Hello, I am posting this for a friend at CSUS in California. I have someone who is trying to work a HP-125 and he needs some specs on the computer and if there is possibility some help on figuring out how to get the disk drive unit working ( needs a special? cable). This HP-125 system is composed up of a huge monitor and moveable keyboard, with a seperatbox unit holding the CPU? and disk drives. It has a port for the floppy control and a GPIB port. It was made sometime in the early 1970's. Any information about the above system would be greatly appreciated. Please send all pointers and letters to lewj@athena.ecs.csus.edu. Thanks. another wise man say: Ancient Machines which die suddenly also take their operators with them.

Check with your local Office of Education. Many school districts used HP125 for a number of years and chances are they still have info on them - maybe even some hardware you could get. If this doesn't pan out send me message at stanb@hpnmdla.hp.com and I will get you in touch with some locals who still use 125's!

Its operating system is CP/M. The CPU (an Intel 8086 I beleive) is contained on the motherboard in the large monitor. The HP 125 has four rear-panel ports. Port 1 is a serial printer port that requires a special cable from HP. Port 2 is a standard RS232 serial port. The other two ports are HP-IB (GPIB) for connecting the disc drive (a dual 5.25" floppy) and the connector for the keyboard. The HP 125 has 128k of RAM, 64k for the user application. The word processor used was HPWord125, a variation of "Spellbinder" by Lexisoft, Inc. At the time it was a pretty good word proccessor, but its 27k text limit soon forced it out of use.

re: Spellbinder... There was a version of Wordstar that ran very well on the 125. It even used the keyboard function keys. Memory etc: 64K for the CPM processor, Only 16K for the terminal. The machine was essentially, a 64K CPM computer and an HP 2621 terminal on the same board. It used 2 Z80 processors, one for the computer and one for the terminal. Disk (+ printer and plotter) access was via the HPIB (GPIB) port. The machine also had two serial ports which could be used for communication or a printer. The whole computer is in the "terminal" case. The external box is the disc drive. 8, 5.25 and 3.5 floppy discs were available. 5-15MB hard discs were also available. The machine was released to the market in 1981, one week before IBM released the original PC. For a CPM machine it was quite good but ... Kevin Wentzel

The HP-125 was a CP/M machine, more or less. Don't recall if it was 8086 or what chip, but the cable you want is an HP-IB cable (there is an IEEE equiv).
