Each set of Portfolio ROMs supports three keyboard and text languages. There were four language versions.

EFG        English, French & German
EIS          English, Italian & Spanish
ESD        English, Swedish & Danish
ESS         English, Swiss French & Swiss German

There were four official releases of the Portfolio ROMs: 1.030, 1.052, 1.072 and 1.13X. The X in 1.13X identified the languages, 1.130 was EFG, 1.131 was EIS, etc.

So 16 ROM variants in total.

EFG 1.030     EIS 1.030   ESD 1.030   ESS 1.030
Common      EIS 1.052   ESD 1.052   ESS 1.052
Common      EIS 1.072   ESD 1.072   ESS 1.072
EFG 1.130    EIS 1.131   ESD 1.132   ESS 1.133

Most of us will have EFG 1.072. It is very common. EFG 1.052 is also common.

If you have a Portfolio with a set of ROMs that is in the list above, can you share this information?

If you are interested in learning more about the ROMs in your Portfolio, I've attached a small memory dump utility, MDMP.COM. This accepts the following parameters. They are upper case with a 0 (zero) at the end:

ROMC0          - Dump of 0C0000h to 0CFFFFh
ROMD0          - Dump of 0D0000h to 0DFFFFh
ROME0          - Dump of 0E0000h to 0EFFFFh
ROMF0          - Dump of 0F0000h to 0FFFFFh

e.g. MDMP ROMF0 will dump the top 64 KB into a file called ROMF0.

This allows you to dump the entire 256 KB of the ROM in 4 parts, to make it easier to transfer.

Plus it can dump an Expansion ROM, if anyone has a peripheral with one in it.
EXPC0      - The first 64 KB of any expansion ROM

It can also dump a memory card if you are interested:
CCMC0      - The first 64 KB of the card A:

MDMP.COM makes some Int 61h calls, and may not work on a normal PC. If you get a “Disk is full” error, the image will be partially created. A valid image is always 65536 bytes long.

Have you or someone else deleted the ROM dump, which where uploaded?

I uploaded some ROM images, but noticed that  Atari still owns the Intellectual Property: https://docs.google.com/presentation/d/1e-tl9Oqwnr78879Lnne_uhlsGkPWFK_z428ZmUaJjog/edit?pli=1#slide=id.g2ff92e3406f_0

Even after all this time Atari might have a concern. So I removed the images. I’ve asked Atari's Legal Dept to clarify their position.

I don't understand. What do you mean by "share this information"?

By the way: Nice to see you again here, David.

While there are many Portfolios with EFG 1.072 or 1.052 ROMs, the other variants are not so common. You rarely see them mentioned in online posts.

When I said "share this information", I am asking anyone who has a different ROM version to reply to this thread. Especially if they have a non-EFG keyboard layout.

I have only EFG, Version 1.052, 1.072 and 1.130

It would be great to hear from anyone who has an EIS, ESD or ESS version of the ROMs in their PoFo.

Correction: Each set of Portfolio ROMs supports three keyboard and text languages. There were four language versions.

EFG        English, French & German
EIS          English, Italian & Spanish
ESD        English, Swedish & Danish
ESS         English, Swiss French & Swiss German

There were four official releases of the Portfolio ROMs: 1.030, 1.052, 1.07X and 1.13X. The X identified the language variant.

From memory, versions 1.030 (a very limited production run) and 1.052 were EFG only. The next two ROM releases were:

EFG 1.072    EIS 1.073   ESD 1.074   ESS 1.075
EFG 1.130    EIS 1.131   ESD 1.132   ESS 1.133

Most of us will have EFG 1.072. It is very common. EFG 1.052 is also common.

If you have a Portfolio with a set of non-EFG ROMs that is in the list above, can you post some details?

Hi Karl,

I sent you a message asking if you could create ROM dumps for your 1.130 Portfolio, and send them to me. But I should have explained why.

I’m creating a small utility that can be used to delay a power down. This can be used within a CF device driver, so that if a power down request occurs in the middle of a disk read or write operation, it is marked as pending, and only after the disk operation has completed will the power down occur. This should prevent a power down from causing disk corruption.

To do this, I need to look at stack and address offsets in disassembled ROM listings. I’ve done this for 1.030, 1.052 and 1.17X ROMs. But don’t have a copy of the 1.13X ROMs.

Can you help me please? I will share the utilities and their source code on the forum.

Kind regards,
David.

Hi David,

I also have an EFG with 1.130, but have look first in the cabinet, if it still works.

Cheers,
Robert
