Illesztések / Re: SD-kártya interface cartridge-ben
« on: 2021.March.31. 10:26:51 »
Igen, még mindig vannak nyomtatott áramköri lapjaim, hogy busz-bővítővé tegyem. Még az ellenállási tömböt is be tudom illeszteni rá.

Yes, I still have PCBs to make you a Bus expander. I even can fit the resistor array on it for you.

Interface / Re: Internal memory expansion plus USB
« on: 2021.March.28. 07:43:54 »
You are right. I tend to think all as a challenge. Once having lots of memory and a way to load files, Roms can be emulated.

Simplicity is also important.

Sorry, as usual I have not explained me well....

I mean to add a 5v FlashRom on PLCC packgage, there are SMD sockets for it.

Or it can be totally soldered, on PLCC or TSOP encapsulate, but then you need to take the /WE signal from the EP mainboard. Zozo can modify his SD cartridge updater software. It also uses AMD.

Have you tried to use the bottom side to put the Eprom Socket alone? There is enough space for it.

I tried it successfully on one of my Saint's memory expansions. What I did was to solder the flashrom chip pins to the Ram chip pin-tips on the underside.

 



Clarification: not all pins where soldered, as some signals go in different pin positions on FlashRoms and Rams.

Great. Matching colour.

Yes, it would be great to execute :BASIC PROGRAM.BAS  .


Edit: And on a Tape based EP? it would put the relay on and search for the file.... marvellous.

Ma kiderült, hogy a kollégám régi EP arc, a Kopácsy volt a főnöke.
Ő írta a MIDI-s szoftvert!

Tehát Jeffrey magyar! Hiányzott az üzenet elolvasása, és most elnézést kérek a Kopácsyval szemben támasztott kételyektől a Midi felület projekt kapcsán.

Mondd meg neki, hogy a szoftvere még mindig életben van.... de még mindig befejezetlen....

--------

So Jeffrey is Hungarian! I missed to read this message, and now I apologise the doubts I put on Kopácsy about the Midi interface project.

Tell him that his software is still alive... but still unfinished...

A Mouser-en az 1 Amp Traco Power ára az utóbbi időben kevesebb mint 4 € -ra esett.

On Mouser, the price of 1 Amp Traco Power has recently dropped to less than € 4.

Yes, but the EPDOS as extension also installs Roms the same, so an user with lots of Ram can still manage Roms.

(This is version 1.7, only legacy drives, A,B,C,D and E)

EPDOS has other valuable utilities for a developer, because it has powerful commands to peek on the inners of the operative system, for example returning lists of Ram/Rom segments, channels and devices.

A better option, I think, would be to use the Basic launcher source code we had, to make a simple command.

I mean, to use the functionality on EPs where there is not possible to install the EPDOS Rom.

Not entirely


Thanks for your clarifying explanation about how the laser printers work.

What I mean is... when you think on a laser, it comes to our mind a very high temperature beam... but is the precision not the heat what is important on both processes.

So you use the same technique than the Laser printers. Great!

Lézer, festék vagy mindkettő? Röviden elmagyarázná a technikát?

Laser, dye or both? Would you briefly explain the technique?
