You can use Memory cards to store as many as 2350 PCM 80 registers (47
banks of 50 — on a 1 Meg card). Registers stored on a properly formatted card
will be recognized whenever the card is inserted, and can be accessed via the
front panel Register Banks button, exactly as internal registers.
Memory cards can also be used to store "setups" (your system configuration,
as set in Control mode). As many as 5 PCM 80 setups can be stored on a card,
allowing you to transport not only your effects, but complete PCM 80 environ-
ments to another PCM 80. Cards also provide storage for additional program
maps and effect chains.
See Control Mode Store and Load functions for details on saving setups on a
card and reloading them.
Memory cards must be of the following type:
PCMCIA SRAM Memory Card — 68 pin, Type I
Usable densities: 64 kByte
128 kByte
256 kByte
1 MByte
Access Time: 250 nsec or faster
Conforms to PCMCIA 2.0/JEDIA 4.1. Can use either 8-bit or 8/16-bit bus configuration.
Attribute memory can be present, but is not used.
Memory cards can be used to store
PCM 80 registers, or setups.
Memory Cards
The addition of SIMMs (memory modules) allows several PCM 80 algorithms
(Glide>Hall, M-Band+Rvb and the Resonant Chords algorithms) to address up
to 4 Meg of delay memory, providing as much as 42 seconds of stereo delay.
PCM 80 memory can be expanded with SIMM memory modules of the following
type:
30-pin SIMM Memory Module
Usable densities: 1 Meg x 9
4 Meg x 9
16 Meg x 9 (See Physical Requirements. Note also
that only 4 Meg will be addressed by the PCM 80.)
8-bit SIMMs are not usable
Access Time: 70 nsec or faster
Physical Requirements: Either 3-chip or 9-chip modules may be used,
with the following size restrictions:
Maximum size: .208" (5.28mm) total module thickness
1.30" (33mm) total module height
3.50" (88.9mm) total module length
Expanded memory is automatically detected by the PCM 80. The presence of
additional memory will initiate internal power up testing which is longer than the
unexpanded PCM 80 time period.
Safety issues and various agency approvals mandate that memory expansion
be performed only by qualified service personnel. Instructions for performing
this procedure are, therefore, available only in Lexicon's PCM 80 Service
documentation.
