Hi all,
Recently an HP1000F with missing parts but a nice front panel went up for sale on eBay, not wanting to miss a machine that I had been after for some time, I took the opportunity and bought it, for probably too much money.
It’s in very nice shape overall, and looks like it came from a lab environment, however the power supply and memory subsystem was removed and the rest of the machine was sold on at some point.
I haven’t done a ton of work yet with it, but I did discover an FPS AP-120B interface on eBay, so I would like to restore the machine to the point where it may be useful as a host machine.
I either need to build a new power supply or replace it with an old one. I have been looking into a meanwell replacement but I’m unsure about supply sequence requirements and the power supply manual from HP only serves to confuse me more. Perhaps a very detailed reading is required. This so far has been the major issue with restoration.
I did write an assembler for the machine, in Python, which worked well enough to match machine code I found on the internet, but I would like to port this to something more sensible such as rust or go, now that the program flow to generate code has been figured out.
The architecture here is very cool, it, like the DG Eclipses of the same era, has its roots in 1960s designs. It has a very simple RISCesque architecture. Of course by the time the 1000 was announced, the architecture had been extended substantially and it was quite capable for the time and purpose.
If anyone has a spare power supply, I’d be happy to chat about taking it off your hands for a fair price. As for memory, I'm fairly certain I have a good plan to get more, and most of the requisite parts.
