at about 10. I hear that this vram stuff will really slow things down considerably with respect to the interenet. I do know that the rig is painfully slow now. MY question is, if I add 4meg real ram, turn off vram, (is 8 enough for 7.1 and 2.0?) add a 28.8 modem, what will be the net speed increase in real time page loading? Is this worth the expense? gee-tanx

Your connection to the internet is determined by the quality of the telephone connection and the modem with the slowest speed (your isp or you). The computer itself is a lot faster than any connection you can make. For instance localtalk is approx 128 KB/sec, while your modem would be 28.8 KB/sec.

The computer slows down because it has to access the hard drive when you run the program + access the hard drive to download the text and images to.

To answer your question: Increasing your memory and turning your VRAM of will increase the speed of your mac. But the largest increase in speed you will find when you use a 28.8 Modem compared to the 14.4, but only if your dail-up connection supports it.

Regarding your question is it worth the expense?. Memory is still a lot cheaper than a new computer. Instead of the 28.8 you may want to purchase a 36.6 or 56K. Just in case you will buy a new computer in the near future, then you won't have to purchase a new modem

Good luck

This may be hard to predict, but I'm still wondering what percentage speed increase I will achive. If it' only going to be in the 30% range then thats not worth it. 2x faster would be a worthwile improvement. I realize the system will be faster, HOW MUCH? Also, what would be the limit of the port, to process the incoming data? At what speed does bottle necking occur, this thing certainly could'nt take advantage of a 56k modem, could it?  One things for sure, If I put money into this thing, I wont be buying another puter anytime soon, If Im going to do that, now's the time? How much faster would a 520 8meg system be?

Thanx

Let me use an analogy:

If you buy a new car which is twice as fast as your old car, would you be able to drive twice as fast?

Yes, no and maybe. Sunday morning at 4 AM you will be able to drive twice as fast. Friday at 6 PM no way.

The same is valid for your modem. If you are the only one connecting to your ISP and the telephone connection is clear you will be twice as fast. But your speed is not just detemined by the equipment you use, it is also determined by everything else.

Buying a 28.8 modem will double the speed of your connection most of the time. I am using a 33.6 modem and it connects to the ISP at 28.8 most of the time (so I have no advantage over a 28.8 modem). Not that many ISP are supporting a 56k modem yet, and with the quality of most telephone lines you will not connect at 56K. But you also need to look at the (near) future. As more ISP's buy 56K modems and telephone wire are replaced by high speed digital circuits, things may be quite different next year.

I hope this is answering most of your questions, buying computer equipment is a risky and unsatisfying job. Next week they will have a better computer with more gadgets and cheaper than what they have today. I advise people to stay one step behind the hipe and buy last weeks model. Not the fastest but much cheaper and then you will save so much money you can buy another computer in 2 years, which of course will be faster and blah blah blah compared to the fastest model today

I rambling, have fun
