No more issues! It looks like it's a fully functional machine now. (OK, the keyboard switches bounce a bit, but are getting better. To begin with most didn't work at all. Mostly fixed with switch cleaner/lubricant + working them a lot.) I must admit that I've not tried loading a tape, but that can b...

It looks like it must have been a memory problem that the diag ROM doesn't pick up. I spent an hour swapping memory on one socket (fitted a sacrificial socket on top of the one on the board) and went through all the other memory chips I had, including a set of OKI 64Kb ones, and found all the chips ...

Did the TIP ever get replaced ??

I don't believe it was in the end.

However, I've been soak testing the machine with 32K programs and it's rock solid. It's been running the port of "Comic Bakery" non-stop for almost two hours now without a hitch.

I plan to do so too... and bring my slightly misbehaving resurrected MTX500 with me for some diagnosis at the clinic.

Ah, no. Leaving it to warm up and it's back to its old ways again.

I wonder if it's a problem with a capacitor.

Well, it's September and I'm back to the MTX... It looks like the GAL acted as a lightning rod and took all the damage. Phew! After I replaced that I have a working machine again. If anything, for some unknown reason it seems a little more stable than it did before with CP/M running for longer and m...

stty cols x works and the games are formatted correctly

the stty settings are transient though, I guess they need to be saved in some way

They would be. It's something to do with the console driver not reporting the screen size correctly I would imagine.

It looks like getty isn't setting up the rows and columns of the terminal.

You can set them manually using: 'stty rows 22 columns 39' (counting the characters on the screen in those photos to get the numbers).

I need to do some more reading, I thought that I would be able to run the programs when logged into the /usr/games directory, but it seems that I ned to run them from my home directory with the path specified I've always found it strange that MSDOS terminology for setting the current working direct...

Dave, Standard Unix / Linux / Fuzix / Raspbian :) Unlike Windows, the current directory is not (generally) in the path. Therefore if you want to run a file in the current directory you have to specify "./filename" not just "filename. That is a "dot" (for current directory), a "slash" (the path sepa...
