That would be really cool.

I have added my 2716 mods and soldered in my 24 pin sockets. I decided to put the jumpers under the sockets, so that things are clean and "more permanent". There were no changes made to the bottom. I still need to add the jumper at W4, but I want to use wire wrap posts, so things can easily be reversed.

Looks awesome. I willl be doing a digikey order to continue my board build. Looking forward to seeing your progress.


Cheers.

Completed build (less IC chips)

Damn that looks sharp.
what is the mod you did by the serial interface?

Thanks!

The mod brings TTL level RxData, TxData, +5V and GND to 4 adjacent pins to connect to a USB or WiFi module.

Cool, looks like I will be doing the same on mine.

After Steve an I work on the colour interface for the 600 Rev D (mostly Steve), I will continue to work on my 502B and 540B boards.

Looking forward to more progress reports on yours. :0)

Finally all the IC's arrived and I had some time to tinker. Now I have to test it. /Jeff

If U11 is left unpopulated, the board will need a jumper installed at W1 so it can use the clock signal originating on the 540 video board.

While working through getting my 502 board to work, I discovered that there is a missing trace at U16, pin 14 on the Reproduction board.

See picture.
