actually, it's command-option, and tests are off already. Hmmm.... High Speed Compact Flash time!

I've noticed, as of late, that my PB 1400 spends quite some time on the Happy Mac and Welcome to Mac OS screens (before the extensions parade). Is this more related to extensions or just a slow system (namely the HD - still haven't figured out what the IBM's drive's RPM is, bt it's probably low)...

Damn! Those would have fit my old IIP+! Yet another reason for which I regret throwing it out.

Better return it sooner than later and then get the HP model.

Just got email from the seller. I asked about exchanging this module for one that WILL work in an LC, mentioning that it has to be single banked. He replied by in forming me that the one I received IS single-banked. :?:

Give it 10.2+ and then use it as an Appletalk to SMB/Windows networking bridge, as well as a file server for Mac software for your AppleTalk network.

Looks like it's time to ship it back. I'll ask the guy if he has modules that WILL work in a Performa 6300CD/LC 575. Speaking of that, what specific type of mem is needed? Single banked, low density, etc?

The other side is just memory chips.

That's exactly why I looked for something with free shipping.

Look, I didn't know at the time. I know NOW that it's an actual 64MB module. If I could change the post title I would. In fact, I will. Note to Mods: please change this topic's title to "LC 575 Memory Problem." And I did do my research prior to buying. I thought this would have worked fine...

There appear to be three capacitors along the contact edge, but besides that nothing interesting. See pic: Uploaded with ImageShack.us

According to this reference data sheet: http://www.datasheetcatalog.com/datasheets_pdf/H/Y/B/3/HYB3164400AJ-60.shtml Each chip is 64 Megabits, or 8MB. And there are 8 chips total, so 8*8=64MB Well then it is a 64MB module! But why will only 16MB be detected?

For those interested, the RAM chip's model num is: SIEMENS HYB3165400AT-60 9820

I contacted the seller and received this message in reply: " You bought the wrong memory for your Apple Macintosh computers. Both of them (LC 575 and a Performa 6300CD) can take a max of 32MB simm made of two memory banks. These 64MB simms we sold are 64MB made of a single memory bank. Each of...

I just recently bought a 64MB memory module to max out my LC 575. Bought from this page here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160527757777&ssPageName=STRK:MEWNX:IT It came in the mail today. Packaged fine, took it out, put it in the LC, and booted it up. About This...

I reason I ask is because I happen to have a spare processor card for the 1400, and would be willing to "donate" it for experiments, on the condition that I have it returned in the case of actually creating a G3 upgrade card.

Well I can already see one problem. The CPU die is attached via Ball Grid Array, which isn't easy to reproduce using hobbyist soldering equipment.

I just read online that the PPC 740 (aka G3) is pin-compatible with the 603ev. Although i'm sure there more to it than just this, but couldn't a 603 be desoldered from a PB1400 processor card and replace with a 740 to make a Sonnet Crescendo upgrade card?

No interest in OSX - i'm all about Classic Mac OS.

The IIfx wasn't positioned as a home computer - it was a high-performance workstation. The people who needed such power at the time could well enough afford it.
