a number of the OS 9 bootable MDDs have 167mhz bus speeds and DDR RAM and ATA 100. Having a faster processor on a slow bus is limiting. Click to expand... None of the Prozesso…

why you want an os 9 only machine is beyond me but the last os 9 capabel machien apple offerd was the 2003 reintroduction of the 1,25 dual G4 MDD

I doubt very much that a single thin piece of metal can absorb and dissipate heat in any meaningful way to actually maintain or reduce temperatures. Larry Pina's Macintosh Repair &…

Yes. The 54xx/55xx boards and their 6xxxx counterparts are interchangeable.

OK, I'll downgrade My IIcis fDD rarely formats my FD's correctly. It just says "Initialization failed" or "Initialaziton Failed because the disk is defective." HopeFully System 6…

sys7 wont work. it has a differant format window you might have to try a bunch of disks fefore it works.

6.0.8 works. i'll check sys 7

i forget if it will work with system 6 or not. i'll check.

Would 7.5.1 work or not. Probably not. I'll have to downgrade my IIci to 6.0.4 that came with it.

My 5500/250's motherboard seems to be acting up. Thanks! -JRL

iirc, for a 400k floppy (not as reliable as with an 800k.400k one) take a 1.4 meg floppy and tape over the hole without the slidey thing in it. stick it into an old mac (iirc, sy…

OK I got it and unboxed it. Works great. It has a REALLY nice CRT. Bright and everything. The light in the FDD is on and is red ooohh. No boot floppy for it yet. It is in very …

So it's either that the two read/write heads in the Plus's drive are misaligned, and so only the lower one works when it's alone (hence the 400ks being read but not the 800ks)...or…

Even with the Mac 128K Apple was installing heat sinks to help pull heat away from the delicate electronics and radiate it into the case where convective air would then exhaust it.…

I've never heard that any particular, fairly modern, OS can't utilize dual/multiple processors. NEVER believe (without checking multiple reliable sources) what you've "read at diff…

Sonnet lists an upgrade for the Mirrored Drive Door. Click to expand... Yes, but the 2nd processor can´t be used by OS 9. That´s what I read at different places. It will fit, i…

An "eleventy" conquest happened to me at least once: when I volunteered at a recycling drive and was able to literally intercept a very nice SE before it got put into the "truck of…

It booted from and ran the 400k system disks that shipped with my Macintosh 512k!!! Problem is: it spat out the 800k disks that I prepared for it on one of my SEs. Click to exp…

I think 10 NiMh AAA batteries (the small ones) might work, but have not tried it — this project is still to come, some dark winter's night. Ten regular AA "button" batteries will n…

QS2002 can use HDDs larger than 128GB on the internal PATA buses.. but that is about it as far as I know and it does not do you much good if you want SATA or SCSI RAID.
