A1000 and A1060 Sidecar Mods

[Jeff]

I just installed an NEC V20 cpu in my A1060 sidecar and it runs!
Nec V20 from Ebay Germany
The new CPU is rated at 10 mhz. Currently it is still running at the stock 4.77 mhz as I have not changed the clock crystal yet. It will be interesting to see if the side car will run at speeds close to 10 mhz. From what I have read the V20 is supposed to be 20 or 30 percent faster at the same clock speed although I haven't run any benchmarks yet.

I know it isn't a PPC, but kind of neat nevertheless. I wonder how many people have tried it?

@Everyone

Thanks for the information! It didn't even occur to me that the XT CPU and Bus run on the same clock oscillator. It is very old and running quite well. I won't even attempt to over clock the Bus.

I just need to sort out the hard card issue now and I'll leave it alone. I have an old 65 meg mfm hard card for it, but the bearings are so stiff in the HD that it blows the PS fuse every now and again when trying to spin up:-o  Time to look for another 8 bit controller I guess since mfm drives are extinct:-)
