Re: pdp-8/e restoration.

Note: TU58 (variant of DC100 tape) to my knowledge was never used with PDP-8 in any flavor. There is no reason why not other than no driver and it 8bit only and the blocking is 512bytes. The 8bit part is solved by storing 2 words (12bit word) to 3 bytes (24bits). It could be quite handy as a

Booting OS/8

OK RX8 is in the pdp-8/e connected to the RX01. OS/8 floppy in drive. All I need is the toggle in bootstrap and you never know. Rod -- Wanted one pdp-8/i rocker switch leaver to copy.

Re: Avoiding Shorts While Testing a DIN Plug

I'm with Fred on this one. Get a socket, solder some pigtails to it and use that, if you're worried. I'd definitely do that if the plug were a mini-DIN. Standard DIN, not so much. Just use a smaller probe with only the tip exposed through a bit of "spaghetti". --Chuck

ftp.compaq.com mirror

Hi folks, Managed to rescue a Compaq Deskpro EN from the scrap pile at work today and realised it has a proper floppy controller so I can install a 5.25” drive. Trouble is ftp.compaq.com has disappeared so getting drivers for win98 is going to be difficult unless I have

Not Booting OS/8

Hi List Well not surprisingly it didn't. I keyed in the bootstrap and checked it a couple of times. Pressing clear produced a healthy clonk from the RX01 (RX01's and 2's clonk a lot). Pressing clear started the program but no activity from the drive. So next move will be to try and

Re: ftp.compaq.com mirror

I have the whole archive, but you'd have to tell me which files you need. Note that most files from ftp.compaq.com are still available on ftp://ftp.hp.com/ (including all softpaqs). You should be able to install Windows 98 without any special drivers, and then use Google to find the specific drive

Re: Disk imaging with IMD - question

Quick question, Rich--what kind of media are you using to test by formatting to 1.2MB? If they're SS media (as indicated by the position of the index aperture), your drive will probably barf if you try to access the disk as double-sided. We've all been spoiled by 5.25" and 3.5" media which doesn
