  1. Wife thinks I am mad

    So the PSU of the MZ-80K has been reunited with the computer and it works. Monitor is clear and bright with no screen burn. The rest of the computer on the other hand is filthy. The keyboard keys are sticking and some of the graphic keys have labels under the plastic covers, obviously to represent a numeric keypad for some program.

    Keyboard has now been stripped, this required desoldering of every keyswitch, but after that they pop out of the frame as easy as anything and the keytops ...

  2. Further adventures of Multibus

    Finally got my 286/10 processor running in my multibus rack.

    I wire wrapped a iLBX bus between the CPU and memory cards but it wasn't starting on power up. In the end it wasn't getting a clean reset so I have now wired up a toggle switch to the Multibus master reset line and now it starts with a memory check (i think, it gives a row of 0 0 0) then the intel monitor program welcome message).

    Next issue is software. Not sure if I will program it myself with a simple OS, ...

  3. 5160 rides again

    The 5160 has been restored to good health.

    The case has finally been filled and sprayed. Pantone 413U seems to be a reasonable match, it has that greenish tinge but seems quite a bit lighter, however after sanding down the case it became apparent that the original paint was very very dirty so it might be spot against a new machine. For the bezel I used some BMW mini pepper white spray and that looks reasonable too.
    Due to the extensive damage to the metal case, it lost a lot of ...

  4. Projects building up again.

    A couple of months ago, I was worried that I was running out of projects, not now.

    My XT 5160 is a bit battered, but the bezel is glued back together and the case has been hammered back into about the right shape. Just need some car body filler to remove the surface defects then it will be time to paint. Not sure how to make the splatter, might experiment with nozzle modification of rattle cans. Reading up, a nozzle fitted with a short straw can be used to create a splatter.

  5. World of IBM, Intel multibus plus a new PDP 11 !

    My PCW9512 is sort of working and the Gotek is installed and was at a bit of a loss what to do next

    I managed to obtain a rack mount Micro PDP-11/73 that will need some care before powering up, but also saw a basket case 5160 on Ebay that was near enough to go and pickup, so went for it and now its mine

    The front bezel is split in two and the case is bent on the right hand side, just where the Hard Disk is , so that unit is very suspect, but hey ho.
