did you replace the big 220uf's and 470uf's?

 

[mcdermd]

Yep. And a 10uf, 16v and a 1000uf, 16v

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...

 

[mcdermd]

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.

 

[mcdermd]

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.

 

[uniserver]

:-D its solid now… great news man!

Yes mcdermd has an EXTREMELY high taste for quality machines no cracks or rigs for him.

His are the Real Deal, no silicone fillers

Picked up a few PowerBooks lately - a 190c, 5300cs and some parts to complete my 3400c.

 

[TheMacGuy]

Nice! I need to find a parts 5300 for that damn trackpad cable for the 5300cs.

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.

[Macdrone]

If CC doesnt have a cable I may have one with a trackpad you can have.

did you replace the caps in the PSU? for the IIfx sir?

 

[mcdermd]

No caps needed in the IIfx PSU

 

[uniserver]

IIfx working like it should?

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.

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.

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.

 

[uniserver]

wow macdrone do you have your own (My Latest ...) thread?

that was a haul.

 

[Cosmo]

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.

 

[Macdrone]

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.
