Saving the Quantel legacy one luma sample at a time, blundering with electronics, computers & other weird things, sometimes fixing stuff.

Spent most of today testing and cataloguing these CPU cards. These were used in the Quantel Paintbox, HAL, Editbox and Henry from the 1990s. They each have a 68040 @ 33mhz, 64mb RAM, DMA, Inmos Transputer link and much more. The open machine here is a Quantel Paintbox Express i was using as a test platform.

Who likes #Acorn #Archimedes stuff? I managed to obtain this huge folder of services manuals for several different models. In the back it even has schematics for the A3000 which unfolds to what must be at least A1 size.

New video! A decade before Adobe #Photoshop, one company made a bespoke computer whose artistic capabilities helped define the look of 80s and 90s TV shows, music videos, and print media. So why don't we call digital photo manipulation "being Paintboxed?"

Big thanks to DextersTechLab on YouTube (youtube.com/@DextersTechLab) and Adrian Wilson (quantelpaintbox.com) for their help on this video!

This is an excellent and fun feature on the Paintbox, what is did for 20 years in the broadcast industry. Giving artists the digital tools they needed in the 80s and 90s...

Just preparing a vintage Arraid SMD disk emulator to replace the even more vintage 14" hard disk for a friend's Quantel 'classic' Paintbox.

The 5D 'Masher', a dual Pentium 3 Windows NT PC dating from 1999 that renders video effects for Quantel machines. It's an absolute tank of a unit. Hardware made by Intergraph!

This lovely looking PCI card is an Intergraph SMT491 Raven DS. Part of the Intergraph StudioZ and provides SDI video, uncompressed digital video at 270mbps. From around 1998/1999. Also used in the 5D Masher, a PC add-on for machines to render video clips with effects.

Here we have a Size Control card from the DPB-7001 Paintbox with a PAL16R4 removed and in a DuPAL reversing tool ready for analysis!

@philpem that is weird. Response time maybe?

First try at dumping the RAM in the CFT-2100 #analogcable box failed... looks like the extender cable and sniffer board loaded down the CPU bus too much and made it bug out.
Trying again with the logic analyser method... #hacktv

A General Instrument CFT-2100 set-top box, disassembled, with a logic analyser connected to the ROM socket.

This new 1984 demonstration of the DPB-7001 Digital Paint Box has just been found. Filmed in Monte Carlo, nice!

@philpem yes, there's real beers on tap, Belgian beers in bottles and a fire downstairs with blues and northern soul sounds playing, perfect!

Currently taking a break from fixing old and broken Quantel machines with a break in Windermere's most quirky pub.

Good morning and a Merry Christmas. Today a picture of a rescued 40 year old EPROM programming device #Diagnostic82. A master with up to four copies, small monitor to list or change content. A #ZilogZ80 CPU works internally, so it aroused my interest. I rescued it from the electronic waste, repaired it and lovingly restored it to its original condition. Incidentally, the type designation "Diagnostic" is particularly "helpful" to find something about it on the Internet.
