OR there may be a spare U4 in the read write slot of the UCM?

sorry fella, i have no idea what you\'re talking about? 
but here is a photo of my ucm.

The sockets are empty. The early ucms did not come with spare eeproms

[theshepherdmatt]

I dont suppose you have a spare MPU laying around that you would like to sell do you? I know laser sell them but I\'d rather get a second hand one as I still don\'t know if my PCB actually works?

[slychiu]

I thought you managed to upgrade your mpu to version 7? 

[theshepherdmatt]

Yes I did, but cannot connect to UCM as I don\'t have login codes. I\'d like to wipe the MPU and start again but with the login it\'s just not happening..

[theshepherdmatt]

Also I wanted to try and extract the old program files from the old UCM, but again it won\'t work without the login/engineer code. Being a security system there doesn\'t seem to be a \'back door\' way in but that\'s to be expected.

[slychiu]

I don\'t know if you mean the u4 eeprom or the mpuThe firmware is in the mpu  If you have upgraded to version 7 then you don\'t need a new one. The program configuration is in the u4 eeprom. If you have lost the engineer code then you need a new u4, not an mpu 

[theshepherdmatt]

oh? thats good news..
it looks like my setup doesn\'t even have a U4?

[slychiu]

It is not clear from the photo if the U4 Socket is emoty or there is an IC inserted
