Hello

I'am new here 😀 Hello 😀

I Just bought a Compaq 4/25S Prolinea on "an online auction site"

It has a 304 keyboard error code.

It has yet to be delivered to me BUT

If i could Know what i need to do to get it working it will put me ahead of the game.

I purchased it to play games from the very early 1990's 😀

It has a 486 25 SX cpu and an empty socket next door

It also has a 3 isa riser card.

That is all i know about it thus far.

I am buying a new 3.6v battery for the bios and i have a varible temperature solder iron

Any advice or help is very welcome

Welcome. Replace the keyboard for another one PS/2 keyboard and see what happens.

304 is the keyboard has crapped itself.

Download the service manual pdf and read it before your system turns up...

There's a glitch in the matrix.

Apparently 32-bit is dead and nobody likes P4s.

Thankyou For Your replay Caluser2000.

Do you recommend a specific brand/model ?

I Do not yet know if the Original Bios Battery has become incontinent and leaked its contents all over the keyboard circuits.

As i dont yet own it i do not yet know which subcode it is.

I have downloaded a Manual of sorts and there are 5 maybe 6 versions of the 304 code 🤣 😀

Thanks again

Any PS/2 keyboard will do.

Wait till the PC arrives, Plug in a PS2 keyboard and see whats what.
No point trouble shooting something that's not turned up yet! but once it has we'll be happy to help

Hello 😀

So i have it now.

The battery has leaked near the keyboard port.

I have ordered some "concentrated vinegar" i will clean the whole board with it with a toothbrush.

It turns on and the hdd and floppy post. but it gets stuck on kb error.

I have found a replacement board on ebay if i cannot get this working from "solentspares" they seem to have loads of compaq parts of this era.

I have also bought 2 16mb memory modules. a windows 95cd and boot disk. though im thinking i might get windows 3.11 and try that first.

There is no cd rom drive 🤣, should i use something of the time (4x ? or 8x speed)

Thanks

If you take photo's of the motherboard members here will be able to tell how bad the motherboard is should you want to attempt to fix it.
I've purchased a number of things off solentspares number of times. I'd say they ask good honest price, not the cheapest but its a proper business with overheads so I'm ok with that.

Problem with 4x or 8x CD drive is reliability as they will be 20+ years old. Your probably better off getting a newer drive. DVD , burner doesn't matter as long s its IDE.
If you want to keep period correct that's fine. Majority of 486 games don't make have use of the CD drive, Redbook audio mostly and that's just a case of slow and steady 1x

Win95 will be pretty slow on 25Mhz, although on a 486 Windows is mainly for file management and 95 is easier to work with then 3.x
Dos/Windows 3x is a better match IMHO but again you'll be spending most the time in dos. It's just nice to have a GUI to copy files around the hard drive

I'm parting out a Prolinea of this model, could you link me to that page? I'm curious what this goes for.

I Quite agree with you. 95 will be slow. I have found an overdrive processor that iam going to purchase to boost it.

I will take some pictures tomorrow please keep an eye out for my reply.
