I found a file entitled "Elf2k Full Release.zip" that appears to have a copy of all the associated files.  Thanks All!

Re: Elf 2000 PCB DS1210 problem #ELF2K

Hank Riley
 

Rob,

To me the final word is the datasheet and is consistent with Ed's anecdotal experience.




The datasheet wording (in #8574)is correctly quoted by Ed as saying "must be grounded."  In addition, there is also this sentence in the datasheet:   "A grounded VBAT2 pin will not activate a battery-fail warning." 

Executive summary:      :)

             Ground pin 7 in the absence of a battery #2 on that pin.

I checked pin 7 of the socket for DS1210 on my board (one of the last series produced) and it indeed seems to be unconnected to ground.  The thread is fairly old so I am wondering if this was still the final word on the subject?  Should I be connecting my DS1210 pin 7 to ground?

Regarding 1802 I/O, I put a writeup on it in my ELF Manual, which is downloadable from the COSMA ELF website.

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.

Re: Old and Obsolete Parts

Marvin Johnston
 

Did you know the 0 and 9 are right next to each other on the keyboard :). I saw that type too, and wondered what happened. Oh well, so much for typos! I was more curious what the 1851 and 1854 are.

I thought about selling them by the pound, but then I'd have to sell them at some astronomical price. I do have a box of "tailings" though with who knows what is included... certainly not the dog though/.

I'll keep my eyes open for the 4008-9. That -9 is kind of wierd as I normally would think of the parts as 90 ns in speed.

BTW, I went out into the garage to see what I could see, and it was amazing the number of computers out there! If I had a bigger vehicle (and managed my time better), I'd try and bring things like the Cado word processor, philips word processor, Intel MDS system, and Tek paper tape XY controller., At one point in time, I had somewhere around 700 systems with the idea of starting a museum. Now, I'm more interested in keeping mainly those computers,software, and peripherals that were built in Santa Barbara/Goleta/Carpinteria (Polymorphic, Lobo, Street Electronics, Pickles and Trout, Code Works, Midnight Software, CLOAD magazine, etc.)

Gregg,  I hope to get to VCF East next year... depends if I can afford it.

But, if there's anything you want from VCF MW, you can probably ask someone from the old MARCH group.
I'm not sure who's coming this year, but check with Bill Degnan, Mouse, Z.  There's a couple of other guys that often come, but I can't remember their names at the moment.  Stack Overflow!

Re: My Cosmac Elf!

joshbensadon
 

Peter,

Building your own is WAY more satisfying than buying someone elses ELF.

I don't recognize that board... did you make it yourself?  I know that sounds like a dumb question, but
"build my own" could mean making the PCB and populating it, or it could mean buying someone elses PCB and populating.
Nice touch on adding the LED's and HEX display.  I always found that having 8 LED's for 8 Switches a better match than using the HEX displays. 

In any case, well done!

PS.  Did you ever make an ELF "back in the day"?

Josh

Marvin,

I'd love to buy the CDP1892,  don't know what it is, but I'm sure I don't have one.

Oh, found the correct part number for the DRAM I'm looking for/..

Mostek MK4008P-9 or an AMI S4008-9

Perhaps I'll take some 7400 chips too?  I suggest you sell them by the pound. LoL.
