| Posted by: uniserver on 2013-01-09 21:59:52 did you replace the big 220uf's and 470uf's? | |
| Posted by: mcdermd on 2013-01-09 22:00:25 Yep. And a 10uf, 16v and a 1000uf, 16v | |
| Posted by: uniserver on 2013-01-09 22:07:52 i'd pop out any chip that is socketed and re-insert, those days of the Apple III, remind me those removable chips can settle funny, + because it sounds temperature related... | |
| Posted by: mcdermd on 2013-01-09 22:13:37 Yeah, I was thinking about that too. Good advice. I had to pull, clean and reseat every chip on one of my Apple ///s before it ran reliably. | |
| Posted by: mcdermd on 2013-01-10 12:25:04 I think I have it running well now. So far it has powered down and restarted several times today without incident. Since it was being fickle about booting, I have reseated the processor and co-processor, all RAM SIMMs, the ROM SIMM and replaced one PRAM battery that was showing 3.5v instead of 3.6v. I also had to clean and lubricate the floppy drive to get it to read disks properly. My fingers are crossed that it will remain a solid performer now. | |
| Posted by: uniserver on 2013-01-10 12:35:28 :-D its solid now… 🙂 great news man! | |

| Posted by: mcdermd on 2013-01-23 22:50:31 Picked up a few PowerBooks lately - a 190c, 5300cs and some parts to complete my 3400c. | |
| Posted by: TheMacGuy on 2013-01-23 23:41:03 Nice! I need to find a parts 5300 for that damn trackpad cable for the 5300cs. | |
| Posted by: CC_333 on 2013-01-24 01:21:38 Hi, I have a scrap PowerBook 190cs (which is essentially a 5300 with a 68k CPU), and it's intact electrically (structurally, it's a mess). I could probably spare the cable, if you want. c | |
| Posted by: Macdrone on 2013-01-24 07:40:21 If CC doesnt have a cable I may have one with a trackpad you can have. | |
| Posted by: uniserver on 2013-01-24 09:00:25 did you replace the caps in the PSU? for the IIfx sir? | |
| Posted by: mcdermd on 2013-01-24 09:24:02 No caps needed in the IIfx PSU | |
| Posted by: uniserver on 2013-01-24 09:37:27 IIfx working like it should? | |
| Posted by: mcdermd on 2013-01-24 09:50:27 It was a week and a half ago. Was running solid, like a champ for several days through several power cycles. I think the secret sauce was making sure that both batteries were truly 3.6v. One was 3.3v or so and made it spotty on booting. | |
| Posted by: mcdermd on 2013-01-28 14:53:00 I was given an Apple II over the weekend. It's a bit of a mutant and ugly as sin but the serial number and badge do indicate it started as a plain Apple II. It's a very late 1983 model (I honestly had no idea they manufactured plain IIs that late). It has a final revision logic board (RFI). Whoever owned it was a hobbiest, for sure. It has AppleSoft FP BASIC ROMs on the logic board (making it an Apple II Plus, essentially) and a full 64K RAM with the Language Card. The shift-key mod has been made. In the slots are a Videx VideoTerm 80-column card, a Grappler and a Disk II card. An external DIP-8 socket connects back to the internal game port socket on the logic board. The coup de grace is a big, 110V case fan bolted to the underside of the lid with vent holes drilled up top.  | |
| Posted by: Macdrone on 2013-01-28 17:11:48 I picked up a II plus , a II and a 540c with a Laserjet II printer for the cost of the trip. Pictures will come soon of what I get working. I found a radius rocket in a box so I am gonna have questions as I never k we anything about them. The guy said thirty dollars until I drove two hours then said I just wanted them to go to a good home. After showing him pictures of my apple stuff, which I have more pictures of than my kids at the moment on my phone, he said all yours and I was on my way. I looked in the II and all the capacitors look different in location to mine so I will have to see what's up there. | |
| Posted by: uniserver on 2013-01-28 17:25:09 wow macdrone do you have your own (My Latest ...) thread? that was a haul. | |
| Posted by: Cosmo on 2013-01-29 00:33:17 mcdermd, those holes look almost like an old analog-phone dialing plate! Very nice find. Almost an good idea to keep it as it is, an exsample of hot-rodded hobby machine from early 80's. If you want to go the restore-way, that lid you can find from ebay, sometimes they pop up without the logo plate for cheap. | |
| Posted by: Macdrone on 2013-01-29 15:35:07 Well the II has less capacitors to replace than my II. His was an 87 mine is an 89(year). I recapped the 8 caps and boom booted like a charm. I don't like my newer II, the hard drive was dead caps were bad (twice as many as the 87) and I still can't get it to boot. | |
