The Card Works, but he has no software for it. (e.g. Unable to change the setting, exept via the DipSwitches) Not good as he is new to the GS. and his son plays games on the GS. Part 1 ------ The Guy got the Zip off some-one and they never gave him any software for it. e.g. the CDA or the Init. So what I am looking for is; if you know _if_ the software is on any of the A2 archives, and which one`s. And if there are any conflicts between the ZipGS and the Apple HS SCSI card I should be looking for . So far I manage to get the CDA (ZIPCDA v# 1.3) but have not been able to find ZIPGS.Sys / ZipInit/ ZipTalk (Only needed if your STILL using LESS than System 6)/ Zippy or ZipFix (You should all have this installed.) ): The disk(s) that came with the Zip would be of use (: Part 2 ------ Just for Fun, I have a AppleShare Server 3.0.3 running on my MacSE and booting with no ZipCard On _MYGS_ works fine (: I would like to try getting my GS with his Zip to boot from my AppleShare Server 3.0.3 before I reinstall it in the guys GS for his son to play games with ): So far I have not been able to get it to do so ): If I boot from a floppy (No ZipCDA) installed. I can connect to my Server, but if I try to boot (No ZipCDA) off the server directly, it fails ): Any suggestions! _HISGS_ ----- GS Rom 1 4M 1 3.5 System 6.0.1 Slot (7) Apple HS SCSI card Version # =(unknown) _MYGS_ GS Rom 1 1.7M 2 3.5 1 5.25 Slot (1) My Card Slot (7) AppleTalk appleshare 3.0.3 ZipGS Switch Setting: ------------------- Legend ------ sw1 = DipSwitch(1) sw2 = DipSwitch(2) on = enabled to enable Function off = Dis-able Funtion Current Setting Via DipSwitches. -------------------------------- sw1 (1) =on (2) =off (3) =on ***NOTE*** Tried this in the OFF setting as well.

(I have compiled this in regards to AppleTalk and the ZipGS)*** *NOTE* I am not SURE if there is any differance between the ZipGS version 1.0.1 and version 1.0.2 in regards to the DipSwitches layout/funtions. e.g. does SW1(1) on v 1.0.1 have the same funtion/layout as v 1.0.2 (: and so on. * Snip-its * from David Empson / Todd Whitesel / Steven Nelson * ***David Empson*** 1-1 Cxxx/Dxxx Cache Disable. Leave this switch ON (option disabled, i.e. enable caching of Cxxx/Dxxx). 1-2 Joystick Delay. This will slow the computer down whenever the joystick is accessed (it is timing critical). I usually leave this one ON to avoid the delay - most joystick programs have to run in slow mode anyway, so this delay in useless. 1-3 AppleTalk Delay. This switch should be set ON unless you are booting from an AppleShare server, or using AppleTalk with System 5.0.4 or earlier. *** David Empson ENDS*** ***This bit from Todd Whitesel regards AppleTalk Delay*** ---------------------------- AppleTalk or Interrupt Delay should always be disabled. The desktop will run much slower if you enable it. (requires CPS Follow to be enabled for the fix to work.) snelson@news.uiowa.edu (Steven Nelson) writes: >Todd, why should everyone have Appletalk delay disabled with a ZipGS? Because it saps performance every time an interrupt occurs. The Appletalk delay was originally called the "Interrupt Delay" but they renamed it at the last minute because (somebody) actually tried an 8/64 on an Appleshare network and it dropped packets like crazy. With "Appletalk delay" on, every time an interrupt occurs your Zip will disable acceleration for 5 ms, just like it does with the paddles and the speaker and the others. This is a significant effect because with VBL interrupts going you have one every 16 ms, so your Zip spends nearly 1/3 of the time not accelerating you. Why this "fixes" appletalk: in system 5 and earlier (including the ROM appletalk code), there are software timing loops which assume 2.8 mhz operation. As you speed the system up, it gets more and more likely to drop incoming packets because it thinks they are being sent too slowly to be correct, when in reality the appletalk code is timing out too fast. Why the Appletalk delay is not a complete solution: a full-size Appletalk packet that you'd get from a file server takes about 14 ms to transmit. The Appletalk delay covers the first 1/3 of the packet, the VBL interrupt covers at most another third of the packet, but nothing is guaranteed to keep acceleration off for the whole packet. If you speed the Zip up more, say to 10/64, it starts dropping long packets no matter what. This latter problem was why I originally wrote ZipTalk. It required a slot delay to be enabled (in, say, slot 6 or 7), and before each appletalk packet was received I tweaked that slot -- slot delays are 50 ms, so the Zip stays unaccelerated way past the end of the packet and everything works. (I also patched packet sending, to be safe.) In system 6 Apple fixed things correctly in the appletalk drivers. I removed the code from ZipTalk and released what remained as ZipFix. As of 6.0.1, the cursor flicker problem was fixed by apple in the control panel, so now you only need ZipFix for the GS/OS SET_SYS_SPEED hook, which nobody seems to use. snelson@news.uiowa.edu (Steven Nelson) writes: >change the AppleShare one to start up normal speed, and have the init >(?cdev) turn on the Zip AFTER bootup started.) Thanks for any info you >can share This is typical, because the bootup code doesn't know how to cope with the ZIP. Once you have system 6's appletalk drivers loaded, you don't need the special ZIP settings any more. Todd Whitesel toddpw@ugcs.caltech.edu *** Todd Whitesel ENDS*** *** David Empson *** 1-4 Counter Delay. This switch should be set ON. Its only documented function is to allow one of the IIgs self tests to pass, but a later one will fail anyway. 1-5 CPS Follow should always be enabled. If you disable it you will have problems with Disk ]['s and System 6's AppleTalk driver and anything else that expects the Zip to slow down to 1 mhz when the GS is instructed to slow down to 1 mhz. *** David Empson *** *** Todd Whitesel *** For instance, border text demos (like the FTA XMAS demo) won't work if you have this disabled. Expect weird things to happen if you play with this one. Todd Whitesel toddpw @ ugcs.caltech.edu *** Todd Whitesel ENDS*** *** David Empson *** 1-6 Disable. The card should normally be enabled (switch ON), but you can disable it if you want to run some "fast" mode games, for example. 1-7 and 1-8 control the cache size, which must correspond to the installed RAM chips. The cache uses matching pairs of TAG and DATA RAMs. The supported cache sizes are 8k (1-7 ON, 1-8 ON), 16k (1-7 ON, 1-8 OFF), 32k (1-7 OFF, 1-8 ON) and 64k (1-7 OFF, 1-8 OFF). 2-1 through 2-7 control slot delays for each slot from 1 to 7. Set the switch OFF to enable the delay for the corresponding slot. This is generally only needed for a small number of cards that are speed critical but not IIgs-aware. 5.25" disk interface cards are covered by the CPS FOLLOW option (1-5) if they are in slots 4 to 7. I have found that it is necessary to enable the delay for slot 6 when using a 3.5" drive connected to the IIgs disk port. There are a few rare cases in which a long timed operation is performed in fast mode, and the ZIP throws the timing out unless this delay is enabled. In my case, I had some strange disk errors with certain disks until I enabled this delay. 2-8 Speaker Delay. This causes the IIgs to slow down whenever the speaker is accessed directly, allowing sounds to come out normally. *** David Empson ENDS ***
