That was actually the specification for a card which I was designing called GoldFire which was never finished for a variety of reasons I won't go into here.
It also had a an option for an ethernet and audio controller chip, all derived from PC tech of the day.
The reason for the name was that the design was started with the MCF5102 Coldfire chip that just came out. Unfortunately that proved to be a disappointment since it was really intended to be a 'bridge' chip between 68k and the (then new) Coldfire family of chips which then turned out to have a severely reduced instruction set and no way to make them compatible with 68k. This has remained so even today, with a caveat (see below).
Since it was intended to be a successor to the (super) Gold card, and it was using a Coldfire CPU, the name GoldFire was coined.
As it turned out, the MCF5102, the only fully compatible ColdFire was really a re-spun 68040, low power and with a maximum speed of 40MHz (and that was quite expensive), also in a low pin count case with multiplexed address/data bus. It soon became obvious that it was possible to buy second hand 68EC060 running at 66MHz which would be at least twice as fast, for less, hence the spec was changed to 68060, in fact, two could be used.
Unfortunately, what happened next was a rather large implosion of the CPLD market at the time. The age of free development tools was not there yet, and the CPLD model selected for the project seemed a good pick because there already was an (expensively bought!) development tool chain, and a second source supplier - the orignal was AMD and the second source Cypress. Unfortunately, AMD decided to sell their memory and PLD divisions, as they were concentrating on the PC CPU market. The PLD division got sold to their principal competitor, Lattice - and the very CPLD family selected for GF was immediately dropped from production. This also prompted Cypress to first raise prices sky high and simultaneously declare a lifetime buy on their second source, as they stopped production and were only selling existing stock. The last nail in that coffin was Lattice also changing their tool chain and stopping any support of that particular CPLD, and Cypress dropping any support at all, so new costs arose. Neither of the other manufacturers offered anything comparable at the time. I also then moved back from the US to Croatia and that was more or less the end of the whole project
It's kind of ironic that in the meantime I have been trying to save scraps of it as a LOT of work was already done.
Regarding Coldfire, the ability to at least emulate 68k instructions dropped in generation 2, was only added back in some chips of generation 3 and generation 4. The latter are still made but losing the battle with ARM based designs. A company called Micro APL (which I believe actually did some software for the QL back in the day!) did offer an emulation package that emulates the required 68k instructions in software, but that required a rather expensive license. As luck would have it, MicroAPL has made the emultaion pack available for free recently, so there might be a way to design something QL compatible based on a V3 or V4 Coldfire chip.
