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...

Hello, I have been looking for an Archimedes at a decent price for years and then I found it. The issue is that I cannot get a clear image (and probably other issues) as it can be seen in the attached picture, using the mono connector that I suppose is a composite one, right? I have also...

Dear Group, I have a NoName clone with a strange behavior. If the PSU is not connected to the mobo and I turn it on, it starts and, for example, the HDD and the FDD turn on. If the PSU is connected to the mobo and I turn it on, nothing happens... the PSU remains turned off. Something in the...

Dear Group, I was using my Apple IIe when something exploded in the external FDD Duo. After this, the Apple IIe has two behaviours: when the FDD card is inserted, "Apple II" appears on the screen without any other possibility (since the FDD is dead), and I think this is normal. If I remove...

Dear Group, I have a Robotron KC87 not booting. When I turn it on, the two leds immediately turn on and I have read that this is not good. 😔 My KC85/1 does not behave in this way. I have an RGB cable and (obviously) I get no image. I have read that it could be a dead CPU and/or ROM: is this...

Hello, I have been gifted of a NanTan FMA2100 laptop computer without the two batteries but in quite decent shape. The PSU connector should be a 2.5/5.5 mm. Can somebody advise me about the voltage and if the positive is on the tip or not? The computer can work WITHOUT the batteries? I attach...

Hello, just to be sure. The error in the photo from a Mac SE FDHD means a RAM module is "sick", right? Thank you very much for the quick help
