Hello Ezo, Thanks for your reply. in the lists of supported ICs, for the MCS-48,MCS-41 series of microcontrollers, MCS-48 adapter required. I do have that adapter. No experience here. OK. I cant find any explanation as to what is 'Vea', I suppose it is Vpp. I suppose it might be, but it would be nic...

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.

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.

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

I have a Willem EPROM Programmer 4.0. In the list of EPROMs, some have (PCB3) after the device number, for example: 2716 (PCB3) and 27C16 (PCB3), and some don't, e.g. 2764 and 27C64. What is the significance of the (PCB3)? Thanks.

I have a Dallas DS1225AD-150 non-volatile SRAM IC. Is it possible to program it with the Willem 4.0 programmer? I would have thought that at least reading it ought to be possible but when I try that, all I get is 04 in every location, even though I know there is some data in it. Thanks. Regards, Dave.
