[ICD ST HARD DRIVE ADAPTER BD remake project finished]

I wish I still had the PCB that went in my SH205, because I would have sent it to you to make a SCSI substitute with. Will be building this though. You are providing a fantastic service to the community!

[Atari SH204 upgrade?]

The ACSI-SASI (yes, SASI) bridge that shipped in the SH204 will only work with the oldest of SCSI drives - nothing bigger than 80 megs in theory and nothing bigger than 40MB in practice. I've only gotten the tall-mech Quantum ProDrives to work and 10 years later they're starting to all die off because a piece of rubber inside the drive is melting into crude oil.

 

I never even tried the MFM drive on the MFM-SASI bridge that comes inside, just chucked all of it immediately. I don't F- with MFM. If you have to though, I hear this may work. Assembled, it's probably going to be more than a SatanDisk, but it's the only solution I know of with the potential to recover data from the MFM drive.

 

It may also be possible to configure a ZuluSCSI to work, but at that point you're also hurtling towards a SatanDisk budgetwise.

 

The SH204 is roomy enough inside to accommodate a different, better ACSI-SCSI bridge - thanks to t0ri it's possible to reproduce a number of them, only issue is finding the components and building them.

[New gold plated 5200 CX-5200 mylar replacements (Not from Best Elect.)]

this forum badly needs a bot that appropriately colors every occurrence of the word "gold".

[Vectrex shockboxes]

It's close, but the result there isn't going to look too much like a retail box.

 

And honestly, the boxes should have been plastic clamshells from the beginning, as they should have been for all consoles. IDK the Genesis, Master System, J-PCs, Neo-Geo etc. have spoiled me.

[Announcing the Super Game Controller for the ColecoVision]

This isn't happening is it

[Replacement Controller Membranes]

Intellivision 1 membranes appear to be out of stock everywhere now. (and II membranes were never produced)

[Vectrex shockboxes]

How come these don't exist? UGCs won't hold the overlays, but there's gotta be something out there that fits and could look good.

 

I found a place that will sell you repro cardboard boxes, but they only deal in the UK box variants.

[Definitive guide to burning 3DO games?]

The 3DO shares CD mechs and lasers with early (we're talking 2-4X) CD-ROM drives, mostly of the SCSI or MKE persuasion. They'll be Panasonic/Matsushita manufactured, or rebranded for OEM use (most of the SCSI ones will be branded as AppleCD 300i). Swapping is an option, but as mentioned earlier in this thread, even when these drives are working perfectly you'll need to be burning Taiyo Yudens on the oldest CD burner you can find at the slowest speed it will allow.

 

The MKE drives are sought after by 3DO Baster owners so that pretty much leaves the SCSI ones. If you find one in a Mac you need to stay intact you can just swap a newer one with a compatible faceplate (AppleCD 600i) or move the faceplate over since it's obviously not going to be of use in the 3DO.

[CV-NUC+ A Miniature CV Motherboard is in the Works]

Could you use a YMZ284 instead of a full AY-8910? That would really save on space provided there's a supply available.

[Colecovision 3D printable Controller]

By the way, it is possible to get injection-molded reproduction NES, Gameboy and even Game Gear buttons and d-pad pieces of any imaginable color from Handheld Legend. If you can get them to work in your controller that'd be fewer pieces that need to be printed.

[Colecovision Labels Thread]

I don't think anyone's come up with a label for Kevtris (the game, not the person) yet. There's no cover either!

[The perfect Intellivision controller would look like this:]

It has to do all these and fit into the controller wells to be perfect.

[7800 Pro- Missing pieces]

What sucks is that there's no formal name or manufacturer for these plugs that I know of, even though they were used on other equipment besides the 7800. Would help a lot in tracking replacements down.

 

I do know there's a version of it floating around with either an indent or no tab at the top, so that's something to watch out for.

[Need help with strange graphical glitch on CX-2600A]

I know but they went to all the trouble of making GIFs of the glitches and nobody responded. Gotta reward that level of effort on principle.

[7800 AV modding options?]

Bryan (or someone else) alluded to using 2 UAC boards to get stereo but nobody's done a diagram for it. I agree it's much easier to get audio out of the 2600 and 5200 with simple resistors and capacitors, and it can be done quite none-destructively too, but like the 400 the 7800 is a special case. It looks like it might be possible to do what's been done on the 2600 (isolate both TIA pins except for those "pull-up" resistors, add DC-blocking capacitors, run 1K resistors from both stereo halves to create a mono output for the mono pin on the video out connector and the RF modulator) but I'm not sure what to do with the cart sound input. I could run it to the stereo pins through a pair of 1K resistors again but I'm not sure if that's going to work or work well. Seems like most other consoles use op-amps to mix multiple audio sources internally. I guess I could try it out and see what happens.

 

I know that not all 2600 games were meant to have the two channels on different speakers, but the mod I typically do leaves the two channels mixed a little bit - they're not completely left and right but it's still noticeable.

[7800 AV modding options?]

There should be a way to get stereo out that has the POKEY audio mixed in. Bryan whipped up an audio amp board for the 400 that he said might be useful in other systems - would 7800 be one of those?

 

On 2600 stereo is easy since all you have to worry about are the TIA channels, and you can get softer stereo separation by using resistors to preserve the existing mono output. 7800 might call for an op-amp of some type. Maybe a design from another system could be adapted? I see an audio mixer for consolized Neo-Geo systems here that takes stereo and mono sources from the system's audio chip and mixes them to line level stereo. There's also one for NES that may support channel panning (documentation is unclear though).

[Need help with strange graphical glitch on CX-2600A]

Swap out the TIA for a known good one, see if the problem persists. Check internal voltages. Also try a different RIOT chip, though you usually can’t even get ingame when those go bad.

[A new controller SECOND BATCH AVAILABLE]

Will they fit into the controller wells on the INTV II? They look like they might.

[7800 Pro- Missing pieces]

The weird 2-pin connector IS used on other equipment, so what I've done in the past is get a cheap junk power brick that has the funky connector and then get another power brick that's openable and has the right voltage and swap the cable over.

[UAV Modification Wiring Schematic/Diagram for 2600 and 2600A]

On a previous 2600 I got away with taking the existing John Oliver mod and offering a mono output in addition to stereo by simply taking both left and right and joining them together with 1K resistors to make an additional mono output. This also had the desirable side effect of mixing the stereo channels slightly. Thing is, on that machine I was using an older board for video and throwing out the RF modulator entirely.

 

I'd like to be able to do this on another 2600 that I'm installing a UAV in, but I'd like to keep RF audio and the extra mono output if at all possible. Would I just be able to run the joined mono output back into the RF modulator and call it a day?

[Audio output from 2600 Light sixer - advice needed]

I keep forgetting PAL 2600s are mono only. The PAL TIA only has one audio pin.

[[RGB MOD] Help with some electronic components replacement]

The cap and the oscillator are easy to replace if you can get their values. The inductor you might have to splice some wires onto and move it a little out of the way. It's only used for RF so if you want to run without RF you can just get rid of it.

[Replacement Controller Membranes]

I'm not after "good" so much as I'm after "works at all". I also can't seem to find loose Intellivision Flashback controllers anymore. It used to be possible to just buy them new but not anymore I guess.

[Replacement Controller Membranes]

Any hope of Intellivision II controller membranes? Every single INTV II controller I've encountered has been in pretty bad shape.

[The Amiga Mini?]

I have a KTRL already, I'm just hoping that these pads will also be another choice since proper CD32 controllers are the way to go for all Amiga systems. Unfortunately even with the KTRL and the Amigakit pads they're still quite scarce.
