Hi! I'd recommend you visit 8052.com and look around, and maybe ask some questions there. Note that the "chat" forum is NOT a real-time chat environment as has become popular in recent years. One word of caution ... do NOT use SMS-style abbreviations there, but, rather take the extra few milliseconds to type out the words in your questions. In fact, read ALL the instructions at the beginning of your session before you attempt to post anything, and be sure to search thoroughly before posting what may well be a repeatedly-answered question.
There are lots of opinions offerred there, including mine, and I suggest you take all of them with the proverbial "grain of salt." One relatively cheap board that gets little mention these days, is the NMIY-0031, which costs about $39.00 US. I've used this from time to time without being disappointed. Just search for NMIY-0031 on GOOGLE, and you'll find it. Read the fine print, though. This one has sockets for external memory, but will execute internal code if you "un-ground" the /EA signal, which you have to do surgically. I've been using one with a modified GAL that allows me to use a battery-backed RAM in place of a PROM. That's very convenient for many things. regards, Richard Erlacher ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, January 04, 2007 10:56 AM Subject: [Sdcc-user] Cheap Used Devel Board > > I bought an 8051 (89C2051) development board off of ebay a couple of weeks > ago, and I got burned pretty bad.
