Hello,
I have a very simple question , but interesting though.
When you expand the memory of your 1040 STE with SIMM slots
( ie you have 4 x 256K SIMM modules ) to a 2 Mega-byte system
( ie you have 2 x 1M SIMM modules ), what are the two slots
that should stay unused among the four ?
On the board of my ST I can read near the SIMM slots :
U 600
+-----------------------+
| simm slots |
+-----------------------+
U 602 | |
+-----------------------+
U 603 | |
+-----------------------+
| |
+-----------------------+
U 601
Any ideas ,

The Atari only need 8 bit , 150ns, the other bit in the 9 bit ones is wasted, but then they could be used in a PC. Just a thought.... -- Roger W. Sheppard 85 Donovan Rd, Kapiti New Zealand...
