The killer is once you find the CPU card, you need a cage/chassis/whatever to put it in. If your in the US and your are not in a hurry they show up. Then you need what is called a P2 adapter then a interface/breakout module MVME712/M and the cable that goes between them. What I discovered is the going price for P2+712 for a fortune, more than what you can find a CPU for and almost none have the cable. The cable is not your basic 64 pin IDC 2 row type, at least for the 167/177. Hence why I said the heck with it and started a board layout and started to accumulate the parts on the surplus market, my hope is by summer I will have all the parts to build both if there is any demand. -pete On Tue, Feb 14, 2017 at 12:43 PM, David Brownlee <[email protected]> wrote: > On 13 February 2017 at 21:12, Pete Lancashire <[email protected]> wrote: >> Running on a Motorola MVME167 or 177 ? >> >> This summer I'm going to make a replacement adapter for the P2 cable >> adapter to 712M, >> and after that a newer 712. >> >> I've been a VXI user for quite some time, and got the bug to do a 68K >> and 88K VME setup for fun. >> >> Finding the 712 connector interface and the P2 card is quite hard to >> do if you dont want to pay prices that take all the fun out it. >> >> I've been helped with a couple guys that have home MVME setups, and an >> soliciting suggestions on improvements and modernizations >> >> For example >> >> Replace the network connector on the 712M with a onboard AUI and a RJ45 jack, >> >> Change the serial connectors to 9 Pin >> >> Optionally include a serial to USB module, and maybe even a wireless interface. >> >> On the P2 card, add a 68 Pin SCSI socket, with the high byte pulled >> high (same as a 50 to 68 pin adapter) >> >> Change the 50 Pin SCSI connector to a 68 Pin >> >> So .. anyone still playing with these boards and need a P2 ? and maybe >> a more up to date 712 ? > > Would love to be playing with am 167 or 177, but just lurking on the > list - the closest I can get is an Atari TT (with VME network card > :-p) > > David >
