Re: Thurnall Hardware Add-Ons

Spooky massive coincidence alert! I was sorting through some ZX81 paperwork and books earlier today to sort out a selection of spare German computer books to put on ebay and I re-discovered this: 20210727_211552.jpg I never actually had the device. This 8 page instruction sheet came with a German j...

Re: 512K flash memory internal upgrade - no traces cut

I did it all at the weekend. I went for the OZ 4.7.1 official public release instead of looking into the v5 yet. It'll still be a massive improvement. Mine is actually a German model with German k/b so great that the newer OZ versions lets you configure the k/b type. I programmed the SST flash chip ...

Re: 512K flash memory internal upgrade - no traces cut

Excellent clear write-up. I now have the required bits to do this to my Z88. The website with the OZ ROMs is probably the most confusing part! There is a read-me that explains the naming, but there are a lot listed, mostly development versions.

Wanted: Zilog Z80, week 17 1982

For originality (in an Issue 1 Spectrum as it happens) I'm looking for a 1982 Zilog branded Z80 that is as close as possible to week 17. Perhaps someone has a socketed one of that date in a ZX81.

Happy to swap for a newer Z80 or to pay a fair price.
