The System 19 was the predecessor to what some consider Data I/O's most successful venture outside of the UniSite: The 29A/29B series. Depends on what software version came with it. Data I/O discontinued support for that unit about 7-8 years ago, so updates (even if you could afford them -- DIO has a reputation for being very pricey) are no longer available outside of other System 19 owners (I'm not one -- I got lucky some years ago and grabbed a UniSite). Yes and no. You can use it to read PROMs, and then (with the right commands and hookup) transfer the data to an attached computer. That connector is standard RS232, DCE if I recall correctly. That's no surprise. They can also be very snooty if they think you're not a big spender. They've been getting a little better in the past year or so, but they've still got a long way to go. Best I can suggest is to dig around on other sources you may have for used/surplus test gear. Even the big names, like Tucker Electronics, may have some old manuals they're willing to part with. Ideally, I would look around and see if you can find a 29B chassis. The 19's a rugged old workhorse, but it is just too darn old for much of the stuff out there. Worst case, I (and at least a couple other folks on the list) offer chip programming and reading services. If you've got something you desperately need programmed, read, or archived, let me know the device number and I'll tell you if I can do it. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) (Web: http://table.jps.net/~kyrrin) SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.
