No worries, I completely understand.

I'm no compiler expert and since I don't fully understand the dags, I decided to take the plunge and invest in the avocet compiler package. expensive, but should be worth it in the long run for larger experiments that I don't want to code in assembly.

Hi Toshi,

It's been a while, and I've gotten distracted, but I never quite forgot about this I was wondering if you ever found those extra macros you had mentioned.

Hi all,

Free is a relative word here with regard to Eagle.

Limited to 2 signal layers, 1 schematic sheet, 100mmx80mm routing area on a pcb. So, if you're working with small projects, it is great. But if you want final boards >~3.5"x~2.85", you either need to pay for it or find something else.

For ...

Hi all,

I've recently come into posession of a bunch of surface mount IC's (came in the same box with all of the PAL's and GAL's I got) - I'm sorting them out and I think I'd like to use a few of them if they are what I think they are, but I am not sure, and I'm not sure how to tell what the part ...

Cross-32 due to recommendation from Garth, and I've been VERY pleased with it as an assembler.

Is there a way to tell if a PAL has been programmed already?

Hi all,

I came into a good collection of IC's, some of which I think I would like to use in a 6502 or 65816 system. I have a few problems I hope someone can help me with.

One is that I have a new set of PAL's and GAL's. I know that these are probably OTP IC's, but I don't know how I can tell if ...

I just wanted to post an update. I got my "enhanced willem programmer" the other day and I've played with it only a little - mostly reading, erase, writing and confirming to an Atmel 29c256-70 flash module. It has worked quite well so far.

It is cheap tho - no pretty case, pretty much an exposed ...

Hi all,

Let me be clear on something - audio was just an example - it's a scheme I'd like to use for several things if possible, including, but not limited to data recording and shared video ram. I suppose audio was a poor choice to put forth as audio is sooooo slow, it would be easy to do on a ...

Hi Garth,

I've been thinking of the dual port but I was thinking of having a fairly large buffer - between 64K and 256K - and the dual port chips are just sooo expensive, a 32kx8 is about $28... I was hoping to get it a bit cheaper, or to find some other solution...

kc5tja: Conveniently enough I'm ...

Hi all,

Does anyone have any reference on how to share ram in a system? For example - let's say I want to pump some bits to an dac to output some music - so I have another circuit that cycles thru an address range to get the audio bits out.... My question is how to connect that ram into my main ...

Hi Gurft,

I've been using an EMP-10 programmer from Nedhams, nice programmer, but not really cheap (current versions are better of course, mine which is older is dos only, current ones have windows support) - they start at about $300 ish I think.

I'm waiting for one I got on ebay the other day ...

Hmm, you don't by any chance still have that macro file floating around somewhere, do you? or perhaps remember which register, A or X had the lsw and msw?

No problem Toshi,

Take care of yourself first, this isn't nearly as important, and definitly not life threatening .

I hope you feel better!

I assume in terms of the assembler, you mean ja.

I played with it a few moments ago and it seems pretty straight forward, just run ja <filename> and it will create <filename>.o65 which will then need to be linked using the jl65 tool....

I did find a few docs, although I'm sure you already knew ...
