- Hello to those in net-land. I seek your collective wisdom. I
- am writing to you from the Very Large Array (VLA) in west central
- New Mexico. The VLA is a radio astronomy observatory for
- scientific research. We use a Mac II (no letters) for the
- telescope operators to keep a log of each observing program and
- document our procedures. The Mac II has 8M of memory, using System
- 7.0.1 (TuneUp 1.1.1),an ethernet card, CPU = MC68020, FPU = 68881,
- and it has a math-coprocessor. Include also the fact that it has
- dual monitors and an external hard drive (80K, the internal is
- 40K). We run a network of 3 Macs at our main site and 3 Macs at
- our office building 50 miles away. Sorry about asking you to wade
- through the above, but hopefully it will give you sufficient
- information to answer my question.
- The telescope operators spend some 30% of their time at the
- Mac II running an observing log program using Excel 4.0. Using
- something besides Excel would probably require many hours of work,
- I rather not take the re-write route. Updating documentation is
- another chore and we use WordPerfect 2.1. They complain, validly I
- think, about having to turn their attention away from the array's
- performance to use the log program. Summed up, they want a faster
- machine. Now the dilemma.
- What should we do; upgrade, buy a new machine. My boss says
- that money will be a factor and that a factor of 2 speed increase
- is not worth it and to look for a factor of 5 or so. Please help
- me collect some ideas on what to do. I need some ideas of the
- amount of speed gained (I know, hard to determine and depends on
- what we use it for) and the cost.
- Thanks in advance for all your help. I'll summarize if there
- is sufficient interest. Please respond by e-mail.
