Hello, I built up an adaptor to use with the NVRAM lib and – it works great! :D In the picture testing of a fast static RAM (cache RAM) can be seen. SRAMadptr.jpg Pin 34 of the emulation header can be used to supply the RAMs. I noticed that Dataman counts the pins different to the connector producer...

Hello Neil, thank you for your hint. The Dataman-40Pro is a nice device for sure, but as stated above I want to use the S4 if possible somehow. It is only for private use, no business case. I figured out that pin 34 of the S4's emulator socket carries 5V when S4 is on. Is this pin able to supply up ...

Hello All, I want to use my beloved S4 to test static RAMs. Does someone made experience with it? Best would be to find a library for that. Well, if not, first idea is to use the 8-Bit NVRAM library. In general NVRAMs have same pin assignment and should have the same read and write cycles as normal ...

Hello,

I'm looking for a MCS51 adapter module for my S4. Because a new one is not really cheap can anyone offer me a used one? Or does someone know where I can get a used one?

Thanks in advance!
