Thanks for the link, Steve.

I previously found a MS 135 HT-2 data sheet on Isel website, but their current was lower.

So I'll probably go with your drivers or an equivalent, as you seem happy with them.

Ok, as I'm too lazy to have a look at my machine which is not very accessible for the moment, I'll ask another question.

Do you still have the original Isel IMC4 controller at your fingertips? Could you please check if the driver chips (IIRC correctly, they are located at the top of the card, screwed to the case) are L292?

If this is the case, it means that a 2.5A current is sufficient and I'll probably buy smaller and cheaper drivers.

Thanks in advance.

I eventually managed to open the back cover. Drivers are L292, limited to 2.5A.

I found the electrical diagram of the IMC4 controller here:

For those who want to upgrade the machine without changing the whole electronic part, this upgrade card may be interesting (requires Kay control software):

Hi Steve I recently picked up a Unimatic Educam 20 from a college with licensed dongle and using Galaad 3 but cant get the laptop to allocate a comport. Have you heard of this problem? T.I.A Regards Brian
