For what it's worth I have one of these Quaddoublers that came to me in a Centris 610 and it does work* in my Quadra 605 (basically same thing as LC 475). *Mine did not come with a fan so it seems to overheat and lock up the system pretty quick running at 50Mhz in the Q605, at only 40MHz in the...

I was looking at some docs I got that originally came with a Performa 475, they covered the "Macintosh Performa 400 Series" that existed in the later half of 1993 (410, 460, 466, 467, 475 and 476) and I noticed that the "Technical Information" booklet says the Performa 410 has a "MC68020"...

I've been trying to organize my Apple documentation/ephemera and have scanned the packing lists I have as part of that. Ideally I'd love to have all the original boxes and their contents that came with the items in my collection so I've picked things up when costs seem reasonable. It seems...

Impressive indeed! Curious, in the last pic, with a finned heatsink like that installed you just don't install the original heat spreader thing?

Jealous! Looks like it's in great shape! I've been wanting to add one of these to my collection.

😀 I think you need the 4MB VRAM upgrade for the PowerMacintosh G3 built-in video to do millions of colors at 1024x768

It's a cool monitor! I always wondered if the color scheme was considered for Blue and White G3... Some info about the stand not staying up/potential fix: https://68kmla.org/bb/threads/never-thought-id-see-the-day-studio-display-15-inch-flat-panel-rev-a.44864/

I love the Umax SuperMac c500 as well! I have two, a 180 and a 200, although the 180’s power supply is dead. 🙁 Is it possibly the most compact old world Mac …with two PCI slots? When I was in college in the late 90s we used a c500 as the NAT router for our college newspaper office to get all...

Something like this should work: https://www.ebay.com/itm/396921024428 https://www.ebay.com/itm/236458336933 I did some tests a while back and 100Mbps "Fast" Ethernet does make a difference. These tests were from/to my Raspberry Pi 4 "retro home server" running MacIPRpi (1Gbps Ethernet) with...

Not silly, I would think it should/could have worked, I can’t say for sure where/what the limiting factor is. System 7.1.x (which the PB 150 shipped with) is supposed to support up to 2GB partitions. I know I tried a 4GB industrial card that didn’t work. There is also the possibility that these...

I have larger CF (still industrial) cards in my PB 1400 (8 GB) and Quadra 630 (4GB), formatted with Drive Setup. The PowerBook 150 is an odd duck in its IDE implementation, natively it cannot use any version of “Drive Setup” instead requiring the use of its bespoke “Internal HD Format” utility...

Ditto. I have a Transcend Industrial 1GB Compact Flash card in my PowerBook 150. Definitely had problems with other “regular” cards, larger cards I tried first, either wouldn’t be seen by Internal HD Format tool, would fail format, or would fail when trying to install OS.

This is the stock MC88920? Replacing with MC88916 like this would be need go hit higher speeds? https://www.ebay.com/itm/135168460410 https://68kmla.org/bb/index.php?threads/upgrade-mc88920-to-mc88916-for-lc475-p475-q605-advanced-soldering.48616/

I've had the same experience. I've wondered if it has something to do with the tolerances of the RAM and/or VRAM I'm using.

Thanks. I bought a custom ROM SIMM years ago or my IIsi which I had forgotten the particulars of, it is is a GG Labs SIMM! Its really not doing much in my IIsi other than making is possible to boot from ROM for fun (or if the HD dies, needs troubleshooting...) so I think I will move it over to...
