Elf/1802

Emulation


Important Notice!
It has been a long run and I hope that Elf Emulation has contributed usefully to the 1802 community, but with the increased cost of web hosting (Elf-emulation.com was only $39 a year when I started it about 20 years ago, it is now at $300 a year). Between that and I am just getting too old now to keep up with all my projects, it is time to step back from most of my work.

At this time I have turned off auto-renew on all of my domains and my web hosting account. My websites affected by this are:

These sites will go dark once the domains expire or my hosting account expires. I intend to archive these sites to my GitHub repositories so as not to allow this content to disappear forever.

All of the material from these sites as well as all my other projects can be found at my GitHub repositories

I thank you all for your support over the many years that I ran these sites.

9/22/2020 For those who got the Micro/Elf boards that I had ordered from JLCPCB, they missed the silkscreen layer with the part names. Here is a layout diagram showing what parts go where.
8/13/2020 I have received a stock of Micro/Elf boards, these are available for $1.45 each plus shipping. The Pico/Elf prototypes are still being tested, I have run out of prom chips for making a bios so am awaiting an order of proms.
8/4/2020 Since every now and then I get requests for Micro/Elf boards and having found a low price source for them, I have decided to order a stack of 50 boards. If interested in a Micro/Elf board contact me. Projected price on these boards is $1.45 per board plus shipping.
8/2/2020 New page for Pico/Elf V2 announcements has been created
7/31/2020 Been a very long time since I have done much with the 1802, but after having several requests lately for Pico/Elf V2 boards, I have decided to dust off this project and see about getting some boards made. I will try to get a Pico/Elf V2 page put together here in the next couple days to give some details about this machine and to keep you updated on this project.
