I picked up a DECmate III at VCF East consignment, and tested it with David Gesswein's DECmate II monitor/keyboard. I don't have the monitor/keyboard myself, but I _do_ have a working VT330 that I use with my PiDP-11. Is there a disk image out there configured to let me use my VT330 as the...

And as far as I can tell, this is what is supposed to be the pinout of a Microsoft Serial Mouse (Female DB-9): 5 4 3 2 1 (GND) ( ) (TxD) (RxD) ( ) ( ) ( ) (RTS) ( ) 9 8 7 6 When I try...

I have a working Microsoft serial mouse that I have successfully tested on my 5155. I have a PCjr. I made a DB-9 adapter for the RS-232 serial port on the PCjr. I plug my mouse in, and the Microsoft Mouse driver recognizes it, mouse test software indicates that it can register left and right...

I've been trying to install a SoundBlaster Pro card in my PC-AT (5170), but I have been running into some issues. All of the SoundBlaster-provided DOS test applications work, as do their Windows applications (specifically, their MIDI jukebox), but I can't get Jill of the Jungle or King's Quest...

I appreciate the VM/SP Quick Reference ;-)

I've had an extremely hard time sourcing SIMMs that actually work with the IBM EMEA. So far, the only ones that I can get to work in it are the ones that happened to be on the board when it got shipped to me from Ebay. I have no idea why this is the case, perhaps its some kind of a timing issue?

I've got a Model F keyboard for my PC/AT that I had to take apart to service, and its been giving me no end of grief putting it back together. I must have put this thing back together half a dozen times by now, and each time it gives me some sort of keyboard error. Currently, it is giving me a...

I've got an EP-1 and am trying to figure out how to use the thing. Is there a way to write EEPROMs to this from Linux using a serial adapter? If not, is there a PC-AT compatible version of the software floating around?

Well crap. What would you recommend using to clean it off the rails so that I can relube it with the proper stuff?

I have an Apple II Plus with a replacement (//e) PSU installed in it (Dynacomp model). About two months back, I started having power problems that manifested in a dim screen and the disk drive not having enough juice to run the stepper motor. Not knowing what I'm doing, I purchased a recap kit...

How were you able to lube the spindle bearing? I couldn't figure out how to disassemble it, or if doing so was even possible.

I'm posting this here because my particular Kraft joystick is the stock one for a PCjr. It hasn't been used in ??? years, and just plugging it in and trying it out shows that it isn't registering downward direction data. I had two more Kraft joysticks (one still new in box), and got similar...

Thanks for all the help, folks! I have still been having intermittent problems reading disks. For example, sometimes the DOS 2.1 boot disk I made was giving me "bad config.sys" errors, and sometimes not. I put DI on that disk and made a batch file that ran DI A: \N \B in an infinite loop. I...

I started work on a PCjr at the March VCF East repair workshop, and have been running into some issues with the floppy drive. I have been having intermittent problems with it playing a game, and suspect a possible drive issue. I'll presently describe what I did and what I observed, and would...

Long story short, I can't get mTCP to recognize the NDIS packet driver shim that appears to be correctly installing in my MS-DOS 5 based 5170. Read on for details... I have an Ungermann-Bass NIUpc/EOTP card and am trying to get a packet driver working for it so that I can use mTCP. I cannot...
