I'm a bit late to the party, but I've had luck searching "Mac 128k keyboard" - long winded, but gets me there. "Mac 4p4c" however, got me back to this post lol. tinkerBOY calls his adapter "Mac 128k/512k/Plus" for PS2/USB keyboard -> Mac, but M0110 for M0110 to USB. And, I had great luck...

Drooling over this... kind of glad I don't live in Cali, nor have $16k! https://losangeles.craigslist.org/lac/ele/d/dania-early-apple-computers-lot/7681765088.html

First built prototype! :D

Great Strides being made with my 640CD! Got 8.1 installed, working on network drivers... then thinking I might look for an s-video extension cable to get my Logitech Mouseman plugged into the keyboard...

I watched a vid some time back about RAM speeds, though it was centered more around DDR, not older stuff. The guy was saying that any memory can be utilized as a slower speed, but sometimes the modules aren't as quality as they say. So, basically, in this case using faster modules ensure...

from what I can actually see (I'm unable to load the images to be larger, and the third is blank?) (annnnnd as I finished typing that, it loaded) It looks like you did not mess up. Of course, the comparison to the inside, wouldn't matter, since it too was RB'd... would had been useful info...

I've not heard of 3% peroxide bleaching much of anything other than my sister's hair back in the 80s. (and of course my friends' hair in the early 2000s) The true color should be visible on the inside portions of the mouse cover. Maybe it's not quite as white as you think, only compared to...

Like I said, not exactly a waste - I've got other retro projects to work on, and will have use for more RAM. Anyways, it came in today. I got it installed... annnnd 16MBs seen by the DOS card. I'm not sure if it's seeing the chips at 512K each, or what. I was hoping the different arrangement...

my thoughts, which, just random neurons firing in my thought bucket... An FPU won't help with the game, but maybe it'd relieve some of the background processes? Probably not, IDK. I replaced my LC040 with a full 040, with a speed bump(33 to 40mhz), but haven't modded the board yet, and...

got tired of looking for a pre-made battery solution for my 640CD... so, I spent way too much money, and got my wife involved in making 3D printed holders... >_> I might have gone a bit overboard LOL

I just watched Action Retro's "Turbo Mac" episode... I dislike cliffhangers. Especially on 2 cliffs! Though, he did say if it didn't work, we'd pretend nothing ever happened... :cool:

Everything I've read suggests 32MB is the absolute most the DOS card can handle. I don't know if that's actually true or not. Everything I read about my P640CD is 52MB max limit (4+32+16) and yet I've got it up to 196MBs! I have found 64MB modules that are single sided and with the chips...

So, I bought "64MB FPM MEMORY NON-PARITY 60NS SIMM 72-PIN 5V 16X32 SOJ OR TSOP" from ebay - works' well for the Mac. I tested it in the DOS card, and Windows only seen 16MBs - 1/4 of the total. I barely knew much about RAM back when these things were current, but could FPM w/ Parity...

I'm waiting for parts to build batteries for the Mac, so, am shopping for parts to build this contraption. I wish I could find the connectors Logitech used for the Mouseman 3 button mouse. The cord comes off the side of the connector, giving the back end a female ADB connector. Something I...

I got to thinking that might be the case, but seems there would be a pin on ADB dedicated to that then, which seemed like a waste... but I guess the kb power button was that important to the engineers (or at least management) That seriously simplifies this a LOT. I was going to start working...

I found a Google smart home / IP fan controller I bought for my loft fan a while back, never got around to taking the fan down to install it... i digress... I've been working on my Performa 630CD the last few weeks (just got it a month or so ago) - anyway... 1+1 and all, and I've come up with a...
