the tablet interface box, yes that brings up another enigma... as mine doesn't have one! Keyboard and rat plug into the tablet which then plugs directly into the PB, it does have a rotary encoder but it doesn't seem to do anything, i think the entire system is an old one so maybe predates the interface box? i have noticed that during boot it does say 'A4 tablet expected' even without the tablet plugged in, was there a switch, jumper or software option that could affect it? |

Re: 1980s Quantel Paintboxes
Yes, the control box solution came in late 1994 / early 1995, with Wacom tablets. Your control system must be prior to that.
The rotary on the back only selects NTSC or PAL, locations 0 and 1 are the only active locations AFAIK (see attached, from HAL manual, but tablet arrangements were the same). I don't think there are any setting links on the CPU for tablet size, there are a row of DIP switches that pertain to tablet use, but I'm pretty sure they only select the serial I/F type (RS232 / RS422). It is possible there are setting links on the tablet interface board, but in all honesty I don't know for sure. I never saw a Paintbox shipped with an A4 tablet size, but Picbox tablets (when fitted) were invariably A4. The later tablet / interface box combination should work with earlier machines, may be worth a go if you have the parts.

Re: 1980s Quantel Paintboxes
Are the interface boxes you have for a paintbox? If it's the boxes I'm thinking of (off white, about the size of two small house bricks 'side by side') then these were used across various bits of kit - Paintbox, Hal, Encore etc and each one will obviously have custom software in it. Just a thought.

Re: 1980s Quantel Paintboxes
Yea that sounds like them, with 'RJ' style input sockets for the keyboard, joystick and tablet, i have two of them along with a A4 tablet, A3 tablet and one keyboard
TBH i was under the impression the tablet, rat, joystick, keyboard protocol was standard across all the systems. But was switchable between RS232 and RS422. But i am of course no expert! |

The firmware in the Quantel tablet I/F also varied for different Wacom tablet types. There is one version of the Tablet Interface box that is compatible with a range of tablets, selection by rotary switches. This version usually had a table of supported versions Vs switch settings stuck to the box. I loose track of how many generations of Wacom tablet V-series went through, but it sounds as though you have been unlucky with your pen / tablet combination. As I inferred above, it may be possible to buy a replacement Wacom pen for the relevant tablet, although they, annoyingly, seems to regularly make these obsolete

Re: 1980s Quantel Paintboxes
thanks Chris,
i have used several generations of wacoms on the PC (both serial and USB) so i know their game, that only the same generation pens work with the same generation tablet. It's most annoying especially as there are always a good supply of tablets on ebay but they are always missing the pen!! - maybe the pens run off with the Biros to form a uniquely biroid lifestyle? I'll stick with what i have at the moment as it works, maybe something will come to light about why i can't use the full area of my current tablet |
