Hi Guy, I have finally found the KSCAN 3 documentation. Basically, after I wrote the article for the Hunter Valley Journal, I was not happy with my initial ...
Leslie, Can you plug this keyboard into a normal vz and have it work with the basic interpreter? If so how does this work - using an interrupt routine? Do you...
Hi Guy, This is going to be a long answer.......... I have three different VZ - 101 keyboards each progressing as it were in terms of both ease of connectivity...
A very important location (7816H) exists in communications RAM called the KDCB - Keyboard Device Control Block. This contains the location of the matrix...
... Hi Guy, You will also notice that there are other DCB's in Communications RAM supporting video display and a printer - These are unused on the standard VZ,...
All, Just quickly testing me new dopey email. Got the sack last friday (after 11 plus years) so had to wizz up another email. Just testing to see if anything ...
Hi all, A brand new AMIGA mouse has been listed on Ebay. If this is a Bus Mouse (and I think they all are for the Amiga) then this is compatible with the VZ...

Hi Guy et al, No nothing stopping me at all, just taking an interest and adding traffic - where has everyone gone ? I am still transferring the software - its...

Hi everyone,  Ok, hopefully this *may* get the traffic up a bit ;-)  Now this has probably been discussed before, but as a vz-200 owner, who is scared to...
Hi Leslie, et al. ... Since I don't have a "real" VZ at the moment, I was toying with the idea of doing an implementation of a VZ on a low-cost FPGA board. ...
Hi Leslie (#2!),  Although I have a xilinx-digilent fpga board (Spartan3) among xilinx-based offerings, I never really went anywhere with them as a hobby...

Hi Guy, I wa looking through some old posts and one was from you that implied you had written a Z80 program on the PC and loaded the compiled result into the ...
Z88DK supports inline Assembly: http://www.z88dk.org/wiki/doku.php/usage:inlineasm It also has VZ extensions: http://www.z88dk.org/wiki/doku.php/library:vz200 ...
Yes that waffle makes perfect sense to me. I think the VZ editor assembler is great for preservation purposes and to play with every now and then but for...
This is very good for mixing C with Z80 assembler. Eg you can define a C function and have the implementation in inline assembler. Handy for high performance...
