Riiiight I see, thanks Phipli. I have a very faint recollection of this. Perhaps there’s a failed nubus adaptor and bracket out there. 🙄

Thanks @Bolle!

Can anyone tell me what’s going on here? iisi with co processor nubus adaptor, the nubus card is a radius gs but it’s around 15mm short of the aperture in the case. Are some cards shorter or is it the nubus adaptor? thanks

Thanks @s_pupp, thats good to know, I’ll dig into the eeprom resetting and give it a go

Before I order the cells, has anyone had success with this? looks possible going through the threads but not explicitly called out. Have to reset the eprom as Techknight mentions? This is for the M8244G/B M8511 type.

Oh =( restart and get a sad mac 03001300/ 00001FFA, I see you had that too @ironborn65, also that it relates to the NMI line(?) any further advice gratefully received

Aha! Nice one @ironborn65 the Quadra drive was the only one I hadn’t tried, booted from the floppy no problem! It’s odd the older drives haven’t worked, one from the iisi works in that machine. But it’s a good start none the less cheers!

Morning @ironborn65 No still the same, just saying the floppy boots the Quadra

Hey thanks for that @ironborn65 I have tried a couple of other floppy drives, might be worth checking again tho. Disk is fine, booted (surprisingly) Q650. Yeah the Rascsi are similar, power over micros usb

Hi all, been doing some work to resurrect the portable but only getting as far as the flashing ? disk. Non backlit, standard power supply putting out 7.52v, I've recapped the board washed and dried (not oven baked tho) New lead acid battery and fresh 9v. The hard disk was trashed sticky and...

Thanks, I have at it with the scalpel and Dremel!

Thanks Moldy yes I’ve used them before, as you say can’t get hold of them now. I recon the 0809 probably has had them inside

@MOS8_030 if you have time could you show pics of the trimed down Cylon 0809 please, that looks very neat

Thanks @galgot good suggestion unfortunately just gave it a go and just get an error with "No battery could be found. Please try and reseat it"

@FABIO this is some progress at least! 🙌 I have a component tester perhaps I can identify dead components, when I get some time I’ll have a check over

same, put the pack together last weekend. Disconnected all the cables from the board joined the batteries together and then reattached the board, dead, not recognised by the mac.

Aha really, just ordered new cells :confused: you think the board gets bricked as part of reconstruction or after long term battery degradation?

Hi getting a 3400 up and running (240) lovely machine came with a 64MB ram expansion, recent few days it’s be raising an intermittent memory check error on start up and then only using 32MB. anyone have similar experience? wonder if it’s a broken solder connection or a mb connector issue? On...

Thanks I will, you too. So yeah the video is a tutorial on testing bridge rectifiers, my question was is it normal to get a reading on the two ac pins? I was getting .600ish in one configuration, see first two pics below. So as it happens the new rectifier turned up today and no, it’s not good...
