This is for those who would like to try out the WSPR QSO mode in WSJT7 but don't want to tie up a newer computer. I run Win98 on a 300 MHz IBM ThinkPad 380Z with a PII processor and found that the WSPR QSO mode works fine. The decode requires 100 sec but because the TX and RX cycle durations are each 120 sec there is sufficient time for the decoding process to take place as the TX cycle is engaged. I've been on 80 meters with KA8ECX, and we find that the WSPR QSO mode works perfectly with this minimal system.
