Unlikely, but ... finally this ends my waiting in front of my computer for a reply - I grew really hungry over time. Unfortunately I do not have this card anymore - I gave it away, as I was not able to find drivers for it. Martin

Recently, I learned that there were a few issuses of a Japanese Magazine "Oh!HC" which was obviously promoted by Epson. Unfortunately I was not able to find any scans of these issues. Do we have some Japanese readers in this Forum who could provide links or scans of these issues? Even if we...

Thanks again - this Russian web site is interesting - too bad it is not available as a single document for download. They mention muLISP-81, -85 and -87. Embedded in the text, I also found archives of subsets of the muLISP-85 and muLISP-87 installation for download (on this page...

Thank you for the helpful links. I would also be interested in later muLISP versions (muLISP-82 ... muLISP-87) because Soft Warehouse changed many of the built-in keywords/functions and extended the number of functions considerably. They seem to have moved closer to "standard" LISP...

Resurrecting this old thread... as it has become easier to scan documentation. Documentation for the early versions of muLISP and muMATH as well as for Derive for CP/M as well as for MS-DOS still seems to be missing from the usual archive sites (like bitsavers, archive,org). Maybe someone...

... and it is a MS-DOS function, not a BIOS function ;-) Your code will also run on non IBM-PC compatibles with the proper MS-DOS version.

Several software products had been available for the HP 110 and the HP Portable Plus. Some of them came on floppy disks and some in (EP)ROMs. A few are available for example on hpmuseum.net or on www.jeffcalc.hp41.eu. However, there are still many programs missing. While many generic MS-DOS...

You might also try to use the MS-DOS command SHARE after making the USB printer into a network printer. See https://superuser.com/questions/182655/how-do-i-simulate-a-parallel-lpt-printer-with-a-usb-printer

According to the internet HP has about 1000 employees in France and 550 of them in Grenoble (97% of them engineers or managers). The rest is located in Paris/Meudon. What they actually do today ... I don't know.

Since 1970 HP had a larger production and development facility in Grenoble... They made Vectras and terminals and more. https://www.hewlettpackardhistory.com/item/the-french-connection/ https://www.hpmuseum.net/divisions.php?did=25

On the HP-150 "no display" and "no beep" often means a broken video board which is tedious to diagnose and fix. Additionally, there are two standard battery cells on the video board which leak when not removed and they may destroy more. The keyboard (46010) is not so easy to find - it is no...

During the last days I tried to run Wordstar on my HP 150. A disk image of Wordstar 3.3B, adapted for the HP 150 is available on the HP Museum web site. They also show a screenshot of the installer, which looks as it should. Unfortuantely they don't show a screenshot of the main program. The...

Thank you for looking - this is still a mystery. It is hard to believe, that HP would roll their own Pascal development system for the MS-DOS systems and not offer it for sale. Or at least write something about it in their Journal. I am well aware of HP Pascal for HP 9000 systems. Pascal...

I am trying to identify a Version of Pascal for MS-DOS. It seems to be a variant of UCSD Pascal, but I am not sure. Maybe the following details ring a bell somewhere... HP obviously used this system to develop software for the HP 150 as well as for the HP Vectra - MS-DOS 2.x and 3.x systems...
