Powys County Council’s first PC

We were passing through Llandrindod Wells earlier so took a welcome coffee break and whilst on a wander, we popped into the local museum where I spotted this awesome HP machine.....

£18k was a bit more than my paper round would stretch to BITD.

Very interesting machine - CPU is derived from their minicomputer, is a 16-bit CPU implemented in a four-chip set. And there are two CPUs.

Thanks Ed, I hadn’t had chance to Google yet so that’s great ta. I actually recognised it from my early days in the radar business in that within the GEC-Marconi group we had lots of high-end test equipment such as ultra-sensitive noise measuring sets and network (the RF kind) analysers that began to use these or similar derivatives as controllers.

I wonder how tricky it would be for Richard Russell to code a version of BBC BASIC for it!

I used these at work back in the 90's, they ran HP BASIC. We had a pile of them that were kept for spare parts, including huge 8" twin floppy drives. Everything weighed a ton, though the monitor was detachable for transport. The tape drives and printer were modular and could be easily swapped with donor machines.

There is more about the 6845 at http://www.hp9845.net/9845/

Interestingly, this machine had an I/O processor, language processor architecture much like Acorn's tube concept.
