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

James

Any PS/2 keyboard will do.

There is a proper service manual if you do a proper search for your model..

It could be a problem with the keyboard or the system board. Here's a copy of the Service & Maintenance Guide

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

That's ok 😀 😀

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

James

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.
