Hi, I had similar  problems so l bought a drive off ebay. CD/DVD drives are widely available and are not expensive, I got mine for £9.99 free p+p.

Hi All,
Windows 98 as far as I can remember came in two parts one floppy disk and one CD.
The floppy was the startup disk.
I think the later versions Windows 98SE may just have been on CD.
The startup disk and the ISO are available on the net.
I understand that there is a floppy disk version on Windows 98 which is/was available from MS but was 39 Disks.
There seem to be plenty of second hand internal IDE CD readers on various websites.
Best of luck,

Keith

I had great difficulty in finding the floppy version of Windows 98, the solution I went with was piggybacking an internal CD ROM drive set to slave on the same IDE cable as the hard drive and installing that way. 

Another problem I ran into was the minimum system requirements. RAM was easy (just buy some) but with the CPU I had to override the CPU check with commands:

I downloaded Win95 and 98 from the internet, I can't remember what was required to install them. I think there was a setup.exe file, I don't think I had to create an iso image.

Frankly said I have not followed the whole discussion here, just wanted to throw in that there are diskette drive emulators that convert a floppy drive interface into a usb port. If you get it working at all that might add some comfort.

I remember installing Windows 95 from a whole bunch of floppy disks back in the day but I don't know if there is still some software available that will create all those floppy disk images from a cd image as there used to be. You may want to find out if you have enough floppy disks, I don't remember exactly how many it took.

I would add two other possiblities to the above list: Install a usb add-on card or an internal cd-rom drive, if the machine has a possibility for either of them they might be easier options. Maybe you could also hook the cd-rom up only temporarily with the machine open for installation. If the machine is pre-usb it should have an ide hard drive interface and to that you should be able to hook up 2 devices per channel normally.

No usb on this machine. 

I have the CF Card Adapter, but imaging the iso didn’t work. 

May have to try the partitioning. I don’t have a boot disk (yet) 

Thanks for the input

1. USB could work if available. Maybe need to boot from floppy.
2. Try a CompactFlash card (has the same pinout as ide, only smaller, adapters are cheap) as a harddrive and fill it with the windows setup
3. Try a SD IDE adapter
4, Connect the harddisk to a modern pc with a USB ide adapter, partition the drive and copy the windows setup to a second partition. Still have to boot from a floppy I think

Hi Ron,
Most of the C5 lathes seem to have tape drives.
There is at least one C5 on YouTube with a floppy fitted but that doesn't help a lot.
I have looked on most of the forums and YouTube but there seems to be a shortage of information on the disk drive.
I would love to see the schematic of the interface card but there does not seem to be one about.
As there is a possibility that the interface is an OEM product I have been scouring the internet but have not found anything.
I'm sure that something will turn one day but in the meantime I have a very dead floppy drive.

I have been following this email chain, I have a T2 control on a VMC100 with a floppy drive.  It has never worked and I am curious if this is a similar system to what you have.  
I ended up taking a microtape drive unit from a backup t2 control I had and have been running that.  I really don't care much for the tapes though and I only have 3 of them.  
I will say I was able to plug the tape drive in and it worked right away.  With that said I also installed the CPU board from the old T2 I got the tape drive from as the main CPU has some bad interface circuits.  Changing both items may be why it worked so easily.  

I do recall the original CPU did say Disk for saving and am pretty sure it now lists tape, but I would need to confirm.  I am not sure if there is an eprom change other than the "Disk/Tape" change.  

I would like to revisit the Disk unit depending on your results.  I will continue to follow and will locate the disk and controller drive this weekend to confirm some of the information on the unit I have.

VMC-100 central lubrication intervals

atlantis@...
 

Hi

I am currently retrofitting my VMC-100, it is a slow process but I think I'm getting there.

For the Willy Vogel central lubrication my plan is to turn it into a time-interval lubrication. I'm sure that LinuxCNC can do the same travel-based lubrication that the M2 control does (add up the travel on the guides and turn the pump on for 8 s after every 20 m) but I can still dive into that later if necessary, for the moment I try to keep the fancy programming to a minimum. I have also added a level control that starts beeping if the oil level in the reservoir goes too low, basically every other machine I know does that anyway.

The only thing I wonder is what interval might be appropriate. Has anyone else done it this way and what intervals are you using?

Regards
Martin

Hi JG,
I have uploaded some photos of the Floppy drive and interface card as an album.
The Interface board is marked DE115/2
The Eprom has the following numbers and letters EMCO EXDI or 1 P28311155 /2.32
The board has a label with (3)? 2665 V2.0 WA85094.
The Disc ( disk) drive is a TEAC FD235HF.
The disk drive looks standard but there is a fine wire added which can be seen in the photos.

As you say this interface is probably manufactured by someone other than Emco and then fitted with an Emco EPROM.
I am still looking round the internet to see if I can find anything.
The black electrolytic capacitor is the 16 Volt rail.
There is a small black block marked PJ220 next to this cap and a 4.7 volt Zener diode just in front of the power transistor.
The large blue electrolytic is the 5Volt rail which does not appear.
I will keep on investigating.

Keith

Hi Dieter,
The electrolytic capacitors have been checked with several instruments and both are OK and hold a charge.
The blue one can be taken out of circuit with the link next to it.
I do have a desoldering iron but decided not to remove the caps as they test OK.
I don't have another photo at the moment but here is a brighter version of the original.
I am still convinced that someone has been playing about with this interface before I bought the lathe.
The row of links can be seen at the top left of the picture there is a brass link fitted but it is turned round so it does not currently do anything.

Hi Keith,

Very difficult to see details on the picture, the resolution is to bad.
You can send me a better and brighter picture with the highest resolution, look in the address book.

Look also at the cap's like "J G" did or replace them immediately, perhaps one fails,
of course if you have a good "desolder iron".

Dieter


Re: 3.5 inch floppy drive controller

Hi Dieter,
Thanks for your message.
Unfortunately I have not had any replies from anyone with a C5 with floppy drive.
There are three DIP header links on the board.(green)
2 have no links connected the third has a link, at the side of the large blue capacitor.
There is a strip of links (coloured green in the photo I posted above.
No links are fitted in this block.
It may all be correct but as the back was off the lathe when I bought it I don't know its history.
If anyone does have a C5 with a floppy I would be grateful if they could see how it is connected.

Keith


Re: 3.5 inch floppy drive controller

Hi Keith,

-There is a strip of links on the PCB but nothing is linked, this may be correct or links could be missing.

If there were links missing one must see burned or scratch traces.

Ask for pictures from the board to compare with your board from an owner of a disk equipped C5.

Dieter


Re: 3.5 inch floppy drive controller

Hi All,
The 5 Volt rail would appear to be the problem.
There is a link on the PCB to all the components that run on 5V.
I decided to open the link and provide a 5 volt supply from a separate PSU.
The drive then senses a disc and opens the cover on the floppy.
I no longer get the error codes but the drive does not load or save programmes or erase discs.
Trying to draw out part of the circuit but its very tiny and difficult to see.
I currently suspect that the 5 volt rail should only be turned on when some action is required.
Further investigations later today.
There is a strip of links on the PCB but nothing is linked, this may be correct or links could be missing.
A schematic must be out there somewhere.
