Hello, Andrey!
Somewhere on 06/26/00 around 22:58:01
Andrey Eismont issued a line
there is no one All,
about GMX...

Why do you need it? For Pentagon compatibility? So it's cheaper in
dig around in the trash and find the payment. what else can he do? there is no software and
it looks like it won't. In general, ask the Scorpios, if not local -
Zerova, MOA, Kamenskikh... You don't need Zonov - he'll load it... ;)
In parallel, question 2all: no one knows ru7 on scorpion is needed
regeneration? Otherwise, on ka1024 megabits it is not needed (there ula
seems to be regenerating) - I turned off rfsh and everything worked, except Elite3n 8I
And then I bring the Dma controller to mind, and with memory
troubles :(
That's all. Bye, Andrey!
The rifle is a holiday!

No, but the impressions from him are the best.

My eyes fall onto the table from the feeling of rulez! Everything Kano talked about at Inlight'96
made in subj. Everything down to the smallest detail.

Definitely! You can easily break off the Pentagon people by saying, “I have this
Dema works on Scorpio exactly the same as on your Pentagon and I don’t wait
I removed it and didn’t fix the int" :D Well, or something like that. Everyone on CC999 is the coolest
The demos looked at GMX and NOT ONE was bugged.
subj, as far as I remember, 5 different circuits emulate 1 in 1. Here you have 5 in
one. :)

I would also take it, purely for the sake of compatibility with the Pentagon... There is so much memory personally
I don’t think I need a thick screen IMHO, no one except Misha’s Dickie under
resp. doesn't use dosx...
A childhood dream is for Zonov to develop the gmx into a full-fledged Scorp-2000 (relocating it to
gmx is the little that remains on the Scorpa board and adding a couple of slots) it looks like this
and die with a dream... although I wouldn’t mind if the fat one was killed at the same time
graphic mode and instead of it a fast text mode was introduced;)
With best wishes, Vladimir.

Isn’t it easier to find a Pentagon with a fat memory and tasty features or a Scorpio
which turns into a pentagon with a flick of a toggle switch ;) or this dream
Make every Scorpio member compatible with the Pentagon without much effort?

yes but alas and ah :(
By the way, about the text mode, I remember when I didn’t have a modem, but I
brought fresh zx news, I read there about the graphic screen for the Spectrum andimplementation of this soon, it was also described how easy it would be to write a driver
for is dosa and remake zx word. I would be very interested to know how
How did this project develop and at what stage did it stop and why?
Adios

y comrade, the required 2 meters are determined only by the attached test,
everything is always glitchy. Then think for yourself.

Actually, not a PLM, but an FPGA :) (EPM7064). Firmware for the second FPGA FLEX8000 is contained
in ProfPZU v5.0.
However, either Trident is the only living owner
(buyer) GMX, or people who have GMX don’t visit the forum on principle
- no one else had this scheme.
Hello Orionsoft
Ori> did Zero give this to him from the scorpion?
Trident states that the diagram was supplied with the device and description. Then
There is, in theory, all GMX buyers should have a scheme!

If you find FLEX 8000, no problem.
Hello, Electrician
> That is. FLEX8000 is no worse. By the way, where is the firmware for the subject?
There are two FPGAs on board - MAX7000 and FLEX8000. The first one must be recreated yourself.
Since the logical capacity of the chip is small, IMHO it’s possible to do it. But under
FLEX8000 is in the ProfPZU firmware v5.0 - “computer circuits”. Read
description, the addresses of the dumps are indicated there. In principle, a one-piece copy of GMX with
You can reproduce it if you want, but only after hacking the EPM7064. But, for
this will not work for mass production - in a year or two the FLEX8000 can already be
missing :( Therefore, the conclusion is that you need a decompiler (decomposer) of the FLEX8000 firmware!

If this topic is still interesting to anyone, then the chip you are looking for is called EPF8452ALC84.
Hello Orionsoft
Faith has passed, but hope and love remain
Does anyone have positive experience in modifying the yellow board?
turbocharged to compatibility with gmx?
I did everything as described in the book (except for access to trdos ports and output to
system bus of the new cpu_clock signal), and the only thing that was possible
will achieve - this will indicate how much memory has been found and press delete
zero response to keyboard
does not respond to reset
After power is applied, anything appears on the screen
the only tool of influence is the turbo button
if you close it a couple of times. then maybe a miracle will happen and
The only message that was achieved appears.
In general, what to do... I don’t know
also baffled by the lack of a resistor on the 6th leg of the cpu which
should be...according to the depositor's manual.

Hello Orionsoft
Orionsoft, please read the private message, I have something to do with you :)
