    Converting Acard AEC-7722 to AEC-7726

    trag, I've always had my SCSI ID's set to ID 5 v1.8 and v3.0 have shown a HDD on ID #5. I'm waiting for some Winbond EEPROMs to test v1.5 with HDDs. I don't want to overwrite my CD-ROM flash at this time. weedeewee, that is really interesting about having the flash data repeat itself...

    Converting Acard AEC-7722 to AEC-7726

    I have definitely run into a non-responsive conditions like that; I think mostly with rev 1.5 PCBs. Were you successful in sourcing the PLCC32 sockets? It should save hassle with soldering/desoldering. I personally think soldering on the socket is easier than soldering on PLCC directly with an...

    Converting Acard AEC-7722 to AEC-7726

    Perfect, thanks! I forgot to mention - for those who are going to modify their AEC-7722 v1.8 board for use with an 8-bit PLCC, you will need to rotate the PLCC 180 degrees compared to v1.5 and v3.0 of the PCB. This should be evident from the photo I included above!

    hello weedeewee! I like your simple idea for making those 16-bit TSOP firmwares. Fortunately, I've gone all 8-bit though. I tested my v. 1.5, 1.8, and 3.0 AEC-7722 units on a different computer today. Attached are photos of the 7722's with PLCC32 sockets installed. I used a variety of...

    Converting Acard AEC-7722 to AEC-7726

    trag, yes I tried the SE jumper. I noted this in my last eevblog post. I decided to update the eevblog post because I have been getting private messages about that thread. I suggest reading that final eevblog post, otherwise I just as well copy/paste the whole eevblog post here. Yup, I'm aware...

    Converting Acard AEC-7722 to AEC-7726

    I have also been working on this. You probably came across some of my old posts on eevblog while researching this. I have recently revisted this work and today updated my eevblog post to reflect recent findings. Because some people don't like cross-forum double posting, I will only paste a...
