LocalTalk PC Card: How To Free Memory To Print

We installed a LocalTalk PC card on a 386 AT clone with 1MB RAM. We use this PC to download stock quotations. The company uses Macintosh SE/30 and IIci systems for everything else. We want the 386 AT to print its stock data to the LaserWriter IINT.

When we try this, we get a message saying we don't have enough memory. We are running MS-DOS, LocalTalk PC software, and the program for the financial service. How can we print reports to the LaserWriter?
There are several ways to minimize the RAM allocations in an MS-DOS machine, which may free up enough space to run all of the applications at once. You may try reducing the number of buffers allocated to DOS, for instance.

If you configure AppleShare PC for print services only, you can expect it to take up 62K to 90K of base RAM. Because AppleShare PC must reside in the 0K to 640K range, you may free enough RAM for everything, if you can configure other portions of the operating system to run in the 640K to 1MB range.

We advise you to minimize existing RAM allocations first and re-install AppleShare PC with the minimum services. Then, if that doesn't work, start moving applications into higher memory.
