Replay prototype production continues

Prototype board production is continuing. All beta test boards are assembled and these have been shipping out over the past week or two. I’ve been in China and should get the production tweaked version as well as the atx-power control PCB manufactured shortly. The atx-power board connects the power supply in a mini-itx box to the Replay board, and has a on-off controller so you can use the case power button to power the board up and down.

A couple of videos of the board running. Sorry about the focus and exposure problems, the camera gets a bit confused by the changes in screen brightness.

Some demos:

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 tested now and I’m starting to send out more boards to beta testers. I’m having a lot of fun playing around with the Amiga core. You can see below it running up 1.3 workbench. I’m producing a video of it running some demos and behaving as a A1200 with AGA chipset and 68020 processor.

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 retro-computing. It softens the edges of the characters a little, but does reduce the colour distortion.
It’s easy to not fit the filter if we decide later it is not necessary.

Writing of production test is on going. DRAM is still not fully tested.
