Re: Compaq Floppy/Printer board?
http://minuszerodegrees.net/rtc/rtc.htm The Quadram SETCLOCK.COM should be included in the Quadmaster software. The rest of the QM package is ramdisk, print spooler, etc. SETCLOCK in Autoexec.bat should fetch the time for the computer. SETCLOCK MM-DD-YY HH:MM should set the clock. Notice the lack of acknowledgement of Y2K in the 1980s.

Need to know by Sunday. One of the early Compaq ones. 360K. Although while that board was current, the PC-DOS format was 160K, followed by 320K. You can do 720K, of course. TWO drives.I thought that I remembered a version of it with a DC37 for external drives, but I might have put in a 5150 board for that. Has a real NEC 765 chip. It is unlikely to be able to do FM nor 128 byte per sector MFM, and has a nice long blind spot after indes pulse (making some complications with reading the first sector of track of some formats)

It is 384K RAM (what was needed to bring 256K up to the 640K maximum), SINGLE serial port, parallel port, joystick, and clock. It was made by Quadram, launching their "Quadboard" product line. Used to have a few, but it was easier to GOOGLE the info: http://www.computinghistory.org.uk/det/26768/Quadram-Quadboard/ http://www.computinghistory.org.uk/userdata/files/quadboard_operation_manual.pdf has switch and jumper settings. Download a copy and nail it to the board. Software to set the clock should be somewhere on the web. I don't think that ASTCLOCK is compatible. Serial, parallel, joystick, and RAM are compatible with the IBM ones. Quadram competed directly with AST in making multi-function boards for PC/XT. After a while, they started including a disk with a RAMDISK program (like VDISK.SYS) and a print spooler. They counted those as "functions" of the board, so that they could call a 5 function board "7 function", etc. I think that AST did likewise. "9 of the most-needed IBM PC functions" count 'em Quadram also eventually made the QUADLINK board. It was a complete Apple2 on an ISA board, letting you have an Apple in your PC. The Quadlink had some serious QC problems. The college bought a LOT of them, because some non-computer departments insisted that Apple2 was the only kind of computer that they could use. At least a third of them were DOA. Some had connectors wired backwards, so that thekeyed cables could not have been used, and had NOT been tested before shipment. When the DOA boards were sent back for replacement, half the replacements (which "have each been individually tested") were also DOA, including some with connectors wrong, so that they could NOT have been "individually tested". "Diamond Trakstar 128" was a competing product that was briefly sold through Radio Shack. Other than the Quadlink, the other Quadram boards tended to be decent quality. And, NO, thank you, I don't have any use for one. -- Grumpy Ol' Fred ci...@xenosoft.com

Hi all, I found this while throwing away e-waste at my old place: https://photos.app.goo.gl/R8xUxYijf1AYHNB38 Is it of any use to anyone? Need to know by Sunday. Thanks!
