Message-ID: Date: 10 Jun 91 17:24:02 GMT Sender: usenet@grape.ecs.clarkson.edu Reply-To: nelson@clutx.clarkson.edu (aka NELSON@CLUTX.BITNET) Followup-To: comp.os.msdos.programmer Organization: Clarkson University, Potsdam NY Lines: 29 I heartily recommend that everyone who programs on a PC look at helppc21. It's an online reference work for everything associated with a PC -- opcodes (through the '486), interrupts (dos, bios, mouse), ASCII charts, keycode charts, hardware descriptions (connectors, chips, bus lines), C functions, etc. It works from the command line, or as a TSR. Written by David Jurgens, it's a $25 piece of shareware. You'd spend at *least* that on just one book that wouldn't have one tenth the information. This is the first piece of shareware that I've ever registered -- the first one that I've felt was worth it. I found it on simtel20: pd1: HELPPC21.ZIP Extensive PC Programmer's information database I've also uploaded it to grape.ecs.clarkson.edu, where you can get it by modem. Grape is (315)268-6667, 12/2400 baud, 8N1, 24 hours. You may need to generate a break to switch to the right baud rate. It's stored on grape in: grape.ecs.clarkson.edu:pub/msdos/prog/helppc21.zip Same pathname for FTP and modem. -- --russ I'm proud to be a humble Quaker.
