Chue's TF534 Build

Just started my build. So far I've put on both CPLDs, the 3.3 V regulator, and the resistor networks (all 1K arrays).

The regulator, resistor arrays, and small CPLD were leftover parts from my TF530 build. I took a risk and am using an eBay used part for the larger CPLD.

With these things on I was able to identify and program the CPLDs. Now I am waiting for other parts to arrive from Digikey.

Aren't the resistor networks 2.2k for the TF534 and 1K on the TF530? Just know they are harder to swap once everything is on there.

both work. Quaranteed.

I've put on some more components on the top of the board:

10uF caps
Shmitt buffers
Bus transceiver
Resistors R1 & R2 - outlined in yellow in the image. Are these in the correct place? The silk screen is hard to read.

It's mostly finished, just missing the SPI flash.

Final Specs:

68EC030 (RP40B) CPU
68882 (FN40A) FPU
40 mhz clock
4 MB of RAM
4 GB CF card

Here is some TF 534 eye candy:
