Hello, I need some help about the board Model 5400, ASSY00060-13 REV T urgently. Can you send me some technical documents(if you have any) about this board. Do you have any information about that if I can get an extra board from the producer or not ?

Need ROM for AP-64e Apple ][ EPROM writer card

by sellam＠vintagetech.com

Does anyone else have an AP-64e EPROM writer card for the Apple ][? If so, is there any way I can get you to dump the ROM and send me the file? I have two of these: one is missing the ROM and the other has the ROM (a 2716 EPROM) but it has been erased apparently. Also, can you write a tutorial on how to use it? The manual is available online as a PDF: http://www.apple-iigs.info/doc/fichiers/ap64eprom.pdf ...but the Engrish in which it is written is so mangled it's hard to make out what it's saying. Plus, it excludes certain key documentation, such as which side is "on" for the programming switch, and the DIP switch setting chart doesn't define what 'x' and 'o' mean in the context of the switch settings.

British Computers.

The microfile 1000's I used were about the size and shape of an original IBM XT, but with multple serial ports on the back rather than pc style screen/keyboar: You connected up dumb terminals to use. We ran BOS on them, but think they were intended for ConcurrentDOS. Rob

Docs on panel meters?

by ethan.dicks＠gmail.com

>From time to time, I run across panel meters, at hamfests, in the dustbin, whereever. I'm sure, in most cases, they still work, but without pinouts, it's a bit tough to put them back into service. The latest one I have is marked with the following... Fairchild Panel Meter Model Number 300555 5VDC Powered: 2V F.S. Range 7825 (in paint, presumably a date code) It has an 11-pin connector on the back, and inside, under the red plastic cover, is 4 7-segment LEDs, som resistors and caps, plus 4 black, unmarked epoxy blocks I can't identify. There are a number of traces going under each one, so I'm presuming they are bare dice that were glued to the board, then encapsulated, but unlike modern examples of that practice, these are in square-sided epoxy blocks. I don't need to know the entire circuit. Mostly, I just need to know where to attach Vcc, GND, and the sensed voltage. Obviously, googling for "fairchild 300555" turns up nothing. Not at all unusual for something of this vintage. Thanks for any pointers. -ethan

DEC Rainbow Hard drive.

If you got > the later firmware and put it into a -A mainboard would the machine (a) > still work and (b) let you boot from a hard drive (asuming you'd also >fitted the controller card)? I would be surprised if that did work. There are some hardware differences in the 100A and 100B. The graphics hardware is slightly different, and the quantity of memory on the motherboard is different. I'm sure there are also more subtle differences which I didn't mention. Anyway, it proably wouldn't work, but then again, I've never tried. There are also other differnces that have nothing to do with the firmware. The 100A used an AC fan, while the 100B used a quieter DC fan. The 100A power supply was not quite beefy enough to run the big hard drives, although it would unreliably work. The power connector on the 100A for the second drive was also excessively short so it wouldn't reach the standard DEC hard drives alone anyway. Usually, 100As have the block letter logo on the front, while 100Bs have the script Rainbow logo. -Jeff jba at sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org

Any Microchannel collectors around here?

by lproven＠gmail.com

I ask 'cos amongst much other junk, I have a largish box full of MCA cards that I'd like to get rid of. If this isn't the place, I welcome recommendations of elsewhere to ask! Most are some kind of audio/video thing - lots of BNC connectors. A couple of elderly NICs and things, too, I think some 8514/a adaptors, maybe some SCSI cards... -- Liam Proven ?

VAXstation 3100 FB problem

by Peter.Coghlan＠EUROKOM.IE

Hi Tore, I am only catching up on my email now after a weeks absence. > >Hello, I've got a VAXstation 3100 (Thanks, Peter Coghlan!) that I You're welcome. I Hope you didn't have any problems transporting the machine home.

However, the card can also be used in a Vaxstation 2000 and the firmware in a VS2000 appears to be very similar to that in a VS3100, so I had a look in my Vaxstation 2000 and Microvax 2000 Maintenance guide which does have some details. It suggestes that 0016 is the status from the test and says that this can be ignored! It goes on to say that 005 means "ID data bus" and 2 means an error (as opposed to "no error" or "informational"). Unfortunately, I don't know what "ID data bus" could mean. > >Does anyone know what could be ailing my new toy? The machine will run >perfectly using the mono adapter, though VMS 7.3 will crash hard when >trying to access the device (starting the X server). > When I tried it last, it produced an error during the power up self tests (probably the same error you are getting) but it was possible to ignore the error and boot VMS and use Decwindows without any apparant problems. Its possible that the version of VMS/Decwindows you are using is more sensitive that the one I had. I will see if I can find out what version it worked ok with. I suspect it was V6.something.

Personality modules for Heathkit 4801 EPROM Programmer?

by sellam＠vintagetech.com

I don't suppose anyone knows where one can get a set of personality modules for the Heathkit 4801 EPROM Programmer? A manual would be nice also ;) -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
