I recently picked up this keyboard from a surplus place, and it has a DE25 connector. It has no brand name that I can find or anything else that would point to a manufacturer. I love the feel of the keyboard and would love to find a way to use it for projects.

My primary question is whether anyone can confirm if the connection is likely parallel or serial? (Or any other info about it) I'm guessing this is likely an "ascii" keyboard as they used to be called and the connection is likely parallel. (Basing that on the repeat keys and separated CR/LF keys.)

Then ultimately I'd like to find a way to use this with a modern linux setup so I'd love any tips on how to do that, even if potentially I need to wire in a keycode decoder of some time. The keyboard has a great feel, with two "locking" keys and just feels fun to type on. But determining where to start with the interface is the first piece.

I don't know what else to do, i would really like to see it working and build myself a retro system with a voodoo2+tnt2. Should i try to desolder the bios chip (it's not in a socket) then buy a t48 programmer, erase the chip, flash the most recent bios, solder a socket, put it in and hope it work?

Necro repair seems to check the board first with an oscilloscope, but i don't have either, i would love the try and get it working and learn, but 200$+ to maybe have a chance of it working seems a bit steep.

Hey guys, I would love some help on what these older HP machines are worth. It's a 82913A monitor, an 86B keyboard, a Think Jet model 2225A, And a 9121 (what looks to be a floppy disk reader). I'm not looking to sell these just what the value might be. Thanks for any help!

Don’t see those everyday!

Just got an idea for this, as I occasionally see computers and electronics that I think others would enjoy (eg windows xp machines) that I don't have the heart to allow being thrown out potentially, but not what I usually collect either. This could save a lot of stuff from the dump and help collectors not turn into hoarders.

Yes I know there is craigslist and the like out there, but a dedicated site and maybe forum can serve as a better hub for collectors and sellers or giveaway-ers. What's more, we can make such a site really basic, since we're all about old school stuff anyway. It'd be nostalgic in a sense. It can maybe eventually be THE go-to place that everyone knows and maybe thrift stores can profit off of too, and others who would throw these things out for trash or recycling. Just an idea, hope to inspire someone who would be interested in making and/or managing such a platform. Possibly off of donations or a cut of any profits from sold listings? Idk

*EDIT: no, I am not selling anything. I'm throwing an idea out there for others to see or be inspired.

I was a Data General NOVA programmer in 1969-71, and my employer purchased a head-per-track drum memory made by Alpha Digital Data Systems (pretty sure that's the correct name), which made my job a -lot- easier than dealing with paper tapes. (Note this was -before- DG offered any sort of operating system.) I haven't been able to find any info online for Alpha, and hoping someone remembers them and can point me in a good direction. TIA!

It was manufactured by the Kyiv plant "Kvazar". ROM capacity – 23 KB, RAM – 2 KB, expandable to 3.5 KB. The device could operate in calculator mode and in two programming modes: machine code (instruction set compatible with PDP-11) and a high-level language close to "Almir"/"Analytik". Weight – no more than 400 g, power consumption – no more than 0.7 W.

Structurally, the MK-72 consisted of two modules: a base module and an additional module. The base module was housed in a case and featured a keyboard, LED indicators, a buzzer, a 12-digit digital display, and a port through which the MK-72 could connect either to the additional module or to a small local network of up to 16 such microcomputers. The additional module provided video output to a TV, communication with a cassette tape recorder, a printer, or any other device connected via an 8-bit parallel port. It also contained additional 2 KB of RAM, of which 0.5 KB was used as video memory and 1.5 KB as operational memory. User programs or those loaded via the local network were intended to be stored on electrically erasable reprogrammable ROM.

The device's ROM was implemented on K745IK18 and K745PZU64K chips, RAM on K537RU3A chips, the CPU address processor – K745IK1809, the command interpreter – K745IK1810, the interface controller – K745IK1814, and the network expander – K745IK1817.

I'm hoping you all can help me find and get ahold of the parts I need to build a computer identical to our at least extremely close to the one I had as a kid. I've off and on searched for the parts over the years, but never did find anything. It was an Acros desktop computer(not a tower) 486dx2 66mhz, with a 3.5"drive and cd drive. I think i got 16Mbs ram in it though might have been only 12. The biggest thing I'm really wanting to get ahold of, was the cd drive it had. It was a 4x drive, but it was way different from almost any other drive I've ever seen. When you wanted to change the disc, you pushed on the whole front plate and the entire drive would click and then come mostly out. Not removable. Then you'd lift the lid and remove the cd. I know that Amiga had something similar, where you had the cd in a case, but this drive didn't use a case. You would just put the cd on the drive motor, close the lid and then push it closed until it clicked again (think computer desk cabinet door click). Thank you all.

Edit: the cd-rom did not come originally with the computer. It was added later. It was not a multi disc or caddy style drive. And I've corrected the post that the drive did not come completely out.

Edit#2: https://i.ebayimg.com/images/g/eecAAeSw7sJqRak1/s-l1200.webp here's a picture of a similar computer(though it might actually be the same). Though I could've sworn mine had a thicker blue stripe with the "acros" in silver on the blue. I might be mis-remembering though. So if anyone can confirm or dismiss my memory, that would be helpful too.

My retrospective video covering another Ocean Software movie game. This time it’s Hudson Hawk. I cover all the versions starting with the ZX Spectrum and then Commodore 64, Amstrad CPC, Amiga, Atari ST and also the console versions for the NES and Gameboy. Please share your thoughts and memories of this game. Is it a good game?

Thinking of upgrading my Cube to 64MB of RAM, which would mean buying 16 4MB 30-pin simms.

I'd like to buy newer simms made with two RAM chips, instead of the older simms with eight lower-density RAM chips.

Has anyone used the two-chip simms with a non-Turbo NeXT?

Greetings all. I've been here before in my journey to resurrect my IBM 9075 PCRadio, I've found the competent individuals who are presently raising it from the dead, currently dealing with a "Delaminated LCD panel"

So in the original packaging that I have with this device, there is an operations guide, which describes the function, capability, interaction and configuration of this device.. and it's worthy of a look..

There are a few of you out there who have enquired regarding this guide, & I've scanned and posted it to the internet archive & the submission is now public.

I hope it is worthy of your curiosity.

Rgds all

All,

Many here have helped me before, Ill see if anyone can help me out again. I have made a LOT of progress over the last few months since I got my Sun E3000 server. I love this server! It has been a great time setting things up and experiencing what this was like back in the early 2000's. I started my career as a java dev in a Govt shop which was a very IBM heavy agency but there was some Sun used here and there. My experience was mainly with IBM WebSphere but the Sun AppServer appears to be very similar at least in functionality. But, that isnt why I am here. I also installed the Sun Management Center using what is available on the internet archive. Sun Management Center 3.6 is available on the archive and that is what I went with...its the newest available and it works with Solaris 10. I got it installed and things are mostly working as you can see except the hardware integration. There is apparently a companion cd that went with the management center package that included the packages that would contain the hardware specific integration packages for the management center. After digging around (and asking ChatGPT...) here is what I need to find:

SUNWesmcf Metadata Config Reader

SUNWsycfd Sun Enterprise 3000-6500 Config Reader agent module

SUNWensfc English messages for Sun Enterprise Config Reader

SUNWessdr Sun Enterprise DR server properties

SUNWesadr Sun Enterprise DR module

These are the ones you can definitely see are missing in my install that are needed:

ERROR: information for "SUNWesmcf" was not found

ERROR: information for "SUNWsycfd" was not found

ERROR: information for "SUNWensfc" was not found

But I would like to find all of them. Does anyone know either where I could find the companion cd for management center 3.6, if anyone HAS the cd or image of it, or would be willing to sell or trade the package?
