Re: Which is better? Spectrum or other....

I went to the world of spectrum site and found a couple of games. I found a 128k and 48k version of lode runner and both play on the MIST with my atari (which I guess the games call it kengsiton or something) joystick. The 128k version plays music and loads fast (after I select the Tape Loader menu)...

Re: Which is better? Spectrum or other....

It first displays a menu of: 128 Tape Loader 128 BASIC Calculator 48 BASIC TR-DOS If I select Tape loader it says (to cancel - Press BREAK twice) - so hitting keyboard keys doesn't appear to do anything unless I hit escape twice If I se...

Re: Which is better? Spectrum or other....

Thanks guys for all the information. I hooked up the MIST this morning and it still works. Can anyone tell me what I can do to test it with the Spectrum core loaded in? Is there a manual I can download to look at? Or just a quick check as I have not worked with it before. I’ll have to get the spectr...

Re: Which is better? Spectrum or other....

I just realized I have an FPGA MIST that provides hardware reproduction of old computer systems. I looked and there is a Spectrum 128K FPGA core available: ZX Spectrum 128K for MIST Board Some verilog models from Till Harbaum Spectrum core were used in this project. Features: •Fully functional ZX Sp...

Which is better? Spectrum or other....

I have had a few Timex Sinclair 1000s modified for video still have a couple with various accessories such as ZXPand+ so for extra memory and not having to deal with a cassette tape machine using an SD card. They are wonderful devices and have lots of memories with all the ZX81 stuff. However, being...

Re: New hardware I/O board using Parallax Propeller

Bean, I like how you did 16K with only 2 chips. However, have you seen Wilf's circuit for 64K (2 - 16K RAMs) which says it's compatible with all Hi-Resolution formats? http://www.user.dccnet.com/wrigter/index_files/Thanks%20for%20all%20the%20Memories.htm I had one of my TS1000's modified at some poi...

Re: New hardware I/O board using Parallax Propeller

Thanks Bean. Yes I have had many propeller cards over the years. I just haven’t played with one in a couple of years. I’m pretty familiar with Spin but only mildly familiar with Propeller ASM.

Re: New hardware I/O board using Parallax Propeller

Bean, I have a zx81 edge connector soldered to a short extender board with solderable holes for a connector between (I have 2 connectors you could solder in). I also have an unsoldered edge connector that you would have to cut down a few spots. I can mail them to you for free if you want. Just PM me...

Re: New hardware I/O board using Parallax Propeller

Bean,

I don't know if it's possible with your setup but I would love to see "Color" VGA" or composite video out of the TS1000/ZX81 perhaps something like the Chroma81 does with SCART for those in Europe - http://www.fruitcake.plus.com/Sinclair/ ... erface.htm.
