3 Sept 2015 update: the schematic is almost done.
Log from Rasky, raspberry pi 2 KVM over IP
The most relevant change is the CPLD that is changed from MaxII EPM240 do EPM570.Details and schematics on https://www.nexlab.net/2015/09/03/rasky-update-schematic-almost-complete/

New PCB will support EMP240 and EMP570 CPLDs...
Log from Arduino + CPLD = CPLD Fun Board!
I've just finished the new PCB revision: With eight solder jumpers (SJ1-8) it is possible now "configure" the board to use an EPM240T100 or EPM570T100 CPLD (the idea to allow the choice between an EPM240 and an EPM570 was suggested by Hacker404). In...

Getting back to it.
Log from TRS-80 Compatible Clone
I have been away for a while. In that time I have started using a different computer. I don't know how much is recoverable from the old one. I now have the Altera and Xilinx platforms on my laptop. I re-did some of the VHDL. I found that the character...

Tested the EPM570 PCB version!
Log from Arduino + CPLD = CPLD Fun Board!
At last I've assembled and tested the EPM570 PCB version: In the back of the PCB there is a short reminder about the solder jumpers you must use for the EPM570. In this case you need to populate C31 and C35 too (see the schematic). Of course in the Quartus...

Preparing to use the Altera CPLD
Log from Z80 Retro Computer (With Graphics)
I started checking the Altera CPLD boards I bought on ebay. These are the boards - Both boards are identical. The only difference being that one has an EPM240 chip and the other has a EPM570 chip. Unfortunately they shouldn't be identical as the EPM570...

A Wire-Wrap test bed.
Log from TRS-80 Compatible Clone
OK, this log will take a couple of days to get through. I have work out the timing which is complex. The original TRS-80 had separate Character ROM and separate Video RAM. I intend to use only one ROM (FLASH) chip and one (S)RAM chip. So the FLASH will...

Logic Analysers, CPLDs and Dunning-Kruger
Log from The Last Psion
It’s been a few weeks since my last update on this project. This is partly because I’ve been waiting for a couple of bits to arrive, specifically a logic analyser based on the CY7C68013A and an Altera MAX II EPM240 board. But to be honest, the delay...

Log from VGA videocard for microcontrollers
Sometimes, when making your own devices on microcontrollers, there is a need to display huge amounts of information on a display and to use a bigger screen for ease of perception. Unfortunately, there are no ready-made and budget-friendly solutions for...
