Alan provides three programs for the MonSTerBoard: M_FLASH.ZIP to write the onboard flash, M_ALTRAM.ZIP to configure the RAM (2, 4, 6 or 8 MB, then placed in the auto-start folder), and M_RTC.ZIP for the Dallas RTC module. In total you can install four TOS versions: two 192 KB and two 256 KB images.
In my Mega ST 4 "High" machine the MonSTerBoard provides the 8 MB of TT-RAM that TOS 2.06 and Geneva use for real multitasking, plus IDE storage for the mass storage. Combined with the ET4000 graphics card and its dedicated monitor, it's the most capable machine in the fleet.
+In my Mega ST 4 "High" machine the MonSTerBoard provides the 8 MB of TT-RAM that TOS 2.06 and Geneva use for real multitasking. For storage I use the dual IDE interface, with a CompactFlash card attached and booting the system directly from it. There's no ACSI hard drive connected in this machine; the IDE boot is noticeably faster than an ACSI drive would be. Combined with the ET4000 graphics card and its dedicated monitor, it's the most capable machine in the fleet.
