I recently got a IBM model 70, running SCO-ODT.
(nice package, only badly documented)
The only thing is I got the machine second-hand, and so I haven't got any
documents.
So my questions are:
1- How much RAM can I put on-board.
2- What's the square connector with all these pins.
3- Can I add a second HardDisk or do I need a extra (SCSI) interface
4- Why is the printer port on lp1
5- What sort of HardDisk interface has the Model70
6- Is there a good book about the MCA-bus.
Ilja,

Depends. A model 70-A21, which is what I have, can hold 8MB on the motherboard, in 2MB SIMMS (i.e. 18 1 megabit SIMMs on two sides). This is the only memory it can take, and it has to be specially designed for the PS/2 70-A21. Most of the other 70's can only handle 6MB on the motherboard, but I don't know about any of their restrictions. >2- What's the square connector with all these pins. Beats me. I can't see the back of my computer now. I can tell you that there are a serial port, a parallel port, a keyboard port, and a mouse port on every PS/2. Maybe it's one of these? >3- Can I add a second HardDisk or do I need a extra (SCSI) interface You need an extra interface. There was a discussion on this earlier, and the consensus was to go SCSI. >4- Why is the printer port on lp1 Don't you mean LPT1? You can change this with the Reference Disk, which I think is totally cool. I'd like to see Gateway pull this trick. >5- What sort of HardDisk interface has the Model70 I believe it's ESDI. Norton 5.0 says my 120-MB harddrive is using ARLL encoding. >6- Is there a good book about the MCA-bus. IBM has made the specs public, so you might ask them.
