Anyone have any idea what this thing is? Find the power supply for it, hook it to a TV and boot it up. Sounds like a whole computer!

What is this machine? (Pertec)

by scott＠saskatoon.com

I'm curious if anyone knows what this machine is. (What OS it runs, etc.) It's a Pertec machine with a 68020, Floppy, SCSI?, looks like 4MB RAM, and serial(?) ports on the back. The power supply has a "ST-100" stamped on it (along with a June 1988 date) The backplane itself has ST-98 Rev 003 written on it. The main sockets on the backplane are two 60-pin slots. It claims to be a "3226", according to the plate on the back. That info also says it's of type "P7005". I haven't seen the machine... this is info I've collected from emailling the owner. (I guess this machine is a year too new for this list. I hope you'll forgive me.) thanks ttfn srw

More Altair Scans

by rcini＠msn.com

Hello, all: Just an update on the Altair info that my friend is scanning for me. Below is the list. He is preparing a ZIP disk for me containing the files in the PDF forman. I'll have it in a couple of weeks. He also said that he wants to scan other materials that he has, such as Altair Basic and Extended Basic manuals, the Assembler manual and others, plus the MITS "Computer Notes" as well as material from other manufacturers. I told him that I want it all (like I would really say no?)

Right idea, wrong item...

by B.Lane＠PSS.Boeing.com

I hate it when this happens... As it turns out, it's not an RRD40 CD-ROM drive I should be after. According to a manual I just picked up, it's the RRD50. With that in mind... Allison? Tim? Would either of you happen to have a line on a DEC RRD50 drive and controller? And no, Allison, I've not given up on MOPbooting. It would just be a Nice Thing if I didn't have to depend on that every time I needed to do a load. Thanks in advance. ==Bruce 'Why me?' Lane (kyrrin(a)wizards.net)

Epson PX-8, no power up

There was Marvin, the socket labelled ROM1 should have an Epson ROM in it, and as far as I know it is the O/S ROM. ROM2 socket on mine has Portable WordStar and is not necessary to run the system as far as I know. In fact, I just pulled the ROM on mine and the system still came up (BTW, those ROMs are neat...they have a little plastic bucket that the ROM sits in that makes it easy to pull them out and re-insert them). My battery is worn and does not hold a charge anymore, but it will recharge and operate for a little while (how long I don't know since I never have it on for more than a few minutes) but as soon as I plug in the power supply it works fine. Inside the ROM compartment you will notice an "Initial Reset" button. Have you tried pressing that? There is also a dip switch inside (SW4)...my settings are as follows: 1:ON 2:ON 3:ON 4:ON 5:OFF 6:ON 7:OFF 8:OFF There is a smaller compartment on the bottom near that back of the unit...did you make sure there is a ROM in there? Is it seated correctly? Hope this helps in some small way.

Zenith ?????

by groberts＠mitre.org

i believe it's a "dumb terminal" that uses NTSC video - probably emulates either the H19 or VT100 (or both). i think the "save" button is used in configuring (and saving) terminal options. - glenn At 04:00 PM 12/31/70 +0000, Marvin wrote: >Among the things I picked up yesterday was a Zenith Data Systems >keyboard, model ZTX-1-A.
