Some time ago I made a recording of our IBM System/36 model 5363 while IPLing. What makes that video stand from others is that I decided to record both the operator panel and the console screen at the same time by the means of a synchronized recording program. This way the complete process of IPL can be observed from both perspectives at the same time.

You can find the video over here.

I hope you enjoy it and, of course, I would like to know what do you think about this system and its 10 minute long boot process.

Thank you for your attention!

Hello,

I am the proud owner of a SAGA PBS-800 computer. It is a very good-looking computer and by looking at its internals, it looks like a high-end CP/M computer.

However, not that is good-looking has to be necessarily good. Its firmware only contains code to bootstrap from disk, and the disks seem to have been lost in time as well as have its manuals. So far it is a beautiful deadweight.

I have read through an old article that at some point this computer was also produced at Australia among other places, so I think it would be interesting to hear from Australian collectors. However, I would like to ask everybody regardless of his/her location if they have the data I am looking for, or could give me a hint on how to acquire it.

The alternative is a reverse-engineering process that will be long and costly in order to find the architecture of the machine and later, the modification of CP/M sources to make a tailored version for it.

So please, could you help me in my quest for data for this computer?

By the way, you may find dumps at bitsavers. Please, don't refer to them here as those are my own dumps.

Thank you very much in advance!

P.S. I am having trouble with the picture. Sorry for being a noob!

P.S. 2 For more pictures of this computer, you can check my website brief article for it. Note that once I study it I will have to rewrite it. (link)

Please read this first if you don't already have.

As I mentioned in the previous post, all devices connected to the ATA bus (both channel) got fried when i tried to overclock The Beige Beast. I've done some research since then, and I've found that all of the dead devices have chips that get super hot when power is applied.

Today I got to borrow a IR thermal camera, so I could see what was actually happening, and the results are interesting... This is when I only connected power, via a different power supply than that in the PC.

• The hard drive has only one chip reacting to power, but that one chip is becoming about 90 °C, which is obviously hotter than it should be. All other chips appear cool
• The ZIP drive has multiple chips heating up, including one resistor. The hottest gets around 70 °C.
• The first CD-Rom drive have a few chips get hot, including a resistor, a thing I assume is a voltage regulator, and the main chip. While the voltage regulator gets up to around 110 °C, the main chip got to a staggering 211 °C! Some other chips also "lit up", but not as hot as those.
• The second CD-Rom drive does show one sign of life; the LED light blinks when I press the eject button. On this, we have a cluster of resistors getting to around 80 °C, a transistor or something hitting 60 °C, the main chip hitting 55-60 °C, and a chip on the underside getting over 120 °C.

So something is definitely shorted in all of the devices. Keep in mind that these devices have no signs of life or activity other than the extreme heat from the selected chips. Any idea what could've happened?

Compaq Evo N600c

I recently got my hands on a Compaq Evo N600c. Overall, I’m quite happy with the device, but I discovered that it has a little sister, the N410c.

What I particularly like about the N600c:

• 1GHz Pentium III
• ATI Radeon 7500
• Sound Blaster-compatible sound chip
• Relatively bright display
• Fairly quiet operation
• Great keyboard

What I like less, but can still live with:

• Weight: about 2.2kg
• Display size: 14 inches

The N410c offers:

• 1.2GHz Pentium III
• ATI Radeon 7000 (or possibly a 7500? Not entirely sure)
• Sound Blaster-compatible sound chip
• 12-inch display (I just love small notebooks :-) )
• Lightweight at 1.6kg

Now I’m wondering: Is the display of the N410c also relatively bright? And is the device fairly quiet as well? Or is it relatively noisy due to its construction?

I’d be happy if an N410c owner could answer these questions for me.

Thanks!

Hello, I just got a 5150 the other day and while setting it up i remembered I got 2 ISA cards a while back. I’ll post a pic of the second one when I get a chance but I think it’s some sort of Canadian 16 bit sound card?

The more interesting one is this VGA card I found, I think it’s a Heath VGA card based of a eBay listing I found.

My main question is can I use this on the 5150? And if so can I use it with the mono monitor I have? Oh and when I post that sound card is that usable on the 5150 or is that to new?

Thanks for all the help again!

EDIT: Here is link to other card.

Looks like an Advanced Gravis Ultrasound?

Packing up the house I've lived in for 34 years . I've been finding all kinds of computer parts, software and whatnot. But this, this really tugged at the old heat strings. How many hours spent on my 386 DX 25 grinding hallways for secret doors and killing as many nazis as possible? I still have it installed on my old 386 laptop down in the basement.
