Re: How to perform a Timex Sinclair 1000 internal memory upgrade?

I am interested in both WRX for high-res as well as UDG.

Battery backed ram sounds interesting, and I do have some tiny LiPo batteries which might be perfect.

I ordered some 32k SRAM chips over a month ago from China. Still waiting for them to slow-boat over here. Zzzz.

Re: Photo of my TC-2048

Tested it today and everything works great except for the TV output (composite monitor output works fine). I'm very happy with the computer as it is. The seller was very accommodating and helpful. Are there any use cases where the TV output would be desirable? I can't think of any, other than actual...

Photo of my TC-2048

Had this beautiful item shipped in from Portugal. Gave it a good cleaning before setting it up for a photo.

Forgot to buy a power supply so it's just sitting pretty here until then.

Re: EightyOne ZX81 emulator does not have a 56kB RAM option?

What is the relevance of this as an exclusive option?

You need to enable RAM in 8k - 16k area as well.
This is already enabled by default. I just get a blank screen.

Can this game be played on EightyOne?

https://github.com/charlierobson/zedragon I am trying to load the file zendragon.p without success. RAM at 8-40K : Chroma / ZXPand / ZXpand+ UDG : UDG-For-ZXpand / CHR$128 mod (128 character mode) Set RAM to 32k. Set Chr$ Gen to "CHR$16". Does this need something else for "CHR$128"? Maybe ZXpand+ UD...

Re: How to perform a Timex Sinclair 1000 internal memory upgrade?

I'm having trouble following what I'm reading online. Can an internal modification be performed to increase the available SRAM to its maximum of 56kB (+ 8kB ROM for 64k)? I'm finding documents indicating how to upgrade the internal RAM to 16kB or 32kB but then I only find information about 64kB when...

EightyOne ZX81 emulator does not have a 56kB RAM option?

I noticed today while experimenting with emulators that No$zx has an option for 56kB RAM. This is expected as the ROM size is 8kB and this would add up to the maximum of addressable 64kB. But EightyOne does not have this option. Does anyone know why?

Hello, friends!

I grew up in the 16-bit era of computers and have come to realize later in life that I missed out on the fun and exciting age of 8-bits. I've enjoyed watching lots of videos and documentaries on these old computers and often wondered which, if any, I would have gravitated towards had I had the oppor...
