I have a slight problem which I hope someone can help me with. The computer science club here at Waterloo has a couple of HP9000 series computers with what we think are 68000 processors. The only trouble is, when we open them up, the only thing that can be found that even vaugely resembles a microprocessor is a 10x10 PGA (number of centre pins removed: unknown) labeled as follows: (Motorola logo) 1820-3288 GN78427 According to all the data books I have looked in, this is either a 68000, 68010, or 68012. What we think we have is a 68000. We want either a 68010 or 68012. I suppose that a quick software check should be able to tell the difference appart between the 10 an 00, but not the 10 and 12. Besides... we'd like to know exactly what we have. Can anyone help? Thanks. -Andrew. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Andrew D.

We want either 1820-3288 is HP's internal part number for a 12 MHz NMOS PGA 68000 When you boot up the system the ROM should also put on the display what processor, FPU, amount of memory, etc that you have.

A 68012 comes in an 84 pin PGA (more pins for the added address lines and the RMC line). Also, I believe the GN7 mask code is for a 68000. ---- Eric Smith esmith@apple.com Opinions expressed herein are not necessarily those of my employer, family, friends, computer, or even me! :-)
