CyberStorm PPC

> Company: Pahse 5 Digital Products, Germany
Date: 1997
Amiga: 3000, 4000
Interface: CPU slot
Autoconfig ID: 8512/100

PowerPC 604e @ 150 / 180 / 200 / 233 MHz
68040 @ 25 MHz or 68060 @ 50 MHz
It can be ordered without a 680×0 companion CPU to put an existing one into the socket

our 72 pin SIMM sockets accept 128 MB RAM
supports 4, 8, 16, 32 MB SIMMs 60-70 ns
64 bit interleaved RAM access
the Cyberstorm PPC is a bit picky about DRAM Chip Memory Array organization
the card only has 11 address lines, thus only 2048×2048 organized DRAM Memory Arrays are supported
1024×4096 organized chips would need 12 address lines and are not working
the Memory Array organization is given in the chip datasheet and not to be confused with the output bit configuration (e.g. 4M×4) of a DRAM chip
if the chip has the wrong organization, only half of the RAM is recognised

NCR 53C770 Ultra Wide SCSI controller – follows the Wide Fast 20 standard, supported by NetBSD
expansion slot for the CyberVision PPC
the SCSI controller needs the INT2 signal which is not present in the A3000’s CPU slot
