I have come upon a junked UNIX PC (particulars below). The machine was trashed because of presumed disk failure (grounding strap noise from the HD?) I would appreciate any advice on restoring it or using the parts to build something else (know of any good 68020/bitmap/HD boards?). What I would like is a multitasking PC which runs GNU Emacs and uucp. Thanks!

Since you are talking about the PC7300, I presume you have the case that only can hold the half-height drives. In that case you would be constrained to something of that size. I've seen hard drives up to 76MB in 1/2 height using the MFM recording format. Seagate ST251 (40Mb) drive would be an acceptable replacement. Anything less than 40Mb is tight for a development environment. Any 5.25" 360K floppy drive would be acceptable, assuming the strap settings were set correctly. The drive inside the UNIX PC I believe is made by Teac. There has been some success with using a 3.5" 800K floppy on the UNIX PC which will give you extra floppy space. (Speak to Darren [darren@bacchus] for further details on this subject) |> Cables for disks.

The PC7300 came with less on board memory, and I believe couldn't be expanded as high as 4MB (unlike the 3B1). |>Q: What does it mean when people say they are running OS version 3.51 |> is this S5R1? R2? R3? |> The 3.51 release is the release number for the AT&T UNIX PC operating system. It has *nothing* to do with System V release 3.XXX. The UNIX PC Operating system is somewhere around System V release 2 (SVR2), it has some Bezerkley enhancements (BSD), plus somethings that are not up to the SVR2 and are still lagging behind at SVR1. |>Q: Is purchasing the chips on qty 1 going to be prohibative? |> are any of them custom? |> Doubt it sincerely. It probably would be cheaper by an entire *new* machine. Most of the chips are custom, except of course for the 68010 CPU that you are missing. |>Q: Would the platform run 'X'? Or is the window system reasonable? It doesn't run X-windows, and I doubt it ever will. ;-) -Lenny -- Paper-net: Lenny Tropiano | @-net: lenny@icus.islp.ny.us ICUS Software Systems | !-net: ...sbcs \ PO Box 1 | boulder \ Islip Terrace, NY 11752 | talcott !icus!lenny Vocal-net: (516) 582-5525 [work] | pacbell / (516) 968-8576 [home] | hombre / Telex-net: 154232428 ICUS | Another-net: attmail!icus!lenny

Yes , it has the same cpu and runs the same software the main difference is that the 3b1 has more memory (usually 2m) and a larger disk drive.(usually 67m) > >Q: What does it mean when people say they are running OS version 3.51 > is this S5R1?

As far as some of your hardware questions go, I can't answer however the disk drive replacement question can be . There are several authorized drives for the 7300, one caution though is that the controller determines the density not the type of drive, on the 7300 this is located on the mother board I believe ? (not sure) my brother in KC has replaced his 20m with a 40 m. later.... James M Doherty - SWBT - Advanced Technology Planning 1010 Pine St. - Room M110 - St. Louis. MO. 63101.
