I'm not familiar with the model numbers, but your later description (8 jumper positions) agrees that this is the original Apple SCSI card. The firmware revision can be identified by looking at the part number on the EPROM label: 341-0112A is revision A 341-0112B is revision B 341-0437-A is revision C You need revision C to use the card with GS/OS in a IIgs. > So I try to connect an external HD that works on my SE/30.

The IIgs needs to boot from the first partition, so it would be a better idea to swap them over, with a 32 MB partition first, and the rest as HFS for the Mac (which can also be accessed by the IIgs as a data volume, via GS/OS only). If the drive is large enough, you will probably be better off creating at least two 32 MB partitions, as that will give you plenty of space to work with in 8-bit software. (The exact maximum size of a ProDOS partition is 32767.5 KB, which is 512 bytes shy of 32 MB.) > But i cannot find on the IIGS any tools to initialize the disk. What tools > do i need ? Advanced Disk Util don't see the disk. Some obvious things to check: 1. The slot containing the SCSI card must be set to "Your Card" in the control panel. 2. You need the SCSI drivers installed on your startup disk. At a minimum, you need SCSI.Manager and SCSIHD.Driver, but the safest method is to use the Installer to set up the system disk as required. The System 6.0.1 "Install" disk has the SCSI drivers, so booting from it should allow you to see the hard drive, and it provides a method of erasing volumes from within the Installer (just make sure you erase the right one!) You probably won't need Advanced Disk Utility, as its primary use is for partitioning a hard drive, and you've already done that on the Mac. (Partitioning again on the IIgs will destroy the contents of the HFS partition on the drive, and may render the drive unbootable on the Mac.) 3. The drive must be terminated (using either internal termination or a piggy-back terminator connected to the back of the drive). If you are connecting two or more devices to the original Apple SCSI card, you need to terminate the first and last devices. 4. Something has to provide power for the SCSI termination. This is not a standard feature of older Apple SCSI cards, so it is easiest to use a drive mechanism which has the option of supplying termination power. (This is also more reliable, as having the computer supply termination power may impose a heavy load on the power supply.) 5. The SCSI card and drive must be set to different IDs. Assuming your SE/30 has the standard configuration, then the Mac is ID 7 and its internal SCSI drive is ID 0, so the external drive can be set to any ID from 1 to 6. You should set the Apple II SCSI card to be ID 7 (jumper connecting the innermost pair - pins 8 and 9 on the 16 pin header). You cannot have both computers connected to the SCSI bus at the same time. > What is the use of the 8 jumper at the top of the card. They set the SCSI ID of the card. Exactly one pair of pins should be connected (vertically). The outermost pair corresponds to SCSI ID 0, and the innermost pair corresponds to SCSI ID 7. -- David Empson dempson@actrix.gen.nz JVernet wrote: > "David Empson" a écrit dans le message news: > 1f8q3sb.1oqio08qdu0xmN%dempson@actrix.gen.nz... > > Jerome Vernet wrote: > > > > > My AIIGS got an SCSI CARD (Model 607-0291-C, i think it's a Rev C). > > > > I'm not familiar with the model numbers, but your later description (8 > > jumper positions) agrees that this is the original Apple SCSI card. > > > > The firmware revision can be identified by looking at the part number on > > the EPROM label: > > > > 341-0112A is revision A > > 341-0112B is revision B > > 341-0437-A is revision C > I check that.

The metal sticker is the label. Don't remove it. If it doesn't have anything written on it then it isn't the official Apple ROM. It was probably burned from an image file by the previous owner. This will make it harder to identify which version it is. If you are able to boot GS/OS and it has the SCSI drivers installed, then it will display an error message during startup if the card has revision A or B firmware. It won't display anything if the firmware is revision C - it will just work. > Okay, in fact, the first partition (after driver and partition table) is a > HFS partition.

In that case, create at least one 32 MB partition at the start of the drive, formatted as HFS. You will be able to erase it on the IIgs and change it to ProDOS. > the drive is an 2.4 Gb Fireball. What 8-bit software are you intending to use with the hard drive? I'd suggest two 32 MB partitions as a starting point, but you might want more if you have a lot of 8-bit software. You might also want to set up a secondary HFS partition for use by IIgs native software and/or transferring files between the Mac and IIgs. The IIgs implementation of HFS is a little buggy (there is a patch to fix one serious problem), and it would be a good idea to avoid writing to the Mac partition from the IIgs (unless you regularly run a Mac disk repair utility over it, e.g. Disk First Aid or Norton Utilities). i.e. First 32 MB partition (must be first) for ProDOS - will contain IIgs system software (as well as applications and data files as appropriate). Second 32 MB partition for ProDOS - extra storage space. Third partition (HFS), of whatever size is convenient, which will be used for IIgs-specific files under GS/OS and for file transfer. Fourth partition (HFS), for the Mac. This will be the largest one. > > 4. Something has to provide power for the SCSI termination.

I dont know if the drive have this feature. The earlier Quantum drive models I own (LPS 240 and Trailblazer 850) both supply termination power, so there is a good chance that your Fireball will as well. The only way to tell for certain is to inspect the circuitry for the expected components: there should be a 1A fuse and a diode, probably with a capacitor, which supplies +5V to the TERMPWR line on the SCSI bus. If you don't know what to look for, another option is to use a voltmeter to check whether termination power is present with everything connected and switched on. I'd have to dig out some documentation to find out which pin in TERMPWR. > > 5. The SCSI card and drive must be set to different IDs.

Sorry, by "innermost", I meant "furthest away from the edge of the card". This is the rightmost position. (The corner pin numbers are printed on the legend, which is why I mentioned pins 8 and 9.) The card is supplied by Apple with the jumper in this position (ID 7), and there is unlikely to be a good reason to change it. -- David Empson dempson@actrix.gen.nz
