Re: [xl7] FLASH SIMM update

2011-01-01 by Jack Pratt

There is the slot that the SIMM is actually in (should be slot 0) which is the physical slot, and obviously you can't have two SIMMs in one slot, and then there are the other slots which can be emulated or not depending on whether you have other ROMs you want to use [you can just emulate all the slots, but then everyone would start selling their excess SIMMs and the market would lose its bottom].

So you can use other SIMMs if you like. But the other reason for the DIP switch is that there are 7 ROM regions, and only four slots and you wouldn't otherwise be able to make use of all the FLASH (its quicker to flip a DIP switch than reprogram the SIMM). So you can have the SIMM programmed as you wish and make what use of it you like, but the option is there - you just don't have to use it. [I'm pretty sure that people will not buy the FLASH SIMM just for this feature ;-) ]

===================

so each slot can be emulated independently...?

i would have thought that this would only use two DIP switches just to
facilitate emulating consecutive slots:
0x00 - no emulation
0x01 - emulate slot 1
0x02 - emulate slot 1,2
0x03 - emulate slot 1,2,3

in any case, i'll probably just have it set up to emulate all four slots.
my orbit-3 chassis is waiting for this.
