:The 4.77MHz CPU frequency is an error made by the English Wikipedia. Then other websites parrotted and the error is everywhere. Now Wikipedia uses the sites that used its wrong value as a reference, which cements an incorrect value. The correct one is 6.14MHz, effective 3.07MHz. You can read more about it [https://bitspassats.com/index.php/IBM_System/23_Datamaster here].

:I forgot. About the ROM memory, the answer is tricky. The service manual states 112KB, and this is not an incorrect value, but that's also not correct. The system contains fourteen memories of 8KB each (112KB) in early versions of the machine, but it was patched early in production and most units have sixteen memories (128KB). So the correct answer is 112KB/128KB. --[[Utente:Buran Biggest Fan|Buran Biggest Fan]] ([[Discussioni utente:Buran Biggest Fan|msg]]) 09:50, 16 apr 2025 (CEST)
