made a series of little prom to eprom adapters.
It allows you to read proms (that can't be read or written with the standard eprom burners you find on ebay) .
So a 82s129/126 or 82s131 (or their other brands equivalents) can be read as or written to standard 27512/27256 (27128 should work too) eproms.
I've a couple of spare bare pcbs left from the first draft. I was going to throw them as the silk screen explaining the settings for 82s12x or 8s131 modes is inverted. not a big deal but I can't sell those so I thought I might give em to fellow boarders.
It's the bare pcb so you'll need sockets -16 pin to operate as prom reader, 28 pin to work as a eprom replacement, for the prom and eprom depending and pin headers.
I've 3 sets of each to give to 3 people. I don't think this warrants a ad but I can create one if it's an issue.

no worries. that's one set gone. 2 left
I'm also working on a series of jamma adapters and making some repro ICs at the moment. Starting with the Irem KNA chips , I should have the first protos next week.
Maybe I should make a pinned ad for all these in the marketplace ?0 -
hurray .. My KNA6034201 repro is a success !!
This is one of 4 KNA custom chips on an IREM Kung Fu Master (it's also used on R-Type) and my first attempt at making a repro IC. This specific one is known to fail often these days . It's similar to the one Caius from Jammarcade makes, my version is a wee bit fatter but offers nothing different. I didn't want to copy his version either so I used the original M62-G Sub board to replicate the schematics.
I'm working on the KNA6032601 next (using what was done on the bootleg as layout to trace the schematics)
but she looks pretty cool. proud day for me

...and finally , tested and working, a Generic Jamma fingerboard for making custom adapters for non jamma boards
My plan is to make custom adapter for various boards (starting with IREM classic, Capcom classic, 1942 and Sega system 16 to come... )
If that's ok with the other mods, I've placed an ad in the marketplace listing these and I'll keep adding more as I make them. I have the bare pcbs or fully assembled things at board.ie prices (people are asking crazy prices for these online)

YES! got the my second repro working. It took a while and a couple of wires to patch missed traces but I've a working repro for the KNA 6032601 IC (I got it wrong on the silk screen
) It is used for the final color attributions on IREM M57 (Tropical Angel) and M62 (Kung Fu Master, Lode Runner II, Spelunker, Little hero, Battle Road, Kid Niki, Horizon) boards.
Wasn't easy fitting 9 individual LS chips on a footprint the size of a z80 but I seemed to have found the one layout that worked with 4 on top and 5 on the underside.
I just need to order a final , all fixed, version and I'll add it to the list in the marketplace

I haven't posted these other than here and my FB/Twitter which is mostly people who follow the music channel so I haven't expected much interest yet
The first KNA repro has already been done by Caius so I've refrained from posting it on other forums and jammarcade.net although he said he'd be cool with it. I'm away most of june but I will post these on ukvac and other places when I come back for sure.
I'm working on some repro MSX and Veccy cart boards next, two more custom Ic repros to finish from the Kung Fu Master board then I'll prob move on that big sound module you see on Capcom boards like Ghost n Goblins and Trojan0 -
Not so much a repair but rather a new build...
(Couldn't find anywhere more appropriate to put this other than perhaps the MAME of Shame :P)
I presented an idea to the company that I work for a few months ago. We've moved into a new and improved building from the old place that we used to be in with dedicated gaming areas (Nintendo Switch, Xbox, Pool Tables, Air Hockey, Foosball etc). My proposition? If you fund the parts for an arcade machine... I will build you one in my spare time.
So... after many days working after hours this is the end result.
All that's left to do is tidy up some of the internal wiring, clean her up on the inside a little bit... mount some of the internal components correctly and get the power socket sorted out.
Really excited about this one. There's a "beer cart" event happening in our canteen later today too that I'm hoping to showcase her at.0 -

I know far too little about electronics to be doing some of the things I do tbh
There was a time where I was discharging a CRT monitor in just a nightgown while trying to stop one of my cats trying to climb into the back of the arcade machine where I paused and thought;
'You know what Oisin, you should probably read up a little more on the whole electronics thing'0 -

Argh, sat down last night to play some Gamecube games on my Wii. Wanted to give the new Gamecube controller I picked up a while ago a bash.
Fecking harddrive connected to the Wii starts beeping - totally borked!
Only bought it back in December but it seems to be out of warranty already. Opened it up to see if I could fix it but the heads were totally broken.
Was a Western Digital My Passport Ultra 1TB - you can only imagine the amount of game images now lost.
I think I'll need to get a harddrive that's a bit more heavy duty, those WD passports, while handy and all, don't really have any weight in them to sit beside a console.
What about something solid state? Should have a bit more resilience no? I'm using a flash drive in mine but also don't care too much if it stops working 0 -

How do you find games run from the SDD? Any issues?
I think I'll go that route next alright. Did see an interesting mod where someone removed the DVD drive completely and used the space to mount a HDD internally.0 -

That's been my experience and was the general consensus I saw online when I was looking for storage options.Retr0gamer wrote: »It's the same interface so SSD should be better and could mean shorter load times as well.
I should also say I'm thinking of the Wii U instead of the Wii. It's been too long since I dusted off the Wii to remember what differences they have, but definitely remember running games off an old USB thumb drive on the Wii 0 -
