  1. I am trying to figure out what might happened to my RasterOps/24 card. When I got this IIci it was working. Then, when using my External SCSI Zip drive the computer froze. Since then I wasn't able to boot the machine with the RasterOps card. It hanged on the grey screen. Today I got a second monitor and decided to hook up the RasterOps again. The computer/system recognizes the two monitors but it I move the mouse to the one with the RasterOps the mouse pointer gets stuck and won't move. I am really amazed with this. Did this happen to anyone?
  2. The IIci yes, it has been recapped.
  3. Hi guys. I have this Mac SE that was running fine. But its HD stopped like many others I had here due to time, if think. I put an replacement and started the system (as I usually do with all my Compact/Classic Macs) using my external SCSI Zip Drive using System 7.5.5 Started the formating of the HDD and at the end the System rebooted. I tried again with different softwares and the same happened. I fired it up today and used an System 6.0.8 disk and instead of resetting the mac, I got an error, Address Error.... Tried to format a floppy and the same happen. What would cause this, bad RAM? How can I test it? Cheers!
  4. Hi guys. I have a Mac IIsi board that is not working. It boots to the grey screen without the mouse pointer or making the boot chime. It does some rattle noise on the speaker though. It was this way even before removing all the capacitors, washing the board (let it dry for some days) and recapping it. Its PSU, memory and HD boots fine the other Mac IIsi I have here. Any hints? Thanks!
  5. Hi guys, This card came with an IIcx and I have no clue how to get it working (mostly about the DB9 pinout), if a control panel is needed or how can I attach a DB9 monitor to it. Here are some pictures: Thanks in advance.
  6. Hi all! I have a Mac SE with this board inside. It was a surprise to find it. But the original HD is gone. So, in order to get it working I need some sort of 68000 extension to enable it. Anyone have it? Or know where I can get one? Cheers!
  7. I have tried some extensions but none at all made the AoX work. Still in the pursuit.
  8. Have finished the recap. Removed the caps, washed the board, let it dry for two days, recaped the SMT and Axials. Now I have sound but with the RasterOps I still can't boot, same sad mac error 0000000F 00000033 And it was working...
  9. Hi Guys, I just got an Mac IIci. And I am running into a problem. Lets see if someone can help me. It was stored for many years as the son of the previous owner told me. I took a quick look inside and noticed one of the RAM sockets has the locks broken so it was loose. I used a small eraser (yes) and kept it in place. I will buy a socket to replace it. Also I noticed the computer has a RasterOps 24si card. So I plugged the monitor in it and started the computer. It loaded the OS from the harddrive but I notice there was no "chime" when the Mac booted. So, my previous experience with a Classic II working without sound = recap. I used it for a few moments, just to check some things then let it aside to do my other stuff. A few moments ago I decided to backup the harddrive so I connected my SCSI Zip drive and fired up the machine. It booted and when I returned with the disks, it was frozen. I restarted it and now the problems began. After the RasterOps Logo I got an grey screen. I waited, waited, waited, then restarted. The same happened for 4-5 times, when I decided to plug the monitor on the onboard video. There I saw a sadmac (forgot to get the code). (EDIT) Code is: 0000000F 00000033 I removed the RasterOps card (even it still shows its logo when powered up) and I got the system running again. Decided to try the RasterOps again and now I noticed another problem, the computer won't power up, like a failure on the power supply, it makes a sound like a relay was clicking but no power. Removing from the outlet for a few moments did the trick but again no system after the gray screen. Tried the RasterOPs on other slots but no luck. So I removed the RasterOps again and after a few tries (the power supply click - no power) I got the system and started the backup. I thought it was a coincidence the RasterOps not working just after I used the SCSI ZIP or it may already a problem on the Board so the RECAP and cleaning is a must? Or the card just died? And about the PSU? What I can do? Cheers. (EDIT 2): Noticed the PSU problem is gone if the external SCSI Cable isn't connected.
  10. Yeah, will do this. But I am concerned about the RasterOPs card. Hope the recap fix all this.
  11. Hi all! I just got a beautiful Classic II! (ok I know I need to recap it as soon as possible) Turned it on and worked. But I opened it to do a quick checkup and probably I was the first person to do it. It had no marks inside at all, everything was in its perfect position. Just some dust but not that much. I looked at the mainboard and there is no sign of leakage but as soon as I return from my one week trip to Rio de Janeiro I will recap it. I just washed the board, let it dry for a couple of days and it is still working. But I noticed it doesn't do the chime startup sound. There is no sound at all. Even inside the system (7.0.1). I tried to check the volume using sound control panel but it gives an error message: Maybe a faulty IC? Or just recapping will do the job? And I have a question: I networked it with my Beige G3 Desktop running OS 9.2.2, using a simple printer cable via parallel localtalk and was able to receive some files from it. The question is: can I browse the web on Classic II using this setup, the G3 providing some sort of bridge between its ethernet and the localtalk? Thanks in advance.
  12. I hope some of friends here on the forum have one and could share. I'm thinking about trying other 68k 16mhz extensions to check if it enables the card but I don't know any other ones.

    AOX DoubleTime 16 - Info needed

    Hi Guys, now I had time to use this Mac SE and noticed it is too slow. I ran speedometer 3.06 and just got the base score (1.00). With or without the AoX Card. May it need an extension to work? And why is the SE too slow? Cheers.

    AOX DoubleTime 16 - Info needed

    Hello guys. I bought a SE and it came with this card and also 4mb RAM upgrade. I tried to get more info about it (mainly about the extra video port) but I only found a leaflet about its main characteristics. Do anyone have it? Manual? Cheers
  15. Hi Guys, I am still trying to fix my SE/30. I was able to get a possible replacement for UE8, 74ALS166. I installed it but still no boot. Is it a replacement for LS166D ?? Thanks in advance

    SE/30 - Is 74ALS166 a Replacement for UE8 (LS166D)?

    I have a working SE/30 board and did a test to try to narrow the problem. If I remove the RAMs and try to boot, this working board chimes and give me the same pattern as the defective one on the screen. With the RAMs but without the ROM SIMM the boot is the same as the defective. So I may need to check if there are any broken traces leading to the ROM. Which usually fail in this case (near LS166 - UE8) area?? This board worked for a while before it crashed. It made a sound like a crackle and stopped working and I saw how destroyed was LS166D. I recapped it and now was able to get this ALS166. Thanks for the help.

    SE/30 - Is 74ALS166 a Replacement for UE8 (LS166D)?

    No it doesn't chime at all. The board is recapped and the tracers for UE8 are good. I couldn't just find where is the CLOCKIHB signal (pin 6 of UE8) but I think it is grounded. No I get no chime. There was no battery leak. I replaced the caps near the ROM SIMM and RAM banks. So, I may still have a line broken there, mostly near ROM? Thanks for helping me.
  19. Hi guys, I bought this SE/30 as is. When I first started it I got this screen: Then I opened it up and pressed the socketed ICs down and it showed me the simasimac screen and then, turning it off and on again, it worked. I was able to use it for some time, tested my other Mac HD on it, tried to see if the floppy was working, but sometimes the screen went black and the same pattern above appeared. Waited a little more and the mac screen was fine. I tried to move the mac (still on) to a better position on the table and was able to see this affected the screen. I continued to use the Mac for sometime but the problem was still happening. Noticed that if I knocked the mac on the site (the one with the analog board) the screen returned to work. I thought the problem was on the analog board. I removed the logic board and with it out of the case I tried to repeat the knocking to see what happened: nothing. I realized the problem was on the logic board. If I knocked it on the same side, the screen changed but now I was able to hear some noises coming from this area: (this isn't my board picture, just got one from the web as example) Then the board just gave me the pattern from the first picutre. I noticed the + leg of C2 was hot. I replaced it but nothing changed. I saw the board was hit hard with capacitor leak and LS166 was very corroded. I used isopropanol but the damage was so severe it lost 3 legs. I removed all capacitors, washed the board, let it dry for 3 days, recapped it and replaced LS166. Now I only get the simasimac screen. I tested the memory and ROM on another SE/30 and they are fine. Guys, where should I look or test to get it working again? Thanks in advance.

    SE/30 simasimac/lines/no video - Trying to fix it

    Here are the pictures of the board, without the UE8 (LS166D) IC

    SE/30 simasimac/lines/no video - Trying to fix it

    I am struggling to buy theses ICs here in Brazil. I want to replace all these near the UE8 just in case. But I can't find them. As soon as I arrive home I will take pictures of the board. I can check this track near C2. Also I think something is wrong with the transistors Q1 and Q2. I heard "noises" prior to the motherboard failure near C2 area.

    SE/30 simasimac/lines/no video - Trying to fix it

    Hi, thanks for the answer. I have tested the ROMs in another SE/30 (and its on this SE/30) and they are fine. Yes, I have another set of working RAM (and one set in a working SE/30). Tried with no luck. Yes, I tried the reset but nothing happened, just a screen blink. Thanks again.
  23. Are the SE/30 ICs LS393D, LS166D and F253, all SOIC14 type?
