6300 Memory upgrade

[Richard Gopstein]

  A friend has an ATT 6300 with one floppy drive and one 10M
hard disk purchased about a year ago.  The system came with 256K
RAM on the motherboard, and he is interested in upgrading the
system to 640K.  Unfortunately, he thinks that all of the existing
chips (64K)? are soldered directly to the motherboard.  Did they
really do this?  If so, what are his options?

Thanks.
