In the settings of COM1 in the Device Manager, Windows Me offers 921.600 bps as fastest transfer speed. I also installed W32Tran8x v4.1 and the DriverLINX Port I/O driver (Port95NT.exe). This link cable is also called $4 serial link and is compatible with the black link cable by TI.Īfter installing a supported display driver ( VBEMP 9x), the system became much faster and better looking.

After assembly, there were some random missing lines on the display that changed position upon pressing buttons or the case. I don’t know what it was, but probably not caused by leaking batteries. On the contacts of the batteries was a greasy substance and dirt that could be removed easily. Also, I’ll have to look inside to check if the backup battery has leaked in all those years.
