You configure a scsi2sd by connecting a USB cable to it and running the scsi2sd-util configuration utility. It is extremely flexible and you definitely can change the SCSI ID. In fact, it can emulate multiple drives on multiple SCSI IDs simultaneously if you like. Also, power is only needed if the SCSI card you are using doesn't provide TERMPWR on the SCSI bus. Some early cards didn't provide TERMPWR but very quickly cards started providing it because active terminators need a source of power.

[@denniseldridge2936]

Just a comment on the 386-in-a-can thing. I once had the job in the early 80's of testing some huge IBM boards which were testbeds for fiber optic systems. They gave us chips to place in sockets on the boards which came in exactly the same packaging, and I actually had flashbacks when I saw those on your own Model 70. However the chips we were dealing with were slightly more expensive - tens of thousands of dollars each if I recall, so rather nerve-wracking to handle lol.

4:30 IBM built licensed Intel 386DX CPUs with "aluminium hat". It wasn't an uncommon sight to us IBM technicians back in the day. However: everyone wondered *why* they did it. A far as I can tell it was originally intended for the "Tempest" line of "electromagnetic tight" computers and the metal shielding should keep activity inside the can - and disturbances out of it. There were a lot rumours going around about IBMs participation on "Star War" programs etc. but that's largely made up. More likely is, that IBM wanted to maintain a second source for the - at that time - sparse faster Intel 386 CPUs and therefore licensed the design of some types.

[@IBM_Museum]

The IBM "silver-cap" 386DX CPUs are rather common on the PS/2 Model 70 and 80 systems; There are several different clock-rating versions (maybe this system had the CPU switched; It's a 'Type 2' planar running the CPU at 20MHz as seen) that fall within an Intel sequence, although we don't know whether it is an Intel or IBM-produced die. IBM did make 486DX/DX2 CPUs for their systems that were from Intel designs later. I'm interested in testing the CPU Reset Signature for a few models that I didn't have decades back when I started compiling this information: FRU 23F7189 is CPUID 0304h (C Step), likely 16 or 20MHz FRU 51F1783 is likely a CPUID 0304h (C Step), 20MHz or Step D0, 16MHz FRU 51F1784 is likely a CPUID 0305h (Step D0), 20MHz FRU 51F0352 is an unknown stepping, 20MHz FRU 32G3366 is an unknown stepping, 25MHz FRU 51F1797 is CPUID 0305h (Step D0), 25MHz FRU 63F7615 is CPUID 0305h (Step D0), 25MHz I've listed the comparable Intel stepping here, although I have never encountered a comparable 0304h CPU Reset Signature value on an Intel 386DX. I'll send Roman the appropriate links to list here, since I can't; Search on the FRUs to find more information at CPU World, etc.

[@IBM_Museum]

Looking on the comp.sys.ibm.ps2.hardware newsgroup, I was starting to compile information on those CPUs almost 25 years ago...

[@IBM_Museum]

BTW, the 4th line begins with a '1' (for the packaging), but the next four digits are a standard YYWW chip datecode sequence - Most of these CPUs were made in 1990 and 1991.

[@KAPTKipper]

Personally I'm glad my dad passed on the PS/2 series machine and opted for a clone. MCA bus was dead end. I supported a number of PS/2 models when I worked for a school districts. They were built like tanks. But it was all the proprietary hardware, like the floppies, weren't even swap-able between PS/2 models.

[@IBM_Museum]

There are the 40-pin "edge-connect" and later 34-pin (with power) "pin-connect" diskette drive - and they do swap between models (the low-end 8086-based Model 25 and Model 30 can run 1.44Mb drives because of this). IBM wanted modular designs that were 'tool-less'. The DBA-ESDI drives (as shown in the video) are even more "proprietary" to IBM.

[@KAPTKipper]

@@IBM_Museum The issue I remember after 30 years, was mounting size. They had drives with different heights and they couldn't swap. Keep in mind, in a school system, your supply of parts was low and there always was a variety of systems of different ages.

[@classicnosh]

I had a PS/2 but can't remember the model off-hand, it was one of my favorite computers.

[@lemagreengreen]

Even as a nerd it sometimes feels that IBM went to extra special efforts to make the PS/2 weird in so many ways.

[@Choralone422]

After losing control of the PC market to the clone manufacturers in the mid 80s, IBM was desperate to wrestle back that control through proprietary tech like the MCA bus which could be patented. In theory that would guarantee future revenue streams through licensing that tech to others. That makes a lot of what IBM did with the PS/2 seem fascinatingly strange these days. However, the "Gang of Nine" PC makers as well as most of the rest of the PC clone makers thumbed their noses at the majority of what IBM did with the PS/2 line that made it unique in favor of open standards. Eventually, IBM went along with the rest of the market, especially after Intel released the Pentium CPUs and the PCI bus was quickly adopted for both later 486 and nearly all Pentium class PCs. IBM pretty much never tried to lead the PC market again after the PS/2 line. Eventually that all led up to IBM selling off the PC division to Lenovo in May 2005. I had a front row seat to that transition. I was working for a large independent laptop & desktop repair depot who did a lot of warranty work for IBM as well as the other big OEMs. I was at the IBM/Lenovo Think Open conference which was held at the Contemporary Resort in Disney World in Orlando, FL in May 2005. That was a wild time to say the least!

[@jeremiefaucher-goulet3365]

I remember an IBM retiree explaining the change in color button had to do with some sort of regulation regarding emergency stop buttons on one of the international markets. But I also remember he said it wasn't a requirement, just an over-abundance of trying to play nice with the authorities. I wish I remenbered where I got this information, so please take this with a grain of salt.

When you remove a BIOS chip, it might be worth making a dump of it in case bitrot happens. My P3 board reported a 'cpu error' beep code when I first got it, even though it otherwise booted fine and I was able to reflash it from DOS which fixed the issue.

Those white switches were a requirement from the European Union, they weren't a commercial decision from IBM. IIRC the white switch was required for the CE marking because a red switch would symbolize it as an emergency shutdown switch which it is not.

I often do recapping of those old drives. I was wondering, have you ever considered using polymer aluminum solid capacitors as replacement capacitors? As these are the same size but do not have liquid in them and therefore do not leak. They are bit more expensive though.

[@Epictronics1]

It would probably work, but pollys also have different characteristics so no guarantee

After a bit of research its apparently preferable to use these in Audio equipment and monitors instead of the normal electrolytic capactitors. I will try to use them from now on for recapping drives and such. Hopefully they cause no complications afterwards.

Except they had only Intel DX silicon dies with no substrate, and they "glued" them to their own MST ceramic made interposers (and then sealed the substrate to the can with epoxy). There are some pictures of similar high density chips manufactured this way. If you unseal the can you will destroy the chip.

Pretty sure that CPU is the 386SLC an Intel-licensed version of the 386SX that had 8KB cache that got it as fast as a 386DX. It was IBM that packaged it that way, And they were used in the PS/2 line. Its basically a 386SLC on an OPGA-132 (O = Organic, much like how Barton Athlons were done years later) with a heat spreader and sealed in resin.

[@Epictronics1]

Could be, but my other SLCs are recognized as such in speedsys. This CPU is identified as a 386DX @21MHz

[@IBM_Museum]

They're ultimately Intel-designed 386DX, even if IBM fabbed them. The IBM 386SLC, 486SLC2, and 486SLC3 are 16-bit data bus and 24-bit address bus; These are fully 32-bit CPUs. Years ago, I tested them for the 'CPU Reset Signature', which Intel started implementing on the 386-class CPUs. The "silver-cap" CPUs give Intel responses. I can't provide links for someone else's channel, but here are the FRUs of several different versions, with these implementations actually being common for the PS/2 Model 70 and 80: FRU 23F7189 is CPUID 0304h (C Step), likely 16 or 20MHz FRU 51F1783 is likely a CPUID 0304h (C Step), 20MHz or Step D0, 16MHz FRU 51F1784 is likely a CPUID 0305h (Step D0), 20MHz FRU 51F0352 is an unknown stepping, 20MHz FRU 32G3366 is an unknown stepping, 25MHz FRU 51F1797 is CPUID 0305h (Step D0), 25MHz FRU 63F7615 is CPUID 0305h (Step D0), 25MHz As you said, the IBM 'SLC' CPUs are derived from the Intel 386SX codemask - the licensing agreement was that IBM could only use any derivative CPUs in IBM systems, not to package them for use and sell them where they could be on other brands. They also give a different sequence for the CPU Reset Signature (what became the 'CPUID' of the 486-class CPUs). Roman can provide a link to my 'INT 15h, C9h' ROM BIOS call page.

[@IBM_Museum]

IBM fabbed these directly from Intel 386DX codemasks just to help with production for their own systems the markings on the top denote the IBM plants ('9314' was the codes for Bromont and Burlington concatenated together), and the fourth line starts with a '1' for the packaging, then a standard YYWW datecode - These CPUs were fabbed in 1990 and 1991.

Those can type 386 chips weren't uncommon for a period of time in IBM PS/2, I *think* they're just Intel silicon in an IBM package but I have a nagging feeling they may be IBM's 386DLC silicon, either way it's brought back memories of the time when I worked as a bench tech repairing this stuff.

[@Epictronics1]

I thought we would find some sort of DLC too, but speedsys reports a regular Intel chip

[@IBM_Museum]

@@Epictronics1: Correct, there's no on-chip cache (the 'C' of the IBM part identification) or clock-multiplying - It's just an Intel core inn IBM packaging to help with production. CPU test programs don't check the CPU Reset Signature, for one, I've only seen IBM BIOSes provide that information at the 386 level anyway; It's easy to use DOS DEBUG or ROM-BASIC to retrieve that data. When the CPU is powered on or reset, it has the CPU Reset Signature in the DX register - that value must be saved away by the BIOS before it is overwritten as the system POSTs. Intel first implemented the CPU Reset Signature with the 386-class CPUs (and I've only seen IBM BIOSes save the value away for the 386 level, Phoenix BIOSes did it at the 486 level), and it became the "CPUID" instruction later, available at any time as the CPU operated.

[@Chernobyl250]

Do NOT try to open that can. It is not just a metal hat on top of a garden variety Intel CPU! Rather, IBM licensed the early x86 CPU models (all the way up to Pentium) from Intel and also built their own. IBM had a huge chip manufacturing capability since they custom made all of the silicon that went inside their own mainframes (S/360, S/370 and 30x0 models) and minis (AS/400s, etc.). So manufacturing their own 386s was nothing them. What you're looking at is a proprietary construction technique - you'll find hundred/thousands of these "Monolithic System Technology (MST)" chips in their own machines. I have dozens of boards from legacy hardware that are littered with these - all custom, and essentially zero information available on them.

[@IBM_Museum]

Ken Shirriff has opened the Token-Ring controllers that are in the same packaging. Under my tests (the CPU Reset Signature), these appear to be Intel dies (as you have said). IBM did their own dies (from Intel designs; the layout is identical) for the 486DX/DX2 CPUs.

[@hyoenmadan]

Yeah. These characteristic IBM metal can chips are MST, but an higher revision of the tech that the one used in 360 mainframes. Derivatives of the original MST ceramic technology evolved to produce packages for the different controller and CPU silicon dies used by IBM very late in the 90's. In the UMMR site (in Italian only) they have a complete section dedicated to all the older IBM weird technology, from chip packaging to their characteristic fiberglass PCBs with the outer layer filled with a full board solder pad array (which looked like prototypes, but were actually production boards).
