Something I have been working on recently: It's a near 1:1 reproduction with some minor rerouting where this made sense. Boards are on order, should be here in a couple of weeks Not much more to say (other than thanks to @Kai Robinson for providing the donor board I used) you have all seen...

Me and @jajan547 are currently working on creating a replica of the Apple Techstep This will be a functional and (mostly) electrical clone of the original but will not be a exact 1:1 copy as the design will be optimised where changes can be made to make the board easier or cheaper to assemble...

Normally the LCIII is limited to 36MB of RAM - 4MB onboard and one 32MB SIMM The simms are limited to 32MB as there are only 11 address lines hooked up to the RAM SIMM socked so larger sticks won't work (The will typically show up as 16 or 32MB) However while creating a pin listing for the...

I have a troublesome Apple Tanzania board out of a StarMax Clone sitting on my desk at the moment When powered on it boots to a grey screen with the mouse pointer on but never gets any further, the board dose not chime and never attempts to read form the floppy drive The board has suffered...

It's time for another one! The LC II went much quicker than expected so it's time to start on a board I have been looking at for a while - the IIcx The IIcx in question was actually purchased as a repair project until I noticed the board had layer marks, and to my surprise it was a 4 layer...

With the (hopefully) final revision of the LC 1 board and the second revision of the LC III both with JLCPCB for manufacture it;s time to turn my attention to the LCII. This was initially going to be the second board LC board I worked on before that pesky LCIII board distracted me... The boards...

Time for another board! I was initially intending to work on the LC II board next, however about a week ago I picked up a LC III board and started having a closer look at it, I initially expected this to be a 6 layer board and require redrawing form the schematic however the closer I looked the...

With my Plus PCB's something along quite nicely (And by that I mean I'm refreshing JLCPCB's order page every 4 minutes to see how production is getting on) I decided to look at what to work on next (Something that actually needs reproducing!) and settled on the LC series, battery damage is...

Like many of us I have been following Kai and Bolle's Progress in reproducing various Macintosh PCB's I thought it might be fun to have a go myself! I ended up settling on the Macintosh Plus (Even though there is no real need for Plus reproductions) since it is a fairly simple PCB (2 signal...

Simple question, Where activity LED's in older macs on blinking off for activity or off blinking on (Like modern pc's)? I need to sort out the activity LED circuit on my SCA to SCSI adapters (Which techknight pointed out to me was incorrect several years ago but I never got around to fixing...)...

Picked picked up fairly nice looking PB100 on eBay a few days ago, Seller was fairly local to me so shipping was fairly quick Got it today and luckily it survived shipping OK (The packaging was not the best I have ever seen, but was far from the worst!) I can't test it yet as the power adapter...

A little while ago I brought a ago I brought a Performa 400 on eBay with battery damage, today came the day to try and get it going again First ting was to clean the battery residue off the board, this was done with vinegar and a lot of scraping, then washing in water to remove the vinegar...

I'm working on a battery damaged LCII (well, actually a Performa 400 but it's the same mac, the logicboard is even marked "LCII" :) ) As far as getting the board working it is all going well, the board cleaned up really nicely with some white vinegar and  I ever managed to save the rom chips...

Dose anyone have the pinout for the PowerBook 1x0 series FDD connector? I am wondering if it could be adapted to work with desktop mac's (I have case mod project I need a FDD for and recently found a couple of powerbook FDD drives which would work better than the desktop drives as they are slimmer)

So I'm trying to figure out what's going on with my IIx, When turned on it it chimes and immediately gives chimes of death. According to apple's troubleshooting guide this is a ram issue What I have done so far is: Recapped the board Try with known good ram (Both in all 8 slots and only in...

So over the the last couple of years despite not doing much work on my vintage computers I have been keeping a eye on the scrap pile at work in case anything interesting turned up on it, a consequence of this is that my iBook collection seems to have grown form 2 laptop's to 6 :) Most of the...

It's been a long time coming, But I finally gave this a stab today I started by removing the old CPU from the card (anyone who dose BGA rework professionally might want to look away, my setup isn't exactly pretty....) A overview of the setup, I'm using a griddle as a preheater and a attan...

I'm looking for a little guidance here, I have brought a USB to RS422 serial adapter and have wired up a according to these instructions: http://www.emaculation.com/doku.php/imagewriter_serial_cable_printing(I'm using a different adapter, but have wired it up the same and can't see why it should...

Finally i have my portable working! Just got it's logicboard back from it's 8,000 mile round trip to techknight (who i must thank for all the work he put in, removing all 32 ram chips not once, but twice!) I put it all back together (amazingly i didn't loose any parts while it was sitting...
