Older Haas memory upgrade

Another thing someone may be able to answer for me,

The usb/floppy emulator I have fitted to my
Vf0e obviously
Mimics a 1.4meg floppy disc so let’s say my memory upgrade works and I have 8 meg of memory

How would I go about loading 1 single program that was bigger than 1.4meg?

The usb thumb drives have to be formatted to 1.4meg floppy’s you work?

Not sure how you would get round that other than splitting a program into 2 and calling the second part of the program as a sub program from the end of the first

Thanks
Marc

I remember there was a hard drive / ethernet option for these machines. I have never seen one in person.
I wonder how those interfaced with the control?

I think Serial transfer is your simplest option.

Yeah my machine has a knock out on the electrical cabinet labelled ‘Ethernet’ but obviously it’s not connected to anything and I have no idea how or what that upgrade involved

I wish I could locate one of these, its the Ethernet Hard drive option

I thought I’d check the memory status before the upgrade just confirming the 2 x 512kb chips currently fitted,

Hopefully this will soon show 8192K

Still waiting on the memory chips from the supplier, hopefully have them in the next few days

14 new genuine Samsung memory chips arrived today

Nice.
I cant believe the timing of this. I Just started a project that has a lot of
big files. Just had to split 2 files in half, run them consecutively.
The file is around 1.7K.

Ok so update is i have removed the board and given it to a specialist to solder in the new chips

This is not my normal repair guy as he is just too busy for such a small paying job for the forseable future

They said its their own policy the battery MUST be removed as they wont work on it with it installed which is fair enough so this morning i done 3 seperate usb back ups of all my settings and programs and macros and parameters etc

I decided to go ahead and install all 14 extra chips at once as the price was the same whether they fitted 4 extra or all 14 and the price is the same whether they have to remove 4 or 14 again so thought what the heck

The issues they said to be aware of is how the board finds and locates its memory, so he said if the board was initially designed to use whatever is in the empty places and only checks if it is present or not then it should work fine. BUT if the board was designed specifically to only ever access and use the two 512k 8 bit chips fitted at the factory then 1 of 2 things can happen,

1 - it will just not see the memory and not use it, which is no drama just £250 wasted on parts and labour to try it to find it did not work.

2 - Having the extra memory crashes it on boot up as it doesnt know what to do with it and gets confused which im hoping is not the case but in which case i will have to pay another £100 to have the 14 extra memory chips removed again.


With all the seasrching i have done on the net for hours and hours i have found people say the chips do need to be addressed and i have found people say they do not need to be addressed, the thing is people have done it without but no one who actually made these boards or programmed them from new has confirmed the address etc is required so i am 50/50 if this will work or not

Im just hoping whatever happens that worst case i can remove the chips, re fit the board, re load all my parameters from my back up and be running again

Will find out next week i guess

Thanks
Marc

Ok so i now own an 8 MEG memory haas VF0E

That is Awesome, Good Job Sir
How did it come back up? Were parameters and settings intact? Option codes?

i video'd the whole procedure for my youtube channel

But in short....NO

As the battery was removed it lost everything, model number, serial number, parameters, settings etc but all in it took me about an hour to refit the board and figure out how to re initialise etc with your info and a little bit of extra head scratching as some things didnt go as per procedure

But it worked and once i have edited the footage and video i will upload it for everybody to see etc

Thanks for all your help

Hi

The video of the upgrade and the boot is now live so I though I’d start a clean thread for it

Thanks for all the help

My successful Haas memory upgrade 1mb to 8mb YouTube video is up

Hey Marc, I finally had a reason to open her up, I did the Dual Backup battery Kit install.
While in there I snapped a few picks of my memory modules. I found and purchased 6 of them.
One thing I'm curious about is the capacitors. It seems each module has an associated cap.

And the last one

Hi Roamer

Not sure on the associated caps, I just filled the empty places and hoped for the best and it worked lol

It looks like you have them already.
In my searching, it appears sometime around 01-03 they stopped filling the board, and only added
the caps where there are mem modules. Not a big deal, if I go this route, I'll desolder one and measure it.
In your third pic, the one where it shows the words Battery Backup, you can see the caps are present even tho no module is there. On my board, they are missing.
