Re: New to repairing ZX's

Your second one has a quite early ULA at 8106. Nice. As most of the chips are socketed you could try swapping them around and may get a working zeddy. Thanks, but I'd rather repair them both. Gotta keep these 8bit machines running! I keep buying BBC's as 'spares' machines. But so far I've managed t...

Re: Hello!

Welcome on board!
To be a bit controversial I quite like the Apple II and have a Europlus I am in the process of getting usable. I used to go round a friends house and play Bard’s Tale and Wizardry on one a lifetime ago so its a nostalgia thing. :D

Re: Maxduino or Tzxduino firmware for a ZX81?

I have bought several of these from the same seller. I have the MaxDuino firmware installed - as well as working with the ZX81 it also works with my Oric 1, among others. I guess if you only ever intend to use it with the ZX81 it doesn’t matter too much? Bit more info here: https://www.sinclairzxwor...

Re: Spectrum+ 128K ToastracK RAM faults?

The built in Retroleum checks didn’t report any errors.

Neither did the Brendan Alford tests this time...

I will let it run in soak test mode for a while to see if needs to warm up a bit before it reports errors.

Edit: Update - 30 iterations without error. So most likely a dirty connection.

Re: Spectrum+ 128K ToastracK RAM faults?

Thanks. I didn’t swap any RAM between checks. I’m using a Retroleum Smartcard which boots to the diagnostic software shown. I can try it on another Spectrum to make sure it is still ok but only have a 48K rubber key so not sure it would be a worthwhile test? The Smartcard was fine a week ago when I ...

Spectrum+ 128K ToastracK RAM faults?

My troubled Toastrack strikes again! I decided to run a diagnostic soak test and got the attached. Interestingly different chips are shown each time. Does this likely mean: 1) The diagnostic software isn’t sure? 2) They are all faulty? 3) Something else is making them look faulty? I have no major is...

Re: Spectrum+ 128K Toastrack composite out

Well, gave it a go and it has improved the main menu significantly but Manic Miner still looks like a 3 year old added the colour to the screen with a medium sized paint brush! Although that is an improvement on how it was (2 year old with large paint brush) it is still pretty poor.

Looks interesting. I keep meaning to have a go at doing one of those.
