ARDUINO SDCARD / POLYDOS

[bluebell12]

Hi Neil,

Earlier this month I remembered the box in the loft containing the Nascom 2, Memory Card & AVC that my Dad bought for us 40+ years ago. I doubt it had been powered up since the mid-80s when the BBC micro and then IBM PC arrived. Unsurprisingly it did not work but I am well on the way to getting the main board operational - a few 74 devices were not working and the video and IO PROMs were dead (just waiting for some replacements to program). Amazing how much I can remember about the NASCOM after so long! And surprised to find so many other people who have some enthusiasm for it.

While I was waiting for parts I was thinking about building a solid-state store based on a Netduino that I had lying around but then I stumbled on your Arduino / POLYDOS solution. I noticed that you say you might have a spare PCB and could supply the POLYDOS EPROM. I would like to get hold of these if possible. Also after a NASSYS3 ROM. I can get loan of a DATAMAN 48PRO which I will use to blow the Video and IO PROMS so could do the EPROMs myself at the same time if necessary. Happy to send parts / transfer money in whatever combination works best.

Thanks for any help you can provide.

Dave and I communicated and I supplied a PCB, closing.
