I just tried my old Dragon 32 and... tragedy! A strange weird green screen. It changes and can have more or less chars. I have tried to look for similar issues but I have found only plain green screen. Any ideas?

I have found an SF354 with a weird PSU connector and I cannot find any info to make an adapter... :-( The connector is a female DIN7... do somebody has info about it? Thank you

I have some drives but I haven't seen any jumper! :-( Perhaps they are under the external metal skin... I have tried what you proposed, I have disconnected the 5.25 drive and connected a modern 3.5 one but it does not work. I am afraid this is a limit of the SPEM HW... I have tried the same with...

DS1 or DS2 in modern floppy drive? The type is chosen with the cable... or not? 🧐

Hello, I have bought a Robotron KC87 assuming it was working and it is, in a weird way. When I turn it on, it shows a page full of coloured squares. After some seconds this page lifts (as expected) and I get a red page with a cursor. If I type BASIC it switches to the blue page. It is a...

Dear Group, I have been given a system like the subject. Everything has been ok for some minutes... I have been able to read a dir of a floppy and then to launch a program from that floppy. Then I wanted to make a case with two black floppies, one 5.25 and one 3.5 (both included in the kit, but...

Thank you for your help. I erased the EPROM and burnt the v3.1 and now the computer starts! I have to reconnect everything and today I cannot but I am happy! :)

I resocketed all chips (RAM chips apart, assuming that a bad RAM chip would not prevent the computer to start) and the computer behaves in the same way: it boots and after some seconds it start a continuous intermittend beeping. I have seen that one BIOS is different than the other and "I hope"...

My A3000 is the UK one so that it has "only" link 24 and 25. I have simply tried all 4 possible combinations and I had no results (I have not tried without any jumper in link 25, since it is not supposed to do). Please note that in my first picture of the video I have canceled a sentence in my...

My first idea was simply to have a position with all Apple HW... even if it's possible (100 model apart) I think it's tough and I do not have big competencies in this field. I have a Philips color monitor with composite input... I think I will give it a try... :-o

I did not know the 100 before today. I think it is too rare to hope to have one (rate and obviously expensive). I knew about the RGB issue but this could be easy... I have found tools with composite input and RGB (or other types) output. The Hfreq is the issue... 😔

I feared this. Does exist a (cheap) tool that can modify the H-frequency? I tried to search but I am not been lucky.

Hello, I would like to connect my Apple IIe to a colour monitor and I would like to use an Apple one. I have a M0401Z and it could be a good solution but I am not an expert in Apple HW and I know that Apple monitors are not so flexible. Do I have a chance?

In the meantime I have found 24 and 25...

I have also found the attached PDF. So I have to work on five links (I suppose the first two are the most important). Now I look for their position. I am not at home in these days but I will try next weekend. Thank you
