Yes, I have tried with three different batteries (all in mint state) and nothing new. I bought this morning a contact cleaner spray, I will use it over the chip sockets... is my last idea. --- In gsp-2101@yahoogroups.com, M M <strategy400@...> wrote: > > > Good suggestion there (the battery). I had to replace the battery in my TSR24S recently (bascially the same as a 2101 with no preamp section) and that cured it. Had to do a hard reset after changing the battery.Before the battery change it would only scroll the credits and then if I tried to change programs it would hang and corrupt chars similar to yours.

I think it must be a bad contact somewherenear the Z80, SRAM and firmware chips, because if I touch over thesechips with a finger and bend a little the PCB board, the unit hangs.It can't be a corrupted settings issue because sometimes the unitshows strange chars immediately after power on.
