The M240 has no 16 Bit slots like M24 did, because they were totally useless besides some Olivetti cards (Graphics card as a "u-board to connect the mainboard with the bus-converter (ISA-slot card) and memory cards). The M24 16 Bit slots were proprietary and not compatible to the AT 16 Bit standard.

Little update. I got another 512 kB SRAM card. This is formatted in a way that my Windows XP running Thinküad T60 can read/write on it. But not HP200LX and not Poqet can read it. After finding out how to format the 512 kB card in that way that it is compatible to XP again, I will try to format...

How about Europe?

Someone was able to build it from the source

Hello, I plugged it into a Win XP, 95 and 98 machine, but none of them detected it in the device and disk manager. It's possible that I formated it in the HP with that volume label.

64 kB in A: 2 MB in B: The interesting is that on the B: drive I can read POQET 2MB FAT12 in clear text, but the card has been formatted by the HP.

Hello, is there maybe a simple solution to discover the file system difference between the two cards using debug? For example to verify if it is FAT12 or FAT16 ?

Yes, I did that. I also rebooted it. I did also some test orgy with PCMCIA equipped notebooks, my Thinkpad T41 with XP then was able to detect the HP Flash card at correct size, but it wanted to format it, I refused. The SRAM cards from Poqet weren't detected at all. My working Win 9x based...

Hello, I tryed that and I verified with L 0100 1 0 1 D 0103 010A And it displays 50 4f 51 45 54-33 2e 33 POQET3.3 like expected. But when dir b: it still displays general failure error reading drive b: The 200LX still can read the 2mb card.

Hello, yes you are right, I was not using the load command before. So now I get for drive a: and b: a: 50 4f 51 45 54-33 2e 33 POQET3.3 b: 4d 53 44 4f 53-35 2e 30 MSDOS5.0 So do you think the simple solution cold be to overwrite MSDOS 5.0 with POQET3.3 and I am done? What would be the command...

How to read the same from B:? Output is: 96 04 e8 8a 60-75 03 eb

Which comands in debug would be required to read the OEM name string? Then I can compare between the 64kB card and the 2 MB card.

What don you mean? The Poquet and the 200XL do not know anything about FAT 32 (they run MS-DOS 3.30 (Poquet) and 5.0 (200LX), and my attempts to format/access the cards were just with these until now. I need to pull out one of my XP + PCMCIA notebooks and DOS/Win 9x + PCMCIA for further tests...

Next Patchday is on 14th of may.

Hello, any experts here, which know the usage of The Poquet PC? That's a MS-DOS 3.30 based palmtop, introduced in the beginning of the year 1989, so even a bit older than the well known Atari Portfolio and much older than the HP 200LX. The Poquet is quite rare, but I got a working one. Like the...

You need something to mark the bad sectors.

You should try some standard MS-DOS disks for example from Vetus. It's not necessary to use the ones from Vetus or so. Use a DOS 5 or 6.22 from there and enable EMM386.exe and smartdrv.exe from c:\dos directory. On that machine nothing special that it would need special Olivetti versions.

6.22 please...

Microsoft has released the source code of MS-DOS 4.0(1) on Github. Also older versions previously released are there. https://github.com/microsoft/MS-DOS

Smartdrv needs emm386 to be installed.
