Please Note: The information in this document has just been translated over from the printed version (14-Aug-98) and is being reviewed. There are errors! This notice will go away once all the obvious errors are corrected. From there, this document will be upgraded over time.
This document covers the subject that every Model 100, 102 and 200 computer cold starts ... where it appears that all files are lost. Don't despair. Don't panic. Armed with this information, you may recover your .DO files, easily. Includes discussions covering all possible options available. You will never loose another file.
Cold start! All your work disappears from your menu and the date reverts to 01/01/00! Don't panic. You may still be able to recover your text documents DO NOT start on a new text document! Immediately enter BASIC and type in the following short program:
OPEN "IT" FOR OUTPUT AS 1 FOR X=????? TO HIMEM : PRINT#1,CHR$(PEEK(X)); : NEXT
You should type this in without line numbers. Type in the first line, from OPEN through 1, then press ENTER. Then type in the second line all the way from the FOR through the NEXT, then press ENTER.
NOTE: Substitute the appropriate value for the amount of memory you have in place of the ?????. For a 32K M100/102 use ?????=32768. For a 24K M100/102 use ?????=40960. And for a T200 (in the 24K bank that is cold started!) use ?????=40960. Be very careful also to put in the colons, semicolons and parentheses where called for.
After you hit ENTER, the recovery process takes five minutes, during which nothing seems to be happening. Wait it out. When the OK prompt reappears, tap <f8> to return to the menu, and you will see the one document file "IT.DO". You may edit "IT.DO" using TEXT. There will be junk at the beginning and at the end. The junk at the beginning is the remains of your BASIC programs (if any). You may recognize a lot of the stuff that identifies them, like prompts or DATA statements they contain. Sorry, it is generally impossible to recover BASIC programs.
You use the <f7> key and the cursor keys to select the junk at the beginning of the file, up to the recognizable start of your documents, and then press <f6> to delete it. Now, move to the end of your recognizable text. What comes after is the remnants of your machine language programs (if any) and assorted other unrecoverable gibberish. Use <f7> and the cursor keys to select that stuff, and then use <f6> to eliminate it. Then copy one character from the text (<f7> ... select any character ... <f5>), to clear out the paste buffer. Now go back to the menu <f8>. You should see IT.DO reduced in size and the FREE MEMORY increased in size (depending on how many documents vs. programs and free memory you had before the cold start). Now you can go into TEXT again and either save the whole mess of documents onto a printer or tape or what have you, and/or you can cut and paste to chop the long document up into its proper pieces.
It is "very important" to periodically cold-start the 80C85 processor, i.e. Model 100, 102, and 200 computers--especially when you use them with machine language programs. It's good for the machine.
Cold-starting (AKA cold-booting, re-booting, etc.) is accomplished by holding down on the <shift> <ctrl> and <break> keys with one hand, pressing in and holding the <reset> button on the back edge with the other hand, then releasing the <reset> ... release the other three keys.
