Sender:ephram@violet.berkeley.edu My high school had(still has?) an 1130 with 4K 1402reader/punch and an 1132 printer. I couldn't get enough info on this baby. I even wrote IPL cards for the thing. One card into the hopper IMM STOP, RESET, PROG LOAD, in goes the card. There were a few that I created (no easy job getting the multiple punches necessary for one of those things) one turned the console into a card punch so you could use the machine for something if your disk was out. I even made one that looked like the COLD START card but instead if you put a deck behind it, it would punch out all the holes in your deck. The punch almost never got beyond the //job //for //ioctl ... cards (people would always remove their deck from the hopper). The resultant chips were always great at parties though. ephram@violet.berkeley.edu

I've been reading all this stuff about the old beast, but thought I should add my 2 bits. Writing COLD START cards was a big thing for a while. Some of the ones we produced: 1) RABBIT - similar to the one you describe, except that it reproduced itself on all the cards in the input hopper. Slip one of these in the COLD START box, and wait. Cold start cards were fragile, cuz they had so many holes out, so sooner or later someone would get to the rabbit card. Usual practise was to put a cold start card at the front of your deck and IPL. People didn't catch on to this as fast as the 'punch all holes' one cuz it made sort of a rippling noise rather than the KERCHUNK-KERCHUNK that you got if you punched out all the holes. Needless to say RABBIT cards were quickly outlawed. 2) 1132 'Music' - make the printer make horrible noises as it fired all hammers at once, as fast as it could. 3) FATAL999 - the standard COLD START read the bootstrap in from block 0 of the disk, but block 5 was unused. So we wrote a program that copied a little program onto block 5, and a cold start card that swapped blocks 0 & 5. So, just before going to supper when your best friend was coming on shift as student operator, you'd run this one through, leaving the system apparently dead; the operator would come in a little later, run a cold start, and get a message: ZZZ999 - FATAL SYSTEM CRASH Created a nice sense of panic, and totally harmless (unlike the RABBIT). Sigh...seems like only yesterday. A lot of fun, and a good learning experience (a friend wrote his first assembler so he could produce COLD START cards). > >ephram@violet.berkeley.edu ../Dave -- ../Dave Mason, TM Software Associates (Compilers & System Consulting) ..!{utzoo seismo!mnetor utcsri utgpu lsuc}!tmsoft!mason
