I have a tall 128mb simm in my 475 that conflicts with a processor upgrade card. There would be a lot of room if the ram socket leaned away from the processor- are there sockets that lean the opposite direction? I can’t resolder existing socket backwards, pins would be reversed.

I’m having an odd issue with a IIci using internal video. B/W,16,256 color all work. 4-color works, but blue pixels crawl, bleed and flicker. Does this point to a ram issue, or specific to video output IC?

I’ve seen a number of threads on floppy issues, but not specifically formatting issues. Drive seems to work fine for read/write. Logic board recapped. I found a few bad floppies recently, tried to format, failed. Tried to reformat several new floppies, also failed. It goes all the way to...

I have an Interware 17DU I’d like to use with a Quadra 605/LC475. The card has an LC PDS but was marketed for other machines with PDS than the LC series (aio, some other macs with LC PDS). From what I can find, they marketed the similar 17iL series for the 475. Is it possible to use the 17DU in...

I’m trying to hook up macs using DIN serial ports to DB25 using Lantronix UDS1100 to bridge over ethernet. I can’d seem to find the correct cables and pinouts. Sites have very different pinouts shown and three different cables I’ve bought all are pinned differently and don’t work. What is the...

I’m replacing the stock MDD power supply, and noticed the latest ATX options don’t supply -12v. I realize this runs to the PCI and possibly modem, but in practice is this power bus actually used? I am using a g-port clone serial port, not sure if there is a boost converter…

Building a IIci system with bluescsiV2, onboard scsi is very slow. Looking at nubus scsi (fwb jackhammwr, atto SEIV, others?). I’m running system 6 on this machine, any experience with this combo? Jackhammer manual says system 6 is not supported but should work, Atto manual says nothing about...

I have a G4 MDD running ATI and NVidia video cards. Using 1920x1200 60 Hz displays through dvi and notice frame tearing in most games. Is there a way to enable/force vsync at a system or driver level?

I am working through issues on one of these ti4600 mac cards. It boots, but rarely gets to a mac desktop. The one time it was stable enough, I switched to 256 colors and had a lot of randomized noise on the screen. Only the dvi port works, nothing out adc. There are a few missing caps as well...

Surprised I wasn’t able to find anything on this- I am trying to run a serial video capture peripheral that is verified on an SE, but captures digital noise on a quadra. It was suggested it is out of sync due to software that might be tied to clock speed like some old games that run too fast...

I have two Koala MacVision serial capture boards, hooked to quadra 605 running 7.5.5. Both capture a single frame of wavy noise, regardless of the video input I try. Recapped one, same result. These are different internally, with one comprised of discrete logic/opamps. I’m trying to determine if...

I have two PCI cards that do not allow my MDD to sleep in MacOS 9- Adaptec USB and Keyspan serial. Going to sleep, computer immediately wakes back up. Is there any known workaround to allow sleep for PCI cards like this?

The slow scsi bus in the lc to q605 seems to be the limiting factor for system performance. I found an apple doc on pds dev stating a scsi pds card was possible- was a faster scsi bus pds card ever made for these machines? In addition to faster drive access, more headroom for rascsi future...

Quadra 605 has been solid for months. Forgot to reinstall the microSD card in Bluescsi, flashing question mark on startup. Turned off, reinstalled, startup chime, gray screen, cursor freezed after 1 second, doesn’t boot. Removing everything I can from the system, pram/reset switch doesn’t help...

Until recently, this MDD dual 1.4 would sleep reliably. Recently when I put it in sleep it wakes back up before the fans have the chance to spin all the way down. Trying to backtrack what has changed. Have you encountered this behavior? Any ideas of what to try? Already disabled wake for network.
