- I just joined the group. I posted once in the old message boards and
I am hoping to be more active here. I actually have never seen a
real ELF in person, but I really enjoy using the emulator. I have
been using it and a few other old computer emulators to teach me more
about programming and assembly language.
- Hello All,
I recently discovered this group and it gave me the urge to dig out
my old ELF II, or more precisely, to retrieve it from the attic of
my parents garage.
I built it during the summer of 1980, between my 8th grade and
freshman year. I added the Giant board that winter and over the
next year or so added the color/sound board, 4k RAM, and ascii
keyboard. A year or so later I added the Netronics Video Terminal
and the Full Basic/Math coprocessor board.
So far I've got the main board, giant board and color/sound board
working. I thought the 4K RAM board was working but soon discovered
that bit 5 of the 1K bank from 0x400 to 0x7FF is stuck high. So the
hunt for a few 2102 chips has begun.
Much to my suprise I've been able to recover the old tapes that I've
tried so far, in fact I discovered the problem with the ram when I
couldn't get "Animal Races" to execute after loading it.
Once I get the ram fixed I'll try my Tiny Basic tape.
I haven't attempted to recover the Full Basic board yet because I
recall that I accidentally overwrote one of the eproms while
modifying the board to allow me to use it as an eprom programmer.
I plan to restore the board to it's original state before attempting
to us it. If anyone has a copy of the Netronics Full Basic code I
would like to hear from you.
I also need to checkout the ascii keyboard / terminal, maybe I'll
find the time in the next week or so.
In relation to a few posts regarding the 1861 and more modern TV's,
I also had to feed my video through a VCR to get it to work.
I spent a LOT of time on the ELF back in the day and it's been a
real blast getting it up and running again.
