Properly testing a C128

[Major_Tom_coming_home]

I just received a C128 I purchased from Ebay and was wondering what kind of testing I can do to confirm it is fully functional. So far I have loaded a cartridge game and played with a joystick. Sound, picture, cartridge port, and joystick port are good. Booted to basic and tested all buttons and they are good. I don't gave any disk drives or other peripherals yet. While I'm waiting for an SD2IEC is there anything else I can check out? Thanks!

You will have a hard time testing much with no way to load software. About the best you can do is what you have done, but, without a cartridge so you can boot to the 128 mode. Will your monitor support the 80 column mode? You should test that too. You can't use them, but did you get the disk set that came with the C-128? That included the CP/M software.

You will discover how much you need a floppy drive, even with the SD device. The 1571 is an excellent drive - maybe the best Commodore ever made. Goes well with this machine.
