ERAMCO MLDL @ Ebay Message #1 Posted by Jean on 22 June 2004, 1:13 p.m. there is one of the greatest HP41CX items at ebay a ERAMCO MLDL ! http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&category=9972&item=3822984441&rd=1&ssPageName=WD2V

Re: ERAMCO MLDL @ Ebay Message #2 Posted by Ronald on 22 June 2004, 2:40 p.m., in response to message #1 by Jean Hi, Is this really special and rare in other words as collector a "must have item" ? or does it appear more often on Ebay, in this forum ? Ronald

Re: ERAMCO MLDL @ Ebay Message #3 Posted by Jean on 23 June 2004, 2:52 a.m., in response to message #2 by Ronald it is absolutely rare. the last I saw about 2 years ago. it is a must-have for machine code users and for collectors. it is maybe the first MLDL (machine language development lab) that has been issued for HP-41C.

Re: ERAMCO MLDL @ Ebay Message #4 Posted by Massimo (Italy) on 23 June 2004, 4:50 a.m., in response to message #3 by Jean Not anymore. May I suggest Clonix and NoVRAM modules from Diego? I have both and find them invaluable: they are compact and powerful. Yes, I own an Eramco MLDL too... Massimo

Re: ERAMCO MLDL @ Ebay Message #5 Posted by Ronald on 23 June 2004, 6:06 a.m., in response to message #4 by Massimo (Italy) It still keeps me amazing how much was invented on the HP41 and how long develolopment continues even after HP made them a long long time ago obsolete from a production perspective. For me Eramco and MDDL was something from the past, collecting dust in my memory.

Re: ERAMCO MLDL @ Ebay Message #6 Posted by Meindert Kuipers on 23 June 2004, 2:00 p.m., in response to message #4 by Massimo (Italy) And do not forget my MLDL2000 (last bug just fixed). And I do have the Eramco MLDL, a smaller rombox and the W&W Rambox in my collection. Meindert

Re: ERAMCO MLDL @ Ebay Message #7 Posted by Matthias on 23 June 2004, 6:48 p.m., in response to message #6 by Meindert Kuipers Have a look at my homepage and you can see als available alternatives to the ERAMCO MLDL. www.hp-collection.org/41accessories.html

Re: ERAMCO MLDL @ Ebay Message #8 Posted by David Smith on 23 June 2004, 11:10 a.m., in response to message #3 by Jean Actually not all that rare. They seem to appear every few months.

Re: ERAMCO MLDL @ Ebay Message #9 Posted by J.D.Clemens on 23 June 2004, 12:11 p.m., in response to message #8 by David Smith where do they appear??? I have a search tool also for them on ebay but they do NOT appear ? I never have seen one for one year that I am scanning. Have you examples of last sells?

Re: ERAMCO MLDL or NoVRAM Message #10 Posted by Christoph Klug on 25 June 2004, 3:39 a.m., in response to message #9 by J.D.Clemens Hi HP41 mcode enthusiasts the new NoVRAM from Diega Diaz is the modern replacement unit for the Eramco MLDL. The NoRAM includes the HEPAX operating system plus 8KByte additionally ROM plus great 16KByte RAM. All this is housed in a standard sized HP41 plug in module shell. Last not least the price for this is absolutely fair. Really great work from Diego Diaz :-)) Regards - Christoph Klug

Re: ERAMCO MLDL & NoVRAM & MLDL2000 Message #11 Posted by Massimo (Italy) on 25 June 2004, 4:19 a.m., in response to message #10 by Christoph Klug Right! It really is wonderful. Now I shall check with Meindert for an MLDL2000... :-) Massimo

Stupid question...Re: ERAMCO MLDL & NoVRAM & MLDL2000 Message #12 Posted by Gene on 25 June 2004, 10:37 a.m., in response to message #11 by Massimo (Italy) 1) Where does one buy the programmer? How much does one of those cost? 2) The new modules from Mr. Diaz give us ? a) the HePAX rom b) 16K of ram that the HePAX functions can address, which give us the ability to 1) Copy programs to the HePAX ram, 2) Run them from there? 3) and ? c) an additional 8K of ROM space that can be programmed / loaded with rom images using the programmer mentioned above and all in one module housing? What have I missed? and where do I buy a programmer? :-) Gene

Re: Stupid question...Re: ERAMCO MLDL & NoVRAM & MLDL2000 Message #13 Posted by Massimo (Italy) on 25 June 2004, 12:22 p.m., in response to message #12 by Gene Hi Gene, please have a look at this ad and read more about it in this thread. Massimo

Re: Stupid question...Re: ERAMCO MLDL & NoVRAM & MLDL2000 Message #14 Posted by GEne on 25 June 2004, 3:03 p.m., in response to message #13 by Massimo (Italy) Thanks, but that still doesn't answer many of my questions, such as where the programmer thing is purchased. Did I have the rest of it correct? Gene

Re: Stupid question...Re: ERAMCO MLDL & NoVRAM & MLDL2000 Message #15 Posted by Raymond Del Tondo on 25 June 2004, 5:01 p.m., in response to message #14 by GEne You can purchase the programmer with the NoVRAM from Diego. At least that's what I did... Raymond Edited: 25 June 2004, 5:53 p.m.

Re: Stupid question...Re: ERAMCO MLDL & NoVRAM & MLDL2000 Message #16 Posted by Massimo (Italy) on 25 June 2004, 7:43 p.m., in response to message #14 by GEne Quote: where the programmer thing is purchased Gene, I thought the programmer was easily visible on the ad I mentioned: Quote: NoVRAM module:........... 175Euro. Clonix-41 module:........ 120Euro. Programmer-adapter set:.. 25Euro Since it comes preprogrammed you could even avoid buying it but I'd take it anyway: you could need it in order to fully reset the module to a known state. Greetings, Massimo

Re: Stupid question...Re: ERAMCO MLDL & NoVRAM & MLDL2000 Message #17 Posted by Gene on 25 June 2004, 8:13 p.m., in response to message #16 by Massimo (Italy) Thanks...guess it wasn't a stupid question, just a stupid Gene. :-) Gene

[OnTopic :] stupid Gene [Pool]. :-) Message #18 Posted by Veli-Pekka Nousiainen on 26 June 2004, 5:25 a.m., in response to message #17 by Gene Depends on your Gene Pool... (Very Protected Notebook)

Re: (not so) Stupid question...Re: ERAMCO MLDL & NoVRAM & MLDL2000 Message #19 Posted by Diego Diaz on 26 June 2004, 7:57 p.m., in response to message #12 by Gene Hi all, Please excuse me for the late reply, I didn't realized this thread turned into such questions on my project. Gene, you're right in your appreciation, but the list is not comprehensive since the NoVRAM module is intended to be a multi-purpose RAM-Box. Thus allowing to replicate whichever other RAM-Box previouly manufactured. So it can handle *any* configuration provided: a) you keep the 24K ROM and 16K RAM limits and... b) don't make any illegal config such as using modules with the same XROM nr. or exceed the number of pages a 41 system can handle. In fact I'm now working in two directions, first trying to finish the User interface programming utility to allow free user access to the remaining extra 8K ROM. (Currently I have to program them from "factory"... so speaking :-) and second, trying to build the code for a new NoVRAM-based project that will include a double extented memory module, it will require reducing the HEPAX-like RAM to 8K though. Further more, considering NoVRAM is *loaded* with non volatile RAM it'll also be possible to built a 10 pages ROM-like module. Obviously I haven't had time enough to produce all the required code for such a "huge" amount of possibilities, but I thought the HEPAX emulation is, on its onw, a very good first step for offering to the HP-41 community. Please do not hesitate in mailing me with your questions or comments. Best wishes from the Canary Islands. Diego.

Re: ERAMCO MLDL @ Ebay Message #20 Posted by Meindert Kuipers on 28 June 2004, 10:41 a.m., in response to message #1 by Jean It was sold for EUR 223

Re: ERAMCO MLDL @ Ebay Message #21 Posted by Ronald on 28 June 2004, 4:15 p.m., in response to message #20 by Meindert Kuipers How do we judge as a forum this price, Low, fair value, high ?

Re: ERAMCO MLDL @ Ebay Message #22 Posted by David Smith on 28 June 2004, 6:48 p.m., in response to message #21 by Ronald It is in the middle of the range that they seem to bring.

Re: ERAMCO MLDL @ Ebay Message #23 Posted by Ángel Martin on 29 June 2004, 2:25 a.m., in response to message #21 by Ronald As a collectible, who knows, everything is valid. As a useful device, a ripoff when compared with the NoVRAM. My 2 çents.

Re: ERAMCO MLDL @ Ebay Message #24 Posted by Massimo (Italy) on 29 June 2004, 3:14 a.m., in response to message #23 by Ángel Martin Same feelings here (see my first post in this thread). ½ ¢ from Massimo

Re: ERAMCO MLDL @ Ebay Message #25 Posted by Ronald on 29 June 2004, 6:39 a.m., in response to message #24 by Massimo (Italy) SO it is bassically collector sentiment what determines the price. On the other hand when comparing a device now 20 years old to the present NoVRAM is also comparing apples and pears. I think it was at that time absolutely a miracle to make a thing lke that as it it is today to have the NoVRAM. Both are developed by a few individuals with no large HP Labs back-up. my 1/2 cent

Exactly, since now you have alternatives in order to achieve the same result. Quote: On the other hand when comparing a device now 20 years old to the present NoVRAM is also comparing apples and pears. I think it was at that time absolutely a miracle to make a thing lke that as it it is today to have the NoVRAM. Both are developed by a few individuals with no large HP Labs back-up. Right again. My point is that you don't need to pay such inflated prices anymore if your intent is to USE the thing. But many among us are collectors and this is another story (I have an Eramco as I wrote before). You will concede that not having to carry such a bulky device is a great achievement...
