I have two questions regarding the Subject: 1. Does anybody know a valid address for (from uunet): From attcan!uunet!convex!killer!texbell!merch!cpe!hal6000!trsvax!trsvax.tandy.COM!uhclem Tue Nov 22 01:35:09 1988 From: uunet!convex!killer!trsvax!uhclem (Frank Durda IV) Frank Durda IV @ <trsvax!uhclem> ...decvax!microsoft!trsvax!uhclem ...sys1!hal6000!trsvax!uhclem Simply reversing the 'From' address doesn't seem to work. (Better still - "Frank, you there?") 2. Does anybody have a public domain version of a RAM Swap driver which will use >1Meg RAM? I have 9Meg of RAM boards wired into my 6000 and would like to use them somehow. I DO know about the new MMU driver from Tandy but (what else ;-) the $$ don't justify it for my home system (yet!). I am running XENIX 3.2 if it makes a difference. Thanks in advance! ----- uunet!attcan!utzoo!tls!mbeast #include <std.disclaimer> Michael B.

I DO To save the network excess gas, I will respond briefly here. You can't put 9 meg in due to the memory address space being restricted to 7 Meg (plus perhaps 512K). This is not a 68k restriction. It is a design restriction of the Model 16/6000 which divided the 16Meg into two address zones. One bypasses the offset and limit registers (USER) and the other doesn't (SYSTEM). Take away another portion of a Meg for the memory-mapped I/O space and you are at 7 Meg. Besides the provided power supply should be smoking by now, unless perhaps you are using someone else's box. <This information is provided by an individual and is not nor should be construed as being provided by Radio Shack or Tandy Corp.
