quorum128

has anyone connected the flop controller to the subject?
there are problems.

Bay-bye, All!

I have connected it more than once, what are the problems?

Is it possible to add TR-DOS to the standard quorum ROM?
If there are any diagrams or FAQs, I will be grateful.

Bye-bye, Kamil!

If this is a factory Quorum 128 produced by
NPO "Vector", then it contains ROM 27с512
64 KB.
4 pages of ROM contain:
0 - ROM Menu
1 - TR-DOS 5.03 emulator
2 - Basic 128
3 - Basic 48
Emulator TR-DOS works only with a controller
CP/M-TRDOS produced by the same factory.
To work with a standard TR-DOS controller
in its place you need to flash one of the options
ROM for such controllers.
I usually flashed TRDOS 5.04.

There are all the circuits, since I was involved in the development
of this Quorum.
I can send it, preferably by e-mail.
In general, connecting to the system connector does not present any
difficulties.
You just need to correctly connect the /IORQGE (B13) circuit
to eliminate conflicts between TR-DOS ports and computer ports
and the circuit for turning on the ROM page /TRDOS (A23).
The system connector has 28 contacts (in position 5
key) A - upper B - lower contacts.
The first of these signals when selecting TRDOS ports
is pulled up to +5V (usually an NPN transistor).
The second zero level turns on the ROM page with
TR-DOS firmware.
Both control signals are taken from the trigger,switched
by command sampling signals at addresses 3Dxxh and (ADR>4000h).

damn, no words. comprehensive answer. This is exactly what my brother and I were missing.
and IORQGE is spot on! in short, thank you!
