Sorry to revive an old post - just checking whether you've had any luck in tracking down that board

Apologies for the necro post but, I also have an Olivetti M19 and if you want a copy of the Customer Test diskette, let me know (I should probably upload the entire batch to Archive.org). This was the first computer that my father bought for our household back in 1987 but, that computer (along...

I was visiting a friend the other day (who happens to have quite a large collection of different computers) when I noticed something interesting and was wondering whether anyone here might be able to verify whether my thoughts are correct. Attached are some pictures of case badges from two IBM...

Our very first (IBM PC compatible) computer in our household was an Olivetti M19. That PC has long since been given away. Last week, I managed to obtain another M19, with the full 640KB RAM and a 20 MB hard drive. Unfortunately, the hard drive isn't working anymore and the housing around the...

Does anyone perhaps recognise this old Western Digital MFM hard drive? There are no model numbers on this drive. I want to low level format the drive but, I need to know the model number so that I can try and obtain the settings for the drive if I want to dynamically configure it. Got this...

@hupshall, saw your post earlier but, only had time to respond now. I have the "Sperry HT" (which is actually another brand name for the Leading Edge Model M - the "M" standing for Mitsubishi). The Model D used Daewoo parts. I've attached the v4.71 BIOS from my Sperry XT.

@Unknown_K, I realise that this is quite an old thread but, is this perhaps your motherboard? If so, I do have the complete manual for this motherboard. This particular one is the Jetway J-402B.

I have an old CGA monitor that I need to calibrate. I'm looking for some old DOS based software that could perhaps display a test pattern or something similar on screen so that I can properly align the image. Must be able to run under DOS on an old XT PC

I've recently picked up this monitor from a friend of mine. At the rear it states that is was manufactured by Royal Information Electronics but, I'm not sure what the model number is or, what the exact specifications of the monitor is. I know that is a colour monitor but, I'm not sure whether it...

Thought I'd post some pictures of my motherboard. Strangely, on the board itself it's actually "printed" as being 64-256KB motherboard but, it's covered with a "sticker" (which has party come loose over the years). On the 256-640KB motherboard, are the wires at the bottom of the motherboard...

I recently acquired an IBM 5160 motherboard (that the seller sold as "non working") and I'm trying to see if I can bring it back to life. So far, I've ruled out the power supply (I used another one just to be sure), the voltage lines (tested the +5v, -5v, +12v & +12V with a multi meter and all...

The motherboard in this picture comes from the first PC that I bought for myself: It's a hybrid motherboard made by Jetway that caters for both 386 (including Cyrix DLC's) & 5v 486 CPU's. The motherboard model number is J-402B or J-402BG (not entirely sure which one). I'm hoping someone here...

I recently acquired this card: I found the jumper settings of a similar one here: http://arvutimuuseum.ee/th99/v/I-L/50442.htm Unfortunately, this one is not the same as my card (mine also has a couple of switches at the top (9 in total) that I have no idea what their function is). Does...

I recently came into possession of a Sperry HT (XT) PC. There are 8 sets of dip switches at the rear of the PC and then two more sets on the motherboard (over and above some jumpers as well). Attached a picture of the PC: Does anybody perhaps have a manual or information on what each of these...
