Amstrad 3" Floppy Drive question
Amstrad 3" Floppy Drive question
Hello,
I'm happy to build my new Cumana controllers, but I have difficult with the drives. I have an old Jasmin drive, so I can use it, but I have 4 Amstrad CPC drives, so I want to try to connect them. The problem is that these drives have 26 pins interface, and the Oric Drives are with 34 pins. So my question is: does anybody know where I can find the 26 pins Amstrad drives pinouts? I can't find any info in the Internet.
My second question is: Can I connect 3.5" drive to Cumana if I reconfigure the drive to be set as "A" drive?
I hope for useful info
Thanks in advance,
George

How many 74LS221 you need? I have bought 10 today for 1 euro per peace.
FDC9216 are here:

I have bought 5, so the people are serious.
Later I thing I can say you where to buy MB8877A.
But the main problem is floppy drive I thing. Tommorrow I'm waiting an old TEAC with jumpers, so I will set it to "A" and pray to work. Wish me success

mmm just one small question. As 3.5" floppies are getting quite uncommon and I can also find some here at work, are there any restrictions about the drives which are usable with the Oric? Any 3.5" drive could work with, for instance, a microdisc contoller?ibisum wrote: I have the opportunity to find floppy drives here at work quite frequently, also ..
HD vs DD
Don't need DD drives at all. I'm happy to say that I've hust connected HD flopy drives to Cumana and they works fine. I just wanted to connect 3.5" driveas first drive to avoid booting from 3" drive. So the models I have succes are:
TEAC FD-235HF 6291 - the easy option - it has jumpers at the back for choise "A" or "B" drive
TEAC FD-235HF C282 - it needs opening the cover and some careful soldering
ALPS D33113 - same as TEAC C282 - it needs opening the cover and some careful soldering
The soldering is needed to breac connection between smd connection DS1 and carefully connect smd connection DS1.

The thing is that I have access to several old computers which include 3.5" floppy drives, and I am not sure if it would be a nice idea to grab one or two of those in case I manage to connect them to the oric using a microdisc controller (real one, home-made or something simulating it)...
Mmmm... maybe it would be a better idea to just wait for the SD card interface

SD Driver
If it will help for SD-driver you're writing and you have difficults building the Cumana, I can build one for you if you have board and I have MB8877A soon.
Amstrad drive
Because of nobody answerd for the question of the topic I'm placing the answer here:
http://www.cpcwiki.eu/manuals/DDI-1%20F ... ual.en.rar
On the page 12 you can see the signals at 34-pin side to 26-pin side.
So the problem is if I want to make this drive as "b" (I want ), because there's no jumpers to set drive number on Amstrad drive. So I must reconfigure the cable.
