HP-75 I/O Utilities Magnetic Card/ROM needed

Serhiy
 

Hi, new member here, hopefully future owner of HP-75C (AT&T version with HP-82718A expansion pod), I plan to use 75C as HP-IL controller to some old lab equipment (Ludlum 2200-12) and from what I'm reading I would need minimum a HP-75 I/O Utilities Magnetic Card, ideally I/O ROM, and while both are listed on eBay, I would like to find cheaper solution :)
Maybe someone can sell me copy of I/O Utilities?(email me). Shipping to US or Ukraine, payment via PayPal.

Hello and Welcome! I have lots of 75 items, these among them. But I thought you could get them for FREE somehow... transferring to a mag card may not be trivial though.
If you really want to purchase, I can probably send for shipping.

The I/O utilities are described in the manual "HP75 User's Library Solutions: I/O Utilities" which is stored in the http://www.hpmuseum.net as file 00075-90122_75_IOUtilities_UsersLibrarySolutions_29pages.pdf

The LEX file itself is at http://www.series80.org/Misc/HPILCMD.SWP

And here is the text of a posting I made in the user's forum of http://www.hpmuseum.org many years ago:

-------------------------

The SENDIO command is included in the HPILCMD LIF supplied with the HP-75 I/O Utilities.

http://www.series80.org/Misc/HPILCMD.SWP

The file in HP LIFUTIL format (DFS to LIF file type preserved xfer type).

You can get the LIFUTIL binary from ftp://ftp.hpmuseum.org/lif/lifutil

If you run into trouble the easiest way to remove the header is to copy the file skipping the first 0x200 (512) bytes. i.e.

dd if=HPILCMD.SWP of=HPILCMD bs=256 skip=2
And then you have to restore the directory info:

HPILCMD -8055 5 256 18

-------------------------
The problem is that even with the HPILCMD on a card, developing programs for the 75 will be a pain. You should consider purchasing some mass storage device such as the PIL-Box (a modern device which connects a PC with the HP-IL bus creating virtual printers and diskettes drives). Once you have that, you can easily transfer the HPILCMD to the 75, rather than requiring a magnetic card.

Thank you all for replies and help, 
Vassilis, yes, I'm thinking about buying PIL-Box, I also recently bought Portable Plus so it would be really useful tool to have :) I was also thinking that I may try using PP as edisc to HP75 and transfering code from it, if I could actually transfer it via terminal from PC to PP.

Well, there is a way to use the Portable Plus as a HP-IL mass storage by using Emu41p (the PP version of my Emu41).
When Emu41 is idle (light sleep), an external HP-IL controller (your HP75) can access the emu41p virtual drive. And there is a file transfer (x-modem protocol) built into Emu41p to  load an image file from PC for the virtual drive.
A bit complicate and probably not very efficient, it should work but I didn't test it.

Can you give more details about your Ludlum 2200-12 lab equipment? I assume it is using HP-IL since you are trying to use the PP or the HP75 to drive it.
We are a few here very interested by special HP-IL equipments.

Interesting!
Thanks for the pictures and the manuals. There are even program examples for the 41C.

The Ludlum 2200-12 has an ID$="LMI2200-12" and an AID=7Eh (general analytical or scientific instrument).
So it is not based on the 82166 components but is using a dedicated HP-IL firmware.

Yeah, it was nice of them to include examples, unfortunately now 41C + HP-IL module + I/O ROM = Small fortune... 
To put it in perspective, I got Ludlum 2200-12 for $40, Portable Plus - $60, 75C - $150

Have you considered using a 71B as a controller?

  • Smaller
  • Faster
  • More memory capability (PP EDISK not needed)
  • More support in the online community

Dave

Serhiy
 

Yes, but it is more expensive + I would most likely need to buy HP-IL module, so like $300 total? :(

While the HP-75 would be my preference as well, have you considered using the Portable Plus as controller?

Oh yes! Just today I received EPROM programmer and my PP became a little more capable, fun weekend ahead :)
First I'll try using emu41, but my ultimate goal write something native to control HP-IL on PP.
And BIG thanks goes to J-F Garnier for providing ROMs, manuals and helping with HP-IL!

If you're going to delve into the Portable PLUS, you can find the entire Portable Paper here,

Thanks, I'll check it out

Serhiy,
good that you got one of the later machines with the "green" Screen. The earlier ones have a more gray LCD which is even harder to read.
Looking into your ROM drawer I see that there is a SERIES/100 BASIC ROM.
I believe this is not yet archived as a ROM Image on the web. Do you have the equipment to read the contents of this EPROM and save it as an image file so that others could burn an EPROM copy?

Serhiy
 

I actually was thinking about it, but wasn't sure if there's any copy protection or something like it

P.S. I used XGecu TL866II Plus to program chips, I think it will read original EPROM as well. I'll try anyway.

Serhiy,
there is no copy protection and it should be easy to read the EPROM.

You only have to find out which EPROM type it is - probably a 27C256 or 27C128.
All you want to know about making EPROMS is on Jean-Francois' fantastic web site.

Hi Martin,

The Series 100 BASIC ROM image, manual, and QRG are available at the HP Computer Museum, here,
http://www.hpmuseum.net/display_item.php?sw=587

Hmmm, it appears Jon forgot the QRG.  Here's everything.

Additionaly, the EPROM's a 27C256.
