PCs & Compatibles / Writing 5.25" disks
Last post by RuneRider - September 19, 2015, 10:08:21 am
Anyone have the rig to write 5.25" disks from image files?

I'll eventually set something up but need some disks written for a project and am stuck at the moment.

Thanks for any help you might offer.

Test and Bench Gear / Re: Anatek 25-2D Bench Supply
Last post by 10Sector - November 10, 2014, 02:52:29 pm
I've been picking away at the unit. So far just recapping the supply, and learning how it functions. I've aquired new power transistors, as 3 /4 were dead.

I got a bit hung up, as my boards don't match the schematic. It must be a later revision as it isn't based on the OP amp, but a MC1466L regulator chip. Once I figured that out, the boards made more sense, and I can use the MC1466L datasheets to troubleshoot the system.

So far, on channel 1, there is no 20v logic supply, and the power transistor was shorted (hence the 40v output)

I'm reverse engineering it, and building a new schematic for the MC1466L circuit boards.

I just picked one up at a hamfest, to go along with my dual 50V / 1A version.
Does this make me a collector?

Thanks for making the manual available.

Any luck getting your supply working?

Test and Bench Gear / Anatek 25-2D Bench Supply
Last post by 10Sector - August 06, 2014, 02:27:42 pm
I recently acquired an Anatek bench supply. Dual output, voltage and current limited, 0-25 Volts / 0-2 Amps.

A nice little unit from 1972, according to the stamp inside. It is a kind of hybrid switching/linear supply.

Channel 1 is completely dead, and channel 2 is stuck at 40 volts.

After a lot of searching, I found a scan of the manual with schematics (attached) to this message.

Gonna post as I get this unit repaired and powered up.

Hello, Didn't notice your reply.. Wouldn't the forum sent any email ?    Anyways.. Its basically just a project to be able to use machines we actually enjoy working on.. Currently the oldest machine I could locate was a 486 DX4/100   Which is great. Also have located a imac g4.  Really enjoy older machines mostly dos based usually involving some flavor of windows 3.1x. or older distributions of Linux, Novell Netware 3.12 and that sort of thing. The whole thing makes me regret machines I got rid of years ago that I seen no value in at the time.   

Not trying to plug my website but I also have a website that I'm working on.. retrodigital.net   has a bit more information regards to what i'm trying to accomplish.


Thanks for your reply
Mike

Anyone know anywhere to locate some of these machines.  Me and a friend are currently working on a retro pc project.  Please let me know if anyone has anything or knows where to locate it.   Calgary apparently is too quick at sending these wonderful machines to recyclers.


Thanks
Mike


I'm very curious what your retro pc project is about? My ancient PC hobby is taking a bit of a back seat at the moment.

I will pass on what your looking for to some others I know.

Cheers Joe

Sure, There is just one problem. I live in Calgary and you live somewhere north. Might have to mail it. PM me if you need it and you can do it. I am really in no hurry for it at all, I have been busy moderating on another Brony forum and minecraft server for the past bit so sorry for the delay.  :D


No, I'm in Calgary as well.
