Toner as PCB resist (perilously close to OT)

by compoobah＠valleyimplants.com

A while ago (late '80s, early '90s) I heard a suggestion for using copier toner as PCB etch resist (draw on paper, copy onto overhead transparencies, iron onto the PCB). Now that PCB layout software is available easily, as are laser printers, has anyone here tried it? I'm wondering how well it would resolve for finer-pitch DIP/SIP packages, or if the etchant would eat through the traces.

ARM Microcontroller evaluation boards

by cclist＠sydex.com

I know that this is sort of OT, but I also know that several folks who do embedded development lurk here. I have a possible application for an embedded controller with a fair amount of RAM 128-256K and ideally, DMA capability. Originally, I considered something like an 80C188, but it seems that that's yesterday's technology and better alternatives exist. Right now, the ARM controllers look pretty good. Can anyone recommend a favorite development board that can be used for prototyping? I don't need much program memory--128K is more than adequate, but at least 128K of RAM is very important. Cheers, Chuck

Diablo part numbers?

by rtellason＠verizon.net

I snagged a big old diablo daisywheel printer here the other day, pulled the boards and mechanism out, and got rid of the case etc. right off, so there's no model number, which I probably should've written down at least :-(. Anyhow, I'm finding good numbers on the transistors and such, but a lot of the chips all have what seem to be diablo part numbers on them and not a whole lot else. Anybody know where I might be able to cross some of this stuff over to find out what it is? -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.
