Description: Just a picture of how I installed my Port Junior serial interface into my A1200. As with many interfaces the PCB is held in place within the case via self-adhesive velcro strips, although I decided to glue a small sheet of fibreglass board to the underside of the PCB rather than sticking the velcro directly to the PCB, so should the PCB ever come free of the velcro, there is no chance of the underside of the PCB shorting onto the A1200 shielding. The serial port cable is routed in the gap between the plastic case of the A1200 and the shielding. Note that the serial connector bracket at the rear right hand side of the A1200 seems to need to overlap out of the case slightly in order to get it to fit properly. Note the use of *proper* nylon edge insulation (Held in place with hot melt glue) around the hole beneath where the RAM shield would be located rather than the PVC tape as recommended in the installation instructions. BTW, the bag with the battery in it at the side of the expansion board is a replacement battery for the RTC function. The interface was recently purchased from AmigaKit (Thanks again AmigaKit!) and the latest version of the software for this interface can be found at www.vmc.de Picture Stats: Views: 1935 Filesize: 273.16kB Height: 768 Width: 1024 Posted by: Hodgkinson at May 12, 2007, 01:51:11 PM Image Linking Codes

| May 15, 2007, 03:03:00 PM makes good sense... thanks! |
| Hodgkinson Posts:1080 | May 14, 2007, 06:36:51 PM Thanks for the comments! Btw, the board there in the photo is a Blizzard 1200/4, no 68030 CPU (*Sigh*). As a matter of fact, I’m thinking of moving this RAM board into my (Disused) A1200T and putting the 68030 68882 board into the A1200 shown here. Might sound strange, but the A1200T really doesn't get any serious use at all, and the OS on the A1200T is buggered at the moment anyway. Re the battery. When I got the RAM board in the photo the original battery was totally flat, and at the time I didn’t have any suitably sized 3v batteries to replace it with, except for a much larger one that was far too large to fit onto the board. In order to allow this *far too large* battery to be used, it had to be extended off of the card (Hence the extension - Also allowing easy and much less risky battery maintenance) and the plastic bag prevents the battery from shorting onto any part of the case, or the accelerator board for that matter. It also contains any leakage, should the battery ever leak. …Come to think of it I haven’t ever seen a 3v cell leak, but its still better to use a plastic bag rather than to find half of the RAM board corroded away one day.

| May 13, 2007, 03:38:07 PM didn't the accel. have (originally) a coin-type battery? A question, out of curiosity reall....As far as I know (and I may be wrong) these are not prone to leaking...(or are they?) - why the elaborate extension and bag then? |
