OVERVIEW A limited number of Macintosh II CPUs were manufactured with an HMMU-unique socket that does not allow the CPU to function properly if a PMMU upgrade is installed.  Custom…

I said that up top. Recalled because of a socket issue. The four chips to the lower right, see those? The black upper right one comes in versions that have different pin layouts un…

just an update havent had too much time to look into the power supply further.  But one thing, i did stumble across a site called atxg4.  He has adapters to use atx ps in g4's. He …

to uniserver, the board in the top pic is the one i am currently working on, its the working one.  On the other mac II i have the board pictured on the bottom.  One thing though, i…

If you can get both yes. I have a 2GB CF in a PCMCIA Adapter which I copied the System 7.6.1 on my 5300ce as a back up drive, and tried it on my 1400/133 & 166. They both …

Ya, but I am just making a list of models. Im not interested in motherboard variations, etc.

unity said: I could be wrong. I just have never seen a model like M0001EP or M0001AP, etc. I could put them into the list proper, but that would add a few lines for sure!  …

Should I purchase a floppy module as well as the CD module?

YAY!

I have a 1400c/166 running 7.6.1. No problem.

So, I am thinking of getting a PowerBook 1400cs/166 off eBay to run Mac OS 7.5/7.6 (I'll probably use 7.6 since it's better on PPC) really fast. But, everymac.com says that the 16…

Given the pin out for the Powerbook 5xx series charger, could one be powered by an AC adapter that only has two wires, one live and one ground? My thinking is I could tie the groun…

There are 3 main revisions of the Lisa Hardware, the original with the twiggy drives (Lisa 1), the updated version with one Sony drive (Lisa 2) that is otherwise the same as a Lisa…

I need to find photos, if I have any, of my sold Mac XL. I am starting to think it had that spare cable too now. But its been so long.

The sticker on the case says A6S0300P  Thats why I call it a Macintosh XL. See: http://en.wikipedia.org/wiki/Compact_Macintosh I find it complicated these names.....

The 220V-240V, 50Hz, .7A PS would be correct for Lisa's in Europe, it's nothing special.  Later Lisa 2/10 (XL) units with the widget drive used a 1.8A PS that was internally 120V-6…

As I told here before my other Lisa has also the "strange unused power connector". See below. It say on the casing also that it is a A6S0300P There is also the PSU I can't find…

Thanks for all the suggestions! I think I'm going to have a look at it this friday, I'll keep you updated with my findings!

The two 26 pin ribbon cables are for the upper and lower twiggy drives, these cables have both data and power in them.  The other 3 wire plug is for nothing, Apple never used this …

And this is why I love this group. Great info here!

The Apple part number may be different on the label, I don't know if it is or what is should be to indicate a 2/10. The normal differences that I look for to indicate a Lisa 2/10 …

Thank you for this update. So this was a formally Lisa! Nice to know! Could you tell me two things: -Is it normal to find a sticker on such a Lisa that indicates that it is a Mac…

1st of all you don't have a Macintosh XL (AKA a Lisa2/10), you have an original Lisa ( Lisa 1 or converted Lisa 2).  The two 26 pin ribbon cables are for the upper and lower twiggy…

Too bad you "HAD" that 5300, Bibilit. Not only is there problems with the power connection on the 190/5300 but sometimes when the battery leaks, the PSU Area (under the trackpad) i…

You're missing the Widget's power harness. That three pin power cable is for a Twiggy floppy drive and indicates that your Lisa did not start out originally as a Lisa 2/10 or an XL…
