Some of these are still available only from Jacquard. Through these devices, Jacquard acquired hardware design and production skills, thus becoming experienced in integrating 'pieces' into systems that worked, and worked well. These years of experience enabled Jacquard to design the first truly affordable and multi-functional small business system - the Jacquard Videocomputer... /media/museum/pubs/jacquard_j500_brochure_5.jpg title subtitle text image AMTEXT BROCHURE #1 /media/museum/pubs/jacquard_j100_amtext_1.jpg title subtitle text image AMTEXT BROCHURE #2 The brochure says:\ When you buy, lease or rent word processing equipment from AM Jacquard Systems, you get our total commitment, now and in the future, that assures the successful installation and operation of your AMtext word processing system. To support that commitment, we have offices in over 100 cities throughout North America staffed with skilled professionals ready to meet your neads with planning, training. supplies, and service... ...The AMtext 100 is a true shared resource, multifunction information system capable of supporting multiple work stations and peripherals simultaneously.

The AMtext product line includes a complete selection of peripheral devices, including telecommunications, an optical character reader. magnetic card reader, phototypesetters, daisy wheel printers. high-speed line and matrix printers, as well as mass storage on floppy and hard disk drive units. /media/museum/pubs/jacquard_j100_amtext_2.jpg 527 url date https://web.archive.org/web/20230208113648/http://www.old-computers.com/museum/computer.asp?c=527 2023-02-08

The Jacquard J100 and J500 Videocomputer line was developed at the home offices of Jacquard Systems, Inc. in Santa Monica, California. Development started in 1975 and by 1977 the first units of the J100 were installed.

The base unit included two 8" single-sided floppy drives and could be expanded to up to 14 users. The OS was Jacquard's own DOS. The CPU of the J100 was National Semiconductor's IMP16 microprocessor and the J500 - a follow-on single-user system - was implemented using the AMD Bit-slice technology CPU architecture. The J500, thus a multifunction monopost system, could be used for wordprocessing, mass-mailing, accountancy or stock control.

The J505 version featured the same motherboard plus a piggyback that allowed 2 additional terminals to be connected.

The AM Jacquard J-500 was composed of a central unit keyboard/monitor and two disk-drives. From 1 to 4 optional hard-disks could be added. The hard drives were the Pertec 14" with (I think) 10MB fixed and 5MB removable ans also the Control Data 14" 80MB drive.

The parallel printer port was a 12-bit port, unlike the standard 8-bit Centronics. The Xerox Diablo 1640 daisy wheel printer could be attached to it as well as many other printers.

The J500 was unique at its time because all of the CPU and ALU was stored and executed from a bank of 32 Proms (Programable Read Only Memory). The J100 could actually handle 64 interupts.This included stations and printers. It was limited to 16 because of hashing.

Display was performed by the same ROM/microcode/ALU that provided the main processing, timesliced in alternate 'quads' - 4 microcode instructions per process cycle.
