Description: This is a Phase 5 Cyberstorm Mk II board, seen here with a 60mHz clock on it and a slim fan on the 060. (It just fits under the drive chassis of the A4000T.) Was very expensive in its day, around £650 !!!! And that's without the 128mb RAM you see there. Also purchased, but not attached, was a CyberSCSI module. It cannot run on an overclocked MkII board, and is much slower than the stock 4091 board anyway (as tested with several drives). I also tried a 66mHz crystal but I had intermittent crashing and soon yanked it out.

| Ilwrath Posts:2199 | August 05, 2004, 02:39:13 AM Oh yeah! That's right... There was an anti-tamper seal over the crystal! (Originally there was a white strip that connected those two glue points.) Mine had one of those when it was new, too. :-) I just cleaned it off so many years ago, I forgot all about it. haha! |

I just took the Miggy apart again, trying to find loose connections, and I had a closer look at the Cyberstorm: those red and silver things are not conductive at all. They are simply anti-tamper strips. Don't worry, I've ordered myself a set of bifocals :-P |

| August 04, 2004, 09:54:29 AM @ x53: I found a flasher for the SCSI and I will sort that out once my mouse problem is fixed (you need to boot with no startup-sequence to use it) Edit: I found mine here: http://amiga.resource.cx/exp/search.pl?product=cyberstorm @ tjLazer: does your CS have those silver and red connections near the 060? |
| TjLaZer Posts:3244 | August 04, 2004, 01:54:16 AM I also have a Cyberstorm MKII 060 and run it at 60MHz. I also get crashes at 66Mhz. This is due to the RAM not being "up to par" so to speak. Better ram would work but it's too much of a hassle trying to find some. I use to have a MKII before and I had some generic RAM and it worked great at 66MHz! I also have a GVP-m 4060 at 66MHz but due to the summer heat it's back down to 50MHz. Works great otherwise at 66MHz. |

You should update it to the latest version and then see what the benchmarks say, that is if you feel like playing with all of this. :-) Go to http://www.dcecom.de/downloads.html and get it. I'm not sure where it's located, but possibly in the archive called "scsi_tools.lha". |

| August 03, 2004, 10:09:21 PM @ lwrath and X53: I have the Super Buster Rev 11 in an A4000T. Here's how I know that the CyberSCSI is slower than my stock SCSI card: 1) I tested three different hard-drives on both controllers. I can't remember what the programs were that I used to test them, but I do remember that I noticed a subjective speed decrease when I changed to CyberSCSI and that SYSinfo was reading as much as 1mb/s difference between the two, thats when I decided to test them. The CyberSCSI lost all the way. As a matter of interest, the only device that worked better on the CyberSCSI was my external Zip Drive. 2) I made several 500mb animations with VistaPro and had them played back directly from disk, first using CyberSCSI and secondly the 4091. The CyberSCSI caused jerky playback. 3) I phoned up the distributor (? White Knight)and asked them what the deal was, considering I had tried all the different settings and the CyberSCSI was slower, and they contacted Phase 5 and then got back to me and told me '...we make no claim as to whether the CyberSCSI is faster than your A4000T scsi interface, we provide it as a SCSI solution for the Cyberstorm MkII...' In other words its aimed mainly at 4000D owners who have no SCSI anyway. The backplane connector was designed for an A4000D and I had to make my own to use external peripherals such as my CD-writer and Zip Drive. 4) But the most convincing reason you should believe me is because at the moment the CyberSCSI is in a box, gathering dust. I already paid for it, couldn't get a refund, so I have nothing to gain by claiming the 4091 is faster. The only thing I can think of is that I have an early version of the CyberSCSI? Were revisions done? I have one of the first ones produced, I was actually on a waiting list for it. @ lwrath: I don't know what those red and silver connections are...I thought all MkIIs had that. I haven't seen another MkII and that is how the board arrived. Nobody has touched it. |
| x56h34 Posts:2921 | August 03, 2004, 07:51:23 PM Hmmm, I find it unlikely that CyberSCSI is slower than anything other than perhaps CSMK3/PPC SCSI controller. CyberSCSI should be better, or at least about on par with the following: WarpEngine SCSI, BPPC SCSI, SCSI-IV kit. |

That's a benchmark I'd like to see. Seriously. Was that from an A3000 or A4000? What revision Buster? I've never owned the 4091, but I did own a FastLane Z3 on my A4000 (SuperBuster 11), and my CyberSCSI ate it up and never looked back. Anyhow, it's a great shot of the Cyberstorm MK2. (one of the very best Amiga cards, ever) Does yours have some kind of patch/fix applied to it? What are the red and silver things over by the 68060 CPU? |
