Re: TS 1000 Composite Mod
Bill H.,
Try this circuit,
viewtopic.php?f=7&t=2405&p=28600&hilit=veroboard#p25270
I used 1024MAK's circuit on my TS1000. It works beautifully!

This website abovementioned can test the TS1500/ZX Spectrum 16/48's inductors. I am trying to help all of you.

Not successful, bola_dor. I still need all of your help convincing Peter (ZXRenew) to do something to make us happy.

Re: TS1500 no video
Thanks, however, I meant the picture of the TS1000's ULA's, not TS1500. I plan to take one TS1500's ULA off its board anytime. I created a file of the TS1500 ULA's pinout somewhere around this forum. As for your TS1500's no video issue. 1. Try to lift a Zvid "small board" of the motherboard a little...

Re: TS1500 no video
Please take a picture of a ULA itself and post the picture here. If the ULA is lower than 2C210E then, ask 1024MAK for his help. He is a great gentleman who knows about the ZX81 / TS1000's ULAs history and its quirks!
I also am the owner of two running TS1500s. I live in the state of IN.

Re: TS1500 no video
Spinnetti, Take an inductor(L4) off the board and test the inductor with continuity range on your multimeter. It should be continuity on 2 legs of the inductor's sides. And also test the inductor with a piece of equipment that tests yokes and flyback transformers. Try to test diodes and resistors wi...

Re: TS1500 no video
Spinnetti, Are there any of the 4 electrolytic capacitors looking like some kind of cucumbers within the DC-DC converter circuitry? These capacitors might fail without your knowledge. Test these capacitors for ESR. I concurred with 1024MAK. I also quoted this sweet gentleman on these capacitors. Des...

CZ1500 (TS1500) reverse engineering?
Bola_dor,
Can you do reverse engineering on the CZ1500 and draw a schematic? Then post it here.
Thanks,

Re: No video output, could use some advice
That clock wave picture showed that it(Z80) and its clock circuit area are working right. I bet that 1024MAK noticed it also. Congratulations, grimmware!
