First, Is there any reason why i can't use a 27C512 in place of the 27C256 in my ecm (1227730) and just only have them half full. I can get free 512 chips from work.

Secondly, I've been trying to get the ALDL monitor from this page http://pweb.de.uu.net/pr-meyer.h/aldl.htm
working but im getting runtime error 200 from it in windows, and in plain dos boot it just hangs. I've e-mailed the author. Is anyone using this software on the 730 succesfully? Other free options for the 730?

Thanks

27512's should work, just make sure to load two copies of the bin in the chip. Exactly the same as I do with a 7165 ECM, but I use 27256's where it originally used a 27128....

Have you tried Craig Moates ALDL monitor, it should work with the 730 as well, but I haven't heard of anyone actually using it with 730 yet?

I'm curious as to why you use two identical copies of the 128 data in the 256...

I ask because there is another thread here that advocates loading the 128 data in upper memory on the 256 chip, leaving the lower 128k FF'd out...

Is there a specific reason for the "piggyback" code, versus the "load high" code???

ZaphodB

Suppose the highest address bit is not connected to either VCC or GND, then you can't be really sure wether it's going to address the high or low memory bank, and having the same date in both is just an insurance against that possible problem.

Sarkee

Then it's more of a "fail-safe"...

OK; I can relate to that...I guess now I'd ask, what method do you use to "stack" your two data blocks???

ZaphodB

In my case the bin is 16384 bytes = $4000 hex in size, so I first load one copy at buffer address 0, and then another one at buffer address $4000. But I don't use a pocketprogrammer, since I have one of those $2000 EPROM Burners since back when I had my own company and was working with electronic hardware design....

Sounds like a sweet setup!

I was wondering if Pocket programmer allowed you to make two 128 passes on a 256 chip; one high, one low...But I doubt it...

I'm curious (read: I will try) as to whether a simple "copy /b a.bin+b.bin c.bin" would work...After all, they're binary files already...

Otherwise, I'll use UltraEdit to make a "stacked" file...

But I'd sure like to cut down the number of progs I need on my laptop (a recycled 486 dx66)...

I do the dos copy /b 00.bin+arap.bin=burnme.bin operation to burn my 128k image into a 256k flash chip and it works fine.

It really doesn't matter what is in the lower half, just the upper half. Doubling up the bin is just a simpler method as you do not have to create x'00 or whatever bin to go into the lower half.

Some people have found that ONLY x'00s on the bottom half will allow the 29C256 Flash Prom to work properly. This MAY be just a Flash Prom/Pocket Programmer issue with a particular version of FILEPROM.EXE that they are using.

I am noticing some "inconsistencies" when using a 29C256 Flash Prom/Pocket Programmer/FILEPROM and certain computers. I noticed this on the two different notebooks that I am using, and I use $8D which fills the entire 29C256 Flash Prom.

My suggestion is to try one method, and if you encounter problems, try the other method. When you have a method that works for you...use it.

Unless Craig has updated his software, it doesn't log MAP value, which is essential for the '730. Of course, I'm sure that will be addressed in the next version.

i'm gonna download craig's software tongight and try it out if i get a chance. I'll post results. Thanks for the info.
