[MZ-700] SDLEP-READER: What is it?

The original link in French is here Author: Daniel Coulom - Website: DCMOTO Emulator - Last updated on February 5, 2018 Here is a translation: SDLEP-READER is an Arduino-based electronic editing. It allows TO and MO tape recorders to be replaced in playback, using "cassette image" files st...

Re: [MZ-700] SDLEP-READER: TEASER!

Ok, the original turbo loader had a hardcoded value for DLY3 to $15 which is for 3600 baud. I think SDLEP-READER may have a hard job to cope with 3600 baud (firmware delay granularity is 50 µS). By setting $1F instead (2400 baud), I was able to read SEND-1 at 2X speed. However, I have found this art...

Re: [MZ-700] SDLEP-READER: TEASER!

It works but it has an annoying behavior. I may need to invert the MOTOR signal. Now, I'm forced to connect MOTOR and SENSE signals to GND respectively to allow SDLEP-READER to transmit file data and bypass the blocking "[PRESS] PLAY" message. So it means I need to push the RESET button on...

Re: [MZ-700] SDLEP-READER: TEASER!

This is a read-only solution. As the author says, tape solutions are nightmares to use and too slow so he doesn't see any useful purpose to implement it. The reason is probably due to some limitations: 1) File "name" is selected by a 7-bit DIP. So you have up to 128 files. 2) FAT is only u...

Re: EmuZ-80

I bought a MiSTer (Terassic DE10-nano). One day, I'll retrieve MZ cores and check them. I think there is an MZ-80 A core done with a DE FPGA, but it may need some adjustments. Not sure if FPGA implementation of MZ can be fit in emulator category though.

[MZ-700] SDLEP-READER: TEASER!

Teaser for SDLEP-READER working with MZ-700.

Ohoh that magical "LOADING xxx" message!

Re: [MZ-700] Modding a SCART>HDMI to output RGBS on modern TV

If I try to plug the SCART cable to my TV instead of the converter, TV looks for the best signal and chooses a CVBS signal in the end. Here is what I got: SCART_without_fast_switching_on_modern_tv.jpg And closer: SCART_without_fast_switching_on_modern_TV_closer.jpg . I also tried with my first SCART...

Re: [MZ-700] Modding a SCART>HDMI to output RGBS

2) Steal a voltage from a regulator: There are several regulators Regulators.jpg But 1.8V U4 is the best choice for soldering and voltage range matching. I chose the second solution. I noticed that there were two pads just above the 75 Ohm resistor and a trace that connected the two pads. If I want ...

[MZ-700] Modding a SCART>HDMI to output RGBS on modern TV

I have bought this converter because I was told they work pretty good with RGB output for AMIGA. I also read an article about the synchronization issue with Atari when using a SCART on modern TVs and to address it by modding this converter so I decided to buy another one as I was expected to get a s...

Re: Gaming

If I recall well, the MZ-80 K and probably the MZ-80 A are suffering the snow effect on an animated display. I mostly saw them with fast games coded in machine language.
