If you remember some time ago I did the piece regarding NC-100 Data Transfer process. Well I am back at it again this time with the NC-200 and well is it any easier?
Well read on.
Is there less or more logistics in the NC-200 process. Answer? yes. Since the NC-200 comes with a floppy drive instead of just a RS232 port there is no need for a computer with a serial connection. Also since Simulant uk released a gotek conversion kit for the 200 the serial port becomes even more redundant.
Since I have Fitted my NC-200 with the above mentioned kit from Simulant UK I am able to remove some of the barriers of the real floppy data transfer but there is still some issues that need to be overcome.
How On Earth do you create Floppy images?
Well this was not really a big issue I simply booted my copy of win image. Now my NC-200 has a 720k drive from Citizen (yes I believe its the same company that makes watches) a V1DC – 65B so making a 1.44MB or 2.88MB HD was utterly pointless as I knew it would not work. (since I writing about every part of the image creation is actually pretty boring I just made some images of this process below)
After hitting ok I got a blank screen just like the first image but next to it I had (untitled) next to Win Image. Not a problem I actually have experience with win Image and all I needed to do here was save the image as a .IMG File.
Problem Number 1
Now on the Amiga Gotek setup you can pretty much put the file name to whatever you want and it will still read it however I quickly found out you cannot do this with the NC-200
After spending nearly 3 hours trying to figure out why I finally got an answer mostly by fluke really. The drive can support up to 999 floppy images (that’s around 650 real 720k floppy disks)
The fix was simple and just required me to number the files in sequence i.e 001, 002 you get the drift.
Now with that done I could drop the image onto my USB stick and drop it into my NC-200. In this case I am using a 128MB usb stick just because I have one lying around.
Now moving over to the NC-200. I am happy as the gotek is reading F-F which Means Flash Floppy the latest revision of the Gotek drive firmware indicating installed the drive correctly.
Flash Floppy & Voltmeter Check
Now on the original test I came across a bunch of issues trying to transfer files from the NC-200 memory to the floppy image. Then this happened.
Time to break out the voltmeter and find out what the cells are reading and see if I can find an answer to this problem.
Bingo! setting the voltmeter to 2.0v DC I placed the probes over just one of the cells that I was using and the meter fired back a reading of 1.5v that might not seem a big issue as most cells state 1.5v DC on the packaging.
However 99% of cells are usually 1.6v to 1.62v and while most lower drain devices will be fine at 1.5v the NC-200 is not one of those.
The floppy drive or the gotek conversion like in mine eat the battery life hence why the majority of NC-200’s were powered by mains adaptors. There is even reference to this problem in the NC-200 Manual
Even in 2019 C cells are relatively expensive when you buy decent ones the NC-200 needs 5 of them so yeah it can get a bit pricey.
So with this issue sorted I put my new C cell’s and broke out the voltmeter again to quickly check them (done this ever since buying some dead pound land batteries!)
And the 5 cells together each gave a more pleasing reading of 1.644 volts DC giving a total of over 8 volts DC
Reading & Saving Files to the USB stick
Finally with the final issue out of the way I had no futher problems with the NC-200 and followed the process in the manual to complete the process of how to copy to the drive.
And sure enough this was Pleasant sight that greeted me. “Copying – Tim2”
Then the machine dropped back to my stored documents list and I now pulled out the usb stick from the gotek drive and returned to my pc.
My hopes where high now the NC-200 had clearly copied the file onto my USB stick onto the floppy image I created earlier. And sure enough I took a look at the data for the file and it had been written to (the date on the screen is not right as the date and time are not set properly on the NC-200)
Opening the image file back up in Winimage I was greeted with this
the NC-200 had behaved just like it would on the real floppy drive so now it was really looking good. and one thing left to do and that was to explore the notebook folder and see if I could get the contents to read in notepad.
Err….. those files dont have extensions so how on earth I am going to open them. well this where I needed to add the text extension.
Reading the Text File from the NC200
Once I had the file Renamed it was just a case of opening it with the default text application. Bingo!! that is exactly what I wrote on the NC200!. its a little garbled but I could easily fix that if I needed to.
The process for transferring data from the NC-200 to PC is a 5 minute job. Even though it does not seem like it reading this piece!.
So compared to the complexity needed to transfer data on the NC-100 its a pleasurable experience on this machine. This pretty much brings the NC-200 to a position where you could theoretically use this to complete work. Not bad for a machine that’s well over 20 years old now.
Of course you need to rewrite some portions of it.
So what is the future for my NC-200?. My machine has seen better day’s there is a nasty chip in the back corner. I have repaired it with Loctite.
She is an old girl now she will spend her day’s as collectable alongside my NC-100 and Tandy WP-3.
So that brings this piece to a close and as always……
