Thanks everyone ! I think the MCE2VGA may be my best alternative. Testing some older non-VGA stuff is going to be a problem very soon for me and need a simple easy to move around fix. One of the many cards I need to test is an old 1986 era GRX Legacy II which I can find no real good doc's on and …

My system consists of the following parts... Did you bench test the motheboard before assembling the computer ? Seriously the first mistake most make (even on Asus and Asrock forums with new hardware) is to assemble everything and then try to troubleshoot it. Being old hardware it is even more …

Cheapest decent XT KB I could find: https://www.ebay.com/itm/Vintage-Fujitsu-FKB4700-XT-Mechanical-Spring-Keyboard-N860-4700-T101/283280287283?hash=item41f4d22633:g:nU4AAOSwZNtb~d0D I would verify it is XT not AT before buying...

Thanks and good point ! the manual for it does list: CGA/EGA input signal auto scan (15K, 24K, 31KHz), but does not mention TTL. It does tell you how to connect a 9pin CGA/EGA cable to the inputs.... might have to call/email to see if really supports old school TTL EGA input. So is the 8219 also …

I am looking at getting a converter because my old NEC multi is slowly dying and really do not need a non-vga monitor except for testing purposes. The two am looking at are: https://www.amazon.com/Paddsun-Converter-Output-Monitor-GBS-8200/dp/B01IBJCAIG/ and build my on case and cable setup, or the …

It has no manuals for any of the motherboards being removed, and some have as many a 5 diff manuals in .pdf (product guide, ref guide, technical product spec, spec updates, etc). It also is missing all the index files to relate which of the odd numbered and named files go to what chipset or …

Thanks but are you sure that actuall has the manuals, BIOS, and drivers for all 250+ EOL motherboards ? Seems mighty small since I grabbed 1/2 the Manuals and BIOS only and it exceeds that amount. Ohh and no seeds on that torrent. A simple WGET will not grab things proper off Intel since they spread …

Hmm you don't have an old AT style KB that has the nice XT/AT switch on back laying around ? They work great for testing purposes. BTW picked up a Leading Edge DC-2014 xt KB for $5 at a thrift store a few months ago, was very clean and works great, not as nice as a model F but am not complaining 🤣

Wow Great of course most old boards will work if the MEM size is set larger than what is actually installed. Here is my edurcated guess for mem settings: JP1 : Parity, 1-2 = EN, 2-3 = DIS (is near BIOS chips) SW2: s1 thru s7 = size SW2: s8 = DRAM W/S (or speed). off = 70 - 120ns, on = 100 - 150ns …

Everything looks good. J7 is set correct. Are you sure you have the PS/2 port wired correct ? I have a pinout from Asus that shows their 6/8 pin PS2 port for most 486 and pentiums like this: 1 2 3 4 : 1 =Gnd, 2 = Data, 3 = NC, 4 =VCC, 5 = Clk, 8 =NC 0 0 0 0 0 - - 0 5 6 7 8

You can also leave as little RAM as you can and test single bank - if you stumble upon error - it contains bad chip - replace half of the chips with chips you removed... That is what I was going to suggest. Take all out but bank 0 and test, if passes then install bank 1 and test, etc. Also you …

Hopefully that will work, according to the manual for UM4981 AIO R2.1 the CMOS and RTC are located inside the UMC8498F main chip. You could also try shorting pins 2 & 3 on the ext. battery connector (with computer off and ext. battery disconected)..

checked a few manuals and the Shuttle HOT-553 has the Data and Clock (pins 1 and 5) swapped on the motherboard connector compared to the image Repo Man11 posted, the others pins are the same.
