They're all passable for single-sided PCB's (but actually toner transfer is the least reliable in my experience). They all really really suck for double-sided PCB's, especially if you expect any luxury like plated through holes. For me, far higher yield for double-sided PCB's comes from ordering boards over the internet. Generally you have to use (gasp!) a modern PC with Windows software, but other than that the experience is wonderful. I use http://www.expresspcb.com/ Keep in mind that I have nothing intrinsically against messy chemicals etc. (I like darkroom stuff too). But ordering boards their yield is so high (never once on many dozens of boards has there been a flaw). If you really want to do the toner transfer stuff despite all that I said, you can get 10 sheets of 8.5x11 from Circuit Specialists ( http://webtronics.stores.yahoo.net ) for $14.95, part number PCB-TTP.

Hi, I'm cleaning house and have the following equipment available. I thought I'd post it and see if there was any interest. If not, then onto ebay. 1). Intel ICE196PC (80C196 Emulator) installed in a Compaq Portable III PC (80386/20) with an Intel HEC Educational Demo board that lets you experiment with the software and emulator. This is a complete kit, with all the compilers, linker, locator, etc. It passes all diagnostics. The Compaq is 386/20 CPU, 42Mb Drive, 3072Kb of RAM. Everything runs under DOS. This comes with 196PC manual, diskette and CD with all the compilers. 2). Two Intel VLSICE96 Emulators (last ones with bondout chips). These pass some tests and fail others. This is not a clear indication that the emulator bondout chips are bad. Intel made many changes to the diagnostic software and the PAL's on the Crystal Power Accessory (Test module for Confidence tests). I don't have the information or the time to test. So these are buyer beware. I have one complete manual and diskettes. I can also supply all the compilers. Also note that the VLSICE96 emulator software used software timing loops (Intel was dumb) so you can only run these emulators on 8088/8086/80286/80386 PC's, those without internal cache memory. Slowing modern CPU's with caches does not remedy the problem. So if your interested make sure you have an appropriatly older PC. Please email me directly if your interested in any of the above. Robo
