Hi all,
I've been tearing down my SE/30 and thought I'd put up pics of the accelerator, a 33Mhz '030 Sonnet Doubler/Allegro designed for the SE/30 and IIx.
This would have been the poor man's SE/30 upgrade, very simple in design and has timing issues being unable to boot from a HD floppy at startup, and reportedly either reduces the CPU speed or floppy read speed on the desktop to read from a drive (once the driver has been installed). Some earlier B&W game sounds are too fast, but most are OK. However, it's reliable, never gets warm and is snappy in use. I'm running a IIfx ROM in mine and must try later OS releases to see if later versions of Sound Manager make any difference.
Years ago, I posted about some issues with the card
Enjoy,
JB

SE/30 + Sonnet Allegro Doubler = wonky system sounds
Hi, I treated my SE/30 to a Sonnet Allegro "doubler" accelerator, boosting it to 33Mhz '030 off the socketed board. It installed easily bar having to lengthen the legs on a replacement capacitor nearby to make it fit. It has 80MB RAM, 1GB HD, with a PDS network card, so fairly stock apart...
