Re: Astronomy Programs

Thanx! I only got a couple of books with my new (to me) Zeddies, but this was one of them. Saves me some typing!!! :-) I also noticed that the "bookmark" the previous owner was using in that book was a piece of paper with hand-written functions.. I kind of recognized one of them, but that stuff was ...

Re: Starting Composite Mod

Thanx! OK, got the K on my monitor!!! I did have to turn up the brightness a tad, but I will probably put in a ZX8-CCB later. This was just a proof of concept. (and I am trying to decide if I do a ZX8 or the new ULA chip when available, or one of each (I have 2 Zeddies)) Also, I was able to get my k...

Re: Starting Composite Mod

(And I am posting JUST as I see a reply.. Thanx Mark, that makes sense!!) Yes, talking to myself. ;-) Ok, I hooked up some power and set the multimeter to 10v (lowest DC voltage setting). I get basically no voltage (well, the needle did twitch) on the first wire, so that looks to be the video IN fee...

Starting Composite Mod

OK, on my TS1000... I was going to start with a basic composite mod. Just the 1 transistor 1 resistor one to start. I opened it up and have been looking around. It looks nice. (A little too nice. I had some keys also not working when I started it, but the ribbon cable looks nice... Hmmm. Different i...

Re: New member from Oregon, USA

OK, I thought this was awesome. I found out that I have the instructions for the Sinclair 16k RAM pack. I love this bit: A little mental arithmetic should show that the computer can theoretically handle up to 960 program lines when fitted with the expansion pack. In practice, no program is likely to...

Re: Difference between New rom and Old Rom

1. how was assembly done (Tried to ask the same thing on AtariAge, turned into a clusterf**k), what are some code examples? I don't have any answers, sorry. But I can see why you are asking... It is confusing... This is a er.. um. quirky?? system.. First I learn that you can't actually save your pr...

Re: New member from Oregon, USA

Glad to see you've caught the bug! Yep, guilty. ;-) As for the printers, the 2040(known as Alphacom in the UK and sold by Tandy) is the one to persevere with. no need to cut down fax rolls as any 100mm till receipt thermal paper roll will do the job.(served me well for thirty years) Good to know. I...

Re: New member from Oregon, USA

OK, more evidence that this purchase and I were meant to be... ;-) My purchase also included 2 printers. A ZX Printer and a Timex Sinclair 2040. I haven't tried either printer (I did get 6 sealed rolls of paper that I think are for the ZX Printer), but I noticed that the only power supply I had for ...

Re: New member from Oregon, USA

... manuals are like gnomes or mushrooms around here! Yep, I used to always swing by the computer book section when my wife and I would hit the used book stores, but I never found any good computer manuals... I finally stopped swinging by to check for them. Still no idea where my wife's sister foun...
