 David,
  I'm sorry it has taken so long to reply, but I have trouble getting 
 onto this bbs, but to answer your queries:
 1) how much RAM?
  The Amount depends on the application but it uses most of zero page,
 & needs about 256 bytes above & beyond that!
 The KERNEL is 3K $F400 -> $FFFF
 The Development rom is currently just over 8K Assembled to anywhere 
 you like on an 8K boundry
 So you would need a 16K EPROM

 2) HARDWARE NEEDED?
 I have currently got it set up as 32K RAM $000 -> $7FFF, and 16K 
 EPROM @ $C000 -> $FFFF
 I have also used other Configurations allowing to compile into ram @ 
 $C000 - $EFFF so as I can ROM the code
 3) Mass storage?
  It does not as yet support any form of MASS STORAGE, But I am toying 
 with the idea of setting up a RAMDISK setup using BANK SWITCHED ram 
 which I am supporting in the code.
 4) Cost??$$
  I think that around $250 AUST. will be the going price.
 ?) I am currently developing HARDWARE which will support the forth to 
 the fullest & am currently using a HACKED board which I designed about 
 12 months  ago!

 Hope to be selling a development system, both S/Ware & H/Ware in the 
 near future for about $600 AUS. roughly!

 If you are aquainted with the 65F12 you will have a little more of an 
 idea of what this system is like!

 HOPE IT HELPS & CULATER :-) ..GregF..
