Osborne 1 formats improved by addind the single density format and the correct disk speed and interleave settings.
Now the disk images work correctly also in IMD mode.

VT-180 disk mode pulled.
Having a good emulation level helps in creating accurate disk images, with transfer speed and skew settings closer to the real ones, raising the probability to get working suff on the real hardware.

that's not impossible, I'm confident that the emulation work better on the v1050 than on the mbc200
I simply couldn't figure out how to make it work

In this way I could verify that the disk format for the Televideo TS-803 and TPC1 is the same of the TS-802.
I'm renaming it in appmake and I'm adding a generic "televideo" subtype.

The Telcon Zorba portable CP/M computer had a lot of disk options, I'm using it to check the formats we've already implemented and possibly find the extra ones which could be nice to have. Well, I'm already disappointed, I can't understand how the IMD format could keep the 1..20 sector numbering wor...

It shouldn't happen, I wondered whether I forgot to update something in the public z88dk tree, but they're 2 files only and they are ok. zcc +cpm -subtype=v1050 -create-app tic.c mame v1050 -flop1 1050-sys.td0 -flop2 a.imd I could run it on a recent MAME build (self-built from the current dev tree, ...

I'm going to pull in the full VT-ANSI engine, which is quite perverse, because it encapsulates the ANSI ESC sequences in an ANSI ESC interpreter ! v1050ansi.png Alternatively programmers can totally skip the ansi VT engine and use the native mode which will accept almost all the ANSI VT sequences, w...

In short, you're expecting sccz80 to force h to zero, right?

I still couldn't find a way to catch the talkback from the video section, it probably requ...

I'm now looking for the way to get data from the video section (6502 controlled).

A handy way to read the V1050 sources is on this link:
http://v1050.classiccmp.org/src/index.html

Sometimes the transmission breaks. I could observe it also with the original GSX driver, so I'm not sure it does not depend on the emulation (I'm using an old version of MESS because I miss some of the ROM images). Passing the parameters as ASCII-decimal values works much better, but sometimes the p...

I finally had to mix BIOS calls and direct out to allow a stable communication.
A first minimal set of graphics is now working, I think I'll open a PR and proceed by steps.

This is another interesting hw, its concept is very close to the Sanyo MBC-200, but the terminal control and graphics were delegated to a 6502 CPU. There's a nice sw set (TOSEC) in archive.org which include the rather rare "DR Graph" and useful original system oriented source code. https:/...

I think it is in a consistent status, now. Considering that mbc_send() has its own advantages in terms of speed and control over BIOS or BDOS, I decided not to change it. It is rather convenient to replace it with a function calling the BIOS on the other Sanyo systems. I can't wait to move on and tr...

It's very comfortable indeed. I must have messed with the underlined text attribute, bit 7 in CAPS, which is tempting me to provide both the implementations (there's very little code in this case) . I should also change the calls to mbc_send in the terminal code (OUTing to the 2nd CPU directly) and ...

I try immediately
I suppose the direct ansi VT implementation is still preferable, right?

> ..you might not have implemented all the functions or be missing the CAPS defc? As usual, you are right. VT52.png This technique has only one possible positive aspect, the code gets probably portable on other, never emulated SANYO models. On the MBC-200/1200 series the attributes work only in 33 r...

What's the best way to alter the existing --generic-console library ? I tried to simply rewrite the functions but they collide with the existing library, I suppose the console code is built on the fly: duplicate definition: generic_console_ADM3::generic_console_printc error: duplicate definition: ge...

I'd really like to do so but I could find a reliable way to access to the video memory directly. All the video stuff is in charge to a twin z80 CPU and something gets garbled. I'm not even sure the output way is 100% stable, even if the normal console operation runs perfectly. The ESC codes are Sany...

Considering the current emulation limits (not confirmed by comparing with the real machine) it is probably convenient to stub a one - way text library to support the z88dk generic terminal, etc

fantastic! if it gets generic we can use it in several cases.

Regarding the library limits, I'm proud I adapted qsort() to the 8080,it should allow the othello game to run

I wrote the missing Wiki page, hope it helps

It is very nice to see the Dallas game run (and play sounds) on the Xerox 820! In theory the x820ii is slightly different, because it the only one supporting the 1bit sound and the 4x4 blocky graphics, but at the moment it is not much an issue, because no working emulators exist for it, I'm not expe...
