🤣

I never realized just how much like a young child the powerglove kid sounds, I guess I haven't seen that movie in quite a while.

Splurged a little on a keyboard I've wanted for quite some time:

1st gen IBM Enhanced 'Model M', more specifically the XT version - no lock LEDs. Apart from its weight (closer to an F than a later M) the really interesting bit is that it autosenses XT/AT, so can be plugged into a DIN->PS/2 passive adapter and an active PS/2 -> USB adapter and connected to a modern system. Like the one I'm typing on now.

Wow, you're out of control .... and ALT... ooops. Though out of my n specimens of Model M I'm probably down to n-1 complete sets of keycaps one way or another... they pop off easy when you don't want them to... check your packaging before it's gone though in case shipping knocked those off.

For my Ultimate 1993 IBM PS/2 486 computer.

Is that an M2 keyboard ?

I almost give up looking for one locally, then I found an ad with it. About 115 euro/125 usd shipped. Not cheap, but still not ebay price.

Is that one of those, you'd be happy to check and change battery in?

Nice catch!

Found this Sound Blaster ViBRA-16 (CT2260) in an old machine. It has an OPL3 chip, Line Out and Speaker Out. CD-ROM headers for Creative, Panasonic, Mitsumi and Sony. It also has a wavetable header. Usually the ViBRA-16’s I find don’t have an OPL3 chip so pretty happy this one does. Not sure if this particular revision has the midi bug. Will do some testing.

The MT-32 doesn't have a battery, so there is nothing to worry about in that regard.

Thanks for the heads-up! So there is no sense to open it...

Anyway, the unit is in great condition. It doesn't have even the smallest scratch. It is only a little bit shiny right near by the volume knob.
The only downside is, that the power supply is not the original from Roland.
PS: it's the older model without the headphone jack

You can still buy the Roland power adapter. They are a little more expensive than an eBay one but I’d prefer to know the unit is getting clean power. The model is a Roland PSA-120S (assuming you are in the US. There are also European and Australian versions). Most music stores will stock them.

Is 9.26 Volts too much for 9 V rated power supply? Measured without a load. I don't think so... bit I'm not a specialist.

YEA.... That's a load of kangaroo shit, mate.

The "adapter" is nothing more a simple transformer and bridge rectum-fryer. it does NOTHING for "clean" power.

The internal 7805 regulator does all the heavy lifting for the unit. These chips have been in production since the Apolo program put people on the moon. You just don't have an electronics part that is so very universal across the globe for 60+ years if its a "bad" device.

that said... when I opened my mt-32 and replaced the 7805 that popped when someone (before me) used a center positive supply, i did drop in a "new" meanwell unit: https://www.mouser.com/ProductDetail/MEAN-WEL … wc0Hd9eoQ%3D%3D

I plan to modify the jack to be the "standard" way around, but just haven't gotten around to it.

thats normal for a un-regulated unit. the 7805 is a linear regulator. anything beyond 5v is just turned into heat. thats how the 7805 works.

I would never use those old ass original PSUs, first they barely deliver the right amount of voltage, second some of the components in them are so old that the voltage output is totally out of whack hence hurting the device.
I have 2 OG MT-32 old and new and i use new PSUs, filtered and with a higher amperage than needed, having more amps never ever hurts, it keeps the PSU cooler and power delivery more stable.

A few pickups in the last couple weeks. Including an MT-32. Never thought I'd actually find one.

Also came with the original power adapter and a bunch of patch cables. Seems to be a really early unit with the 1.0.4 firmware. I thought I'd be able to put the 1.0.7 firmware on some 28c256 chips, but it wouldn't work. Might need to grab a couple 27c256 and a UV eraser and give it another try.

These were part of a big lot of stuff including a mountain of DIMMs, CD/DVD drives, and 3.5" floppy drives. There was also a bunch of ATX PSUs, but only half of them seemed to be decent quality. And about 10 P4 boards that are all pretty mediocre.

But still, these four P3 boards are enough to justify the purchase. P3B-F w/ 600MHz P3, TUSL2-C w/ 1GHz P3, P3V133 w/ 667MHz P3, and P2-99 w/ 450MHz P3.

I had already wanted to get my hands on a P3B-F and a TUSL2-C, so that's great. And I hadn't even heard of the other two before now, but they seem to be worth fiddling with as well.

And of course, now I really want a Tualatin 1.4GHz CPU, but they seem to be annoyingly expensive. I feel I must be patient, but patience gets really annoying sometimes. 😀

Wow, that might be the cleanest MT32 i've ever seen 😱
Great find! Mine is really beat up compared to this one 😆

Me neither! I was looking for one locally for more then 5 years and last week finally one popped up and I grabbed it!
Hey, but yours is a nice find! A boxed unit with manual and stuff... wooow

I wont a battle against a gold-scrapper! I also know ebay links are taboo, but I dont care: https://www.ebay.com/itm/235627579658

It is indeed a very clean and well preserved unit, but take a look at the other one posted on this page... boxed wit docs... 😀 That is a really nice find too!

That's not correct, the original power bricks of Roland modules are very simple, consisting of a large transformer, rectifying diodes and a capacitor. This generates the 9VDC input voltage that doesn't need to be too precise since it is then regulated down to 5V by the 7805 inside the module, as luckybob explained above. It's a classic linear design, and even though it requires a huge transformer and is not very efficient, it should produce cleaner power than a switching power supply. By using a modern switching PSU you don't gain any noticeable advantages, you may be even introducing more noise than with the original.

Switching PSUs are used because of size and efficiency reasons, so for things that need like 100W or more of power they are the most logical solution. But for low power stuff like these Roland modules a simple linear PSU is as good (or maybe even better) than a switching one.

Note that I use the modern Roland switching adapters myself, purely for convenience since the original PSUs of my modules are from Japan so they need a 100VAC input and I live in a 220V country, so it's much simpler to use the small modern brick instead of adding another step down transformer to the mix.
