Details
In 1995, the most lively subject for all
spektrumistov question was about connecting
Winchester. Two years later, "screw" was
common drive to the Spectrum, one
is not surprising. And it was then became
pay attention to another device
which is now turned into a living subject,
similar to the one that prevailed three years ago.
-= CD-ROM on the Spectrum =
Yes, it is that drive today's most urgent - judge for
yourself: on one CD You can record more than three hundred
megabytes - and this, for obvious example, about 500
TR-DOS'nyh floppies! And the price of a CD-ROM
today is already quite low and therefore so
more desirable to use. But further
discussions and disputes about the CD case, unfortunately, not
matter - the work to be serious, and pay for it, as always,
there is no one ...
One day, a quiet December day,
in fidoshnoy ehokonferentsii REAL.SPECCY came a letter with a
stunning content - its author, Konstantin Sviridov proposed
business agreement on wage work on the adaptation of CD-ROM to
the Speccy!
After a light shock;), we immediately contacted by
Constantine and, with permission to publish, in view of the
sensational material, the same letter to the ZX-News.
Below you will find a brief interview with
Konstantin Sviridov and after the letter, cited as a whole.
ZXN: Your project for connecting CD-ROM to
Speccy - commercial or charity?
Konstantin Sviridov: It is a purely charitable act.
ZXN: And for some reason you decide to
to undertake this project?
Konstantin Sviridov: In this step, I walked out of a desire to
continue its modest contribution to the development
ZX-compatible computers. Indeed, one of the unrealized
projects ZXNEXT was just CD-DRIVE.
ZXN: And what are your future plans?
Konstantin Sviridov: If everything goes
successfully, by February 1999 for all who want be possible to
connect CD-DRIVE to your Speccy, as a full
device. And then we will see, I hope
that the release of a CD-ROM is not an end. The next step can
be adapted Games in CD-version and much more.
ZXN: Excellent! It remains to thank
On behalf of all chitaeley ZX-News for this project and wish
you success in other studies on the Spectrum!
And now we propose to familiarize himself with the following
material. __________________________________________
(C) 1998 by Konstantin Sviridov.
-= CD-ROM for all =
Hello, Dear All!
A little about myself. Konstantin Sviridov, ZXsovmestimymi PC
worked from 1988 to 1995 years. Author and performer of
ideology and all hardware solutions ZX-NEXT (if any
still remember).
My suggestion is as follows. In connection with the
that all implementations ZX-compatible PCs still do not fully
support CD-DRIVE, propose to address this issue on the
following conditions:
1. Participants in this conference are introduced
with my proposal and discuss
the subject matter.
2. By the method transparent and open discussion
in this conference shown programmer (writer, encoder, etc) or a
group thereof, accepted the offer and signed the agreement
(hereinafter referred to as performer).
3. At the specified time performer develops software to support
CD-DRIVE from under the IS-DOS and TR-DOS (The technical part
below). Konstantin Sviridov, hereinafter referred to as the
customer pays for this work in accordance with the terms of the
agreement reached.
-----------------------------------------
The essence of the agreement.
Duties of the customer.
Pay the executor of 500
cu Possible partial prepayment.
Duties of the Executive
Develop 30 (thirty) days of the software (described in the
TOR) on the terms FREEWARE (ie free software) and submit it for
free distribution (as well as source code and documentation).
Including through the conference.
-----------------------------------------
Additional duties of the parties.
In an informal style, but seriously. If
Executive will need CD-DRIVE, I did
granted. In the case of excellent quality
Works CD-DRIVE is a performer. Can provide the IDE controller
on the ZX-NEXT, or bundled with add-on. Includes both
as 512K, AY, Turbo, CMOS, XT-Keyboard CGA,
2LPT, coder PAL and a lot of useful detail.
Just complete documentation, consult with my hand in case of
failure of anything. In addition to around the printer D100MPC
(9 pins), the drive 3.5 1. 44 and other stuff on request. All
that remains of the Executive, if He does the job perfectly
well. Otherwise, pass on to the finish bugs and flaws.
Evaluation criteria will be be a guest at the conference.
I will try to assist in the placement of information
(documentation) in Internet'e, records test CD and transfer
(technical) information from the flop on a CD.
'll Take 10 discs for free distribution to those who are
ready to record any number of copies and sell them no more than
the price the carrier (the maximum plus beer). The only
obstacle is the geographical location (I live in Moscow).
-----------------------------------------
Terms of Reference (subject to adjustment depending on the
wishes of All).
Develop, implement and debug drivers, utilities, and (or) other
software software to support CD-DRIVE storage standard ISO9660
interface IDE. Adapt the software for OS IS-DOS and TR-DOS.
Develop a detailed description and HELP for
only implemented the software. Provide the ability to easily
make changes to the software, with to adapt it, under the
specific equipment.
As options are:
Change the I / O ports for specific models.
Replacement drivers.
Auto-detect hardware.
In any case, the software must be compatible with most
popular models IDE controllers and their implementation.
And, finally, to collect a set of programs
Games, utilities, distribution, descriptions, etc.
forth in the standard IS-DOS operating system and TR-DOS, if
maybe on one disc. Reasonable degree of
the disk is at least 300 MB. Although
the timing and amounts of non-negotiable.

Like everything with a deep respect for all,
Waiting for answers, Konstantin Sviridov, MCNE,
MCSE, a lifelong fan of the ZX-SPECTRUM: Sunday, November 29,
1998.
