: Greetings. I am confused. I was given an Apple IIGS system recently, : and I'm beginning to fiddle around with it (see my two recent posts : where I declare my newbie status). The system came with an Apple II : SCSI Card and a 42MB hard drive with System 6.0.1 installed. As I : indicated in my first post, I was encountering a $0201 error when : booting 6.0.1 from the hard drive. I have been unable to clear this : error even when I attempt to boot with Desk Accessories turned off : (holding down the shift key). I have a floppy drive and System 5.0.4 : disks (I don't have 6.0.1 on floppy). I can boot into the floppy just : fine, when I set it as the startup disk.
Your problem is definitely insufficient ram. But, that can be remedied by purchasing one of my 4 MB ram cards. for $44 plus postage of $3.85 in the US, and $8.70 everywhere else. Done. : I am learning that the 0201 error is related to insufficient memory-- : either physically, or through some software glitch, made : inaccessible. I have taken the suggestion from this list and some : online FAQs to try to determine how much RAM I have. The Control : Panel suggests I have 512KB. But this is what is confusing me on two : counts: 1) the system as I received it was connected to the boot-able : hard drive running 6.0.1--I have learned that it is not recommended : (or even possible?) to run 6.0.1 on less than 2MB RAM; 2) the IIGS : has an Apple II SCSI card, and the manual I have says the card won't : work on a IIGS with LESS than 768K of RAM. See Above. : So, how much RAM do I really have? And is it possible that some of it : has gone bad? I am assuming that there is 256KB on the mobo (4 x 64K : chips of "Standard RAM"). I confirmed this by checking the Control : Panel with the expansion card removed. Sure enough, 256KB. The : expansion card has 8 chips of Texas Instruments TMS 4256-15NLA. Does : anyone know what the size of these chips are? I couldn't find that : info online. The 6 other chips appear to be controllers (e.g., I : discovered that a 74F04 is a "Hex Inverter"). If, however, those 8 : chips are only 32K each that would be 256 for a total of 512. But : then again, how is it that the computer was apparently successfully : running a SCSI card and a hard drive that booted into 6.0.1? The ram ICs on the acrd are 256 x 1 bit and 8 will give you 256K. With the 256K onboard, you have a total of 512K, not enough to run anything correctly. : Since I have you here, I have System 5.0.4 on floppy that appears to : work fine to boot the machine--though occasionally I have also : experienced a 0201 error when trying to open a Control Panel from the : Finder. Should I even be attempting to us GS/OS with 512K of RAM? I : understand 5.0.4 doesn't require as much RAM. Again, see the first part of my reply. That will solve this whole mess. : Thanks again for your help. This is very interesting, though I feel : like I'm on the learning curve! You think this is a learning experience?
