In the hc 95 you can swap cable on the floppy controller card
that makes the B drive an A drive and vice versa.
Pinning of cable is the same of nms 8235

And finally: what does this starting screen means?
How much ram I got?

This screen indicates how many bytes are free if you use MSX-BASIC. If you press CTRL when booting, the second drive will be de-activated and you'll get 24990 bytes for MSX-BASIC. If you press SHIFT when booting, both drives will be de-activated and you'll get 28815 bytes for MSX-BASIC (in this case, you need to use tapes).

The Victor HC-95 has 64 KB RAM, but you can access to the entirety of this RAM only with non-BASIC programming.

The few disks he tried came with a Philips MSX2, which are 128K machines. And typical software that came with those machines, is designed for 128K MSX2's. So it's quite possible there's nothing wrong with the drives and it's just software not working. Or 20+ year old disks that became unreadable.

The usual way to check would be to format a few disks. Which he can't do because he doesn't have a keyboard to type _FORMAT on. Shocked! Or to fresh format disks on a PC and write some disk images to. Which he has yet to figure out how to do that, and whether that works at all.

Just file transfer would be easy: format a 720K disk on PC, boot MSX, insert disk, type commands to run stuff (in that order). Which won't work due to lack of keyboard. The other way: format a 720K disk on PC, add files to make it auto-run, insert disk in MSX, reset, won't work either because the PC bootsector code makes an MSX choke during boot. So it's either: [boot MSX, insert PC formatted floppy, type] or [format disk on MSX, use PC to copy files onto it, boot MSX with that].

Because it makes EVERYTHING ELSE so extremely difficult, I can only suggest Luca that he focusses on sorting out the keyboard problem first (btw did you ask seller what happened to original keyboard? Even just the connector would be useful). And if possible: spend some time with emulators, to learn BASIC commands, how to use floppies, files, MSX-DOS commands, etc.

In the mean time, it wouldn't be a bad idea to obtain a simple digital multimeter (no special requirements, a € 20 thingie from hardware store should do), and a soldering iron (15~25W, definitely not more than that). Those 2 items are sure to come in handy, and unless he can find someone to do it for him, he'll have to learn some basics on how to use them. For either tool, not difficult even for absolute beginners.

So Luca made things very difficult for himself by getting an MSX that comes without a keyboard, a very rare model at that, not knowing the MSX system, AND doing that not knowing much about hardware either.

is it possible to write bootable disk games (with an old pc with windows 2000)?
If not can somebody write an image and post it in sites like mediafire (from where I can download it and write it on my windows pc), so I can finally play a game on my hc-95?

You have a good read about the matter here: MSX FAQ: Descriptions of several file formats and types.
Check DCOPY PC tool, using this you can dump MSX disk images to real disks using your PC if it has a 3.5" drive. You can also try with Disk-Manager, a great disk tool.

About the disk images, it's easy to find them everywhere over the net...;-)

To test both disk writing and the FM-PAC, you can try with games like "Aleste Gaiden" and "Undeadline", both good games, with auto-boot, and IIRC using FM-PAC sound.

I preferrred DCOPY back in the days, easy to use & does the job. But it's a DOS program, how it works under Windows 2000 or later? (if anyone knows for sure, plz. share). These days I'd use Linux "dd" tool. Just as easy to use as DCOPY, if you can use Linux Wink (for example CD-bootable Puppy Linux would do the job).

Single sided (360K) disks are problematic to write on PC, because it's not a format that PC's recognize (all 360K formats known on PC are double sided with fewer tracks). So even if the write goes ahead the produced floppy may contain garbage.

Easier is to transfer 360K disk images on a 720K disk, and write the 360K disk on the MSX. For the time being, I suggest limiting yourself to the 720K ones... Smile2

Of course, without keyboard, it's impossible to press CTRL or SHIFT, but I wanted to give a complete info about the available RAM, it will be useful when the keyboard problem will be fixed. An RAM extension should also be a good option, because many disk games require at least 128 KB RAM.

DCOPY works fine with Windows 7 32bit. I've also created sucessfully 360KB disks by means of a USB external drive and Disk-Manager Smile

Just write a real disk with your PC with a disk image with a nice MSX2 game with FM and run it. E.g. Psycho World is a good one Smile

To dump Victor HC-90 / 95 Series

Methos is the following.

1. Dowload MSX tools from the following URL.

http://www.mediafire.com/?6sns60te791lh21

2. RUN"KANJIROM.BAS" on BASIC
3. Replace disk with blank disk
4. Select 1 (JIS 1st)
5. If the dump is done, Reboot MSX2 with MSX-DOS 1
6. Run the SAVEROM.COM as following.

A>SAVEROM HC95BIOS.ROM
Primary Slot: 0
Secondary Slot: 0
Select Type: Normal
Begin Address: 0000
End Address: FFFF

A>SAVEROM HC95EXT.ROM
Primary Slot: 0
Secondary Slot: 1
Select Type: Normal
Begin Address: 0000
End Address: FFFF

A>SAVEROM HC95FIRM.ROM
Primary Slot: 0
Secondary Slot: 1
Select Type: Normal
Begin Address: 0000
End Address: FFFF

A>SAVEROM HC95DISK.ROM
Primary Slot: 3
Secondary Slot: 0
Select Type: Normal
Begin Address: 0000
End Address: FFFF

KANJI.ROM must be renames as HC95KFN.ROM

Already HC-95 BIOS is uploaded on bluemsx.com
But it is Not verified. (KANJI ROM seems to be National's one.)

Hi, msxholder.

I wonder how many you have Victor HC-90/95 series.
I want to verify the roms.
