Yo compacters everywhere, To our Jeff Walther's at [EMAIL PROTECTED] question:
<< I found a couple of the old Apple external hard drives which connect through the floppy port. I can't remember the exact name for them. I'm thinking about buying them, but I don't know if they work. I figure the electronics are probably still good. Can the hard drive mechanism inside be replaced with something more modern or are the electronics built to only work with whatever is currently in there? What type of hard drive is in there? Is it a SCSI or IDE or (gasp) RLM?>> Our "J.S. Garrison" <[EMAIL PROTECTED]> responded: <I own two of them and they both have a SCSI 20MB Rodime hard disk. Chances are another drive might work, unless the converter, (from floppy to SCSI) is controller sensitive.> I do believe we may be speaking of two different but similarly named external drives here. The HD-20 is the 19 pin drive plugging into the floppy port. The SC-20 is a SCSI drive plugging into the 25 pin SCSI port. Inside the drive boxes, these are not the same nor even related drive mechanisms at all. I've a small number of working HD-20 drives. However, looking to resurrect a dead one by replacing its drive with a SCSI drive, I found the SCSI drive would not fit in the box, work with the existing cabling, nor would a power supply and cabling from other sources work with this box. Memory tells me that the HD-20 was an MFS (Macintosh Filing System) only drive that Apple HDSC Setup and other HFS formatters do not recognize. It seems the HD-20 was a transitional device to get Apple into the "real" computer business in the 512k/512Ke era. The Plus introduced SCSI and the rest is history.
