As for Monitors, most folks appear to be using UT4, IDIOT, Chuck Yakym's MCSMP, or ELF2K. The first 3 have similarThanks for the monitor comparison. I need to spend some quality time looking over the options. I'll probably borrow from everything and cobble something together.
I really want to be able to load the Intel HEX dump fromat from the assembler directly, rather than having to use the UT4 !M interface for that.
I like the labels on the underside of the chip sockets. How are these done??I'm using the plastic Wrap-ID's where I could get them. But they are expensive nowadays, so I won't be buying more.
The paper ones are just done up in Inkscape, and then stuck in place with a piece of two-sided tape - I have a roll of very narrow tape for this.
This is just a by-product of my layouts. I design a full detail layout in Inkscape, and then also flip it over (reversing all of the text again) so I have both a TOP and a BOTTOM view.
For example, from the VIS build:
Printing an extra copy of the bottom view gives me the labels to cut out.

Please tell us more about the Logic Analyzer!Just like you can get very cheap scan converters today, you can get very check logic analyzers. They are built using a little MCU development board, but with Logic Analyzer FW added.
This one I found on amazon.co.uk (I'm in the UK) from Hobby Components Ltd for about £16 (~ $20).
The board is basically just and interface card - all of the processing happens on the laptop using the open source package sigrok.
Nothing fancy, but get's the job done and cheaply.
