OK, anwser found on the wiki page, thanks! It should work...

Yes, but there are many versions of the pcb, this one is 3C509B-TPC and weird thing is that it has no socket for the ROM chip, the holes are filled with solder and there is a CY6264-70SNC SRAM chip next to it that shares the traces wit the ROM chip position, can it be that they used this chip …

I have this card, do you think I can solder a DIL 28 socket to those holes and use the XTIDE ROM? There is some SRAM chip on the same traces, is it possible that it's used instead of the ROM chip? Filename IMG_1624.jpg File size 1.59 MiB Views 209 views

Yes! It is the same card, but there are no tables on the silkscreen, so thank you very much! Also the bios really only tries to auto-detect C and D drive, the CD-ROM option is not there, but it works on the secondary channel fine with a DOS driver. But still I would like to use two HDDs in the …

Hi, i have an old 486DX2 80Mhz pc with TK 8287 2J D01.1 I/O controller ISA/VLB card, I would like to connect two HDDs and CD-ROM drive, HDDs on primary IDE are auto-detected by BIOS just fine, but whatever jumper settings I use, I get nothing on secondary IDE, weird thing is that CD-ROM drive on the …

Hi, I have an old 386 laptop from 1991, there is the DS1287 rtc with integrated battery that is completely dead. The HDD is 60MB Conner CP2064, I have found the parameters online, but when i try to enter them to BIOS and save it, the systen reboots and forgets the settings again... Is that possible? …

It is a dos help file, I was unable to open it with winhelp, but LIST.COM did the job! Thanks!

Hello, I have an old EPROM programmer, the software for it is dos based and the manual is saved in a .hlp file. I know that the help files in DOS are managed by HELP.COM. Anyone has an idea how to add hlp file to dos help database or how to load it with HELP.COM? Thanks, Lukas.

Thanks, I will give it a try. I didn't know about TH99, thanks for the tip! 😀

No, it is just three pins in a row, however there is a four pin header "J1" right next to it. I will chech the ground pin with multimeter, but I still need to figure out the positive pin, I guess it is not a good idea to apply voltage to some random pins. Yep, I have already cleaned the board with …

Hi! I recently acquired two old socket 3 motherboards and decided to build a childhood 486 system around them. Unfortunately one of the boards had the known battery leak problem and the traces from the battery were completely eaten, however the board has a external battery header, at least I believe …
