Carlo, since my HyperDrive 20 Mac is a Macintosh 512k with the "512k" label on back and with a stock Macintosh 512k board that has never been swapped out or upgraded, I am happy to…

I first wanted to hear from PB100 owners … Click to expand... Err what I posted about was expressly about a PB100, unless I'm wrong! JB Click to expand... Sure! I just …

Carlo (Mr.T), after reading your post again I see that you are expressing disappointment over not having a stock 128k. What I can say is that 128k logic boards are often sold on E…

Is there a control panel installed you can check to see if the accelerator is running? Much easier with newer Daystar upgrades on IIci's that replace the happy mac with one that s…

Thanks! Got the RadiusWare disk installer; everything installed fine, but I don't get the opening screen on startup.

For the records: A 9.2.2 CD bundled with a later G4 worked quite well. It´s still verry strange to me, but the bought 9.1 refuses to boot, but a 9.2.2 works (even if it was made f…

Welcome aboard! You'll find lots of kindrid spirits here.

Welcome!

Thanks for the answer! First though I'd reseat the RAM and rebuild everything. Then I'd do the old "clean the board with metho" or put in in a dishwasher, leave to dry for …

TBH I think they both were integral to the creation of Apple. Basically: Woz: did all the hacking work, and awesome stuff. But could not do a presentation for his life (No Offens…

Welcome aboard, comrade! I'm sure you'll fit in fine, we've already got a few Steve-o-philes here in the 68kMLA! : I'm a "woz" kinda guy myself, but we've got room for all sor…

Hello, and welcome to the forums!! I am sure you will find a wealth of information about classic and old macs, since that's what we do here. I hope you enjoy your stay, and pleas…

Beck-Tech's modified ROM was exactly the same as the original, except that in about a dozen places, Andy had hard-coded the screen address for 512KB of RAM, and those needed to be …

Thanks for creating and hosting this forum. I bought my first mac, a Mac Plus, in 1986. So I guess -- probably like so many here -- I was a "Mac" guy way back when Mac was cool, an…

JDW, the pictures referred to show the decoder. Before there were little decoder boards made, people piggybacked an additional 7AS153 atop the one at F3 as in this photo: http://h…

(Are you speaking of the 7 holes shown in my photos between RP1 and C34? Click to expand... That is exactly right. There are many pictures on the forum of these mini-mux boards …

Here are my 128k logic board photos, which show top and bottom and many angles. Click on the individual photos, then click on the little "All Sizes" button above the photo to see …

I have a couple of early 128K boards; both are marked 820-0086-C in the top copper layer, and printed with a © 1983 date. Later 128K/512K boards do not need the little decoder boar…

Hi all, as this is my first posting i like to introduce myself a bit. I'm Carlo from Germany and I'm an longtime Apple user. I started with an Apple //c in 1990 and now I'm using…

Hmmm. The discussion about H2O2 makes me wonder what effect a solution of KNO3 would have... For that matter, given that the Oxi-whatever produces H2O2 can you just dispense with…

JDW: Nice work! I saw your pictures and your mac/parts/pieces look fantastic! I've been away from these forums for the summer and was glad to return and see you had given it a t…

I pulled the on board cache card from the mother board when I installed the G3 years ago. This was recommended in the Sonnet installation instructions. The 500Mhz G3 processor wo…

Is the motherboard onboard cache disabled or enabled? When I had an 8500 and a NewerTech card if I ran the onboard cache alongside the CPU cache I would have some of the same issu…
