Are eisa computers really less easy to be found, now ? If so I suppose that I did a good thing by caring for the Ast Premmia 4/66d that I bought so many years ago. Is Buslogic among those scsi controllers ? :) Alessandro -----Messaggio originale----- Da: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] Per conto di Liam Proven Inviato: marted? 16 aprile 2013 14:40 A: General Discussion: On-Topic and Off-Topic Posts Oggetto: Re: Mylex MAE486-33 BIOS needed On 15 April 2013 20:17, TeoZ <teoz at neo.rr.com> wrote: importantly is the BIOS. did find the EISA config files. well (have one of them at least).

EISA died out kind of quickly when PCI came out which was well before the P3 era.

He stumbled upon *pallets* of cases of shrink-wrapped 8" floppies for cheap. He picked 2-3 pallets up with the intent of trying to sell them as novelty items including analog clock faces. After several years of essentially zero sales in the early 1990s, he got tired of them taking up floor space and chucked the lot. He saw the future value of them, but couldn't afford to wait around 10+ years for demand to rise. With the fluctuations of of the fortunes of the PC biz, his company didn't survive to the 21st century, so they'd be gone now one way or another, but I do look back at that mountain of media and wish I'd had a climate-controlled place to store them. -ethan

Asses or assets? The problem with the floppies I think is even "nos" or cib or used the oxide can still flake off in your drive so its sorta a risk either way. -----Original Message----- From: Dave Woyciesjes <woyciesjes at sbcglobal.net> Sender: cctalk-bounces at classiccmp.orgDate: Thu, 18 Apr 2013 14:56:37 To: General Discussion On-Topic and Off-Topic Posts<cctalk at classiccmp.org> Reply-To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: floppies On 04/18/2013 12:50 PM, Ethan Dicks wrote: Hind-sight is 20/20, they say.....

humph,, And I'm sitting on two 20 gallon crates of 8" with CP/M software and data on them and maybe a few new boxes along with a large box of RX01/2 media mostly RT-11. Haven't check them in about 10 years but I bet from the sample of RX02 and the few I use for the NS* 8" floppy system I'd expect they are still good. Same for all the 5" flavors, though generally I found the 1.2MB 5.25 to universally to be with worst for bit rot. For standard 8 and 5.25 stuff I have had few failures. For 3.5 I've had much grief with cheap media shedding to the heads (sometimes the drives fault) and then taking the next disk with it by abrasion. Thankfully I still have 10 boxes of sony (from the late 90s) 720K and a few boxes of TDK and other names from the same period 1.44mb stuff. I use those in my frankenstein Kaypro 4/84 and the AmpoLB+ mostly and also the Epson portable disk (3.5" equipped systems I run often). Once I realized some media was crap, and some drives as well I cleaned house years ago of the junk to trash. Allison On 04/18/2013 12:50 PM, Ethan Dicks wrote:

They are older PC drives from the time when 3.5" floppies had a drive select switch or jumper like the 5.25 units did. Very reliable too. That system has a 45mb Fujitsu scsi disk. The kaypro4/84 uses them as well with the Advent TurboRom and Disk Personality board The front panel has a 5.25 and there are three 3.5", two in the remaining panel hole and another inside with the boot disk. They run in 782K format as the machine can't do disk IO at 1.44 speeds. With the 4 drives there are about 3mb of storage total. I also have a SB180 (micromint) in an old PS2 case and uses the PS2 drives directly and they also do 782K format. I used that case as I needed the power for a 20mb disk and Adaptec SCSI to MFM controller. I never adopted 1.44media with exception of PCs as it was default for them. For those I use toshiba, teac, newtronix, and a few others (I have a box of PC floppy drives). They are very infrequently used and likely no new machines I build will include them. Even though most ITX board do have a floppy interface. Primary portable storage on PCs are CD, SD, CF, and USB as they hold enough for what I do. For older machines floppies are used where controllers exist. though I work to fit more modern media where possible. Allison

Things that are absolute never are. there where at least three typce of IBM, some only 720, some only 1.44 (though the could be convinced...) and the dual version. Having had PS2 as in the early base 8088 version and the non ISA bus versions. Much weirdness. ;) Fred you and I know using standard and floppies in the same sentence is asking for pain. PC (help me here) standards were best at making it worse. Allison

You might need to strap the RWC signal (Many of the IBM PS/2 1.4M drives did not have a media sensor and relied on RWC signal from the FDC)

The board was missing 4 chips, 2 are Dallas RTC chips (DS12887, DS1225) which are easy enough to get, a 27512 (thats the BIOS), and a 8742 (keyboard controller correct). Are all the keyboard controller chips of that era pretty much the same and interchangable?
