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.

Re: New hardware I/O board using Parallax Propeller

Hello Bean - It's been a while (Tim Gilmore). You can try to get the edge connectors at this site: https://www.sellmyretro.com/offer/details/zx81-~~-zx80--_-slot-edge-connector-2x23-pin-%28new-stock%29-3823 I had (may still but need to check tonight) a couple of them I got from PokeMon a few years b...

Re: ZXPand+ IDC10 Serial port ideas!

I have been away from this forum for such a long time now due to a lot of things going on in my life. However, let's see if I can get back into the groove. In response to my thread from before about ZXPand+ serial devices, I see that Parallax now has a UART controlled Fingerprint Scanner . I may try...

Re: ZXmore not working after plugging in ZXPand+ and Wiznet board (siggi?)

So true Siggi!

ESD is most likely the culprit.

Thanks. I'm working on another project at the moment for work but will get back to my TS1000 in a couple of weeks or so.

Re: ZXmore not working after plugging in ZXPand+ and Wiznet board (siggi?)

It seems to be good. I haven’t plugged in my ZXPand yet to be 100% sure but feel confident it will work. I just need not to plug in the wiznet ircchat board and ZXPand together. Not sure if that’s what killed the flash rom chip on ZXmore or not but just glad it’s back up again.

Re: ZXmore not working after plugging in ZXPand+ and Wiznet board (siggi?)

I finally got a chance to see what happened to my ZXmore. It was the programmed flash rom chip not the CPLD. All comes on correctly now. Thanks again Karl!

Re: ZXmore not working after plugging in ZXPand+ and Wiznet board (siggi?)

Karl, Hmm Flashrom. ok. Where is that at? I sent you a paypal for euros as described in my PM so whatever I can get for that to help and have spares possibly - please send me. The LED is off on Instance 0. If the ZXPand+ is plugged in (A3 not jumpered with 10K resistance A3), I get that scrambled ch...
