Matt also released Des-Test Switch, which is a cart version that can fully test all 64k of RAM. This is a combination of Des-Test MAX and the Des-Test Kernal which switches modes on the fly. (Normally MAX mode carts like "Deadtest" can only see the first 4K of RAM.)

@factorofmatt.bsky.social @janbeta.net @adriansdigitalbasement.com Would it make sense to make a "pictorial fault guide" with DeadTest/Diagnostics/DesTestMax inserted, i.e. where you link observed behavior to specific parts? (1/n)
