Has anyone developed a homebrew ST506 interface for an A1000? I'm not yet ready to go to SCSI, but I have an ST506 type disk that I would like to hook up. I saw a commercial product some time ago that looked like just a PAL and a few capacitors and resistors, but I don't remember the manufacturer. It should be a simple process to hook one up, although the performance won't be great... .no sig yet Greg Stovall, Bell-Northern Research, Inc. Richardson, Texas (214) 907-7009

Among them is a project through which you can interface an IBM hard drive (with IBM XT style controller) to your Amiga. It uses the A500 expansion port, which (please correct) also exists on the A1000. Alan whinery@hale.ifa.hawaii.edu

It was about $100, and gets complete schematics, drawings, parts list, suppliers, and (most importantly) software. In theory, everything but the software should be easy for a good hardware hacker to come up with from scratch. What MAX does is allow you to attach an Western Digital or OMTI controller (PCXT 8 bit or PCAT 16 bit) to your Amiga's bus; you can then run ST-506 MFM or RLL drives (up to 2 controllers, each with up to two driver) with their driver software. The software is a set of interrupt driven disk device drivers, and Palomax claims up to 300Kb/Sec transfer rate with fast drives and a 16 bit RLL controller. They also include some installation and testing utilities, and a backup program. The package is probably worth what they are charging ($99 last I heard), especially for the software. I haven't built it yet. Wildstar
