Re: A3010 hard disc interface

OK, I think I got it. Only two doubts. On the HCT14, on the schematic, gate 8-9 goes from *rst to 711 ¿? what's that? PDF does not allow search the document since there is no OCR on him. Second one, I don't find the ideled signal, im blind, jejeje. This is the actual looks of my humble interface. ht...

Re: A3010 hard disc interface

aranet - if you look at the schematic of the A3020, it's exactly that. The only difference is It picks up the address/data lines from the ROM sockets, additional data lines from the podule slot and the other signals onto pads with flying leads. Ok, i will make a schematic and post here so you guys ...

Re: A3010 hard disc interface

Any chance to obtain the schematics of the working board? I mean the design of Vectorlight or Munchausen.

Thanks and Regards.

Re: CMOS Battery Replacement Questions

you could use a supercapacitor in order to replace the battery. I fix two A30x0 by adding a little pcb with a cr2032 batt holder and a diode (since the CR2032 is not a rechargable battery) that I made for others systems like Amiga. https://i.kinja-img.com/gawker-media/image/upload/s--vZE2V-r7--/c_sc...

Re: Attempt to repair an A3010 IFEL 4Mbyte RAM upgrade

You could check if some of the two modules are wrong with others two ram modules, you need to bend the pins out and "piggyback" them to the current ram module on the little board. With that you could see what module is wrong. The cap us a common 47uf 35v smt capacitor. Like this one: EEHZA1V470P Reg...
