    The A24EM can be part of two development systems. This chapter describes those systems and explains the layout of the A24EM. DEVELOPMENT SYSTEMS Your A24EM can be part of two Motorola development tools: the HC05 Motorola Modular Development System (MMDS05) or the M68HC05EVS Evaluation System (HC05EVS).
