thanx - yes, but I think the primary problem is a corruted sd (mico sd in adapter) card. I reinstalled piCore on another micro sd card and it worked fine. I was also able to install several extensions. Then after a while, when I tried to install an additional extension, the cursor freezes and no CTRL-ALT-F1 works either.
After shut down and boot I was able to install openssl,
Power supply and sd card is the #1 problem on Raspberry Pi. I am using a micro sd card with adapter now because I bougt the new B+ which uses micro sd instead of sd cards. So I can try and use it on the new Raspberry Pi also.
