Hello folks, thanks for the replies. I removed the PDS expansion, all RAM and the cache module, reseated the ROM module. No SCSI stuff connected. The CPU thermal paste was crap, for the early testing I did not reseat the cooler yet. For sure, I did not operate it for more than a minute. With...

Hello, I recently got a 6100/66. It is really unstable, it only boots with zapped P-RAM (with fresh battery installed!), sometimes it just does the chime and brings up no picture (as said with a good battery) sometimes it reboots during boot up or even when running Mac OS. I managed to install...

Hi, now I'm stuck with the next issue: Networking. I've installed PCSetup 2.17 on the Mac side (on OS 9.1 english) and Windows 98 SE on the PC side. I've also installed the second disk of PC Setup 1.6.4 and got the MacODI drivers loading correctly. I've installed the Win98 legacy ODI driver as...

It's always the same drama, floppies work best if they are emulated :-( I found a bootable harddisk image to get the initial setup of my disk image done and installed it this way. https://modelrail.otenko.com/category/apple/page/2 BTW: fdisk.exe from MS-DOS cannot set MBR and bootable flag...

Hello, on a fresh installed Mac 7300 (MacOS 9.1 with PC Setup 2.1.7) my DOS compatibility card is unable to boot from the floppy drive. Already tested three different drives with a DR-DOS 7.03 floppy which is known to work for different real PeeCees. When I insert the floppy while the PC...

Hello together, i'm currently trying to get my 475 into the LAN but it fails to enable both network cards which I have. The Asante EtherTalk  driver 5.6.1 which I have states that it is not compatible with the 475. Is there any way to get it working. The ADLS tool detects the card and displays...

Hi, I finally did the mod. I added a Samsung USB wall charger into the case of the power supply and added two additional wires which connect to the batteries on the motherboard. I don't care for the clock batteries, no machine in my collection has them because I'm too afraid to loose one again...

Hi, I wanted something without batteries. My motherboard already has this dual battery circuit with an extra cpacitor. But it's good to know that the batteries are switched in series. Is the PWRON pin on ADB switched against ground our +5V for powering the system on? Greetings Florian

Hello all, did some of you ever build a work around for the ugly standby battery in the Mac II's? Did industrially manufactured solutions ever exist which are worth for a replication? In the case there would be enough space to add a 5V power source (e.g. beside or beyond the harddisk mount)...

yes the monitor did the trick but this is not my studio monitor, it's an ordanary PeeCee monitor with a VGA plug.

Hi all, thank you all very much for the help, this repair was very successful. To be honest, I did not believe that the fixing of a such complex motherboard it possible. But it is. Cool. Best Regards Florian

Hi again, a pic of the video card is here: https://www.hidrive.strato.com/share/x7sd5uwnbe It's a TFB Controller 20R6A The caps look OK is this one of those which need the recap? Does this produce RGB? Where can I find a pinout? What are its frequencies? I have a Sony studio monitor which I...

Hello folks, when I place RAM in all slots now, I get the good chime. When I add RAM only to BANK A I still get the dead chime. But the connected monitor only turns on and still no picture. Do you have any suggestions what to check next? It was no keyboard/mouse connected. Macs do not need...

Hi all, I recently got some of those MPL units from scrapped military PCs: http://www.mpl.ch/t2332.htmlThey should behave like SCSI disks. So I tried to use one together with a PCMCIA to CF-Card Adaptor (which is just something mechanical, the bus protocol is the same) with my classic computer...

Hi all, I would say networking is the best option too. I got it working between my IIsi with a Asante NUBUS card and the iMac G4 (lamp) of my girlfriend running OS-X 10.4 on the lamp and Classic 7.5.5 on the IIsi. This page is a great resource: http://www.applefool.com/se30/ You can get the...
