Firmware Simulation Of Diskette Data Via A Video Signal

View page
US Patent:
46316990, Dec 23, 1986
Filed:
Nov 30, 1982
Appl. No.:
6/445631
Inventors:
James C. Siwik - Nashua NH
Thomas L. Murray - Merrimack NH
Thomas O. Holtey - Newton MA
Assignee:
Honeywell Information Systems Inc. - Waltham MA
International Classification:
G06F 1100
US Classification:
364900
Abstract:
A data processing system includes a cathode ray tube (CRT) display subsystem and a floppy disk subsystem. The logic of both systems are verified by generating and transferring a fixed format stream of data bits from the CRT display subsystem to the floppy disk subsystem in modified frequency modulation (MFM) mode and checking the information received by the floppy disk subsystem against the original information presented to the CRT display subsystem. The bit rate of the data stream is varied depending on the number of address locations used in the data RAM of the CRT display subsystem to store each data bit.

US Patent:
46673296, May 19, 1987
Filed:
Nov 30, 1982
Appl. No.:
6/445608
Inventors:
Thomas L. Murray - Merrimack NH
James C. Siwik - Nashua NH
Thomas O. Holtey - Newton MA
Assignee:

Variable Loadable Character Generator

View page
US Patent:
47033223, Oct 27, 1987
Filed:
Jan 5, 1987
Appl. No.:
6/946663
Inventors:
Gary J. Goss - Acton MA
Thomas O. Holtey - Newton MA
James C. Siwik - Nashua NH
Assignee:
Honeywell Information Systems Inc. - Waltham MA
International Classification:
G09G 116
US Classification:
340750
Abstract:
A Loadable Character Generator whose operation can be changed to suit various needs, such as foreign language requirements, without hardware change and with minimum hardware. The character generator translates the character code of a character to be displayed to the dot pattern for that particular character, utilizing a minimum of hardware. The loadable character generator of the invention replaces the ROM/PROM by a RAM utilizing 2K and 8 RAM memories, a 4K by 8 memory, 4 MUX chips, and a Motorola 6845 CRT Controller with various registers and is loaded through the attribute buffer.
