I've been reading some articles here recently about how the Commodore 2090A disk controller has "brain damage." What does the new 2091 have that makes it superior, other than being a 2090++? Would somebody out there who has an informed opinion please tell me what kind of brain damage? I have had my 2090A for about 6 months now and I have not noticed any such thing. I'm using it to run a Quantum 80S drive and have been getting very reliable, and reasonably fast ( ~100Kb/s with FFS **) performance from it. I don't consider this to be brain damaged in the least. What gives? And why do some of you not like it? I've had no problems. ** Results using a disk performace utility of my own design. This is average performance measured writing a 128K byte file in 4K byte chunks on a moderately fragmented disk. In other words, real world performance. Of course, If I write in 8K chunks on a completely fresh filesystem I get more like 240K bytes/sec. The larger the chunk size, the better the performance. But really, now, who has uucp software that reads and writes 64K bytes at a time? :-) -- Kevin L.
