IngoQs attempt at messing up the H4

Post by IngoQ » Wed Oct 02, 2019 9:38 am

"I am doing what he does, only slower" :-)

So my first step is obtaining a 1040ST as part source. I was lucky and found a hopefully bargain at ebay, 20 Bucks for a VERY dirty one:

BUT the case looks intact, so at least this will give me a good case and some parts, after a lot of cleaning and probably retrobrighting... So lets see how that goes :)

Will examine it further at the weekend and let's see how far I go. But until now not bad for 20 EUR... :mrgreen:

Looks like someone found it in a field :)

Cool that it works, any surprises when you opened it up?
If it ain't broke, test it to Destruction.

Haven't opened it yet. Will do so tonight probably and give the case a nice soaking in soap over night then. The disk drive seems to be busted, makes funny noises, but haven't looked into it.

The case is dirty but on first examination completely intact, so that's definetely a win :)

Until know, the only thing missing is the ESC key ;)

There's not escape from this one.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Managed to sneak a little Atari time in today ;)

My guess is, this ST belonged to a musician because there are markings at the MIDI port, indicating IN and OUT.

When turning around to disassemble I noticed the intact warranty seal... so no big surprises inside ...

... besides loads of dirt ;)

Blitter seems to be integrated, so I guess I have to find one for the H4. What else am I missing for the build?

PSU seems to be a Mitsumi SR98:

So could probably recap it, or buy a nice one from Exxos :)

And lastly the floppy:

Its an Epson SMD400 with long button, currently not working. Lets see, what it is missing....

I put the case parts and keycaps in a nice bubble bath of soap and will let it soak over night.

So much for today ;)

Erm, that's a short button floppy, en Epsom SMD-480 with a strange "SMD-400" label. It's the last type of floppy fitted to the STFM line.

Believe me, I've got quite good at spotting the different floppies over the last couple of weeks! :D
