How to install TSP under Mac OS

REQUIRES

If you are running TSP on a 68K Mac then it needs to have an fpu. If it doesn't, then you may be able to use a shareware fpu emulator. You can find one at Shareware.com. Please note that Macs using the 68LC040 chip can not runTSP (list of these models). All PowerMac models are able to run TSP without problems.

TO INSTALL

Insert the TSP disk into your disk drive. Double click on the TSP disk icon, and drag the TSP 4.3/PowerMac TSP 4.3 file to your hard disk. Double click on the .sea file to decompress the folder.

RUNNING TSP
 

Double-click on the TSP icon to start TSP. The screen will clear and TSP 4.3 will appear in the title bar of a scrollable output window. If you get an "insufficient memory" message under System 7 or Multifinder, TSP's memory allocation may be improperly sized. You can fix this by follwing these steps:

• select the TSP icon
• select Get Info from the File menu (or type command-I)
• Under "Memory Requirements" near the bottom of the dialog box you will see a box labeled "Preferred Size" which should read 4096. Increase the number there by 500 or so.

TSP should then launch properly. You can further fine-tune the memory number if desired - see fine-tuning performance below.

Once TSP finishes loading, a prompt will be given:

Select batch input file [or hit Cancel for interactive]:

followed by a list of text files in TSP's folder which can be selected for batch operation. Click on the Cancel box to run TSP interactively. (See the TSP User's Guide for more information on using TSP in batch and interactive modes.

FINE-TUNING PERFORMANCE

In general more memory will mean better performance, especially if you are using large datasets. Be careful, though, if you are using RAM Doubler or virtual memory. If you increase TSP's memory allocation to the point that your Mac has to use virtual memory to run, then performance will degrade dramatically. In general, if TSP is the only program you have open on your Mac, follow this rule:

TSP's memory allocation = (total physical RAM) - (system software memory partition + 1)

So if you have 12mb of real RAM, and your system software takes up 3,572k (3.5mb), then you can safely allow TSP 12 - (3.5 + 1) or 8.5mb of RAM. You can find out your Mac's total physical RAM and amount of RAM taken up by system software by selecting About This Macintosh... from the Apple menu.

Allowing an extra megabyte helps prevent virtual memory from being triggered and system crashes. If you tend to use TSP with other programs open at the same time then you shoud allow RAM for them as well.
