Any suggestions to resolve this known Apple IIci power-up issue?

Greetings, especially directed at all with "grey-haired" Apple knowledge....


In the 1980s, I wrote a compiler for a subset of Pascal, using Apple Pascal on my beloved old Apple II+ with a whopping 48k RAM.

Believe me, it taught judicious use of memory and very modular and typehecked code.


Later, after completing my BSCS using Borland Turbo Pascal on a Leading Edge Model D 8088 system, I bought an associate's Apple IIci, and used it until I bought the "Beige" G3 PowerMac waiting to replace MacOSv9.x with MacOSv10.


I kept the IIci and before moving to California from Oregon, I kept it tucked away. About six months ago I decided to revive the 68030/MacOS7.x for access to old Passport music composition software.


After setting up the monitor, system, and external (huge in size) hard drive, I was able to startup to my system full of software and programming memories. It waited its turn in my list of projects, and at the beginning of 2013 I tried the startup again.

I watched as the monitor telecast the system's attempts to arise, but midway to seeing much on the screen, the process would cease.

The same each time, as if the plug was being attached and then pulled.


Then, amidst attempts where I violated my QA code to try one thing at a time, I stumbled upon some configuration wherein the monitor was getting "charged up" like a capacitor, perhaps in tthe previous configuration, the monitor appeared to be "kickstarting" the IIci, like one of those hospital scenes with "the paddles".


Eventually that didn't work, especially since I dropped the project until mid-2013. No "leap" past the short-lived and repeating flashes on the monitor screen.

I took it to a Mac shop in walnut Creek since the local Apple Store wouldn't work on it. They opened it up and replaced the old 9v battery with the recommended replacement. Still, no change.


So, as old II+ systems had many problems with power supplies, I may have one, or I may not have repeated the correct sequence nor been in the correct configuration.


Your familiarity with the issue, and any recommendations short and long term, are much appreciated. I love this "the little train that could" system and would love to get it up again. I have contact with the local Mt Diablo MUG and will be searching their ranks for ways to narrow down the problem so that both its assurance and work-around are reproducible, and thus, make a deeper query possible.


Any "aha!" and "oh yeah!" expositions will be welcomed as points of test and study.

Thanks.


Best wishes and a great 2014 to you all.

Hi,


If there is a change during storage, one could suspect a problem with the logic board battery or electrolytic capacitors. Since you had replaced the logic board battery (I guess that you mean a 3.6 V lithium battery!) in the Macintosh IIci, it might not be a bad idea to carefully inspect circuit boards (using a magnifying glass). Generally speaking, electrolytic capacitors appear either as rectangular surface mount devices (SMD) or round cans with leads. Look for leaking, bulging or cracked capacitors. At the same time, look for other damaged or discoloured components.


A power supply issue cannot be ruled out. Could you check the output voltage levels with a multimeter? At the same time, you may want to verify the logic board battery voltage.

Can anything else (icons or messages) be seen on screen? Do you have access to another monitor that could be tried instead?


Can all the normal startup sounds (including the hard drive working) be heard?

BTW, would it be correct to assume that you have tested a startup without any external devices connected to the SCSI port?


Also, what happens if you try to boot the computer from a floppy (such as an appropriate Disk Tools disk)?


Resetting the PRAM is probably not going to make any difference here, but it can always be tried.

Thanks Jan for your kind-to-reply and bonus focus. upon my IIci dilemma.


I went out to define a test-and-implement scenario, with my 3.5" Test Tools Disk in hand, and,... oops.

Eaten temporarily during a failing startup which no longer puts a flash onto the screen at all.

That does tell me the available power is now less. I will try sebveral other setups with power to the monitor not coming so briefkly beforehand, from the back side of the Mac.

I'll get my handiest of tools, the paperclip, on that Disk Recovery recovery asap.


The current state of the system, does not make it to the held-down-key read which directs startup to the disk drive.

The "turnoff", so very much quicker now than last tested, suggess further reduction of any startup "juice".

The system has an external CD drive, however, I expect the internal to get to a certain point before committing to it or to be redirected, and I do not think it gets that far.

It used to, geetting a flash on the screen.


An associate at the local Mt Diablo MUG has some ideas to convey tomorrow. The group is veteran robust so I am certain that eliminating possibilitites and finding some way to pull data or induce startup (a sort of virtual jumper cable) will allow a startp source redirection..

Have you heard of power source problem tests or replacement/rebuild sources, and what may typically have gfone awry?


Any switches or a different set of startup keys to send the software startup in a dfferent vector?

How'bout a hard switch so the current power ssource failure can be averted?


So...I am also thinking of re-charging and re-changing the internal battery, but not having been the one who put the new one just a year ago, I will need to be enlightened and/or to research its locale which I missed last time. I could not find an=y service manuals showing it. Sites with online manuals at that depth.


Also, can you suggest tests besides startup, which would test the power source within?

You may well be correct in that the battery issue coincided rather than precluded the current symptom.

How often the Apple II-family power source died. Any reputable sources for original replacements and/or current-tech fill-ins?

It is difficult to find many who work on boards and their components today.

I was lucky when living in Portland OR to find such a shop just south in Tigard.


Perhaps I will give them a call.... They saw this particular box approximately 8-9 yewars ago.


I really am intrigued with the ability to start the internal code "inside the box" from or on another system "outside" of the box. Pulling data off "in the dark" of guessing where it all is means knowing its whereaabouts, as well as knowing if that has any methods mappable to this very accessible inner system.

Just as we can start a box from different "memories" of its startup criteria (OS),

I would hope we can access that internal drive's memory froma startup off its system.

Not sure how.


The similarity and crossover of my IIci's OS possibilities and my G3 PowerMac (the beige one that had install drive sizes killing Mac OS X 10.1 installs (and perhaps USB issues) haunts that system as my "also"-bringback project.


The MC3501 I ordered and recently sent back was missing keys and its internal connector wires were bent. The Zip drive for backing out data beforehand was not being recognized by my internal Orangelink Internal Firewaire-USB Card... so, I may now approach thes two system solutions as maybe residing within each others set of hardware, software, and first aid acts. After all, their OS relases are not as distinct as the actual switch from 680x0-to-Gx PPC chipsets. Amazon shows suppliers but many are short of truthful descriptions about

the set of hardware, software, pin count/positioning, documentation, condition, driver/install disk depenndencies, etc. I have disks going back through SSI games. I know this may take time but I am trying to recover my sold life timemback from all those 60-hr weeks at Tek, Intel, etc. It's worth it and fun. A will... a way, eh?


thanks again Jan and sorry for my late-night ramble w/its off-topics, but we are people, after all, not binary signals. ;-)


best wishes,chris


post-note:

My recollection is that near-the-end 7.x system release were co-marketed as the "MacOS 7.x" OS, and I would imagine, partly because they overlapped from 680x0 to Gx RISC runnable. That said, maybe I can find more tools for recovery iin the tools availed for that crossover period?

Of course, it could have scared off developers, unless the compile twaeks were minimal/minimized.


I just need, on both systems, to rescue data and all my pref/user setting files. I have or camn reacquire almost all applications.


So, the IIci system's startup requireneeds may require a hardwaire redirection /replacement (although I'd prefer spending coin on devices usable "beyond" just the IIci., and ... the PowerMac needs are software.


The latter has five (5) System Folders with three appeasring to be "blessed" I finally moved in an Extensions Manager from another rendition which did not say that a 9.2.2 release came before an 8.5 one, and thus, allowed it to operate. Sadly, turning off all extensions and control panels made no difference and the second icon appearance during startup locks up as usual with the empty dialog box overwriting the OS9.0 headeing.


Strange that the past lost to all the school and jobs back then is still captive and out of reach.

Who knows... some flight of imagination can easily amuse me a shared solution?


That would be quite nice.


So, thanks again Jan. Comment on which ever (or both) you wish. These older Macs, like older Porsches, are so much more connectable as people-people affairs than today, and I am so very smiling at being able to find sharing that has transcended what SMB-NFS-AFP has not. ;-)


That was a reference to athird "situation"" of communicating amongst an XP, Ubuntu, two 10.6.8s, the IIci, the PowerMac, and peripherals made by Canon, Epson, HP, Lexmark, Talk about a noisy silence? More fun.


Sorry if this was 'all over the place", but I shift sub-projects to maintain sanity.... and am uncertain as to whether it has worked at all.


best,

chris.

Hi Chris,


>Have you heard of power source problem tests or replacement/rebuild sources, and what may typically have gfone awry?


With many older computers (both Macs and PCs), it is not unusual to encounter power supply problems. This may be related to leaking/bulging electrolytic capacitors, or faulty semiconductors. You could try to search the Internet for something like 'bad capacitors' for further information. One would (normally) replace a faulty power supply, not have it repaired.


>Also, can you suggest tests besides startup, which would test the power source within?


With a digital multimeter, it should not be too difficult to measure the DC output voltage levels from the power supply. You may find details via a web search for 'power supply Mac IIci'.


>Any switches or a different set of startup keys to send the software startup in a dfferent vector?


Apart from attempting to reset the PRAM (see my previous message), there is not that much to try.


>I am also thinking of re-charging and re-changing the internal battery


The 3.6 V lithium logic board battery is not rechargeable. When necessary, it has to be replaced.


>I will need to be enlightened and/or to research its locale which I missed last time.


The battery is placed in a plastic cage. A web search for 'Mac IIci logic board battery' should provide you with more facts.


>The current state of the system, does not make it to the held-down-key read which directs startup to the disk drive.


When there is a floppy with a valid system folder in the floppy drive, the computer will start from this disk (not from the internal hard drive).


>The system has an external CD drive


It is wise to disconnect all external SCSI devices before carrying out any tests.

Thanks Jan. I'm determined to find another Apple II+ to add to a LAN with my other systems: IIci (M68k) running System7.3.5; beige PowerMac (MG3) running MacOS9.2.2; Mac Mini (IDC) running MacOSX10.6.8; iMac (IDC) running MacOSX10.6.8; iMac (MG5) running MacOSX10.6.8; Pavillon running Ubuntu/Debian; eMachines running XP.SP3.


It's quite the drive/app/user/peripheral sharing challenge! Nonetheless, quite fun....


I regain access to approximately $10k in useful/usable software... rather than spending for duplicates and for questionable "upgrades" that are merely fixing bugs which should be free fixes as far as my 30 years as a SW engineer are concerned.


So, thanks again.


I'll deploy all suggestions and will, "by hook or by crook" [cf., "The Prisoner"] resuscitate the systems. None shall not be left behind, esp. when Stalinist China is making the replacements... for Apple and for the Constitution as a result.


They're such nice folks to handle the improvement of "planned obsolescence", so that Apple's elite keep raking it in, at loyal Apple users' expense. ;-)


best,

chris
