• 1 Mbit DIP DRAM. A full bank of eighteen 41000
• 256 Kbit SIP (Single In-line Package) modules.
• 1 Mbit SIP modules. A full bank of two modules
There are two forms of RAM noted above. The DIP DRAM
chips are single units that are installed individually. SIP modules are
mounted on a strip that plugs in as one unit. The two sections of each
SIP bank are physically in line, i.e., the two SIP modules for a bank
