It is designed with seamless compatibility in mind and thus doesn't use any of the crazy hacks other cards used to increase speed. I have 2 10,000 rpm U160 Seagate Cheetah drives on mine and they rarely get past 10 or 12MB/s. The same drives in a RAID 0 array on an ATTO Silicon Express NuBus card (in the same machine) tunred in close to 30MB/s and would top 20MB/s stand-alone. Thus I can only conclude the card isn't that fast. ATTO SEIV cards are still bootable (after a firmware upgrade) and are a devil to get working, but blow me they FLY, and yes they do use block transfers. I am not aware of any RAID solutions beyond level 0 and 1 for Macintosh NuBus systems. There was probably something, somewhere, which was rare and expensive, but it certainly wasn't common and probably wasn't a software solution. Anything above RAID 1 usually either is very slow in proportion to the system for a software solution or requires a hardware solution to get any decent performance, not to mention a bus that can shift more than 320Mbps. However, for data security on a NuBus system, I would probably pick up a few modern wide SCSI drives which will deliver 20 MB/s of real world performance (this is very different from the advertised interface transfer rates) and RAID them in a level 1 (mirrored) RAID. Each drive will max out the JackHammer during transfers and while writes would probably be at half speed (~10 MB/s because you're writing to two drives) most of the RAID level 1 software will interleave the reads so that you should get close to 20 MB/s on reads. You can never hope to muster 20MB/s standalone speed on a Jackhammer from what I have tried. If anyone knows something I don't however do tell, I'd love to know how to speed mine up! Another trick is to get something like a Quadra 900 or 950 and install two JackHammers and spread the drives across the JackHammers. However, Kaye Yum tried this and found that performance was not improved. He may have been using SoftRAID though. I'm not sure if anyone's tried it with an older version of RAID ToolKit. SoftRAID is relatively recent so it may not have optimized NuBus transfers the way it does on PCI systems. As I said, I got decent performance with the right card from RAID Toolkit. I feel it's a pretty good effort for what it does, and to be honest your unlikely to get much faster speeds on anything that is faster. -- Mark Benson AIM - SilValleyPirate MSN - [EMAIL PROTECTED] Visit FlatPackMacs online: http://fpm.68kmac.com Visit my Homepage: http://homepage.mac.com/markbenson Never send a human to do a machine's job. -The Matrix -- Vintage Macs is sponsored by http://lowendmac.com/ and...

I understand that you can't go much further than 98 with a 486 card, but that would probably still be a bit more modern than 7.6.1 (the offical IIfx max) or are these systems comparable (I don't have much knowledge about the windows os)?

Hardware problems with LC II
Hello, this is my first post. I'm from Italy and I own a Macintosh LC II with System 7.1: yes, it's very slow, but it works quite fine. Except for one thing, which is of crucial importance... the ADB port. It would be rather sad if I had to trash my old Mac just because that small port won't work. After starting up, if I move the mouse the pointer moves as well. But after one minute it freezes, and so does the keyboard. There's nothing left for me to do but shut it all down. Even starting up again won't help. Damn!!! This problem has surfaced only mere weeks ago. When I looked at the back of the LC II, I noticed that the ports (inside) and the holes in the plastic board (outside) did not coincide, and I thought this might be the cause. Thus I lifted the lid and looked inside, but I couldn't fix anything. The keyboard is all right (I have verified that myself), so it could be that the ADB port has worn out. Is there something I can do to bring my LC II back to life, or is it lost forever? Thanks a lot. -- Vintage Macs is sponsored by http://lowendmac.com/ and...

Re: Turbo 601 and the IIvi/vx Re: IIsi vs No Cofee
Thanks for the recent information, Jeff W and Gregg. I've just purchased a maxed out IIvx -- 68MB RAM, Turbo 601 card at 100MHz, uprated hard disk, uprated VRAM (don't know how much yet). The only disappointment is the mediocre Radius 8XJ video card but you can't have everything... So far I've had little chance to play but I'll check whether the Turbo 601 has been tweeked to fix the colour depth problem and whether the card will work in my IIci. Is there anything else to look out for? Oops, I've temporarily broken the IIvx by enabling the 68030 processor with Mac OS 8 on the system disk.

This is a card that only does 256 colors, but it will do a bundle of different resolutions up to 1152x870. Have you got the Radius Quick Color extension installed (get it from Gambas site)? If not then it might seem slow, but with it I think it works really well. The big thing (for me) is the drivers work fine with OS 6. I have two in my OS 6.0.8 Mac IIci. I have used them to drive twin 21 Mitsubishi Diamond Plus 200 VGA monitors (via adaptors) for fun at work for a while. Loads of space to six in :-) Back at home I normally use one to drive a Apple mono portrait. Then I get 256 grey shades - and it looks good. For mono monitors that's all you need.
