(ToTsRETRO) DesTEST Mini - Is a bare minimal test to let you know if your computer is able to utilize the Max-Switch Test Cartridge. When Operational, the screen will flash white and black, with a corresponding sound. I've found that using the reset button can help with getting Sound, Although a SID Chip is not necessary to Utilize the Cartridge. It will also activate the Cassette Motor if you have one connected at identical intervals. Sparkle Dead Test and Diagnostics Run the same as the Original Dead-Test and Diagnostics, with three exceptions. One on the Deadtest you now will see a "Ram Screen" with Sparkle while the test is operational, no Black screen waiting to know if its working, you will know its working from the start. and Two the Sparkle will persists through out the test as a sign that the test is functioning and not frozen. This happens in the Dead Test as well as the Diagnostic Test. And Finally, when the Dead Test is Done, it will "SWITCH" to run the Diagnostics Test. From factorofmatt...... DesTest MAX-Switch The MAX-mode of the C64 expansion-port is truly a marvel since it allows the program on the cartridge to run right from the get-go bypassing the kernal and its assumptions about working memory. This convenience, however, comes at a cost: All but the bottom 4K of memory plus the kernal, BASIC and character ROMs are not available. That's why DesTestMAX only tests 4K! That's all it can test. The DesTest MAX-Switch (or just the 'Switch) solution aims to fix this limitation! The custom DesTest MAX-Switch cartridge adds the capability to switch (hence the name) between the MAX-mode and regular cartridge-mode under program control. The new DesTest Software allows the following features: Full 64K memory test using the March-B algorithm. No dependence on the ROMs, CIAs or SID: they can be removed. ROM checksum verification (if installed). CIA TOD consistency verification. The DesTest MAX-Switch hardware includes provisions for the following: Power LED. Most of the time when diagnosing or repairing a C64, the keyboard is removed along with the Power LED. The DesTest MAX-Switch cartridge includes a simple power LED to avoid mistakes like removing or inserting ICs with the power on. Reset Switch and LED. A faulty reset-circuit in a C64 can prevent it starting-up properly. A reset-switch can temporarily bypass a faulty reset-circuit and the LED gives a visual indication if something is wrong!
