sparkdrummer Posted August 9, 2016 Share Posted August 9, 2016 I've had this computer for many, many years. Last time I used it (over 20 years ago) it worked fine. I decided to fire it up this morning and got the following screens. Couple of zeros on the screen - occurs every time power is cycled. Did the 2 apple keys CTRL reset and got this. Got this screen with a copy disk I have - No other disk will give this screen - most spin for a moment and then give a string of characters along the bottom. I tried seeing what rom version I have but apparently my n key isn't working so no PRINT. Anyway, I know nothing of these machines - Any Apple help?

david__schmidt Posted August 9, 2016 Share Posted August 9, 2016 Yep - you've got some bad RAM. That's what picture #2 is telling you. Time to open it up, pull out the RAM chips, solder in sockets, and replace the RAM. Quote Link to comment Share on other sites More sharing options...
JamesD Posted August 9, 2016 Share Posted August 9, 2016 This seems to be the most common problem people have posted here. Must be the type of RAM they used. Quote Link to comment Share on other sites More sharing options...
david__schmidt Posted August 9, 2016 Share Posted August 9, 2016 Exactly. Bummer they saved $0.27 per machine by soldering it in, too. Quote Link to comment Share on other sites More sharing options...
sparkdrummer Posted August 9, 2016 Author Share Posted August 9, 2016 I was kind of figuring that it was a memory issue - wanted to run it by experts though. I believe this is a first issue IIc - so it's probably got many ram chips, right? Anybody on this forum do IIc repairs? I don't know if my tired old eyes can do these repairs anymore. BTW - Thanks for the help! Quote Link to comment Share on other sites More sharing options...
Keatah Posted August 9, 2016 Share Posted August 9, 2016 Agree on the RAM being bad. And It's probably that Micron crap, //e's with Micron memory need an overhaul too. 1 Quote Link to comment Share on other sites More sharing options...
Osgeld Posted August 10, 2016 Share Posted August 10, 2016 (edited) Exactly. Bummer they saved $0.27 per machine by soldering it in, too.Oh the real economics of manufacturing You save about 27 cents per chip without sockets which at what 8 ram chips is about 2.16 dollars a machine Now sell what Wikipedia says was an average of 100,000 machines a year for four years... and your saving 864,000$ in 4 years ... in 1980's money (we all wish we could do that) Yea that's worth a few retro grumps fussing about having to buy. 9.99 desoldering iron ~ 30 years later Yes I do //c repairs usually the hold up is getting parts Edited August 10, 2016 by Osgeld Quote Link to comment Share on other sites More sharing options...
Keatah Posted August 10, 2016 Share Posted August 10, 2016 I understand, unofficially, the II series was engineered for a 25 year lifespan. Quote Link to comment Share on other sites More sharing options...

desiv Posted August 11, 2016 Share Posted August 11, 2016 (edited) Now sell what Wikipedia says was an average of 100,000 machines a year for four years... and your saving 864,000$ in 4 years ... in 1980's money (we all wish we could do that) Of course, the other side of the coin is you solder in the sockets for the chips and charge the end user $2.50 more per machine. Users don't balk at an extra $2.50 on a $1300 machine. Users/repair places are happy. Apple pockets about $34k... desiv Edited August 11, 2016 by desiv 1 Quote Link to comment Share on other sites More sharing options...
Osgeld Posted August 11, 2016 Share Posted August 11, 2016 (edited) //c is a non expandable almost sealed machine with a possible 25 year lifespan, why would anyone care back then also dont forget labor, you have to hand insert sockets they are almost impossible to machine place like chips Edited August 11, 2016 by Osgeld 1 Quote Link to comment Share on other sites More sharing options...
sparkdrummer Posted August 30, 2016 Author Share Posted August 30, 2016 After fumble farting around I got the bad memory chip replaced and the damn thing works. It looks like it is equipped with rom 0. Any tips on mods or whatever on this machine? Also, is there anyway to get programs from the Internet to this computer? Many thanks again to Osgeld for his offer of help! Quote Link to comment Share on other sites More sharing options...
Osgeld Posted August 30, 2016 Share Posted August 30, 2016 Yes you need a serial cable and then its super easy http://adtpro.sourceforge.net You can buy one, links on that site as well or I made one with a radio shack midi cable Quote Link to comment Share on other sites More sharing options...
Keatah Posted August 30, 2016 Share Posted August 30, 2016 (edited) https://www.bigmessowires.com/shop/product/floppy-emu-deluxe-bundle/ ..if you got some spare money laying around. Otherwise ADTpro is the premier old-school way of doing things. Edited August 30, 2016 by Keatah Quote Link to comment Share on other sites More sharing options...

sparkdrummer Posted September 1, 2016 Author Share Posted September 1, 2016 Well, I've tried running adtpro on my pc running Windows 98se and looks I don't have Java installed on it. I'm wondering if it will even work on this machine? I use it for all my ti-99/4a stuff with no problems. Yeah, I know, dead, dead, dead.

I'm wondering if it will even work on this machine? No idea. With Windows that old, you might try plain old ADT (not ADTPro). See ADT 2007_2: https://sourceforge.net/projects/adtpro/files/dos-adt/ADT%202007_2/ Quote Link to comment Share on other sites More sharing options...
sparkdrummer Posted September 2, 2016 Author Share Posted September 2, 2016 Huzzah! Success! I'm using adtw and it seems to work just fine on my IIC. Thanks to all that helped this old fart out. Quote Link to comment Share on other sites More sharing options...
