It was and is still an awful calculater/computer. It was the first one I owned. I''m still owning it. And sometimes I use it. - author: Gabriele Ruffini (Italia) date: Sunday 2nd January 2022 text: Hi I am a process engineer, during university studies I had a pb 200 and then axpb 1000. I wrote many incredible calculation codes and I suppose I surclassed all owners of hp48. The pb 1000 was really well built and optimized after the experience of the previous casio pocket pc., I really loved it - author: Per Wallgren (Sweden) date: Tuesday 4th November 2014 text: |- I really liked my PB-1000. I loved to make programs on the calculators. And the PB-1000 was the only one that you could program in assembly. I bought it in them middle of the 80''s and have it still with the disk drive MD-100. And still working!\ One of the best calculators ever made! :) - author: ElCrack! (Ecuador) date: Saturday 2nd November 2013 text: I really fell in love with my PB-1000. Bought it some time in the early 80''s. Used it all the time in university. Wrote countless programs on it for different purposes all the way from mathematics, physics, engineering and digital communications, to games, word processing and graphics. Still works! - author: Fermin (Houston USA) date: Thursday 10th May 2012 text: This was my first real Computer acquired at high school in 1989- 1995. served Extremelly well during university. Learned numerical methods with it, did Vectors and matrix programs that only can be done using a PC at its time. Still keep it but in a storage overseas. - author: Luis A. Molina (Ecuador) date: Thursday 12th January 2012 text: Bought one ca. 1987, used it through 1992. Helped me get through University, used it to solve fifth degree equations, generate tables, solve defined integrals, as a notepad, icebreaker with girls and after finishing formal schooling as an alarm clock. Died on me the day I graduated as a MSC. I''ve had a good 20 or so computers, handhelds, iPads, etc. since 1981, this has been the most admired and most useful machine I''ve ever possessed! - author: Terry (Qatar) date: Wednesday 17th August 2011 text: |- Had one of these in the UK. Printer and Disk Drive Unit. Used to cart it round in jacket pocket on construction site. Log instructions and comments as simple notes. Interface to PC was written via cable. Then used PC to produce the letters from the notes. Designed multi-storey buildings with 2D frame programme on the machine. Used to do little coloured ghant charts for construction programs for segments of work to allow people on site to follow. Touch screen for input. Years and years ahead of IPad. It just didn''t have the phone and colour graphics on screen. Could print four colours with the little pens. Fantastic bit of kit well ahead of its time. Was always amused it was Japanese but assembly and basic language where English. Lasted for years. Cheers - author: Terry (Qatar) date: Wednesday 17th August 2011 text: |- Had one of these in the UK.

On top of its standard QWERTY keyboard, a row of sensitive keys allowed fast scientific calculations, menus access and text editing. The 4-line LCD display also had 16 sensitive areas. The computer could be programmed either in Basic or Assembly language. The C61 Basic interpreter, based on Japan Industrial Standard BASIC, had a wide range of built-in mathematic, trigonometric and statistic functions. Assembly programs had to be typed by using the built-in editor then compiled. The user's manual gave little information about CPU instructions and, oddly enough, Casio and it's distributors never released a full description of the whole CPU's instructions set, although Casio published an incomplete "Technical Reference Manual". The processor was an Hitachi HDS61700. It contained a small amount of ROM and RAM, as well memory management and I/O circuitry. The memory was managed like a virtual disk. Several Basic or Assembly programs as well as ASCII text could be stored together in the same RAM area. Two extensions were released for the PB-1000, the FA-7 Serial, Parallel and tape recorder interface, and the rare MD-100 3.5" floppy drive unit. The PB-1000 was followed by the **PB-2000** which lost the lift up display but had the unique feature of being programmable in ANSI C language.
