The .MEM files are identical in format to the files produced by J-F Garnier's ROM dump program which can be found in the Emu71/Win manual and J-F's Emu71/DOS manual. These files conform to the TEXT Data File format described on p.247 of the 71 Owner's Manual which is why the READ command can be used.

To convert binary ROM images to the MEM format the ROM2DMP program in Christoph's FILETOOL package can be used which is how I converted the Diag ROM image. The line numbers will need to be stripped off.

Given that, the easiest way to load ROM's into the 71B is to ROMCOPY the binary images from a LIF disc or image. The HC ROM's will need to be loaded by Paul's program. Speed is also a factor. To load an ASCII image takes about 17 minutes for a 32k ROM or about 45 seconds to load the binary image using ROMCOPY.

Thanks to Paul for these excellent programs. The one for listing the memory buffers is especially useful.

When I look at the MEM files, that came with the package of ROM images made available here recently, with a HEX editor on my PC I see that they are strings of 64 ASCII characters followed by 0x0d (CR) 0x0A (LF), when I create a TEXT file on a 71B, such as using transform to convert a BASIC program to TEXT the file it creates has variable length records each one starting with a byte of 00 followed by a 1 byte length and no CR LF at the end of a record. If you take the DOS text format file and copy it over without transforming it to LIF1 format, even if you get the correct file type set in the LIF directory, the READ command on the 71B is going to have a hard time understanding the file.

Per the previously referenced page in the 71 Owner's Manual, TEXT files "are formatted to be read by other Hewlett-Packard computers, such as the HP-75", which would imply they are LIF1.

So don't do that. I use HPDir to copy DOS text files to/from LIF images with the -c option to perform the conversion. I also use HPDir to copy binary files to/from LIF images (see Post #2). You can experiment with this technique without a PIL-Box by using Emu71 and ILPer.

..and I don't as I mentioned in post #100 I use HP lifutil to convert the files from DOS text format to LIF1 and write them onto LIF format diskettes which suits me fine. In you post #101 you implied that the MEM / DMP files as distributed, conform to TEXT files as documented in the 71B manuals however the manual reference you quoted only mentions the existence of TEXT files and does not go into details about the layout of records in the file, but I know from my experience DOS text files are not the same 71B TEXT files and conversion is required. I determined what the difference is by my own investigation, largely by examining hex dumps of both file formats.

My point in stating " The .MEM files as distributed are DOS text files ie the records are terminated with a CRLF sequence which is not compatible with the 71B's idea of a text file ." is the MEM files that are in the ROM image package that I downloaded are all DOS format text files and there needs to be conversion done to make the files usable on a 71B.

Yeah, I misspoke. I think we agree that the MEM format files need to be converted to HP71 TEXT (LIF1) when they're copied to LIF media. If you think the files should be distributed in a different format, then I'd be interested in your suggestions.

I personally use a modified version of JFG's alifhdr to convert a DOS or UNIX style text file into a LIF1 text file with a 32byte LIF text file header ("alifhdr input_file LIF_file /T").

The resulting LIF_file then can be directly transferred with the ILDoslink device to a HP71 ("COPY :DOSLINK").

I prefer to not deal with files one at a time so I've updated the batch file from Post #2. It works as follows:
  • Binary ROM and EPROM images have the extension .bin. These files can be ROMCOPY'd from a LIF image into a 71 or mounted in Emu71.
  • Binary HC ROM files have the extension .rom. These may be mounted in Emu71 with their accompanying SC .bin file, but they will not be copied to the LIF image.
  • ASCII HC ROM files which need to be converted to LIF1 have the extension .mem
  • An empty 16Mb LIF image needs to be created. In this case it's named 16mb.lif
  • Put everything in an empty directory and execute the batch file. It requires a single arguement which is the name of the LIF image, i.e., HP71ROMS.lif.

Code:
@echo off
copy 16mb.lif %1 > nul
if exist *.bin copy *.bin *.#E21C > nul
echo.
FOR %%f IN (*.#E21C) DO (
    echo %%~nf :
    HPDir -add %1 %%f
    echo.
    IF %%~zf == 16384 HPDir -attrib -aux 800100800000 %1 %%~nf
    IF %%~zf == 32768 HPDir -attrib -aux 800100000100 %1 %%~nf
    IF %%~zf == 49152 HPDir -attrib -aux 800100800100 %1 %%~nf
    IF %%~zf == 65536 HPDir -attrib -aux 800100000200 %1 %%~nf
)
DEL *.#E21C
FOR %%f IN (*.mem) DO (
    echo %%~nf :
    copy %%f %%~nf.txt> nul
    HPDir -add -c %1 %%~nf.txt
    del %%~nf.txt
)

This creates a LIF image with all the binary ROM images, which can be loaded with ROMCOPY, and all the HC ROM images in 71B TEXT format.

Then all that's needed is to mount the one LIF image in ILPer. Like this: HP71ROMS.lif Here's the contents:

RE: [FRAM71] Pre-Production Batch
Dave, thank you for your effort in this and Hans, thank you this great product FRAM71.
And thanks all for this beautiful ROM's!!

Yesterday I was able to load the "HP41 Translator ROM" in my real HP71 with FRAM71. (To fill up
the $E0000 area is a little bit tricky..)

But, so much fun!!!

With my Arduino IL drive, it needs only 18 seconds to load a 32k ROM(!)
(with romcopy)

Best regards
Tobie

Thanks, Hans.

In an email you stated, "There is no longer the restriction to have Chip_0 assigned to F_Block3 when configuring it to E0000. Chip_0 may now be configured to any F_Block0…F." The manual still poses a restriction.

Could you give us a brief update on the project's status?
  • Number of units in the field
  • Plans for another production run
  • Future firmware/hardware updates
  • When will the design files be released? Some of us are interested in 3D-printing custom bezels.

RE: [FRAM71] Pre-Production Batch
ow. good catch. manual changed accordingly by yours truly, see post #1.

it requires at least 30 or more seriously(!) interested pre-orders to economically justify another production run. so, there are no plans to do that until there are enough people banging at my door.

one more firmware spin is in planning to add a feature that i personally would really like to have on my FRAM71. however, i want to analyze the feasibility first before i disclose anything about that V600.

i'm not planning to do a hardware re-spin, as this would imply a somehow evolutionary step in terms of new features and consequently require specialized driver-support on the HP-71B side of things. take as an example the (still) experimental UART in FRAM71, where the response to my support request for writing a suitable driver in assembly was zilch- so, my understanding from that response (or the lack thereof) is that the assembly language legacy for a vintage platform like the HP-71B is practically no longer existent and hence renders such project ideas basically stillborn, imho.

as for the design files, let me meditate a little longer about this. i have a bit of a hard time (call me sentimental, if you wish) to "simply let go" the fruits of 5 years effort that brought quite an amount of b,s&t besides the obvious(!) fun.
so, bear with me for now.

I can appreciate that. I'm really only interested in the STL file for the bezel.

Thanks,

I'm seriously interested, and I hope enough people will join the queue. What's necessary to make you feel confident?

RE: [FRAM71] Pre-Production Batch
I just installed my FRAM71 module, seems to works great (at least I can use MATHROM, JPC ... I had a bare memory HP71 but with HPIL)

I just have some problem with it

I romcopied MATHROM, JPCF03 and CURVEFIT in F-blocks D, E and F.

I configured FRAM71 with
POKE "2C000", "131415961718199AABDFDEDD00000000"

So I could do FREE PORT(5) to have an IRAM of 128K (it is shown in SHOW PORT), MEM(5) gives 131067

But when I try COPY PROG TO PROG:PORT(5) it result with
ERR: Insufficient memory even with a 200 bytes program.

(if I configure the IRAM at 96K it is the same, if I freed 5.01 it is the same also)

I have a 1BBBB ver system, FRAM is with 502 firmware

I can not manage to diagnose if it is an F-RAM problem or something else ... (perhaps a misunderstanding of the manual)

No freed ports :

It works !!! I just changed the order of the iram vs roms
for port 5.00 to port 5.03 and now it works

The base address of the iram also changed from C0000 to 80000 so it avoid the E0000-FFFFF part which can be peculiar

Quite strange ...

I wanted to have an iram called PORT(5), better than PORT(5.03) but it seems impossible.

After more test I only succeed with : DFDEDD131495161718199AAB000000 this one use the full address space (hpil at 0xF0000)
Code:

RE: [FRAM71] Pre-Production Batch
congrats, olivier!
seems that after some extensive tinkering with the configuration options you finally managed to generate what i would call an "IRAM zombie": neither CLAIM PORT nor CN2:2 and MEMORY LOST brings back the FREED memory, nor is it possible to COPY anything to the affected PORT.
good news is that i could replicate the symptoms on my test rig and probably have already found the root cause. need some more time for testing before i'll be posting a V510 update.
(note that this bug only affects V5.0x firmware versions)

So it would be possible to recover the FREED memory by installing V430 firmware?

RE: [FRAM71] Pre-Production Batch
on V430, with olivier's example:

POKE "2C000", "131415961718199AABDFDEDD00000000"
So I could do FREE PORT(5) to have an IRAM of 128K (it is shown in SHOW PORT), MEM(5) gives 131067
gives the same memory value for PORT(5), and COPY PROGRAM TO :PORT(5) works as expected.

note that V430 has internally the same bug as V50x. it is due to a different handling of ID-responses and latching the address masks, that the bug will not show directly on V430. i suggest to wait for the V510 update, rather than going back to V430.
