James,

I found in my basemsnt a short stack of 5 1/4" diskettes:

    VM/PC Service Aids
    VM/PC Control Program
    VM/PC CMS
    VM/PC Library (Backup diskette 01 -> 04)
    VM/PC ASCII Host Program Conversion Utility
    VM/PC Utilities

I also found some manuals:

    PC XT/370 Technical Reference
    PC XT/370 Guide to Operations
    PC/XT Hardware Maintenance and Service

Are these of any use/interest to you?

Ken
