As some of you may have noticed, I've been writing a series of DIY Atari 8-bit hardware articles for Excel magazine.
For Issue #4 (due soon) I've contributed articles on both the Pixels Past 8k and 16k EPROM based cartridges, and also building instructions for my own latest design, the UnoCart.
Building your own UnoCart is not massively difficult and involves just a small amount of easy (thru-hole) soldering.
The key item is a STM32F407 Discovery board, which is readily available from most electronics suppliers for <£20. Using an off the shelf arduino-like board avoids almost all of the difficult soldering.
The only hard to get item is a Atari cartridge breakout board (pictured). The article describes how you can get these made from the provided files yourself from a PCB manufacturer (a batch of 10 can be obtained for not much more than £10 from the cheap chinese suppliers), but I thought it would be easier if I offered some spare ones here. These are suitable for XL/XE machines.
So, if anybody is planning to work through the project in Excel magazine (and wants to get ready in advance), then I've got about 8 cartridge breakout boards spare and available for £3 + P&P. Please reply here if you want one.
Can I ask that anybody asking for a board confirms they have already reserved their copy of issue #4 of Excel magazine, since I'd prefer these boards to go to readers of the magazine.
