|Memory Upgrades – Early Models The EIV and e-64 use the early mainboard which takes eight 30 pin SIMM sockets. You can fit pairs of 1/2/4/16 MB up to a maximum of 128 MB. But do not try 8 MB SIMM’s, the Emulator will not recognise them. Memory Upgrades – Later Models The e-6400, E4K and E4X have two 72 pin SIMM sockets which will take any combination of 4, 16 or 64 MB RAM (NOT 8 or 32MB SIMM’s). There are another 2 SIMM slots next to the RAM slots, these take Sound ROM SIMM’s (see below), but only one (ROM slot 1) can be used.Sound ROM The EIV family can be fitted with one E-Synth or Orbit/Phatt Session 16 MB ROM.
OS Upgrades Although EOS 4.10 is the latest version. EOS 3.0 is no longer available from the E-mu Systems.
Digital I/O (e-6400) This card provides AES/EBU and SPDIF digital ins and outs and an ASCII connector for attaching a keyboard. Emu P/N 6815 – $249.
Hard Disk Mounting Kit This very simple kit enables at internal hard drive to be fitted to the models that do not come with a drive. Emu P/N 6301 (E-64 and e-6400) – $30. Emu P/N 6911 (E4K and E-Synth) – $39.
Utracize The EIV later models cold be upgraded to full Ultra specifications (see the Ultra Specifications), by swapping out the mainboard and back panel at a service centre. The upgrade costs from $995 – 1395. The earlier models can not be cost effectively upgraded – as everything has to be swapped out.
