I posted this in a thread in the 8bit area but it applies here. My brother works at a computer recycling facility here in town and I get called whenever they find Atari stuff. This is the latest find.
Latest Atari Find
Just powered up the 1040STf with my MegaFile30 and ran the system info utility. This little bad boy has 4mb ram in it!! Cracked it open and found a Marpet MP210A ram board in it with a full 4meg of ram. Also had TOS 1.4 (Rainbow).
The 520ST also had an upgrade in it. It has a Aerco easieST solderless ram board in it. It has 1mb. Would like to find documents for this to fill the other bank.
