Re: Prism 1000 modem and serial cart

Is it difficult to set up? Not really, just need to specify the address of the Telstar stream: mame dragon32 -cart prestel -bitb socket.glasstty.com:6502 The current Prestel (serial device) cartridge just needed a tweak to set the Rx/Tx clocks, they're hardwired using a ripple counter to 1200/75 ba...

Re: Prism 1000 modem and serial cart

Apologies for digging up an old topic, but this combination of ROM, serial cartridge, and modem will soon be emulated in MAME, and can fully access the online Viewdata system Telstar!

Re: ATV's Curso autodidáctico de informática BASIC tapes

So is this 12 tapes? Can you post photos of them for reference, of each tape side, so they can be labelled appropriately.

Re: The Dragon Meetup returns to Cambridge! 7th/8th Oct

I was intending on attending either the Dragon Meetup or Retro Fest, but as they're a month apart will likely attend both :D

I am using right now MAME240 and I have seen somewhere that there is a 250 version, but doesn't seem to contain this registers
It was only submitted today, so will be in the 0.251 release due on the 28th Dec.

Looks like someone has now implemented this, see https://github.com/mamedev/mame/commit/ ... 7c6bbc1e55

Re: MAME Emulation

It seems that the best emulator that works correctly with the V9958 (MSX2+) is called OpenMSX Count on me if you need someone to test 'provisional' versions or someone that could create programs using 6809 and V9958 cheers!

Re: MAME Emulation

I asume that the emulation we have for the Dragon is based on the V9958, right? Yes, but ... having now looked at the current V9958 emulation I'm not seeing the hardware scrolling registers actually being used anywhere. There's also a bug report at https://mametesters.org/view.php?id=8466 that sugg...
