ram error &4600 - which ram chip

[Ravage]

Hey all<br>
I got a program on my bbc from <!--EZCODE AUTOLINK START--><a href="http://www.swattons.freeserve.co.uk/bri ... <!--EZCODE AUTOLINK END--> that says I have a RAM error <!--EZCODE EMOTICON START :( --><img src=http://www.ezboard.com/images/emoticons/frown.gif ALT=":("><!--EZCODE EMOTICON END--> <br>
<br>
I've suspected this because most of my games arent working, and trying to send the machine bbcXfer crashes. What games do run seems have have "RAM dots" i.e. bad ram locations on screen<br>
<br>
Brian's programs says the errors at &4600 - can anyone <br>
1. translate this into the ram chip / pcb location / does anyome have a memory map to ram chips in a bbc B<br>
2. got any spare ram chips I could buy / tell me the spec of them<br>
<br>
Ironically I repair arcade games so doing the desoldering and fixing is OK, but working a memory location to a chip is beyond me <!--EZCODE EMOTICON START :( --><img src=http://www.ezboard.com/images/emoticons/frown.gif ALT=":("><!--EZCODE EMOTICON END--> <br>
<br>
Thanks for any help <br>

Ok. &4600 somehow worked out to be IC53. Changed. and now it works. YAY!<br>

How did you work out it was IC53? Did you find a mapping table somewhere or did you just slowly swap out each memory chip one by one?
