ULA is broken so I'm not be able to repair it.Ĭopiasoft made by JGComponetes because the old one was incorrect.

I update the website with all corrected data and files.ġ8/02/18 New fault: ZX with white screen. On the board, IC2 74LS125 pin 6 appears connected to the 'ROM2OE' signal (pin 15 on the tracks side).Ĭorrecting this error, the board designed by Merlinv works perfectly. In the schematic, IC2 74LS125 pin 6 appears connected to the 'HALT' signal (pin 15 component side). In the schematic there was an error that It wasn't on the PCB because they were created separately. With this scheme, his PCB didn't work and ask me for help. I update the schematic and the board of this interface.Ģ4/10/20 Merlinkv contacts me because he has designed a Multiface 3 PCB made by Hard Micro based on schematics found in this website. With his help, I have discovered a couple of errors that I proceed to correct. I update both articles including reference to this magazine advert.ġ0/04/21 José Gonçalves contacts me because he is checking his FDD3000 and He has found some inconsistency with the diagram on this web page. In this post of Retrowiki website (Spanish), one of the Ramjet+2 and Ramjet +3 designers tells some interesting things about these interfaces and put a link to an advertisement in MegaOcio magazine. I update the website with all corrected data and files. Was an error on the main board schematic and an error on the PAL DEC1 equations.Ĭorrected both errors, the Swift Disc 2 clone works correctly. The schematics and equations of the 3 PALs are reviewed.There Have cloned the Swift Disc 2 interface and it doesn't work correctly. 16/01/23 Now, thanks to Klaudiusz Fatla, we have an better scheme of FDD3000 with large PCB version.ġ6/01/23 Now, thanks to Albert Adell, we have the instructions for the Multiface 3 clone made by Hard Micro.ġ7/11/22 An user from forum contacts me because he
