Luckily the battery leak was not too bad, just some on one of the battery terminals, and
the pcb and wires was not affected.
I just removed the dead NiCd for now, the printer works anyway with just the power supply as you said.
Will the cassette deck work also without NiCd installed?
Maybe i will install some new NiCd someday

The tape unit should work fine with the power supply and without batteries. If you can't CSAVE and CLOAD back, then it's probably the belt slipping. When loading with CLOAD, the high-pitch sound should be stable, not fluctuate.

Note that the CE-125 audio jack port on the side is for loading from an external tape. I've used this with PocketTools to load programs from a PC or Mac via the headphone output, but note:
- The CE-125 works better with mono audio jack plugs, but sometimes stereo input plugs will work. If a stereo plug does not work, switching to mono audio jack plugs may help.
- PocketTools bin2wav --level=2 appears to work much better, so this option is important when bin2wav may fail to produce adequate sound levels with some desktop or laptop computers.
- PocketTools bin2wav --device=125 should help if the audio levels are not high enough for the signal to be picked up by the PC-1262.

You can find the original PC-1250/PC-1251/TRS-80 PC-3 Applications software that came with the CE-125 here:

The PC-1250 Application Software program examples (20 BASIC programs) work with the PC-1262. Or you could type them in, from the Applications book, on the tiny keyboard

PS. I found a way to create a quality PDF of the 300 page PC-1260/PC-1261 manual. This is not easy to do and will take some time to capture each page. Stay tuned.
