Elf 2000 Firmware #ELF2K

Rob Carnegie
 

I just noticed that the link to the firmware on the Spare Time Gizmos website (http://www.sparetimegizmos.com/Hardware/Elf2K.htm)  is coming up 404.  Does anybody know where I can find a copy of the most recent firmware for the 22V10 and the ROM?

That looks really nice, constantly amazed at what people can fit on a single PCB. Think mine came in at twice the size.

I have got to look into a few of those displays before they completely disappear, they've got such a unique look to them. IN-button bottom right, or one of those that flips back?

In a side-note, is there a resource available somewhere that explains I/O? Not sure of the correct way of adding stuff to it, using address space like on 6502 was my first idea though might just be me being more familiar with those.

Hi,

Being a vintage computer collector, having failed to purchase a Cosmac Elf, I decided to build my Own. Here it is running the equivalent of the “hello world” program: turning on the Q pin.

 

Cheers.

Looks like a clean little build. Congratulations!

Hi there,

Today I released a new version of Emma 02, V1.32.

Main additions are the CDP18S600, CDP18S601 and CDP18S603A Microboard emulators.

For the full list of changes have a look at the changelog.
Downloads are available for Windows 32/64 bit, OS X and Linux deb/rpm.

I intend to add CDP18S604B in the next release and would love to add the CDS systems but to do so I will need images of ROMs and disks. So if anyone has those please drop me an email....

Cheers, Marcel.

Yes, I do have an Apple iic, drives, monitors, etc. but so far I haven't found the power supply for it. I probably checked it out a year or so ago, but can't be sure.

Keeping it OT, the code dates of these chips range from the 70's to the 90's. I also have a Cubic programmer board for the Aim65.

Thanks for checking!

Marvin

Hello!
We are drifting just slightly here, but.... Is there an Apple IIC in
that collection?

I am not familiar with quite a number of these chips. Here are a few I have "in my hand" :).

21 0 AN99CK641 64K x 1 Static RAM
4 HM6168H 4K x 4 bit high Speed CMOS Static RAM, marked "SAMPLE"
1 or 2 Philips UART SCC2691

20 MCM8804AC 4K Static RAM
43 AM99C641 65K x 1 SRAM
4 AM27S49DC ENG SAMPLE
2 DL2416T Displays (Aim65, etc.)
23 SEMI 4402ACC
8 Cypress 7C517-45OC 16 x 16 Multiplier (marked as having a problem)
1 CDP1892CE
1 CDP1802ACE
1 CDP1851CE
1 CDO1854ACE
1 tube 78L05 probably around 200 or so (ordered wrong part footprint.)

Etc, etc, etc., and this is stuff I know I don't need. Right now, my emphasis is on getting a bunch of computers checked out to sell (Apples, Amigas, Commodores, Ataris, TRS-80 model IIIs, Cocos, etc., etc., etc :).

I haven't gotten into the 7400 stuff or 4000 series stuff yet, as well as the other boxes of "stuff" that I don't know what they are. I would say from what I see that almost everything is digital although there might be some analog chips spread around. There are also probably a couple hundred tubes of chips I haven't looked at much.

Jason hasn't really assigned the selling spots yet as they are still subject to change,so no real idea where I'll be. I'll be driving out leaving either Monday or Tuesday morning early to arrive on Thursday afternoon.

Hope this helps. Makes me tired just thinking about this stuff :).

Hi Marvin,

Do you have any 4801 Dynamic RAM chips?  Sounds like we're playing a game of FISH.

Looking forward to meeting you at VCF-MW.  I'll be with Lee at the 1802 Table.

Cheers,
Josh

Brian,

 

Just checking in:

   A) in case I’ve missed something or my outbound ‘off list’ email failed to send,

   B) curious if you might have gotten work schedule under control…

 

Absolutely not pestering – I have several home projects which also take a backseat to real work schedules, so I get it.

 

Just curious if I have in any way missed the boat for the 2 cards I think I signed up to and my support of the idea of a consolidated parts order.

 

Be well,

 

Steve

Sorry, my work schedule changed unexpectedly. My plan is to order 20 of the boards which will result in a cost of $6.50 per board to each buyer, plus USPS Priority Mail shipping costs in a padded envelope with cardboard stiffeners at $7.50 for a total of $14.00 per board (I'll combine shipping for those interested in more than 1). If any additional people are interested, I'm going to keep the group buy open until next weekend. So far approximately 10 to 12 boards of interest which will leave me some additional ones for future buyers. Boards will include the most recent revisions that I have access to. Shipping time will probably be about 2 to 3 weeks from the time of the order.

Anyone that has not already expressed interest is welcome to comment here or send a private email.

Regards, Brian.

The PS is just rectifiers and filters to get +16,-16, +8 unregulated.
All regulation is local so unregulated voltages are all that's needed.
Mine actually has a PowerOne unregulated supply that did exactly that
as I didn't buy theirs.  Those were common in the 1977-1980 time
frame.

Yes..I have all the digital files for the aexplorer/85...actually planning to expand it at least to fill-up the board ( roms and rams) but have not source the parts yet... i am missing the original  PSU for it too..thnx

Look around for the B,C,D,E manual they are on the 'net.  Also the hex images of
the Basic in eprom (2716 size x4).  (netronics Explorer 85).

I have mine fully blown out with a JAWS 64K board and a serial IO card for stuff
and the classic Processor Tech VDM64 (16 lines by 64 characters) NS* MDS
board for floppy disk.

Fun box and S100 too.

An 8085 membership card would be along the lines of a Z80 one save for it cannot
run a lot of the Z80 programs that are not generic coded (limited to 8080 instructions).
That leaves a lot of good code there for playing.

I have the Netronics Explorer/85 but is only at Level A ( plus the Ascii keyboard). Now (thanks to the post), I have an alternative to build one farther than my 30-oddsome years old 8085 system.

Thanks Rob...will see you at the club. I ordered too several crystals that I can not seem to get locally ...mostly in DIP8 package...like that on Elf2K. I can probably order them tru Mouser or Digikey but they have min. order or shipping is too much ( for me anyway)...
