  1. Ok thank you @Dog Cow. I’d better put this quest for a working drive with the Plus to rest then. Thanks all for the tips and advice!
  2. Oh it was @Dog Cow actually about the cables and pins. Does a SCSi DB25 cable for the Plus have less pins? Do you have a picture for me that shows it?
  3. I've got some more clarity: 1. I found out that the Mac Plus also gives the fat white and black stripes when the SEAD80 drive is NOT turned on, but when the SCSI DB25-cable (non Apple) is in the back of the Plus. So @Gsbtom was right, it is the cable that is not ok for the Plus. Unfortunately I do not have an original Apple DB25 cable. I also do not have DB25 terminator, that could be a problem too. 2. @LaPorta hooked the SEAD80 up with my IIfx, with the DB25 (non Apple) SCSI cable I've got. The IIfx recognises the SEAD80, but won't mount it (see first pic). I've tried
  4. Thanks for all the input @jessenator @LaPorta and @Gsbtom, I will have a look into the cable
  5. Thank you for your tips @Gsbtom and @LaPorta, I will try them!
  6. Well the drive probably has ProDOS installed as I got it with a IIGS. So that will not work in the IIfx. I will test things tomorrow and let you know
  7. I do have a IIfx, I might give the drive a try on that monster
  8. I’ve never seen SCSI terminators for these old SCSI connectors (I know about the 80 pin terminators), do they exist? The cable is not Apple SCSI, true.
  9. It does work normally when booting from the floppy drive. I have never used a SCSI device before on the Plus (and don’t have any other then this) so I am not 100% sure this port is ok.
  10. Hi, I've got a Macintosh Plus and I want to hook it up with a SEAD80 hard disk drive. I think this drive is quite rare. This drive is manufactured by SEA Software Nederland (the Netherlands) in 1990. It probably has 80MB storage capacity and I got it some time ago with an Apple IIGS. I never got it to work with the IIGS, but probably the system on the drive is not suitable for my Plus. Question: my SEAD80 drive has got 2 SCSI ports (IN and OUT [Dutch: UIT]). I think I'll need to use OUT when connecting to the Plus right? When I do so, I have the hard drive b
  11. @gilles Thank you for pointing the 'crack' out. It is not a crack though But there WAS a crack in the adapting plastic 'cilinder' (from here on I will call it 'adapter') that connects the print roll rod to the stepper motor (see attached pics). At first I did not see it because it is black and tucked away in a shadowy place. @Franklinstein came with the right hint (see above), I glued the adapter with thick power glue to the print roll rod and after that dried, I glued it to the stepper motor. This is a risky business, you need to open up the printer and remove the circuit board a
  12. Thanks for all the replies! @gilles I don’t see cracks anywhere and don’t believe there are any. Could you point this out with an arrow or circle on the photo? The rubber rings on the print roll axis are ok. When I turn the knob of the print roll, the paper moves upwards/downwards. @Franklinstein I have to try this trial and error method you suggest. The axis of the stepper motor itself does move when unplugged. So it is not stuck. Surprisingly there are no gears whatsoever. The axis of the stepper motor just fits in the hollow axis of the print roll. No spe
  13. Hi, I've just brought my Apple SilenType printer back to life yesterday, hooked up on my Apple II Europlus. Amazing it still prints. There is just one problem: it won't move the print roll. So lines are printed on top of each other. I suspect a defective electric motor on the print roll rod. Does anybody here know what the problem could be?
  14. Crazy stuff. I put everything together and all is ok. Probably it was the connection of the long pins in the red socket after all. Relieved here! Thanks!
  15. Thanks for helping! I’ve removed the top and disassembled the keyboard. The long pins appear to Ben in the red socket. I’ve checked the alps too. They are alright, they always were. A friend of mine mails me and thinks the duplexer chip could be the problem. No idea what that means or where it is located though.
  16. There are no stuck keys. Strange thing is: it doesn’t happen with the following keys: 3 7 W O S G K ; C / When I am in ProDOS List Directory, all keys function well. See picture where I type RRR without underscores. When en going to AppleSoft Basic, it goes wrong. See second picture. What could it be? I do have a numeric keypad on my Apple II, and when I use it it does not give any underscores. Strange!
  17. Hi, my Apple II Europlus types an underscore after each character. What could be wrong? Used systems are DOS 3.3 and ProDOS 1.01, both with the same results. Help is is very much appreciated!
  18. I've managed to unplug the plugs from the Logic-board. It is clearly to see that there is corrosion (the light brown 'heaps' around the capacitors), see my picture. Two questions: 1. I've also made a picture of the 'orange-brown golden fingers strip' that just slid out of the plug when I lift it a bit from its socket on the Logic-board. The strip has some 'bleeding' on or in it...would that be a problem? 2. I am no expert in replacing capacitors, this will be my first time. Is the soldering iron in the picture good enough to do the job? And should I start at the ba
  19. Here a photo of all the cables connected to the Logic board. The left plug was the only one I managed to unplug. A bit strange though: the golden fingered flat strip just slid out of the plug… All the other plugs I just could not get loose. Unbelievable how stuck they are! What’s the clue?
  20. @archer174 Ok, that’s good news. I do have great difficulty in loosening the yellow wired cables from the Logic board. I don’t want to damage the cables and sockets. What should I do best?
  21. I've opened the CD SC Plus (a hell of a job!). I have not managed to get the plugs out of the Logic-board, they are mighty stuck and I've read about how vulnerable they are. When I look at the back of the Logic board, I see a few very slight corrosion marks. Does anyone of you @bibilit @archer174 recognise it as the capacitors being the problem? BTW, the laser lens looks nice and clean. @techknight How do I know the laser assembly is the problem?
  22. This is what I found in the Apple Service Source document of this device (http://tim.id.au/laptops/apple/misc/applecd_sc.sc_plus.pdf): (Troubleshooting/Symptom Charts - page 2) : "Red LED does not light when you insert the caddy 1 Exchange drive mechanism. 2 Exchange LED board. 3 Exchange power supply." The red light does indeed not light. It is very probably not the LED board and it is not the power supply. That leaves the drive mechanism (or capacitors) as faulty, as you guys said. I will open the thing up shortly and post photos here!
  23. Hi techknight and archer174, thank you for your replies and insights! I am not a technician I'm afraid (although I can mend a few things :). How do I see that the laser assembly is not ok anymore? Replacing this item will not be possible anymore, since the device is 25 year old I guess?
  24. Hi, my AppleCD SC Plus (M3021) is unable to mount cd's or cd-roms. It is hooked up to a Macintosh IIfx with OS 7.5.3, has the proper installed software and is (I think) neatly terminated in the right manner (it is the only externally installed SCSI-device and has the terminator in the upper SCSI-slot, and the SCSI-cable which is connected to the IIfx in the lower SCSI-slot). The CD-ROM drive (which is actually a Sony device) is shown with ID 3 among other SCSI-devices, the harddisk and the CPU (please see pic below). When I insert the cd-caddy loaded with a cd or cd-rom, it starts
