Re: Apple //c Questions

[buggie@callisto.unm.edu (stephen e buggie)]

When connecting a 3.5 drive to a IIC,  _NEVER_ connect the old tall Mac 
400K drive model MO-130.  This drive is totally incompatible with Apple 
II, and there are reports that if connected to a IIC, it will zap the IWM 
disk drive controller chip that is soldered to the board.

The slim-line Mac 800K external drive (beige color) has a mechanism that 
is identical to the platinum Apple 3.5 drive and that mechanism can be 
transplanted into the platinum casing, with perfect compatibility.
(See my article, HACKING PLATINUM: MAC TO APPLE II" in the winter 1997 
issue of II ALIVE.)

: The //c had a number of internal revisions; the best way to check is to go into 
: Basic and type "PRINT PEEK (64447)" and press return (no quotes). If it says 
: 255, you have a very old //c; most of those motherboards had problems that 
: prevented most //cs from getting reliable serial communications on faster than 
: somewhere in the 300-2400 baud ranges. See your dealer about getting an 
: upgrade, which is apparently no longer free (tell them that the Apple 
: authorization number is ODL660, and try anyhow). If it says 0, you can connect 
: a 3.5" drive, but you don't have the internal memory expansion connector. If it 
: says 3, you have the internal memory expansion connector-- extra RAM can be 
: added with certain cards. If it says 4, you have the latest model of the //c. 
: If it says 5, you have a IIc+.
