    Techworks network card drivers for SE/30

    It should work with the standard driver that comes with the system software. The card has to in the machine while the system software is installed otherwise the drivers won’t be installed.

    SE/30 Garbled screen

    Could be caused by an intermittent connection of an address line on one of the video address muxes (chips UA8 to UD8) I had this exact symptom on one of my SE/30s and it took me ages to find because all address lines buzzed out fine on the first two tries but it was open when I went through everything a third time. Also could be one of those chips is on its way out.

    How bad is the damage?

    Totally fixable. Looks like it wasn’t sitting too long with the gunk doing its thing at eating away on the board. Lets hope the RTC chip is still good, getting replacements for those is an issue and requires another Mac as donor.

    SE/30 with Vertical Pinstripes

    It could also be a stuck input on UE8. But as said I would check the address lines first.

    SE/30 with Vertical Pinstripes

    Ah... Well then check connectivity on the address lines going to the video address muxes (UA8 to UD8) One of them will be broken. It’s also possible one of the muxes itself has a stuck input or output but I’d start checking for connectivity.

    Mac SE/30 parts

    You will have to fix a lot of broken traces besides replacing those components. There is visible damage to some of them and as soon as there is visible damage there will be more hiding from what you can see. The SE/30 will start without the RTC/PRAM but you won’t be able to boot from SCSI without it. A RTC chip from the SE or any other Mac II that uses the same form factor will work as a replacement.

    SE/30 with Vertical Pinstripes

    If you get stripes UE8 is working fine. The stripes are the default content of the VRAM chips at boot time. Seeing them means the VRAM data makes it to the screen (which is the job of UE8 - taking in parallel data from the VRAM and sending it out serialized) Your machine is most likely having issues reading the ROM. Do you get any chimes when turning it on?

    Xserve G4 L3 cache failure

    Cache failures seem often to be CPU related, so swapping the cache chips itself is probably not going to help you. I have been testing a few CPU modules that reported L3 cache failure and the L3 started to work again after swapping the CPU. As MDD/XServe modules are cheap and easily available it is not worth it to even attempt this repair as you would need another CPU card as donor anyways.

    Macintosh Portables Dead

    You are going to have to strip out the logicboard and hook up the battery terminals to a bench powersupply (you have to do this the correct way or you are going to kill components on the board) to be able to do any useful troubleshooting. Replacing the caps and cleaning the board really good is obligatory before any further troubleshooting can take place. Look up techknights youtube videos on the Portable. They are a very good starting point. Check for broken traces around the Hybrid and in all places where caps are sitting. It’s common that stuff breaks around there.
  10. That Big Picture adapter is not meant to be used in the LC. The video card you got there is meant to be used together with an accelerator that has the correct 64pin connector. If you want to use it without an accelerator you can do so by using the adapter you have. If you plug this thing into an LC all it will do is release some smoke.
  11. What is that tool in the screenshot that shows the oscillator frequency and all those values? Is this part of the SuperVideo panel? Never seen it before.

    SE/30 new ROM and other things

    It can run more modern software. (which most likely runs in 7.1 as well though after installing Drag&Drop and Thread Manager extensions) Other than that I don’t see any advantages. It is more resource hungry so I stay away from it on 030 machines. Maximum HFS partition size is the only thing that could be a factor to choose 7.5.5 (supports 4GB partitions) over 7.1 (2GB maximum partition size) I don’t run 7.5.5 on 030 Macs as I have yet to come across a piece of software that wouldn’t work on 7.1 and most of my drives are either smaller than 2GB anyways or are split into several partitions anyways for organization so I mostly don’t care for the 2GB limit.

    Baroni’s Collection

    Needs new caps. There might be more damage in the power management circuit which prevents it from turning off correctly.
  14. It does. As said in 24bit mode I don’t get any hits on the 32bit address range and /FC3=high (unless FC0..2 are high which means it’s not an actual call to the card but some kind of interrupt handling. In 32bit mode I don’t get any hits on the 24bit card range (and /FC3=low) I can dissect the card once I get back from my two week vacation in Japan and see what the address decoder on my card does if that’s of any interest.
  15. Good point. I only have an original LC here for testing which lacks the MMU hence no remapping there. This might be why I can see card accesses in 24bit as well as 32bit range with the LA depending on what is set in the memory cp. As I said in the other thread that’s the way the LC does it so the card has to be able to decode both ranges. I can take a closer look at the card itself and buzz out the connections and crack open the decoder GAL to see what it is actually doing. Might be worth a look. If the SE/30 only addresses cards in 32bit mode that would make things easier indeed, as we wouldn’t have to check the whole upper half of the address bus to see if it’s doing a 24 or 32bit access. One more thing to check on the list.
