I want to use a BlueSCSI with Wifi in the P475. I try MacOS 8.1 but the Dayna SCSILINK installer do not work right with the german MacOS 8.1 I try german 7.5.3 but it also do not work (see picture) ... I have a Macintosh IIsi with this setup and System 7.1 and all works fine ... What System...

Quick and dirty fix... Unfortunately I don't have a microscope, just an LED magnifying glass. Trace on/at the VIA looking good but it isn't, there is a break. But I can't find the spots without a microscope.

Everything is there up to the vias in the picture near C127. From there to the SIMM socket, however, A1, A3, A4 and A6 are missing. @Bolle can you help with a picture of the paths?

DRAM Address to Simm ... A0,2,5,7,8,9,10,11 - ok A1,3,4,6 - no connected to RP9,10,11 ... I think it's due to defective vias between U5 and C127? The tracks are extremely thin and the vias are so small that you can't even put wire through them. I still have no idea how to fix it?

Begin to check the connections ... Rom <-> Ram D0-D3 Simm ok / U10 ok D16-D19 Simm ok / U6 ok D4-D7 Simm ok / U11 ok D20-D23 Simm ok / U7 ok D8-D11 Simm ok / U8 ok D24-D27 Simm ok / U4 ok D12-D15 Simm ok / U9 ok D28-D31 Simm ok / U5 ok ... next check A0 - A11 to the Ram.

I fix the broken connection on U8. It doesn't look good but is OK according to the tester. U11 has also a faulty pad. The error still exists. I suspect that the destroyed pad and the entire DRAM of bank A were not the original first problem. The missing 47uF C127 and C128 can't be the...

Thanks for help me ...

I bought a defective Performa 475 over eBay Germany. The previous owner unfortunately removed the onboard RAM completely and destroyed/broke the pads in the process. He also replaced the electrolytic capacitors I think and destroyed the pads in the process too. I removed the old solder from the...

Toast 4 works with System 7.1 ...

With Toast 2.56 there is no "File Menu -> Save as ..."

I downloaded the Toast Pro package and tried it out a bit but I can't get an ISO to be written. I need a step-by-step guide for dummies ...!

I don't have a SCSI burner, does it work without one, only within the Software? System 7.1 is running on the IIsi. I also have a Quadra700 with System 8.0. Which Toast Pro Version do I need?

I installed a German System 7.1 on a extra IIsi SCSI Harddrive and then created an image with Diskcopy from it. I copied the image to my MacMini with macOS and renamed it as an ISO and make a CD-R with BURN. This CD works well on my 68k IIsi but is not bootable! How can I make it bootable?

i take more tests and the Seagate ST1480N is 20% faster than the BlueSCSI (extreme Sandisk card) on my Macintosh IIsi ... On a Quadra the BlueSCSI v2 is faster than the Seagate Harddrive ...

FWB Harddisktoolkit 1.8

... a real SCSI Harddisk is a little bit ( 20%) faster than the BlueSCSI with a Sandisk Extreme SD card on my IIsi.

Thanks, I install it ...

Thanks, I will try it ...

I find MacOS 8.0 as german and install it but all 8.1 I can find are PPC (iMac) images ... I need this for my Quadra700 Looking for a Link to it ?

Yes it is the max that a IIsi SCSI Chip and system can do I think ...
