Re: MZ-1E14 replica

The MZ-1E14 will not be suitable because we have 1 EPROM with QD management integrated in the MZ-1500 and an external EPROM with another QD management. I think the MZ-1E19 version must be more suitable for the MZ-1500. In addition, the software cannot be integrated into the external EPROM (on MZ-1E1...

Re: MZ-1E14 replica

Does the MZ-1500 use the 9Z-504M monitor which is the MZ-800?
We must be able to find the signature directly in the EPROM.

Re: MZ-1E14 replica

On the MZ-1500 the QD interface is integrated in the EPROM (??) of the machine. Maybe an MZ-1E19 type interface used on MZ-800.
I also have a replica of the MZ-1E19 interface for MZ-800 in my circuits.

MZ-1E14 replica

EN: Good morning all, Here is my last replica: the MZ-1E14 Quick Disk controller for Sharp MZ-700. I had a little trouble finding the contents of the EPROM as it does not exist on the official site or on the old one. The interface worked perfectly the first time and is based on the diagram in the MZ...

Hu-BASIC

Hello,

I am looking for MZF or MZT files containing programs in BASIC of the Hu-BASIC type to have examples of programming in this language.

Thank you.

Re: USR()

Possible! Not having analyzed the complete code of s-basic 1z-013b.
It seems to me that there is a whole working environment in the form of memory locations and that saving this environment is not necessarily essential ... to be checked.

Re: USR()

On sbasic 1Z-013b, USR can be found in $3305: USR: CALL $57FD; Syntax check for open parenthesis CALL $4D65; Evaluate the expression (HL) and provide a 2-byte value: Address PUSH DE INC HL CP 29 JR Z, USR_1 DEC HL CALL $3332; Comma syntax check CALL $4DBC; Evaluate the string expression and provide ...

Re: Beyond

After code optimization I get a wav of 1m33.59s. I doubt it will be possible to do better. I do not know if it is possible to modify the game itself and publish the modifications in view of its publication by sharpworks: I would like to offer a version with choice of more or less difficulty compared...

Re: Beyond

I'll try to optimize the code, since it's a compiled program so there is some headroom, and maybe I'll reduce the size significantly further.

Re: Beyond

In this version, the decompressor is part of the code, it is not integrated in the header of the MZF.
In the decompressor version in the header, we have a wav duration of 99.1s (1m39.1s).
The difference is not visible when loading.
For information, the delta is 3.
