Myron,

if the Z-100 has a MAX of 192K (old motherboard ICs, old or new type MB):

SW1:  76543210      SW2:  76543210
      01100111            11111100

Be careful, as the switches are actually in reverse order on the board.

If you have 256K chips on the motherboard, you will damage the board and
the Z-100 RAM system if you use the Z-205 below 768K.   To use the Z-205
as a 256K RAMdisk above 768K, use the modifed RAMDISK driver from the PD
LIB disk set (that program is not yet on SIMTEL20, but I'm working on it).
I think the ASM source includes switch settings for 768K, I'll check.

Cheers,
Gern
