Old computers

1701 error is something to do with the hdd or the hdd controller. The fact that is knows to try read the hdd as soon as the card is installed should mean that the controller is working, maybe the 35 year old hdd is dead or stuck.

I’ll see if I can take it apart and see if I can unstuck it.

I’ve had this IBM model M keyboard for a year or so but some random keys don’t work. 
 

Took it apart which involves cutting the plastic weld rivet things.

Thought it was probably a broken membrane trace.

I think this one on the edge is probably the problem, looks corroded. Tried a resistance reading and get nothing.

Maybe one of those conductive paint pens would work?

CnC. Yah. I gave a good customer a k6-2 600MHz with ISA slots I'd been hoarding because they had no spares for their ancient, horrifically expensive to replace pick and place machine.

The doofus factory manager of the day 6S'd it to the bin. Riiiight.

Holy shit the IBM 5155 hdd is working! All I had to do is take it apart, plug it in while open and give the head arm a bit of a nudge. 
 

20mb of glory. Some read failures but shit, it’s 35 years old!

 You're a brave man opening a drive like that. Have you ever had any problems with dust getting on the platters?

I’ve done it a couple of times and always ended up with a drive that started working when it was previously dead, so it not really brave it’s more like risking killing a dead thing.
There were no signs of life except for the controller card was working since it would indicate it was trying to read but failing.

I’m a bit stuck on the IBM 5155 memory expansion card and still waiting on the mouse for the 486 so I am now trying to revive a 386sx.
 

Yep the poverty spec one not the DX.

Have not been able to identify what the motherboard is.

I love the case on this thing, its a lot like the one we had in the early 90’s, metal lift up hinged top with two push in clips on the sides. But it has very little sign of life and  bios error beeps which indicate possibly a ram issue and video card as well.

I don’t have any spare ram to suit or an ISA video card that will fit. Nothing at the local computer recycling place and nothing on Trademe.

It did have a leaking cmos battery which corroded some traces but after cleaning it up and doing a continuity test it seems ok physically but still getting errors.

Either the monitor (monochrome) is stuffed or the video card is stuffed. It’s designed to output to a monochrome or CGA but it’s just a garbled mess of text.

Does anyone have some old ISA video cards they want to sell?54844B6A-988D-4AE2-9180-0C7615CF982A.jpeg.9394a956355fbd7b92b682f820c5c41e.jpeg12CC6840-B680-4AAC-B140-70BC75C47E4F.jpeg.2e8edf9aff6ff7fc10d7de525511f18f.jpegCF806C76-250A-443D-BF64-C625D41F264F.jpeg.4d41865114549c200c0845bd43a27c46.jpegC95F0251-6B49-4CDD-A7A9-321674DF2CF6.jpeg.6b71ebec349dd89cf6be64e38fe2ca59.jpeg

Have I got a deal for you!

Trident video card, and a 3dFX accelerator, and because it's you, a Coupl'a sound cards, for the price of postage. PM Deets

Also need to find a Serial Mouse... 

Would a PS/2 mouse get you there? Pics of I/O panel

(PS/2 introduced in 1987. Is my mouse oldschool, or is that only non-facelift versions?)

I found a local guy with a few bits so have a serial mouse and a generic vga card, its a pretty basic one but it should work. I am still keen to try out  those ISA cards though if you are still keen to post them. No worries if not.

Nah PS/2 is the small round plug that is still in use now (if not using usb mouse/keyboard), I needed the 9 pin D shaped plug (the crappy ball mouse ones that get gunked up wheels). From what I understand you can't just use a plug type adapter because of different voltages and protocol differences. Someone designed a converter board with adapter plugs which you have to flash firmware to just to get it to work, there are some for sale I think it was $65, might have even been USD? 

But I'm just doing this as a super low dollar hobby/time waster/not really sure why.
