this is just way too groovy. As soon as I get the kit
from BGMicro to iron out my own circuit boards (and
they're currently out of stock), I'm going to try my
hand at etching the board for the 80188 robot brain
board. The only foreseeable kink is the need to drill
the holes before etching but after developing or
whatever. Standard drill bits have a tendency to tear
up the lans if you do it afterwards (although I
believe you can lessen this by grinding the bits at a
different angle, like I'm going to do that anytime
soon. Maybe you can buy drill bits ready for this sort
of app?). I actually have a small CNC milling machine,
but it's not yet ready for prime time. Problems
problems...
Vesta freely gave me the rom images for the FORTH
interpreter and the BASIC/BIOS (the picture of the
finished board shows a BASIC and a BIOS chip - will
have to make further inquiries about that). Doesn't
mean they won't mind if it's distributed, but they
thought I was inquiring because I wanted to use the
thing for some constructive purpose. And recommended
some of their newer products. I'll have to shoot them
a note myself...
And I guess it was dopey to ask if there was a fdc.
You had already said it was primarily ttl. okey dokey
:D
I haven't bought anything from BG in a long time.
"That" woman who often comes to the phone - ain't she
just the sweetest l'il ol' thang LOL LOL. You'd figure
after being in business for as long as they have,
you'd get barked at once in a while.
