The Mac Plus I use at home has an old, non-SCSI internal HyperDrive harddisk from General Computer. I presently use System 4.1, Finder 5.5 I'm considering buying more memory and use the newest 6.03 system. Is there a new version of the HyperInstall/Manager (I have V3R2) software that will allow me to do so?

First things first: forget about the 6.0.3 for a Plus. Not even a ``vanilla'' MacII is fully pleased with a 6.0.3 installed. This might be due to third-party inits that *are* compatible with the newest 68020 systems but, alas, not entirely with the 68030 Macintosh IIx and IIcx that the 6.0.3 is intended for. In a couple of days Apple's gonna introduce the 6.0.4 system that is required for the Mac Laptop... are you going to stick it in your Plus too, just to have ``the latest''? Human, thy name is vanity.... ;-) Secondly: don't even think of replacing your present 4.1 system/ non-SCSI HyperDrive combo (that is running) with anything newer than system 4.3. Even better still: leave it alone, don't upgrade at all. It runs now so why mess up a working non-standard-component system? -- ---- You just survived another load of gross exaggerations from ------- Ian Feldman, the ASCII hacker / "I work to live, not the ---------- ianf@nada.kth.se / ianf@sekth.bitnet / other way around" ------------- ianf%nada.kth.se@uunet.uu.net / uunet!nada.kth.se!ianf

This What are you talking about? 6.0.3 works just fine on a Plus. >Secondly: don't even think of replacing your present 4.1 system/ non-SCSI > HyperDrive combo (that is running) with anything newer than system 4.3. I must agree with you here. The internal HyperDrive is non-standard enough that there is little hope you can run anything newer than what General Computer Corp got working back when. Soon it might be time to junk the internal HyperDrive and move into the land of SCSI disks. -- Kent Borg "You know me, bright ideas kent@lloyd.uucp just pop into my head!" or -Mrs Lovett ...!husc6!lloyd!kent (from Stephen Sondheim's "Sweeny Todd")

I've been using system 6.02 since it came out on a HyperDrive 20. Use V3R2 to install.

The old HyperDrive stuff *almost* works with the newer systems. For example, if you boot from a floppy and then examine the drive queue, you will find that there is an entry in the drive queue for the HyperDrive stuff. However, the driver reference number is -1. This is why you can't mount any volumes: the driver reference number is bogus. I once wrote an INIT that found the HyperDrive entry and patched the driver reference number to be the correct value, and I could then use my HyperDrive with System 5.whatever. I think that the problem has something to do with the drive number. The HyperDrive likes to use 64 as the drive number. There is something in later Macintosh system software that does not like high drive numbers. I don't know what it is, but I too ran into it when I was working on a SCSI disk driver. My driver liked to pick drive numbers around 108, and it failed to work right. Changing it to prefer low drive numbers caused it to work. I think there was a tech note or an article somewhere or something like that once that mentioned what is wrong with large drive numbers, but I don't recall where it was. I would guess that HyperDrive would work fine with System 6 is someone could find the place where it assigns the drive number and patch this to use a lower number. Is this in the HyperDrive ROM, or is this in the driver that is installed into the System file? If the later is the case, then it should be doable. Tim Smith
