Hello,
I just joined this forum and this is my first post.
As an introduction, I am not new to retro/vintage computers and have a few. Most of these were purchased new by me back in the day, including systems from Sun (SPARC 20), SGI (Octane 2, O2), NeXT TurboColor, and various Mac’s. My Apple IIGS (ROM 3) was recently excavated from storage to be brought back to life. I am a bit rusty with Apple II operations - but it’s slowly coming back.
For the IIGS, I installed a new battery, upgraded the power supply (ReActiveMicro) and added their MicroDrive Turbo in slot 7 (DMA enabled) and have GSOS 6.0.4 installed. The system has the Apple HS SCSI card in slot 1 with DMA enable (it is configured as ID 7). I am attempting to get a CDROM working with the SCSI card. There are no other SCSI devices connected.
I have tried both the AppleCD 300e (AppleCD 300e (Sony CSD-7611, 4X CD-ROM, Mfg. June 1995) and the AppleCD 600e (Matsushita CR-504-B, 4X CD-ROM, Mfg. August 1995), and they both had the same strange behavior.
After connecting the 300e (terminated, ID 3) and booting GSOS, I first checked in Media Ctrl panel and saw the CDROM port available in the ports section of the control panel and selected it along with AppleCDSC to configure the media channel. I am aware that neither the 300e/600e support CD audio, so I was’t expecting that to work. Nevertheless, I opened the CD Remote DA (no errors) and attempted to play an audio CD which did not work. I then inserted a data CD - which I expected to work fine, and it indeed mounted on the desktop. I was able to look around at the files, then closed the Finder window and ejected the CD. This is where it gets strange. The Finder became somewhat unresponsive. The system was not locked up; I could move the mouse around, but could not interact with any menus, drive, etc. I had to reset.
When the system rebooted, I could no longer mount the data CD that just worked a moment before. Likewise, the CDROM device was no longer present in the Media Ctrl panel, and launching CD Remote produced the error, “The AppleCD SC Drive cannot be found...”
I shut down the system, connected the 600e and reproduced exactly the above sequence; the 600e worked exactly once, after ejecting the data CD the system became unresponsive and after resetting, the 600e was a distant memory.
I attempted to get the drives working with DMA disabled on the SCSI card, but no change. I also backup my system folder and installed the GSOS drivers from the HS SCSI card utilities disk - which as I expected made the system unbootable.
Booting to ProDOS, several SCSI utilities correctly identify the SCSI card, and it passes the diags included with the utilities disk.
I have since verified that both drives work on one of my other retro system without issue, so the hardware/termination/IDs are all fine. I've also tried using different SCSI cables and terminators. No change.
Any ideas as to what might be going on?
