莱迪思 GAL 和 ispGAL 芯片的替代品
上学期我选修了一门关于嵌入式硬件编程的课程，主要是使用Lattice和ABEL的GAl芯片来编程。 我想在课堂之外继续这样做以获取乐趣，但由于购买程序员的成本高昂，我发现成本过高。
是否有任何免费或低成本的方法可以对类似于 GAL 芯片的东西进行编程？ 请不要建议 AVR 或 PIC 芯片，因为我的主要项目是我想用较小的芯片实际编程和构建 CPU。
我研究过 ispGAL 芯片，但对它们进行 ISP 编程的电缆（至少 USB）要 150 美元或更多。
感谢大家的帮助！
I took a class last semester about programming with embedded hardware, mainly using GAl chips from Lattice and ABEL to program them. I'd like to continue this for fun outside of the class, but I find things to be cost prohibitive due to the high costs of buying a programmer.
Are there any free or low-cost ways that I can program something similar to a GAL chip? Please don't suggest AVR or PIC chips, as my main project is I want to actually program and build a CPU out of smaller chips.
I've looked into ispGAL chips, but the cables to program them ISP (USB at least) are $150 or more.
Thanks for any help guys!

尝试一下 Xilinx 评估板，教育版的评估板相当便宜。 而且你还是个学生！
我猜测，根据澳元价格，150 美元，加上所有工具，大约需要 100 美元。
这有点贵，但该芯片足够大，可以在门上安装一整台计算机。
该评估板具有以太网、PS/2、串行、USB 和 VGA：它们都连接到门阵列！
Slipway真的便宜吗？

Try a Xilinx evaluation board, the education priced ones are pretty cheap. And you're a student!
I'd guess based on the AUD price, of $150 about USD$100 with all the tools.
This is a bit pricey, but the chip is big enough to do a whole computer in gates.
The eval board has ethernet, PS/2, serial, usb and VGA: and they all connect to the gate array!
For really cheap, Slipway ?
