Re: New member from Oregon, USA
Hey, bonus score.... My TS1000/ZX81's didn't come with any manuals. No biggie... But yesterday I flashed on something.... Years ago, my wife's sister gave me a book on the system. (She and my wife are both both huge used book buyers and it was something she had found in a used bookstore at some time...

Re: New member from Oregon, USA
Awesome!!!
I was wondering about the ULAs, as that appeared to be a possible weak point keeping these guys running...

Re: TS1000 ULA vs ZX81 ULA
OK... After re-reading a bit: The screen area usable by BASIC programs is the same. If a machine code program uses the ROM display system, the same applies. I think I get it!!!! Now it is making me think that if the monitor I plan on using these with is happy with 50Hz, I might convert my units to t...

Re: New member from Oregon, USA
Thanx. I saw some info on the ZXVid and ZX8-CCB. Not sure yet what the difference is. ;-) The research is more than half the fun tho! ;-) I think I'll try to do a manual transistor mod for the TS1000, as the RF image looked pretty good on my TV. I'm thinking the ZX is going to need something more ad...

Re: TS1000 ULA vs ZX81 ULA
Having done the resistor thing mentioned in the other thread listed above I can confirm it works wonderfully, the only difference being the zeddy runs slightly slower at 60Hz. My lack of technical understanding will show up here, but why slower? Aren't there 100 more lines to refresh in 50Hz mode a...

Morning! Just picked up a pair of them last night! My first Sinclair machines! I got a US ZX81 and a Timex Sinclair 1000. I also got 1 original power supply, a 16k Sinclair RAM pack, 2 printers (1 Sinclair and 1 Timex Sinclair), and several rolls of paper. Both of the computers look really nice!!! I...
