I went for the 2MB ram upgrade, a 40MB disk, and clock battery kit, to the tune of $1550 parts and labor. The previous configuration was the wimpy and nearly useless .5MB ram, 10MB disk, along with "epoch clock syndrome" :-) The people I dealt with (Andrew and Cathy Cohen) are professional, courteous, and knowledgeable. They deserve all the business the 7300 user community can give them. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Well, I've taken the plunge! I've had my 512k motherboard upgraded to 2 Meg by the Amperfax (sp?) folks in Florida. First, let me tell you about the the company. This has got to be one of the most professional outfits I've ever done business with. When you are ready to order the upgrade, they will send you a simple agreement (contract) to tell you about what is gonna happen. When you are about to ship your parts (I shipped only the motherboard, the whole machine is ok too) they ask that you call them on the phone and tell them when to expect the shipment. They call you when the shipment arrives! Then, they call you when the conversion is complete and tell you when to expect the shipment back. I sent my motherboard on Monday, they got it on Wed, converted it, and shipped it the same day. I got it back Friday. Now for the preformance... I had a 512k motherboard and a 512k expansion board before, and now have 2 Meg with no expansion board. I took a few stopwatch tests of typical tasks and heavy duty 'compute bound' tasks before I shipped it off to compare with. On the average, the speed of the typical tasks were increased only slightly... 5-7%. However, the increase in performance on big tasks (like a 'make' on large source code files) were more like 15-20%. The real increases came in multiuser and multitasking situtations... typically 50-70%. One of the increases that puzzled me was the apparent refresh rate of the screen! I'm not sure how the two are related, but it appears that things are happening faster on the console. The bottom line: If you use your machine for code development (like I do) or have multiuser/multitasking situations, then the upgrade is a bargain. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: PLEASE TELL AMPERFAX WHERE YOU GOT THIS INFORMATION (NEWSNET) !!!!!! ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: AN INEXPENSIVE RAM UPGRADE FOR YOUR 7300 OR 3B1!! +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Ok, here is how to get more information: Call or write Andrew Cohen of Amperfax and tell him WHERE YOU SAW THIS INFO!! This is very important. Amperfax is trying to find the best way of contacting 7300 and 3B1 owners, and they must know how you found out about their company!
