some posted around 900kbs, but if the OS was PPC the PCMCIA speed will also go up? correct me if im wrong..

 The max throughput of the PCMCIA port is limited by the A1200 motherboard, using PPC software could help remove some of the bottlenecks in reaching that speed though.

@doobrey

so there is some sort of speed-up..

if this is the case then any PPC OS on classic amigas with PHASE 5 board will also let-off more heat..( ie no 68k, PPC chip works at full speed [[[  more power more heat ]]] correct me if im wrong...

I wouldn`t say "is", more "maybe", it all depends what you`re offloading to the PPC.
 As for using a "PPC only" OS, I`ve got no idea, I`ve never had a PPC`d Amiga to play with, dunno if the dreaded context switching would hurt PCMCIA access or not, or is it short enough to not worry about?

Hi. I've looked for a SCSI network card once but couldn't find one. Does anyone know if a SCSI network cards exist? That would use DMA with low CPU overhead and have higher throughputs..

A long time ago, in Amiga past a company called C Ltd released a series of scsi controllers and a driver that allowed networking over the A500/2000/A1000 C Ltd.

I am not sure what the status of these things are currently (if the drivers would even work with the current version of AmigaDOS). However back in the early 90s (before the A3000) we actually had one of these systems working in the computer store I worked in.

SCSI NETWORK? i did not think it was possible..


well i tell you what iv got connected to my scsi chain maybe it possible with my unit..

its a PCMCIA type I-III controler connect to my SCSI chain..it has it own local MOTOROLA processor & CONTROLER on board..

according to the manual if i insert any type of flash card if it does not like it, it will try & do its own formatting...


you can also upgrade the rom chip..( i think flashable as well )..


i can insert any 16bit cards & the unit can see it...



this unit is very expensive just over £300.00
