I don't think useful is the most accurate term for this old Macs. I think it's more a question of authenticity. To have the configuration of the first Mac.

So maybe the ROM I bought was not working 😬 Ok I will check also the connections, thanks for your great knowledge sharing.

Very interesting Builder68! So what your are saying is that every 512k / 512ke LB can be transformed back to a 128k LB ? (I already tried to transform a 512ke(not exactly sure which version, but surly 128K size ROM and 800K drives) board into a 512K original LB, just by replacing the ROM and...

And the other bad news is: I think you have MacPlus Rom's (this match also to run 1MB of RAM), but the MacPlus Rom's don't work on an original 512k logic board (the first 512k logic board is more valuable) but only on 512ke or later.

I think your Mac was updated twice, one time by replacing the logic board 128k to a logic board 512k (blue 512k label) and then later with this extension cart to 1mb. So I think you cannot "go back" to a 128k Mac logic board (without changing the whole board), because this was never a 128k...

On my side I could adjust the sensor position and resolve my zero track issue. I'm so happy 😊, my 400k floppy drive is 100% working now.

On my 400K floppy drive I could lubricate the blocked stepper motor actuator, but now the motor don't stop and tries to push the gear to far. Does anyone have an idea where is the sensor to stop it ?

A long time has passed. Were you able to finish the game before your 50th birthday 😊 ?
