LC1/2 Roms in a Macintosh II mainboard?

[uniserver]

hey guys i have a Macintosh II Mainboard here..

i'm about ready to do a re-cap on it. the only thing that might keep me from making it work is , the 4 ROM Chips are missing.

I know the LC1 and LC2 have 4 chips for rom same as the Macintosh II.

Can anyone think of a reason why maybe i should not run LC rom's in a Macintosh II main board?

I think I have a bad II board that I may be able to pull the chips you need.

 

[uniserver]

wow thanks man!

 

[uniserver]

still curious about the LC I / II roms though

 

[olePigeon]

I may have an extra set of LC ROMs you can have. I think I pulled them from one of my botched LC mobos. I'll need to rummage through my crap.

 

[uniserver]

no problem man, i could just pull some out of one of my dead lc-2's

hey i just realized the chip FDB UB13 is missing… might have been for air flowed off. or maybe it was never suppose to be there?

Isn't there solder points for a ROM SIMM socket underneath those DIP sockets? Desolder the DIPs and solder in a ROM SIMM socket, and use a dougg3 ROM SIMM!

 

[uniserver]

yeah there is

hard core.



i will think about it

Man you should change the Apple HMMMU (I think that's the abbreviation? It's that black thing.) to a Motorola 68851, so you have a complete set of Motorola purple-and-gold in there

Missing the IWM too it appears.

Apple HMMMU (I think that's the abbreviation? It's that black thing.)

Friend Comrade LCGuy advises that it's called a PMMU.

This is why I'm not allowed near 68020 machines. :lol:
