-New text compilator function to use like [HEX: x,x,x,x] , [DEC: x,x,x,x] or [BIN: x,x,x,x]...
1 REM [TX6: Mytext + $0A character at the end]

Convert a 8bits ascii text to a diet 6bits Zx character.
The compiled binary string in a REM will be chained ...
111111-11 ;1111-1111;11-111111 = 4 characters in 3bytes.

Vb81 XuR release 12/05/22 (Quick update/Vb81 need to be installed with "VB5 fr" DLLs):

[Vb81] Minor Bug Report and request

Post by GCHarder »

The printer output has a minor bug in that only the first line prints 8x8 while others are printing 8x7, or overwriting the last line of pixel from the previous line, see the fig. When using the standard ZX81 characters this only affects the , and ; characters. But could affect UDG characters more seriously.

Also would it be possible to have the option to save printer output as a text file? The fig. shows some AY data I would like to save as text. Using OCR works pretty well but is prone to errors, as you know.

Thanks;

Greg

Hi Greg,
I will have a look to the Zxprinter bugg...

But, to get an ASCII input on the printer, you had to choose the Memotech IF printer (or the AGB Centronics printer card).
Just select the printer, perform a reset to install the rom and open the Printer window.

You will be able to write the printer buffer in the "Printer_Out" directory "Printer_CIF.txt"
"Printer_SIF.txt" is the serial Memotech card.
"Printer_Cen.txt" is the AGB Centronics card.

No update needed.

Select the AGB or Memotech IF/SF card:
if1.JPG
Open the ZxPrinter Window:
if2.JPG
LLIST & LPRINT will feed the printer buffer: (Copy/paste the data to your notepad or retrieve the buffer!)
Note:
It's the RAW printer datas, and all graphics characters are translated to ASCII datas throw the Memotech ROM routine...
To export a basic text program, prefer the SAVE"MYPRG.TXT" feature directly in the Zx Basic monitor. (can be reload by VB81 as is, with the proper encoded characters)
if3.JPG

OR ...

Display all datas on the screen and make an INKEY$ loop or a PAUSE, then create an ASCII screenshot in "file" menu (shifted F11)
"Ascii_Screen.txt" will be update in the ScreenShot" directory.

OR ...

Select the Sound Ay debugger in the sound setup board... (the window will appear while sound playing)
if4.JPG
You can copy the datas, but the buffer length isn't saved and we had to stop the code to display the right sound list...

Re: [Vb81] Bug Report Memotech CIF

Post by GCHarder »

When "Print to the Memotech C. I/F Centronics." is active these errors occur

EXAMPLE 1

10 PRINT "NO ERROR"
20 PRINT AT 0,0;"5/20 ERROR"

EXAMPLE 2

10 PRINT AT 1,0;"B/10 ERROR"

Is it supposed to do that? This is the first time I've tried the Memotech CIF printer. Maybe a system var is set wrong somehow.

The "Print to the AGB Centronics." appears to work OK.

This was a weird one and was driving me crazy until I remembered the Memotech CIF was active.

Also, are you interested in UI corrections and suggestions, such as typos, misspellings , etc.? See the attached for an example of what I mean.

Regards;

Greg

Hi Greg,
The Memotech patch the Basic ROM from 2166 to 2295.
128 bytes rerouted to the ROM placed at 10624.
The "Patch" on the printer UI picture.
The IF ROM rewrite the piece of BIOS, and the "PRINT AT", cursor location seems to be affected by this "patch"
I had to disassemble this part of ROM to target the problem.

Emulator code: Where addr is the UC address pointer MEM() is the zx memory array.

Code: Select all

    Case 1 ' Memotech C. I/F card.
    ' Mirror card ROM segment
    If addr > 2165 And addr < 2295 Then
     peekb = MEM(addr + 8458)
     Exit Function
    End If
 
And... And... the weird icon is an old artifact to display/on-off the Zxprinter.
I had to let it down, the picture refresh for on-line and buffer/busy was too speed to be displayed.
In fact, it's use to "Close" the ZxPrinter window... And, that all.

"Reset" seem to be a good alternative !

Thanks Greg,
I will have a look to it...

PRINTAT.JPG

Four ROM tags/jumps affected by the patch...

We had to change the ROM dump to preserve the Basic ROM bios...

[EDIT] Checked, and seem ok... May be a bug in the CIF ROM...
