I know some good ways to do this and some things to avoid. What you will need no matter what is a modem program on the //c. I recommend ProTerm as it is easy to use. On the Mac, you can use the Clarisworks communications document form of uploading which is fairly easy. You could also use a telecomm application like ZTerm, but since you've got Clarisworks, you might as well use that. It eliminates one step for you as well. I can help you set up either of these ends if you get that far and need some help. You will need a null modem serial cable or a modem with each computer and two phone lines in your house. But, depending on which //c you have, there might be limitation in using a serial cable. Read the following info and then check to see which version of the //c you have. IIc info ======== Four models of Apple IIc were made from mid-1984 through 1989. Some models can be identified by the color of the external plastic casing but mainly they are distinguished by special features. ORIGINAL IIC: (1984-85) White casing; does NOT operate an external Unidisk drive; has NO internal self-test. Most numerous type made. Has 16K of internal ROM. ROM code: 255 This model has a defective timing crystal, which limits modem use to the slower baud speeds (300 baud, or, if lucky, 1200 baud). This does NOT affect all original (ROM 255) Apple IIc models. Only those produced between April 1984 and up until around December 1984. If your IIc reports it has the original ROM revision, you should not automatically assume it has the faulty serial ports. If you open the case and look at location C-7 on the motherboard, it'll either have a 74LS161 (black) DIP chip or a silver colored oscillator with MHz rating. If you find the latter your motherboard has the "good" serial ports part. The free motherboard upgrade is no longer available. The keyboard was made by Atlanta Photocircuits Co.; its keys are prone to "stickiness" which slows typing speed. An improved keyboard was introduced for the Unidisk 3.5 IIc. UNIDISK 3.5 IIC: (March to Sept 1986) White casing; externally identical to ORIGINAL IIc. Can operate 800K Unidisk 3.5 from drive port; can also operate faster modem speeds (2400 baud; possibly faster). Has built-in SELF-TEST: Hold down both Apple keys firmly, then turn on power switch; checkerboard display pattern fluctuates for two minutes, then displays SYSTEM OK in center of screen. (Any defective ICs will be identified by a displayed code.) Has 32K of ROM. ROM code: 0 If PR#7 is typed on this model, then the screen message, "APPLETALK OFFLINE" will be generated in response. MEMORY EXPANSION IIC: (1986-87) Platinum grey plastic casing; has all features of the Unidisk IIc, plus special feature that there is a motherboard RAM-connector socket so that a one megabyte RAM memory board can easily be installed (Pre-owned Electronics (MA) offers these Apple ram board for $39. Two subversions of the Memory Expansion IIc were made: ROM 03 and ROM 04. There are no important differences in performance between ROM 03 and ROM 04; the shift to ROM 04 was done to repair an arcane bug in the ROM firmware of ROM 03. Most users will not notice the difference between ROM 03 and ROM 04. NOTE: RAM memory boards can be installed in the Original IIc or in the Unidisk 3.5 IIc, but installation is complicated. Fitting extra RAM in either of the two earlier IIc models requires removal and reinstallation of two large 40-pin IC chips: the 65C02 microprocessor and the MMU memory management unit. The socket-connector inside the Memory Expansion platinum IIc is much more convenient (Statt, 1987). APPLE IIC+: (1987-89) This was the last version of the IIc family. It is easily identified externally: platinum grey plastic casing; power supply is fully internalized in the computer (i.e., no "brick on a rope" power supply as in all earlier models); internal 3.5" 800K disk drive (5.25" external drive can be connected as an option); built-in 4 MHz accelerator (all earlier IIc computers operate at the standard Apple ][ speed of 1 MHz). Speaker volume control moved to top panel, above the keyboard. Back panel serial port connectors were changed from the 5-pin DIN sockets used on previous IIc models to the mini-8 connector used on the IIgs or the Imagerwriter II printer. ======================================================================== Most IIc models can be identified by external appearance: The external plastic casings of the Original IIc or the Unidisk 3.5 IIc are white, while the casings of the Memory Expansion IIc or the IIc+ are platinum grey. The IIc+ is the ONLY IIc model with the 3.5" disk drive built into the casing. The only two models that are externally IDENTICAL in appearance are the Original IIc and the Unidisk 3.5 IIc. The quickest way to identify which model you have is to activate the "self-test": Hold down the two Apple keys, then turn on the power. If you get wavy lines scrolling downward, then you have the Original IIc (too bad!); but if the checker- board pattern of the "self-test" appears, then you have the Unidisk IIc! IDENTIFYING THE IIC MODELS VIA ROM TESTS: These are two simple keyboard tests by which the motherboard type is identified conclusively by checking its "identification byte" at ROM location 64447, known also as location $FBBF in hexidecimal notation. You type in the following coded messages, then note the computer's response. The response tells you the model of IIc you have. Either test is sufficient; both tests will give identification results that match. (ROM identifier tests are unnecessary with the IIc+ because the IIc+ differs noticeably in external appearance from all IIc models.) (1) First, get the "Basic Prompt" symbol, ], by holding down and releasing these two keys: . At the Basic Prompt ], type PRINT PEEK (64447) followed by . How does the computer respond? If it responds with "255", then you have the Original IIc; if it responds with "0", then you have the Unidisk 3.5 model; if it responds with "3" or "4", then you have the memory expansion IIc. (2) The second ROM identifier test is similar to the first. Again, get the Basic prompt by holding down and then releasing the and keys. Then type CALL -151 followed by . The computer will respond with an asterisk *, indicating that you are in the "system monitor." Then type FBBF followed by . If the computer responds with FBBF- FF then you have the Original IIc; if it responds with FBBF- 00 then you have the Unidisk 3.5 version, and if it responds with FBBF-03 or FBBF-04, then you have the memory expansion version. Apple no longer offers the free upgrade for the original IIc. -------------------------------------------------------------------------- (Back to the letter) In my case, I have the old "255" ROM, and I couldn't get the serial cable to work at all at any speed, so I resorted to using my 1200 baud modem from the //c to my GlobalVillage Teleport Platinum modem using the two phone lines in my house. This doesn't mean you wouldn't be able to get a serial cable to work on your //c even if it's the "255" ROM version. It should work somewhere from 300-1200 baud and this is the best thing for you to try first. The cable should cost $10-$15. Next, I had trouble with transferred files having certain characters come out wrong, even using the ClarisWorks translator and it was explained to me that there is nothing you can do directly to remedy this. Not to despair though, there is a simple solution. Try the following: 1. Transfer the AppleWorks file to the Mac using XModem. When doing the file transfer, make sure you have any options to do with "text translation" turned off. The file must be transferred in binary mode, without affecting the contents (this is what most programs do for a standard XModem transfer). If the Apple II communications program supports any special file transfer options such as "Binary II", make sure they are disabled. 2. Use a utility program on the Mac to change the received file's creator to 'pdos' and the file type according to the following table: AppleWorks Database (ADB): '19 ' AppleWorks Word Processor (AWP): '1A ' AppleWorks Spreadsheet (ASP): '1B ' Each of these file types are a two-digit number in base 16 (hexadecimal) followed by two spaces. The creator and file type are case-sensitive, so make sure they are entered exactly as describe here (without the quote marks). There are many programs which can set the file type and creator. ResEdit is one example, though it is overkill. I recommend using Snitch, a very simple and useful little shareware utility that uses the GetInfo window to allow you to change file types and creators. It is readily available on Mac software download sites on the internet. 3. Open the files with Clarisworks and they will translate with the Appleworks XTND into Claris format. I found that they are translated perfectly this way. I just transferred about 25 disks full of files of all three Appleworks file types with this setup. Please let me know if you'd like some more help. Various persons were very helpful to me in figuring this all out and I have quoted some of their info here, but it took months to get this all figured out and completed. I'd gladly spare you that ordeal. Good luck! Douglas Frederick douglas@blarg.net Seattle, Washington
