I would try Uniflash; if nothing else it should report the chip's information. You can also find out more by peeling the sticker back and Googling the part number you'll find underneath. I do know that the PCChips M507 comes with an EPROM rather than an EEPROM so, on that motherboard, you cannot …

Someone asked me for the setup disk (aka user disk) to configure the Olivetti PCS-44/C. I put it here for the benefit of those who need it, along with an extract from the service manual. One disc is specific for the M4-40, PCS-44/C and Familia 2 models and is in Italian, and that's what I used. The …

I will have to solder another CR2450 battery, this …

This is the correct pinout so at the end: (always see from the solder point and counter clockwise) - pin 2 minidin7 to pin 5 ps2 connector (red cable +5v.) - pin 4 mindin7 to pin 3 ps2 connector - pin 5 minidin7 to pin 2 ps2 connector (black wire GND) - pin 6 minidin7 to pin 1 ps2 connector. So, if …

Hey guys, finally we made it! Thanks to Michael I passed a night to test on the mainboard and we found out that a pin in the ps2 connector was too out of the connector, cause soldering the plastic melt a bit and moved that pin that made no contact with the keyboard connector. Today I adjusted this …

What's that DE-9 keyboard connectors? Is that a standard? DE-9 is the connector shape used by the small serial ports. See for example here: https://it.wikipedia.org/wiki/D-subminiature. The connector shape is standard. There is no standard for PC keyboards using a DE-9 plug, though. How can you …

Verify, lookup, check & recheck & verify again that the pinout you are using is correct. The sides are switched. you're putting 5v from the computer on the ground of the keyboard and putting the ground of the computer on the 5v line of the keyboard. (I am that "Michael" who helped in the process) …

Red and black can be soldered permanently, you can use the 'on the way' method for the rest of the signals, clock and data. You didn't followed the instructions, i can see from the start that the red and black wire are not connected ok on the male minidin7 (plug that goes in to the computer). Use …

At the moment I gave up cause I was going completely mad about that, this happens cause I am not sure what to do and expecially cause I am not understanding very well what to do. I think I made a mess with numbers of pin, I have to clear my mind about that. Assuming that we know in each connectors …

I decided to try those connector "on the way" to not every time solder and desolder. Anyway I am not succeeding, always the same error 8, keyboard error. I can measure 5volts, but I see no lights on the keyboard. It is normal?

Anyway I take some minutes to study and understand the logic behind your post of soldering instructions and I have fully understood now. We know where the +5v are on both connectors, we know where GND are too. The thing is to search correctly where DATA are and where CLOCK are in the 7pin minidin …

I used a numbering of the pins that's easier to understand/work with, but if you want to count right and left i have nothing against it :). Let's analyse it, pin 4 in your picture means pin 5 which is 5v in both cases (because you gave me in this picture the pin out of the female ps2 connector from …

Good, let me know if you need any clarifications. So, these are the connectors opened completely. I put two images. I think that the image you gave me before with the pinout was wrong, I cannot find on these adaptors, they are different. Please tell me what to do , and please give me the pinout …

Here is the pin out assuming you are looking at BOTH CONNECTORS for the adapter from the soldering part of the pins. Pin 7 will exist only on the male minidin7 connector and it's unused as also some other pins. - wire from pin 2 of the male minidin7 to pin 5 of the female minidin6, +5v dc, use red …
