Does anyone know where I can get the schematic for the Willem 4.0 programmer? Thanks.

Dave.

Here are different versions of Willem 4.0 Mark your version from gallery

Hello Ezo,

Thanks for your reply. Unfortunately, I didn't find the schematic for the version 4.0 that I have. Is there anywhere else where I might find the schematic? Thanks.

Regards,

Dave.

Hello Ezo,

I've taken a look at the 'How to...' file and find that in the lists of supported ICs, for the MCS-48,MCS-41 series of microcontrollers, it gives this:

D8748,D8749,D8742,D8741, D8742 Vea = 18V

I cant find any explanation as to what is 'Vea', I'd appreciate it if you could let me know. Thanks.

The schematic is rather difficult to read, because there are many overlapping component values and reference numbers, etc.!

Regards,

Dave.

in the lists of supported ICs, for the MCS-48,MCS-41 series of microcontrollers,

MCS-48 adapter required. No experience here.

I cant find any explanation as to what is 'Vea',

I suppose it is Vpp. Not sure 18V required

The schematic is rather difficult to read

That is Willem original programmer doc's. Better than nothing.

...Willem 4.0 programmer

it's old hardware version. Apply 0.97ja or 0.97jc13 for parallel (ZIF/PLCC/adapters) memory.

I do have that adapter.

OK.

I suppose it might be, but it would be nice to know for certain.

Not sure 18V required

I wondered about that, too.

Indeed it is, but it does make things difficult.

I have 0.97ja but I don' recall seeing 0.97jc13.

I have been reading posts on the old Willem forum. Haven't seen anything relative so far.
