    PB1400 Random Freezes

    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

    No, I replaced it with a CF card a long time ago....

    PB1400 Random Freezes

    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...

    PB1400 Random Freezes

    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...

    Developing my MacRefLib project on my LC 575?

    Update 7/3/11 -Nothing to speak of - spent the day with a friend launching fireworks. Will do work tomorrow.

    Installing System 7 Pro (7.1.1) onto a LC 575

    Figured it out, needed a slightly newer version of SE-065 that actually supported the 575.

    MacBench 4

    Oh, AppleDouble encoding. How do I "rejoin" the resource forks in 8.6?

    MacBench 4

    Does anyone know where I can find MacBench 4 online, or possibly even send it to me? I just want to benchmark my overclocked 1400.

    Developing my MacRefLib project on my LC 575?

    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:

    Developing my MacRefLib project on my LC 575?

    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?

    68k PowerBook battery calibration issues

    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...

    Anyone here rebuilding PB 1400 batteries 'for hire?'

    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...

    PB 1400 40MHz Overclock

    Well, my Farallon EtherMac card still let me talk to my W2000 server. My Orinoco WiFi card also seems to work.

    PB 1400 40MHz Overclock

    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?

    PB 1400 40MHz Overclock

    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...

    MicroMac Power WorkStation - Did anyone ever buy one?

    Expensive? If I paid $1200 for my LC II, and a year or two later wanted to upgrade it to match, say, a Q700, I'd certainly pay $199!!!

    Developing my MacRefLib project on my LC 575?

    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.

    Installing System 7 Pro (7.1.1) onto a LC 575

    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?

    Developing my MacRefLib project on my LC 575?

    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...

    Performa 6200CD found - any maintenance?

    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...
