The board fully passed every test, proving to be perfectly stable and reliable. Edoardo only encountered one minor issue plus another one I was already aware of, as it had been reported by @LIV2, both of which were easily corrected. He also came up with a number of suggestions for improvements which I incorporated in a new revision of the board which is now under testing.

TBH, if it were for me, I wouldn't have released any sources any more but I felt that Edoardo did such a huge job that he deserved to be the one to choose what to do (besides getting his moniker among the credits on the silkscreen). He chose to keep it open source and so be it. This means the "community" will soon get fully tested schematics and gerbers for an Amiga 500+. A lot of great things could be born from these, let's see what happens. Someone else I would like to thank is an Englishman named Ibrahim Imran: he ordered some boards and even sent one to me for free. He intended to try and assemble one but was halted by personal circumstances. I am a bit worried because I tried to get back in touch with him several times but he never replied. I hope he's doing well. The board he sent me was first of all a pleasant gift (you know... after 2 years of work on that project, you finally get a physical board in your hands, aaaaaah!) but it also proved very useful for testing the dimensions, connector placement and choosing positions for the new features. One more time, this is a small example of how the open development model works and how it thrives when everybody does a little bit. I really wish the "community" really took this to heart and started supporting open projects rather than the selfish and greedy speculators they are standing up for right now.

12 Aprile 2020 Postato da: SukkoPera Raemixx500: Nuova mainboard A500+

Avete un uovo di Pasqua vuoto? No problem, lo riempio io virtualmente io con questa nuova scheda che pubblico oggi! Si chiama Raemixx500 ed è un remake della mainboard dell'Amiga 500+. So che ce ne sono già altri in giro, ma al solito nessuno è totalmente Open, al contrario del mio. Per ora è molto fedele all'originale, vedere il sito per le differenze. Il problema è che non l'ho testata, perché non è economicissima da produrre. Se qualcuno volesse lanciarsi con me in questa cosa, senza alcuna garanzia, credo che con altri 2-3 partecipanti si possa mantenere il costo di una singola scheda sotto i 25€. In ogni caso, fatene buon uso, ci ho lavorato più di un anno (non continuativamente, il che in realtà complica le cose...). Anche senza certezze di funzionamento, avere schema e PCB su KiCad può essere utile per il troubleshooting. https://github.com/SukkoPera/Raemixx500 Buona Pasqua .
