Retro-Bit Super Retrocade with Capcom, Data East games

[Retro-Bit Super Retrocade with Capcom, Data East games]

Does anyone know if the Composite Video output on the Retro-Bit Retrocade would work on a European PAL tv? I'd like to try one of these with an old portable crt tv.

[NTSC Games that work on Pal machines]

Anyone know if Activisions Cosmic Commuter (2600) works on a PAL 7800?

 

Thanks

I think Jeri's version was going to be an official Commodore product with a similar price tag as a Plug & Play TV game.

 

It's a shame it never got made.

[Amiga on a chip FPGA by Jeri Ellsworth]

I just found this video about an Amiga FPGA 'Computer on a chip'. It was designed by Jeri Ellesworth who designed the Commodore 'Plug & Play' TV joystick game.

Interesting thing about the Amiga is that the faster ones could also emulate the Atari 800 and Atari ST using software (and probably a lot of other things aswell).

 

I really hope this gets made one day. It would be a fitting tribute to Jay Miners work.

[Park Patrol, Bruce Lee, Zany Golf & Other game requests]

I'm not sure if 7800 programmers like game requests, but here are a few games I'd like to see for the 7800 or 7800XM

 

Park Patrol

 

Bruce Lee

 

Zany Golf

 

Would anyone else like to suggest some games?

[Could the 7800's 6502C CPU run at 7.16mhz or 14.32mhz ?]

Perhaps it would be best to leave everything just the way it is. Too many changes would only ruin the retro experience

 

The reason I asked was to see if an enhanced 7800 could be made, rather than a mod for existing 7800 consoles.

 

I get the impression that programmers can achieve all kinds of things that the original designers didn't think possible, the only problem being that enhancements such as displaying higher resolutions or more colours aren't really practical in games as there isn't enough power to perform hardware tricks and play games at the same time. Even the 7800's 320 x 200 resolution seems to be too much for it's humble processor.

[7800 Expansion Module (XM) hardware & game details - 7/8/2016]

I guess it wouldn't be very practical saving programs to the HSC. Perhaps it could be used as a save game feature or to save data as part of a Game Construction Kit?

[Could the 7800's 6502C CPU run at 7.16mhz or 14.32mhz ?]

A big problem is the memory speed. The 6502 executes a LOT more memory accesses than most other CPUs. A 7.16MHz 6502 runs memory 4 times faster than a 7.16MHz 68000. This means the cartridge ROM and on-board RAM would need to be many times faster, which is not possible with the type of parts and bus used in the 7800.

 

When MARIA makes an access to the Display List List (DLL) or Display List (DL) data it requires two of the 7.16MHz video clocks (that is why they are held in its RAM). If it pulls a byte of graphics data from ROM it requires 3 MARIA clock cycles per access. If you had access to SALLY's RDY pin you could extend the read bus cycles as required (depending on what type of memory was being accessed). However RDY cannot be asserted during writes so any RAM would need write cycle timing to match the CPU.

 

Sounds complicated

 

What if a new 7800 had a Sally and Maria chip that could both run at 2 or 3 times their current speed? Would it work or would the extra speed affect the video output.

[7800 Expansion Module (XM) hardware & game details - 7/8/2016]

That's a pity. It would have been interesting if someone wrote a simple BASIC programming language for the 7800 that used the HSC to store programs.

[Could the 7800's 6502C CPU run at 7.16mhz or 14.32mhz ?]

if you change the CPU getting new games developed is always the most difficult part. Without new games it would be hard to sell such a modification.

 

True. I guess the speed would have to be switchable to maintain compatibility with existing software.

 

To be honest, all this talk of the new XM adapter has got me thinking about what the future has in store for the 7800. It would be interesting to see if the XM project could evolve into a complete 7800 console with a few new features. A faster processor would allow more programs to use the 7800's 320 x 200 mode or display more sprites.

 

Another possibility would be to allow TIA and Maria to work simultaneously to either create more on-screen colours or possibly 2 separate graphics screens, one over the other.

[Could the 7800's 6502C CPU run at 7.16mhz or 14.32mhz ?]

I was just reading about how the Atari 7800's graphics chip runs at 7.16mhz and was wondering if (in theory) the 6502C cpu could also run at the same speed or maybe twice the speed?

 

Just curious

[7800 Expansion Module (XM) hardware & game details - 7/8/2016]

Nice demo. This might be a silly question, but could the Hi-Score cartridge facility be used to store other types of data such as sound data or a small program?

[7800 Expansion Module (XM) hardware & game details - 7/8/2016]

Sounds good! I hope the Yamaha chip could sound as good as this:

[7800 Expansion Module (XM) hardware & game details - 7/8/2016]

Will there be any games for PAL 7800 consoles? A music program to take advantage of the Yamaha chip might also be a good idea.

 

It's just a shame there aren't any microphone, audio or USB inputs and outputs on the XM as something like this might have appealed to computer musicians.

[Is the world ready for an Atari ST Flashback?]

Would anybody like Atari to make an ST Flashback computer?

 

I remember Curt mentioning the idea on Atari Age years ago and thought it was a great idea.

 

Maybe it could be the same size as a Nintendo DS or like a small Stacy portable.

[Two new 16 colour lo-res ST pics]

It's surprising how impressive those pictures look when they are small.

It makes you realise how good the ST could have looked if they had made a portable with a 2 1/2in screen.

 

How many colours do they use?

Ooops, I just read the title of this thread

[The Atari Flashback 3 Petition]

I'm still very enthusiastic for Curt's original Flashback 3 concept--which, contrary to what some people seem to think, is based on the 400/800/5200 technology.

Me too. It's good to hear that the FB3 will be based on an Atari computer (and the 5200 console!).

 

I've always liked the idea of playing Atari computer games on real hardware but found the prospect of buying an unreliable old floppy drive and aging software on disk or tape to be a bit worrying. A Flashback computer with an SD card or USB socket sounds like a more reliable option.

[Anyone tried 'Real 3D' gaming?]

Just wondered if anyone has tried playing games on a 3D TV or monitor?

 

I used to think that 'Real 3D' was just a gimmick, but it looks like it might be the next big thing now that TV manufacturers have found a way of making 3D TV's that don't require special glasses.

[Were there any custom graphics modes?]

It was also possible to to increase the number of colours available by rapidly changing the pallete e.g. http://www.asterius.com/atari/spectrum.html.

Could anything like this be done using the Atari ST's medium resolution?

[Atari 7800 NTSC and PAL models diferences]

Cosmic Commuter is a 2600 game. 7800 Robotron hangs at startup on a PAL 7800.

Thanks

[Atari 7800 NTSC and PAL models diferences]

Most NTSC 7800 games do work on Pal machines, I have quite a few.

 

Has anyone tried playing an NTSC Cosmic Commuter or Robotron 2084 cartridge on a PAL 7800?

It would be good if there was 2 versions of the computer. A classic version for old school computer fans and a high gloss version for those who want a more modern look:

For the record I use as my primary and near-exclusive OS Debian which is about 95% the same as Ubuntu, and have for years.

Just out of interest, how easy is it to get printers and modems working on a non-Windows operating system? I was thinking about installing Ubuntu a few weeks ago but chickened out when I couldn't find a modem driver.
