CDROM for everyone

I have one. But the main computer is Scorpio.

KS> My proposal is as follows.
KS> Responsibilities of the performer
KS> Develop software in 30 (thirty) days

Probably 30 days is not enough. But you can try.

KS> Additional responsibilities of the parties. In an informal style,

I have such a controller.

Me too.

It’s easy for isdos. The lack of documentation for the CD is a big hindrance. Screw driver underisdos
I wrote, I think it can be used as a blank for making a CD driver.

2All: someone write a thread on the document on CDs, please!

KS> Develop
KS> a detailed description and HELP for all implemented software.

Easy.

KS> Provide

I know of 5 controller models.

Oh... In short, I’m going to do all this in the near future. Now I'm looking for a less expensive CD, somewhere around 4-speed will be enough. I don’t have any extra money, so
and I don’t have a CD either.

The main problem is that my power supply won’t handle that much. :(
The sidyuk eats a lot at the moment the engine starts.
And without a screw it’s hard, so there’s no desire to tear it off.

So everything stands still. :(((

WBR, Jason.

Once, 04 Dec 98, someone Valerij Kozhevnikoff wrote to Konstantin Sviridov
on the topic 'CDROM for everyone'...

VK> I know 5 models of controllers.

Which ones?
Is it possible to install two devices everywhere? After all, otherwise you will have to take out the
HDD, and if a person has a HDD, then most likely ISDOS is there, and how to work
with a CDROM without ISDOS? Really with FDD or RAM?

Sincerely, Evgeniy aka EVP.

EP> Which ones?

SMUC (Scorpion)
ZXNext
KAY
Profi
ATM

EP> And is it possible to install two devices everywhere? After all, otherwise you will have to pull it out

Everywhere. It’s almost like in disk drives: all signals go to all devices, and
which one to choose is up to them to decide (there are master/slave jumpers).
