m5126 does not want system 7

[fidelware]

Hello, I am a new owner of an m5126, but with problems, it has 4 MB of RAM, it worked with OS 6.08 but does not support OS 7, and 5 keys do not work. any suggestions? 1000 thanks

For the keys, it’s likely a matter of thoroughly cleaning the inner contacts: desoldering, disassembling and cleaning each single switch.
As for the OS, 4 Mb are sufficient for installing OS 7, hard to tell why you are not able to install it.
