I am looking for pointers to a (low cost) ROM monitor program for an Intel 8051 processor. I dont need anything fancy but it should at least: 1) handle power up reset 2) Initialize an RS232 port 3) display and modify registers and mem Break-pointing would be nice but is not a requirement. As always, source code is best but I'll take what I can get. A PD one anywhere? Any and all help appreciated. Ron Fletcher att!mtuxo!mtgzy!rlf

While all of the above is easily to write from scratch (with some help from the Intel MCS-51 Users Manual), everything you want to know (including source code examples) should be contained in the manual for the Intel SDK-51 System Design Kit, manual P/N 121588-001. There is a separate source code listing for the monitor eprom, but I don't see it in our binder with the SDK-51 documentation. While the SDK-51 uses an onboard display and keypad for monitor functions, it would be a lot simpler to use an external serial device. <> Larry Lippman @ Recognition Research Corp., Clarence, New York <> UUCP: {allegra|ames|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> VOICE: 716/688-1231 {att|hplabs|mtune|utzoo|uunet}!/ <> FAX: 716/741-9635 {G1,G2,G3 modes} "Have you hugged your cat today?"

Steve Circia has recently published diagrams for a complete 8051 development system in BYTE. It uses the PC parallel port, with simulator, etc. for a very reasonable price. It is called DDT-51, and was discussed in Vol 1., no. 5 of Circuit Cellar Ink, as well as August 1988, and September 1988 BYTE magazine. Steve Ciarcia no longer writes for BYTE, and so all further info on DDT-51 will be published in INK. You can get back issues of INK by contacting: Circuit Cellar Ink, 12 Depot Squre, Peterborough, NH 03458, or by contacting the BBS at (203) 871-1988. Usual disclaimer: I've got no connection to INK, I just think it's a great magazine. -- "Don't flame him, don't flame me, flame that fellow behind the tree." Via apple!mailcom, Fido 1:204/444

Just an addendum to Larry's article; the complete monitor listing is contained in SDK-51/MCS-51 System Design Kit Monitor Listing Manual P/N 121590-003 This document is very comprehensive (64 pages) and includes fully commented listings for both the monitor code and the SDK-51 assembler/dissassembler. -- Darel Mesher ...!uunet!mnetor!maccs!darel McMaster University darel@maccs.mcmaster.ca
