    You're right, they're not still in production but they handle every
EPROM, PAL and PROM that I'm interested in so what's wrong with them? The
fact that they're out of production just makes them cheap and readily
available on the used equipment market. Info for the Data IO 29B is
available on-line. In fact, I think it's on Al's site. The Needham unit is
simple enough that it shouldn't be take more than a couple of minutes to
figure out. As far as repairs go, the only used units that I've gotten that
don't work are a couple of Pro-Log units. The Data I/O stuff seems to be
built like a tank. All the Needham and Stag stuff also works fine.

    TinkerToys are wooden sticks that you can put together with blocks and
wheels with holes in them at various angles and make simple projects. Very
suitable for 4 year olds.

    Well I know I'm a lot more selective about my TV and movies than the
majority of people but are you trying to tell me that there's NOTHING worth
watching on TV or movies? What do you have against women, beer and sports?
You also overlooked the rest of the list or do you have something against
all of them too?

   So do I but as I pointed out I have plenty of things to hold my interest
instead of designing and building $20 appliances.

    If you spend as much time, money and energy on a Microwave oven (or an
EPROM programmer) as you would, say, a PDP-8 then something is seriously
wrong IMO.
