They are fairly easy to get, but the list price on the ones with which I am familiar is in the neighborhood of $70. It kind of guts the economy of putting affordable IDE devices on your SCSI chain. Acard makes a variety of adapters, with the variation being different flavors of SCSI. The narrow ultra-SCSI adapter is the AEC-7220U. If you visit Acard's website you will find that their price on it is $69, but I think they ship from Taiwan or some such. It is better to find the US distributers and buy from them (if you're in the USA). IIRC the USA distributers are getlaptop.com and microlandusa.com. Newegg sells some Acard products, but I don't know if they carry the SCSI to IDE adapters. The Acard models have (?) extended LBA support or whatever it is called when disks larger than 137 GB are supported. It might be kind of funny to put a 500 GB IDE drive ($90 w/ free shipping at Frys.com; Seagate 5yr warranty) on some machine from the late 80's with an unenhanced SCSI port. How long would it take to write the whole disk at 3 MB/s? Jeff Walther
