The mid-80's Kaypro 2000 laptop was I think the only LCD laptop made by that company. Classic 80's design. This was a 8086 DOS-based system with a pop-up 3.5" drive. Click image for a few more photos.

A useful NTSC Commodore Plus/4?

by billdeg
Total messages in this thread: 1
A complete Commodore Plus/4 system with CM-141 display, joystick, box/manuals, and a 10-box set of software.
When you buy a Plus/4 system from Ebay, expect the "CPU" chip, the 8501R1 (or 7501R1), to be dead. The classic symptom will be a pattern of small orange horizontal dashes on the screen, and a failure to initialize into BASIC. I was fortunate to find a source for these chips, no longer available by the way, and fix the system you see here. The next obstacle one must overcome to making your Plus/4 system useful is to find software. Most of the Plus/4 software was written for the PAL version, and very little will work on an NTSC system. I have searched extensively and collected the "best of" programs for NT">... [ read more ]

The Compaq Portable 286 is one of the rarest Compaq portables, very few were made with "Compaq Portable 286" nameplate.
This system has a 10MB hard drive and came with Compaq DOS, the original manual, and an AST add-on card of some type. The system will overheat after a few minutes. I need to spend more time with this one to get it running properly. Photos">... [ read more ]

An 8086 Monitor for an S-100 Bus system

by monahan_z
Total messages in this thread: 1
I have been writing 8086 code for a fairly comprehensive 8086 monitor (~9000 lines of code) that with a number of new S-100 boards (an 8086 board, our IDE Board, our ZFDC board , our PIC-RTC Board and the Propeller driven Console IO board) allows one to boot MS-DOS. The goal is to have hardware and a BIOS so that standard generic MS-DOS (or FreeDOS) does not know it's not talking to a PC motherboard. This turned out to be more difficult than I thought. Most major PC software interrupts (0-20H) have to be emulated in very precise ways. Anyway delighted to say MS-DOS (V4.01) now boots up on 3.5" floppies or on a CF-Card with our IDE drive S-100 board. Thanks to this group BTW for suggesting NASM. Fantastic assembler If you have time take a look at http://s100computers...itor/8086%20Monitor.htm there are a few short videos there that show the">... [ read more ]
