Re: zx spectrum in zx81 case

Has anyone built this board yet? I half way through and waiting for the remained or the components to arrive. McKloud mentioned some problems with the keyboard/diodes and a possible problem with the speaker damaging the transistor. Any other issues encountered? I have an Altera Max programmer, what ...

Re: Yet another ROM adapter

European guys, is there enough interest to buy the rest of Dans boards? I'm happy to front the cash and We could sort out distribution and costs when they get here? Update, I've been speaking to Dan as the link wasn't working for me. Result is I have bought 2 boards. Postage to UK is a very reasona...

Re: ZXmore - questions and answers (FAQ)

Hi, I've found a 4.7K resistor array at work and will put it in the board tonight and try the trick with ROM P2. If nothing happens, I'll get some photos taken of each side and send of the PCB them to you. Your offer to look at them is really appreciated, I just wanted to try and fix it myself first...

Re: ZXmore - questions and answers (FAQ)

Hello Karl I've desoldered the R1 array. Checked what was sent to me as a 4.7K array only to find its a 10K. Got some ordered but it will probably be Monday before it arrives. I've replaced that big inductor with the same one that's in the build document. You said to connect pin 2, but to where? I g...

Re: ZXmore - questions and answers (FAQ)

Hi Karl The resistor arrays are as follows: R1, R4 with the dot in the P1 position - towards the keyboard R2, R3, R5 with the dot in the P1 position - towards the edge connector. I think these are correct. Im still working my way through and ticking off the connections between ICs, this will at leas...
