Did a test just now: Removed ALL memory cards (Apple Dealer 8MB and two 24MB Modules), booted it to my password prompt, and subsequently shook it immensely, expecting the cursor to seize up at some point. It didn't. But then I entered my PWD and was presented with this:
xx(
0000000F
00000069
That sounds more likely - those oscillator chips are pretty well sheltered too.
Upon one semi-successful bootup, I was greeted with a "Sorry, system error occurred" error with "illegal instruction" as the listed reason.
The plot thickens...
I've noticed that jostling or shaking my PB1400 will cause an intermittent system freeze (as in total freeze - even the cursor). My first suspect would be the soldering work on the new oscillator I just installed, but is there anything else that might cause these problems?
FYI: I have not...
Updates for 7/1/2010:
-Decided to group lists by series (looks nicer, more logical)
-Added the IIx
-Change user interface considerably to accommodate for long model names and pics:
I'm wondering whether the "list view" of classic macs should be organized by group (i.e. II series, Centris series, Quadra series...) or simply chronologically (which makes for a rather mixed-up looking list)
Poll, anyone?
AFAIK the batteries used in Pre-G3 powerbooks were pretty "dumb." That is, the only way they detected charge is via measuring the output voltage - the battery itself contains no special hardware. On 1400 series batts, the ID board is only a transistor and some wiring - The duo batt is probably...
I have successfully rebuilt a 1400 battery! Granted, there are some practicality issues with my design: the top cover of the batt (which is only cosmetic - it's the bottom cover that has the latch and faceplate) can't fit. However, it works great: It powers the 1400 just fine - even the battery...
Actually, MacBench 5 reports that I am indeed running at 199.99 MHz. Apple System Profiler seems to have lied.
So, who wants to benchmark an original PowerBook 1400c/166 against me?
I just installed a 40 MHz oscillator in my PB1400, replacing the original 33.333 MHz one, as seen here: http://home.comcast.net/~gionpeters/hhhh/pb1400.htm
The oscillator, while difficult to solder in (solder points are fragile), seems to be working properly. However, I don't really observe any...
Ok, so here's the first update of what's done so far on MacRefLib:
Basic GUI Setup
"About" Page
And models done:
128k
512k/ke
Plus
XL
SE
SE/30
II
To do list:
Pics (licensing needed)
Search function
All 9 categories of devices.
The question is: I know I need a system enabler (number 065), which I have installed by placing it into the System folder. Problem is, it still complains of the system needing to be "updated" at boot time.
What do I do?
I'm currently developing a MacTracker-esque Hypercard application called MacRefLib (thread here: http://68kmla.org/forums/viewtopic.php?f=29&t=16375). Some (but not much!) development has already occurred on a Performa 6400 and a PB 1400c. However, I realize that's there's really nothing...
Caps are an unlikely problem with computers that new. Usually the "black box" (as I can them) PRAM batteries that the mid-90's Performas use don't leak. However, by now it's most certainly dead.
If you want to make a quick PRAM batt, just cut off the wire + connector from the PRAM batt and then...
