Retro Vintage Laptop Compaq SLT/286 MS DOS 6.22 Windows 3.1 New CMOS Battery!

This is a truly outstanding unit in excellent condition for its age with tasteful and modern "quality of life" modifications to make it more usable:

• A) The dreaded "Dallas dead clock battery" issue that typically plagues these units is FIXED! It has been modified so that there is a new, modern CR2032 CMOS battery holder fitted and easily accessible in the battery compartment. It holds date/time and settings without any issue.
• B) A modern barrel-connector power adapter has been fitted to the 6 pin power connector, so that you can use the included 18V power adapter.
• C) 2.5 inch hard disk drive has been fitted via an internal adapter (see photos for the tray pulled out showing the hard drive, which is secured to the plate with strong velcro). A total of approx 3GB is accessible in DOS, split across drives C and D (1.5GB each) - plenty of space! OnTrack Disk Manager was used to achieve this, in conjunction with selecting hard drive type 41 in the BIOS as noted by the stickers under the keyboard.

Installed / provided:

- MS DOS 6.22 and Windows 3.1 has been installed and there are some DOS games on the C drive, so it is ready for gaming out-of-the-box if you desire, or delete the C:\GAMES folder if of no use to you.

- The "cute mouse" generic DOS mouse driver has been loaded onto the machine for your convenience. If you have a serial mouse, connect it up, power it on and run CTMOUSE.EXE. A google search or two can provide you more instructions, or feel free to message me.

- Windows 3.1 basic PC speaker driver has been installed which gives some higher quality sounds (e.g. boot up "tada" sound, and shutdown sound).

- Included, free-of-charge and as a courtesy, is the SP0308 Compaq Diagnostics utility written to a 3.5 inch diskette incase you need it (but please see further below for a warning on this).

- 18V power adapter is included. Please note this is an adjustable one - do NOT adjust it to any other voltage or it will damage the SLT unit!

- Will come well packaged and postage insured up to the value of the item for your peace of mind. I can remove the insurance for discounted postage ($29.99 instead within Australia) if preferred, just let me know, or you may pick it up at no cost.

The following functions have been tested and work fully:

- Keyboard, serial port, PS/2 keyboard port, CRT/VGA port, floppy drive, CMOS battery, brightness and contrast controls and lid latches.

Please be aware of the following before purchasing:

- I could not test the printer port, parallel port or expansion breakout connector as I don't have the equipment to do so, so they may work or may not.

- The screen works fine, but there are some cosmetic scratches and some wear as expected given its age.

- As is common with these units, the keyboard cable sleeve is flaking off due to age. The keyboard still works 100%.

- As a free-of-charge courtesy I have written the SP0308 Compaq Diagnostics utility to a 3.5 inch diskette, incase you need it for future configuration changes. Please note I had no 720KB diskettes so I used a 1.4MB diskette with some sticky tape over the corner hole to trick it into thinking it is a 720KB diskette - do not remove it or it will not work! This is an old and common trick but more prone to failure long term than using a proper 720KB diskette. I strongly suggest you write the SP0308 utility onto a proper 720KB diskette long-term to ensure reliability. I can't guarantee how long this temporary trick will last.

- The standby button doesn't appear to do anything; this may be due to the main battery not being fitted, a driver missing, or something else.

Any questions please ask, thanks!
