Replay cased and pretending to be an Amiga A1200

Here is a picture of the board in a mini-itx box. It’s the smallest case I could find and the Replay board takes up about 1/3rd. I need to make a small adapter board for the ATX PSU then the board can be powered by the rear 4 pin molex. The hardware is fully...

First board shipped

The first board was shipped out to another developer today! When we have a working initial firmware I will start shipping the rest of the boards. Please don’t email me yet!

Replay power fixed

The replacement regulators work well and solve the power off problem. I’ve been testing the luma trap response with burst test patterns generated in the FPGA. The hardware is working well, but I am starting to think the trap may not be worth it for...

Power supply issues with Replay

A quick update, I apologize for the delay. I’ve been really busy testing the boards. No real problems as yet. I’m waiting for a different LDO as the one I am using does not shut down when the input power is turned off, and the resulting reverse leakage...

Replay RevB finally assembled

A few more pictures now I’ve assembled the through hole components. You can see one board does not have the components on the backside, this is the version without the composite/SVHS output. The board you can see from the top has the codec and the extra output...

Assembly started

Good news, the missing connector which was on 3 month lead time has finally arrived! The components are packed and shipped off to the production people for the prototype assembly. The paste mask needed for assembly has also arrived, so we are good to go. Hopefully I...

Replay update

I’ll just sneak in a little update while it is still August 🙂 Well, late July didn’t happen never mind early July. All of Sweden seems to shut down during the summer, and getting a production slot has proved difficult. However, we are going ahead now. If...

Festival time….

No news at the moment, I am still waiting for an assembly slot. It looks like I’ll get the boards back early July. I’ll be out of contact for a few days, I’m off to Glastonbury music festival 🙂

Boards back in Sweden

Well, I made it back from China with the boards and a lot of the parts. Now I’m going through the pricing and starting to kit for assembly…. New connectors seem to fit ok 🙂  

RevB PCB finished!

The Replay RevB PCBs have been delivered – they are still in China but I am heading over next week and will pick them up. Hopefully I’ll also get the last remaining components needed to build the beast…  

T80 update

Tobias has updated the T80 core to add undocumented DDCB & FDCB instructions. You can find the new version (v303) on the Library page.

68000 soft core debug

The PCB house unfortunately made a mistake with the impedance control on the Replay boards. They have re-made them now and they are on the way to Beijing where I can rescue them. The Chrontel DACs have also arrived at the distributor and are making their way here....

Replay RevB layout update

I have samples of the Chrontel DACs so I’ve decided to push on and build a few boards at least now. I’ve updated the schematic and layout drawings in the previous post and told the PCB house to re-process and complete the boards. Waiting for the components...

RevB assembly holdup

The RevB Replay PCB is waiting in China for some parts. For some reason a number of components are on two month lead time at the moment, which is a bit annoying. I’m trying to get samples of the missing parts so I can at least populate a few proto boards to test...

Amiga AGA up and running

The RevB Replay PCBs are currently being manufactured. We should have boards in 2-3 weeks. I’ll post more details of the new board over the next few days. Jakub has a demo of the board running Amiga with AGA available here :...

First look at Replay RevB

The RevB Replay PCB respin is taking shape. The main reason for doing this is to fix a Chrontel power issue. I’ve taken the opportunity to move the connectors to one side, and it has composite/SVHS output on the board as well now. The power has moved to the...

Happy Christmas

First of all, Happy Christmas and New Year to everyone. Wow, another month has gone by already. This ASIC project I am working on has had some last minute hiccups, and I am still very busy working on that. Mid Jan will see it done I hope, and I am going back to China...

Replay RevB schematic complete

Right, I’m back on the case. I’ve had quite a lot going on in my life, but things are settling down again now. I’m involved with taping out an ASIC which has one of the biggest die areas in the world, so it’s been very challenging and taken all...

Replay ‘B’

I’ve completed the PCB library work for the new parts. This was a bit more complex that I expected as I had limited data on some of the connectors. I have placed everything on the board and am working on the routing now. We are still discussing some changes to...
