Re: WHOOPS ! (oh not not him again)

That is one nice looking board! I think using 2764-27512 is a good idea, and I'd like to expand on that by asking if it would be possible to include the 28/29F010/20 as they have basically the same pins as the 27512 save for the Vcc and the 4 extra pins. I think they would be even easier to find (I ...

Don't hate me :lol:

Assembly debugging sheets

I found myself trying to debug some 6809 assembly routine of mine, surrounded by register values and notes on random pieces of paper all over the place and thought that there may be a better way :lol: So I created some nice sheets with columns with register names and space for notes. As a bonus, the...
