Howdy,
	I have a few questions about Peter Dunsters F1 board.

1) What is a DS1233?
	This part appears on the schematic as having no inputs and only 
	one output which is tied to the XIRQ pin of the 6811 chip.
	I can't seem to locate it in data books. If I knew what it was
	then mabey I could search by discription rather than by number.

2) Can I use a 64KX8 RAM instead of a 32KX8 ?
	I don't need the extra address space, its just that a 32K by 8 
	RAM seems to be obsolete! I can't find them. A 64K by 8 is very
	common and I wonder if they are pin compatible. Could I plug in
	a 64KX8RAM into the 32KX8 slot and have a usable 32K of memory?


	
	I would like to thank Peter Dunster and Daniel Mauch for very 
prompt delivery. I ordered the F1 board from Daniel and it took 4 working 
days for my check to leave my house and the board to arrive at my door. 
This service is awe inspireing to me since I am one of the unfortunates 
to experience the Greg Ratcliff 5 month + (and still counting) Miniboard 
Delivery System.
