SVCS is a non-profit corporation dedicated to mutual assistance and 
information exchange concerning the IBM PC, compatible computers, and related 
software.  We hold a meeting of the general membership each month. We also 
have monthly meetings of various special interests groups (SIGs). Some of our 
current SIGs are the NEW USERS SIG, TELECOM SIG, BUSINESS/FINANCIAL SIG, FORTH
SIG, GRAPHICS SIG, SOFTWARE TOOLS SIG, and SOFTWARE LIBRARY SIG.  A newsletter
 of about 20 pages with a circulation of 800 is mailed to members each month.

We maintain a growing software library (over 70 diskettes as of June 1984) of 
public domain and non-commercial software. Both a catalog booklet and 
a diskette resident catalog of the contents of our library is available. 
The diskette resident catalog has an interactive menu-driven program for 
automated interrogation of a categorized data base. Write or call to request a 
membership information packet and software order forms.
