@jltursan
assuming that this module works alright, could it be connected to a primary disk as Fujitsu standards, or even to both primary and secundary?

This opens another possibility ... but you said that ONLY one can survive ;-) I mean external OR internal but not both to deal with
four drives, for instance
thanks

Indeed, the FDC lies inside the station, (an MB8866?, can't remember), this is only some kind of interface to it, as you mention it'll be very close to the one found inside the external interface. The external one is a little more compatible as it can be used also with the FM-8.

This controller could support if I'm not wrong, four drives at a time; but I've never been able (or dare) to test it. The disk station has enough free space to be filled with half-height drives, not sure about watts of its PSU. The old 360KB drives are exactly the kind of drives you need, they are compatible with the pinout, you only need to set it to the correct disk ID (DS0 or DS1...or maybe DS2 or DS3 :-) ) and set also READY jumper (although I'm not totally sure about RDY signal being used in the FM7).

Hi,

I have an FM77L2 but I don't have any software for it. I'm trying to write d77 disk images to a 3.5 floppy using DITT but, but the FM77 can't read them. I read SAMDisk might work but my only PC with a floppy drive is a 486 and can't run Windows 2000. Is there any DOS compatible program I can use to write 3.5" FM77 disks?

I also have a Gotek floppy emulator with Flash Floppy firmware. Most floppy images won't boot at all, but OS-9 ones will display "OS-9 Kernal Started!" and then freeze. Has anyone gotten one of these things to work with an FM77?

Welcome to RW !


.D88 is an image format for NEC PC-88/PC-98 floppy disks.
.D77 is the same format for Fujitsu FM-77 series computers.

This should work: http://ysflight.in.coocan.jp/FM/RS232CDiskBios_e.html

Take a look on your FM7 dip settings:
4-position DIP switch info

(1) ROM mode/DISK mode* (FBASIC mode)
1=ON, 2=ON, 3=OFF, 4=OFF
(ON=UP, OFF=DOWN. Number is sequential from left to right)
*when external floppy disk is available

(2)DOS Mode
1=ON, 2=OFF, 3=OFF, 4=OFF


You may find some more info on (in english) :

http://ysflight.in.coocan.jp/FM/e.html
http://ysflight.in.coocan.jp/FM/D77ToRS232C_e.html

For Windows exist some useful tools to import/export multiple disk images.

Thanks for the links. I tried using D77Manager to copy files from a 2D .d77 file to a 2DD .d77 but it won't boot, even in the emulator. Is there a boot sector or something that needs to be copied over?

Use then the RS232 option, you can built your own discs, it seems to work !

I've never used DOS/W98 to create such disks. Although I can boot W98SE in my tweener, having also an XP results in a killer combo when paired with SamDisk.
If you're stuck in DOS, you can use the aforementioned DITT; but beware that while it excels writing 5.25" floppies into old 360KB drives, when working with modern 3.5" ones it could fail miserably. These 3.5" drives are HDD, while the originals are DDD and that means you need to write the D77 image (dumped with a double density drive) with double-step enabled and that's why you need a tool capable of doing that.
I mean, IIRC DITT doesn't have such feature so you can, I'm wildly guessing now, use SamdDisk in any other PC to transform D77 images to IMD (ImageDisk) ones and then, using IMD, a pure DOS tool capable of write images with double-step, to write the converted images to floppies.

Btw, welcome to the forum!. Maybe you can present yourself here and tell us about your fave machines and if you have an original keyboard for a FM-77AV40SX ;-)

I tried IMD but it gave me some sort of floppy controller interrupt error when I enabled double stepping. Maybe my BIOS doesn't support it. I also tried connecting the FM77 floppy drive directly to the PC and using DITT but it didn't work. I'll definitely introduce myself. I had to make my own keyboard for the FM77L2!

Hi all,

Does anyone know where I might find documents describing the low level FM-7 series tape file format, and the T77 emulator image format?

I'd like to try and get loading from an arduitape style device working.

Kind regards,

Mike

@malikto999
Hello,
I would like to get as much technical info as possible about the FM77AV-2, specially concerning the use of the MMR
in order to program (in assembler) in 320x200 mode with 4096 colours!
Any hint or link you could give us will be of help!
Thanks in advance

Hello,
I think that, once Malik gets in touch with us, it would be better to open a new thread to talk about the FM77AV2
so that info would be easier to be found, let's not mix FM7 and FM77AV ... of course if you agree!
cheers!

Hi everyone, long time no see.
Nice to meet you again.

The new features of FM77AV are described in the feature article "All that FM77AV" in the January 86 issue of Oh!FM magazine.
From that article, I would like to first introduce how to use memory maps and MMR.

If you can create a new thread please direct me there.

I am personally surprised that there is no Fujitsu FM7 FPGA core yet.
Precisely because of the few machines there are and how difficult it is to find them. In Spain it was manufactured under SECOINSA, which is the same machine but westernized.

I guess that these "double CPU" machines could be hard to synthesize, there must be a lot of timing constraints or such...

Hi TurSan !

Not really, there are several cores that have double 68K, others like the C128 have 8510 and Z80 and such... I guess this is not the problem. Two 6809, well,
It's all a matter of the core having a BUS, from there everything is always much easier.

CPU:
68B09 @ 2Mhz main
68B09 @ 2MHz graphics

Optional: ( Thrid CPU xD ) Z-80A in external card to run CP/M

ROM: 40kb: 8Kb monitor program, 32Kb for basic
RAM: 64kb extensible to 256Kb
VRAM: 48Kb

Graphics: 68B09 @ 1MHz <--- this might be wrong.
5 modes
mode 0: texto 40x20
mode 1: texto 80x20
mode 2: texto 40x25
mode 3: texto 80x25
mode 4: graphic 640x200x8bit(256 colours)

Sound: AY-3-8910

@rampa this machine is calling you ! -507

Thanks Ron, goot to know!

Just some fixes to the info above:

Graphics: 68B09 @ 1MHz <--- this might be wrong.

Indeed, as stated, it's 2MHz.

mode 0: texto 40x20
mode 1: texto 80x20
mode 2: texto 40x25
mode 3: texto 80x25
mode 4: graphic 640x200x8bit(256 colours)

If I'm not wrong, it has no modes, all is drawn in the graphics screen that is a 640x200 bitmapped screen with three planes (R,G,B), so 8 digital colors. It's very close to the one in Camputers Lynx; but with higher resolution.
