These pages are C Andy Welburn Just edited the brackets out of ifem 1 title So email link take you to the latest post – – – Updated – – – Yeh i’ve spent a tonne of inader on this pcb now, and while the cpu is able to trigger the sound properly, the ufo noise just doesn’t sound in-game which is very odd. Irem was founded in as ‘IPM Corp. Happy to give credit where it’s due.
Well done, I can sleep peacefully now. What would be the best way to share this file in a permanent manner? While looking into a recent repair, i noticed others asking about how to hook this game up, and that it seemed to be more common in Australia than elsewhere: Oh yeah, have a nice day: Now i’ve sent the pcb back to the owner and a full set of schems turns up!!!
I’d actually like to get hold of one of these pcbs for my own pcb collection, but i’d also like to hear from anyone else if their ufo noise is actually there?

So we need to find where these syncs come from, go get your pcb and look here: If you like this, like my page on facebook for more interesting and techy arcadey stuff! However after fixing all the sounds, and opm triggerign them in-circuit using my fluke they are all there, but the game code doesn’t appear to trigger the UFO noise at all, even though its there and works perfectly under cpu control.
Cheers Would you like me to mirror that on my site?
Good stuff, nice neat fix, hate to see boards with Sinclair-esque dead cockroach style fixes with chips splayed and spliced in. Without schematics, its a time sucker right now. Also, probably futile asking, but does anyone have the schematics for this pcb set?
I have replaced the PDF file with a much higher quality scan. This seems to have been quite well known in Australia, but i dont remember hearing or seeing any over here in the UK. Most space invader pcbs and clones suffer from missing sounds, and the pcb i have in front of me is no exception. Credit given on www. Known as the poor mans version of ” Space Invaders “. Also features a ‘coffee break’ between waves!
When dip switch settings are changed to advanced settings, the game becomes more difficult with the introduction of the UFO mystery score ship dropping ‘capsules’ that hatch into new invaders. Dropbox, SkyDrive, or Google Drive share.
The ‘coffee break’ is a unique feature in IPM Invaders whereas after every 3rd wave or pattern of invaders, the ‘coffee break’ appears. In they changed their corporate name to Irem Corp. OK – problem solved – I added you to my Dropbox and it downloded fine. If i can write to the address through the cpu socket, then thats all the game does when its running, so it should be one and the same.
Like most of their contemporaries, the company’s initial purpose was to produce and rent out electronic leisure machinery to various sections of the entertainment industry.
This isn’t the fault of the scan, that’s just what it’s like on the real document. To do this, we can join the NAND gate in the following manner to turn it into an inverter like this: Firstly, the pinout i found online was incorrect in a few areas, so i’ve copied and modified it so it is now accurate. I don’t use Acrobat – I use Foxit reader. Yeah who made it?
This would stand until the mids, when it would then be changed to ‘Innovations in Recreational Electronic Media’. Here is the file 13MB: What’s the ‘coffee break’? IPM Invader was a crude and shameless copycat of Taito’s milestone, but yet the sheer popularity of arcade rooms at the time saw the game do well enough to convince the company that games were a viable business opportunity.

You’ll notice that some of the writing on the schematics is barely legible. So far i’ve been going from experience and taito schems whcih help with circuit layout irem seems to have copied taito pretty much entirely on the audio circuits. My changes are in yellow: It’s possible it didn’t download properly, so it may be worth downloading it again. The place I worked at imported at least tables of these directly from Japan – they also got another type from Korea but the name escapes me Please chime in if you have any ideas regarding which boardset this manual was intended for.
Maybe the acrobat reader version you have is old?
