SIMM sockets on their motherboard one for Chip RAM, the other four for Fast RAM. The sockets accept industry standard 3. SIMMs. The four parity bits of the 3. EDO RAM is not supported by the motherboard RAM controller, Ramsey, but some processor cards accept it and some even use its benefits. The Chip RAM socket has to be filled with either a 1 or 2 MB SIMM. Barbie As Rapunzel A Creative Adventure Game. The four Fast RAM sockets accept 1, 4 or 8 MB modules up to a total of 1. MB Fast RAM. The SIMMs cannot be mixed and the 8 MB ones have to be placed in every second socket. Late models have the four Fast RAM sockets only. The fifth socket is missing, it is replaced by 2 MB 7.

The Zorro, ISA and video slots are all placed on a daughterboard which is mounted vertically on the motherboard. All the ISA and video slots are in line with a Zorro III slot. The video slot is extended with 1. Amiga models in order to support the AGA chip sets 2. The three ISA slots have their power and ground pins activated only. In order to access the slots by the A4.

Inactive slots can be used for non intelligent cards like TBCs or fan cards. The processor card slot is physically the same 2. A3. 00. 0T. However the processor cards designed specially for the A3.
