Well, even if this #Atari 520ST factory mod bumping #RAM to 1MB looks like a small tram rails - it sadly needs to go. Replacing too many of those piggybacked chips - and more and more are failing - all need to go and be replaced by two 2MB - 1Mb x16 chips with 60ns label!

This... Those RAM chips are faulty, probably the top one. Let's fix this Atari 520+ with factory upgrade #atarist

witch itself is a modern replica by Przemyslaw Wegrzyn - to load a game from 1985 It's just as complicated as this sentencje! #hobby #elwrojunior800 #retrogaming

And it works! Polish replica by Przemysław Węgrzyn with help from Mikołaj Cichal and the whole #Elwro 800 Junior group - works fine when used with Polish UCY74LS04. CEMI, you better ramp-up the production lines. Thanks to all involved, it was great fun! #reteoreplica #z80 #zxspectrum

Did you know? Back in the 80ties Poland's #Elwro created quite good #ZX #Spectrum compatible Junior 800. With education in mind, they added networking! Now - thanks to Przemysław's hard work - you can build a Full replika with this open source project: https://github.com/codepainters/e800j
