I Just got Bob's COSMAC ELF 2000!!!!
- Wow I just finished the "Spare Time Gizmos" COSMAC ELF 2000 Board.
What a great design! I've been building and designing stuff for many
years now and the 2000's design is wonderful. Very close parts
placement, very nice PC Board design and as far as the hardware,
outstanding concept design of the circuit and monitor code! Including
the STG1861 redesign! Ive never seen one so compact. I was
disappointed that Bob stop making the printed circuit, (I guess not a
great demand for the ELF/VIP video processor) and its very hard
finding a cdp1861 these days. But due to the fact Im developing a
COSMAC VIP around the 2000, I needed to get it built, so I homebrewed
the STG1861, and it works wonderful. Just like RCA's original. At
Least Bob has the 1861 built into the 2000. Bob Armstrong is an
excellent engineer!! By far!! Thanks Bob.
Not only to mention that Bobs work is great but the built in code is
wonderful too, by Mike Riley. The Basic and Forth code seems to
operate very nice too. Havent played around with it yet, only testing
it, I just finished it last weekend. But I want to order the ELFDISK
card by Spare Time soon. It seems that Mike wrote an outstanding
ELFOS that sets up a compact Flash for Disk access for the 1802. Does
anyone know what the maximum size of the compact flash is?? 128
At first I bought the ELF2000 to play around with what looked like a
nice 1802 design. Always wanted to get back into the 1802 code again,
but It looks like Im going to buy Bobs other boards and make a full
system out of this!! Nice work Bob and Mike!!!
Im Impressed!! :)
