Ciao Luca, la risposta si trova tra le righe dei messaggi in inglese. Provo a sintetizzare per risolvere una parte dei tuoi problemi:

> non so se entrambi i floppy drive funzionino e non so come testarli
Se l'MSX parte senza tastiera, allora dovrebbero partire anche i dischi. Devi quindi crearti dei floppy disk che partano in automatico. Prendi un floppy disk da 1.44, chiudi il secondo buco, formattalo da 720KB, poi prendi un gioco messo in immagine DSK (ne trovi in giro), scarica l'utility Disk Manager, apri il DSK con questa utility, quindi scrivi su floppy l'immagine. Inserisci i floppy nell'MSX e accendi l'MSX, il gioco dovrebbe partire in automatico. Potresti prendere il DSK di un gioco che supporta l'FM-PAC, quindi se accendi l'MSX con la cartuccia inserita faresti il test di funzionamento di questa scheda audio.

>non ho una tastiera e sembra che io non possa comprare
Forse vanno bene quelle del Philips 8280. Oppure esistono degli adattatori gia pronti che ti fanno usare le tastiere PS/2 del PC. Prova a cercare in giro, forse li trovi nel sito di MSX Calamar.

>In ogni caso quando avrò delle risposte aprirò di nuovo il mio msx, ma dovresti dirmi tu come fare e dove guardare".
Dovresti aprire l'MSX e leggere le sigle dei chip che hanno dimensioni piu grandi. Tipicamente questi sono i chip: VDP, Z80 e PSG. Siamo particolarmente interessati al VDP. I VDP dovrebbero essere marchiati v9938 oppure v9958. Forse la tua macchina è talmente speciale che li possiede entrambi.

Facci sapere, ciao.

Hi!
This weekend I was so busy that I haven't got one minute to thank my "msx-friends"!
I got very good news:
1)Friday night I worked all night on how I can create a floppy from a image and... I did it! I've used Disk manager tool and I learn how to use it all by myself, even before talk about this wonderful software here (I'm so proud of that, my first step in msx word). I' ve played aleste, aleste gaiden, aleste 2, undead line, xak 2, war of the dead 2, midgarts, rune master and nyancle racing... all this games are selfbootable so I haven't got any problems launching them. I wasnt able to run vampire killer, laydock 2, famicle, xevious, golvellius 2 and maze of galious (sigh Sad ) - some are bad dumps (i cannot use disk manager with laydock, for example) other maybe need a command from the keyboard (maybe)....
In any case I was so happy and proud of myself: finally I was able to test my hc-95 (msx audio is fantastic!). But I got two questions:
A)I still don't know how to test how to test if disk drive b is working... can someone tell me a game which needs both floppy in both drive (like the x68000)?
B)the scrolling is so bad! I love shumps and there is huge slowdown sometimes (in every shump I've tested), plus a lot of sprites flickering.
C)I'm using a mega drive joypad via capcom adapter (sold with SFII for x68000, tomorrow I will post the pics) and it works fine, do you think it can damage the system?

Now with quotes:

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

thanks msxholder, are you the only one with the hc-95 in this forum? If so you can help me much more than anyone else here... are you italian too? Do you have the same model of mine? when i turn on the turbo the scrolling is perfect but the image is completly broken (tomorrow I will post the pics) and sometimes the games don't start (first aleste, for example). I've always tought that the turbo swich has some incompatibility problem but none of my games seems to support it properly... maybe because I've connected with s-video and not with rgb?
http://www.1000bit.it/scheda.asp?id=330 The nms 8235 hasn't got a keyboard, how can I connect to the hc-95?

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

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

mars2000you wrote:

An RAM extension should also be a good option, because many disk games require at least 128 KB RAM.

Thank you mars2000, are you sure that hc-95 has only 64kb of ram? because On the front of the machine it's written main ram 256 KB/ video ram 128 KB.

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..

You're sooo right! ;)

jltursan wrote:

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.

jltursan wrote:

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

jltursan you're the best! After four pages someone who write me this simple word: DISK MANAGER! When you wrote this I was already playng Aleste 2, but thank you so much in any case!

Manuel wrote:

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 :)

Thank you Manuel, Psycho Wolrd is a good platform with some rpg elements

Forse vanno bene quelle del Philips 8280. Oppure esistono degli adattatori gia pronti che ti fanno usare le tastiere PS/2 del PC. Prova a cercare in giro, forse li trovi nel sito di MSX Calamar.

Ciao enribar, grazie del supporto... purtroppo la tastiera che possiedo è proprio quella dell'8280 e (come puoi vedere dalle mie foto) non matcha con il connetore tastiera dell'hc-95. Già fatti gli altri test e sembra andare tutto bene.
Appena avrò risolto l'enorme problema della tastiera (ad esempio capire se mi serva o meno uno slot expander dal momento che non ho ancora capito quanta ram ha il mio msx, oppure perchè quando accendo il turbo lo scrolling va che è una meraviglia ma lo schermo è completamento incasinato) vi darò volentieri una mano!
Ps: ma se c'è msxholder che, a quanto pare ha tutta la famiglia victor al gran completo, ed è SICURAMENTE più competente di me, perchè non lo chiedete a lui?

Now I will write and post in the keyboard thread my new discovery about the keyboard, in any case I will post it here too...
thank you!!!

There are 2 hc-95 models :

-'normal' hc-95 has only 64 KB RAM and the "normal' MSX2 VDP (V9938)

- hc-95a has 256 KB RAM and the MSX2+ VDP (V9958), but not the BASIC 3.0

So, apparently, you have the upgraded version Smile

Is it possible to know how much ram of the msx from the boot screen?

You need to run the following tool (from disk) :

http://crap.tsk-tsk.net/msxmem2.zip

Rename MSXMEM2.BAS as AUTOEXEC.BAS

Boot with the disk in drive A

Hi, hope to get some good news!

I got both hc 95 pinning is similar !
you need an 74ls145 for decoding 4 line to 10 line or 74ls154 4 line to 16

Thank you msxholder... I don't even know what 74ls145 is. Since you got both models can explain me, or to someone else in the forum, how can build a converter? We've got hc-95 and 8280 pinning... without the decoding is it possible to make it works (even not perfectly)?

it's strange because mine has this uber rare 20 pin connector:

Indeed! If you compare with RS232 connector, you'll see that pins are arranged like this:

* * * * * * * *
 * * * * * * *

While on the keyboard connector it's like:

* * * * * * * *
* * * * * * * *

That's very unusual for a sub-D connector; good luck finding one like that. Evil So unless an original keyboard can be found, you'll probably need to bypass that connector & add another one in the back of the casing.

Hi retrotechie, I've finally found this:
http://karve.en.alibaba.com/productshowimg/378444066-2100088...
Is it the male uber rare dsub connetcor of my hc-95?

RetroTechie wrote:

What matters is not what the connector looks like, but what signals are on it & how they're used. If you compare with a few service manuals, you'll find it closely resembles keyboard signalling as used in Sony HB-F700 machines (see page 37 in that service manual).

I've found Bas Ditta site, he has a lot of hardware and modification on his shop. He's really expensive but... if we can find the right instructions from msxholder, do you think that he can build me a converter for my 8280 keyboard?

Hi Luca, if you add e-mail address to your profile, I've got something for you.. Big smile (a disk full of test software, auto-running & selectable using a joystick).

Btw. is it not possible to find a HB-F700 keyboard? 8280 keyboard is probably more complicated to attach. As if this problem isn't hard enough already for you! LOL!

Another question: is it possible to find another MSX hardware 'guru' anywhere near you? That would help a LOT. I can't help you there since I'm in the NL.

Yes, it can be made with Disk Manager (right-click, then rename); don't forget then to save the modified DSK.
