Received mine today, and I'm am very disappointed about the installation instructions. I'm experienced with the soldering iron, but that's not enough, because it's an IQ test to understand how to put this together.

Problem: The voltage regulator is too thick so it makes the upper 060 board even more lifted up, thus all the hundreds of pass-through pins won't connect firmly to the lower ones!

What am I doing wrong? There are *NO* pictures of the assembled lower 040 board, could someone please upload some angled pictures of their finished adapter?

If your having any problems or need any help/tips why not PM me.

It's a common problem with all of these kits. If you just build the two boards with the parts supplied by Pghulme, they won't fit because (as you have pointed out) the voltage regulator is too high. This is a design flaw, and in my opinion the kit is not "complete" because you will need more parts to have it operational.

You have the following options:
- Mount the voltage regulator on the underside of the PCB. (ugly and it will interfere with capacitors on the A3640 so not very good)
- Build a "riser socket" of more pin strips between the two PCBs. This has the added benefit that you can leave out the blank pins of the upper board, so they cannot make contact and short themselves.

I find currently the best solution (time wise) is to use 1 040 socket for the bottom board, 1 060 socket for the upper board (and clip the necessary PINs AFTER soldering according to the design), and finally build a riser board of PIN strips. Of course 060 sockets are hard to find and pricey, but you save lots of time, besides building the top socket out of pin strips is NOT ideal because the pin scokets will be too tight for the 060 CPU pins.

If you look at the pictures and instructions in the A1k thread you can see that most build the bottom most layer using loose pins (taken from pin-strips or 040-sockets): http://www.a1k.org/forum/showpost.php?p=644306&postcount=188

That seems like the best solution to me, albeit a quite labor intensive one. Just got to source some extra pin-strips or a 040-socket.

I used some thick jumper leads to make the volt reg. go outside of the board. I made them as short as possible to prevent them from picking up any noise/static. Anyways, kit install is done, and I've made sure there's good contact between the layers. Even did a continuity test from bottom of accelerator to top of adapter (without CPU install).

Just to test (even though I know I need the 060 patch in the kickstart) I get a black screen and nothing more. I can't even get to the early startup menu, nor do I see a kickstart screen. Is this normal behavior before you modify the kickstart ROM image?

EDIT: Also, it does support the late-mask 71E41J MC68060RC50 CPU, right?

Is normal behaviour until patch rom as kickstart doesn't expect/support FPU

I am planning to order three of these kits for my accelerators. I am a little concerned about sourcing the actual processor though. I have read some of the chips on eBay are fakes. Can anyone point me to a reliable reasonable source? PM is fine, I'm in the US.

 

[Pghulme]

Some are maybe mis-masked so say one version but actually a different one, but this is rare I guess. For best/easier results just use one without FPU/mmu

So is eBay at about 75USD about right, or should I keep looking?

 

[Pghulme]

id keep looking
ive bought for 25gbp which is about 50-55 usd

[Rakeim132]

I'm a bit disappointed... I've ordered one of these kit but it seems we have to build it not as per the instruction?
