Thanks to Jim, a world was opened for me. Using the original BIOS of my IBM AT type1 motherboard that consists of 2 PROM each with 32KB I used BIOSUTIL to add the geometry of my hard disk to position 15 (the 1st free position) by recalculating the checksum with BIOSUTIL (this time understanding how it works) . The difference between the original BIOS and the BIOS modified compared with WinHex is as follows: Offsets: hexadec.    E4F1:       00        68        0368h=872cylinders  E4F2:       00        03  E4F3:       00        10        Head=16  E4F6:       00        FF  E4F7:       00        FF  E4FD:       00        68        0368h=872landing zone  E4FE:       00        03  E4FF:       00        24        36 sector/track  FFFF:       AD      A5   9 difference (s) found.   The table with the disk’s descriptions begins with disk 1 from E400 ending with the disc 47 to E6EF while from E4F1 to E4FF were inserted the values of the new Hard Disk. BIOSUTIL has taken steps to change just only the byte FFFF from AD (1010 0101) to A5 (1010 1101) so that the checksum of the file with the modified bios is identical  (?) to the contents of the original file of the PROM.     All to means: BIOSUTUL works fine with original IBM BIOS bun NOT with AMI BIOS.   The problem seems to be solved for the table discs, but as with the original BIOS to power had always the same datas: date, time, type drive A, 512KB DRAM, now all these values vary at each switch on (eg, the base memory is to 0KB instead 512KB).     How can I insert data into the BIOS for to have the correct ones stable for final configuration of the machine that I have?   Enrico -- Z-Light e Z-Pro: servizi zimbra per caselle con dominio email.it, per tutti i dettagli Clicca qui http://posta.email.it/caselle-di-posta-email-it/?utm_campaign=email_Zlight_… Sponsor: Idee regalo classiche o alternative?

More detail teletype parts and GE Terminet 1200

by billdeg＠buzz1.com

A few weeks ago I sent some photos of teletype parts units and a GE Terminet 1200 that I had available, so I could get an idea of interest/pricing. I have added paypal links to parts, with better pictures so people can order whatever they want. The pricing is based on offers I received privately. First come first served. I will mark items as SOLD but leave them online. http://vintagecomputer.net/itemsavailable/2014/ Directions on this site. Bill

curious to know if anyone knows what computer this is

The story indicates that they had four Univac V77 minicomputers there, in various configurations, as well as six VAXes. I imagine your photo relates to that. http://books.google.com/books?id=OrmcqtZUTMoC&pg=PA19&dq=%22mickey+mouse%22… You can also watch a video of the opening ceremony of Epcot Computer Central (10/18/82) here: https://www.youtube.com/watch?v=U3lZW39D1pQ - featuring what was known as "The Computer Song" There is a photo looking into the processing center at Epcot here: http://www.solarius.com/dvp/wdw/communicore.htm - I think you can see some Sperry terminals on the right.

Looking to get into a Mini Computer, PDP or something like that

by slandon110＠gmail.com

I just want something I can learn, I do love the blinkenlights and switches, something about actually flipping a switch instead of a keyboard I love. One of my dream machines is an Altair or an IMSAI 8080, but those are out of reach. I really dont know what I want to do on it yet, looks like there is so much to learn. My son is 9 and starting to learn unix and old nix. So something that could run an old version of unix would be really cool :). Something perhaps I could tie into our vintage telephone system as well. Im a total noob at mini's, but the thrill of the regular stuff has kind of waned, Ive put my amiga online, my c64, my IIGS, everythign I got goes online and games. and thats all I do with it. Most of it has sat in storage. Thanks for all the input guys

by djg＠pdp8online.com

I'm looking for a program that runs under DOS 3.1 and will tell me CHS for all unreadable hard disk sectors. Anybody know where one is I can download? I can't find search keywords that filters out the modern stuff. A read write test would also be useful.

Hello all, I remember quite well CP/M days. It is indeed good news to hear that Gary Kildall has been given the recognition due. His contribution to 8-bit/16-bit world of computing was seminal. Murray :)
