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...
Hi everyone, I've been very interested in the Elf computers for years now. I've dabbled some with 1802 programming using emulators. It's hard to find a 1802...
... Good start, but I understand wanting to run the real hardware. ... I have both, and for me, they do different things. I started with a Quest Elf (switches...
I would definately build "Spare Time Gizmos" ELF-2000. $20 for the blank board (Which is a very high quality board and an excellent design). You can make a...
First I'd like to say thanks for the fast replies, their rich content and the pleasant tone - I'm not used to this in internet forums. Now onto the technical...
Hi Poe, ... webpage? It's on page 130 of the "User's Manual" where the schematics are. STG offers all the User's manuals and schematics of ALL the ELF2000 and ...
Hi poe, So what design are you going to build? Your own, the ELF2000 or the origianl ELF? -Tony (CO)mplementary (S)ilicon (M)et(A)l oxide (C)onductor ... ...
... Tony, Not sure yet. The elf2000 seems to be a very "modern" machine and something that I'd probably spend alot of time with. The original is fun in the...
Wow, this is wierd, I just finished building the DISK/UART/RTC board for the ELF2000. Wow it worked great!! I checked SHOW DATIME and it recognized the RTC ...
Yep!! It was a bad Dallas DS12887A chip. I called Digikey, and told them the Dallas chip died and they sent me a new one within a few days. It was a $9 chip so...
Hey all, I'm primarily a lurker here on this group. I recently was cleaning out a storage area and came across my Elf collection. I thought I'd list the...
Computer Builders, I suppose the sane way to make a qwerty keyboard for an Elf is to start with an inexpensive PC keyboard. Maybe strip out the electronics...
Hey Dan, Thanks for the heads up about your ELF documents and experience. It seems a little quiet on the board these days but maybe you'll stir up some...
This was a little project I did to interface a PS/2 keyboard to vintage computers. http://www.tinymicros.com/wiki/KeyMapper Unfortunately, after the prototype...
Neat idea... After seeing various laptop xboxes, Atari's and the like, I wondered if someone would be inspired to do the same with an 1802 based compute. If it...
the blue hat thing is certainly fugly but I can see the attraction. have you looked inside one to see what the lcd itself is and how the keyboard is handled?...
This has been going on for a few years. A chip I did at HP back in 1994 was the first single chip geometry accelerator (3D graphics engine). It had way more...
If I recall the 9845C was the same. The color display engine was a 2900 bitslice that had more power than the main processor. Or was that the other way around?...
... There's also the MSI/88, which is probably the neatest pre-made package for an 1802 "laptop". Search the old messages in this group for MSI/88 and you...
oh, that idea is still kicking around in a few heads. I received one over the winter courtesy of a board member and I'm waiting for a (hopefully) compatible...
... I think the most straightforward way to provide a keyboard (and display) is to get an old (*very* old) laptop, and use it as a serial terminal. These...
Hello, I was going through all my old parts and came across a tube of CDP1832E chips. I read an older post on this group that mentioned these are 512x8 ROM...
Robert, I am definitely interested in the CDP chips. Gary Sent via BlackBerry by AT&T ... From: "Robert L. Doerr" <rdoerr@...> Date: Mon, 19 May 2008...
... Hello Gary, I have a full tube of the chips but will need to check them out when I get home to count and see exactly how many chips are there. I would...
Thanks, Robert. I am interested in all the CDP chips. I have been collecting all the pieces and will begin building, hopefully soon. I travel too much, which...
OK, I know the editor and assembler of the ELF2000 is a very basic version that should get you through most small projects, but these problems are just...
