The only detail are the N characters at the last tracks, it happened again. Do you think it's a problem?

Thanks again,

Eduardo
No,this is just some blank tracks.

Many thanks to HxC Floppy Drive Emulator developers and to Skot9000 for getting it to work in HP4145B instruments. I recently installed it in our HP4145B. It works great. Your post (and boot files) made it possible. Thank you so much.

Hello Guys~~

My lab also have one HP 4145B Semiconductor Parameter Analyzer, but the Labview software which allows a user to set and
update parameters using a workstation was broken.

Can you send me the software package?

Actually I'm not good at computer .. then is there anybody can teach me how to install this software

Many thks~~

Hi all,

Thanks you very much for the work you have done here.

I recently ran into the same issue with the HP4145B. I've tried following all the steps in this thread, I have also gotten the board posted in this thread fabricated. However, I cannot get the HP4145B to boot. I first get the error M21 followed by error M19.

Is there a specific dip switch setting that needs to be done on the slim floppy emulator?

Also, the floppy drive inside this HP4145B was a Sony MP-F52W-20 (instead of -30). I am not sure if this changes anything.

Thanks!

Now just to dress it up.
Hi,

I'm installing the floppy emulator in a 4145B, can you send me the pin layout of the floppy cable on the 4145b? I would really appreciate it.

Also is there another hardware adjustments?

Thank you for your help.

You can found the gerber in a previous post. You read them with some gerber viewer to see the connections.

I'd just like to report that I was able to create an HP 4145B boot disk from the STARTUPA_HFE.zip image supplied by Jeff with the settings hints provided by EduardoLM back in 2014 on a Windows XP computer from ~2005 with an unknown FDD and controller. Since it took a few tries, here's a brief outline of the steps I took in case anyone else needs to do this (or in case I forget years from now):

1. Place a blank disk in the A: drive and format, checking the "Create an MS-DOS startup disk" box
2. Copy and extract STARTUPA_HFE.IMD to subdirectory on C:, and rename to STARTUP1.IMD (DOS filename length limits)
3. Copy and extract IMD118 to the same subdirectory.
4. Restart computer and change BIOS settings to boot first from A: drive
5. Reboot from A: drive into DOS with formatted MS-DOS disk prepared earlier.
6. CD to subdirectory created earlier on C:
7. Place tape over HD hole on disc (all I had were HD discs from ~2000) and insert into A: drive
8. Use following settings:
Drive : A
Cylinders : 83
Double-step : Off
R/W gap : Calculated
Format gap : Calculated
Format fill : E5
Full analysis : No
Interleave : BestGuess
Retries : 5
Keep bad sector: No
500 kbps -> : 500 kbps
300 kbps -> : 300 kbps
250 kbps -> : 250 kbps
9. Run IMD118 and select STARTUP1.IMD. After a few minutes, it will finish. Boot up your 4145B!

Thank you so much for this resource. When the floppy drive in the 4145B fails, I'll retrofit the HxC emulator. Now to tune up the display . . .
