Memory Expansion Adapters should help in identifying WHICH adapter... 512KB/2MB 286 Memory Expansion Adapter/A ? All use the same link... 1-8MB 286 Memory Expansion Adapter/A ? Expanded Memory Adapter 0-8MB XMA/A ?

XGA requires a 386SX at a minimum... no holy joy there... Image Adapter/A should work, but I'm not sure if you will have driver support. :(

AIX for PS/2 1.3 should sate your curiosity. I believe it is also on the Internet Archive...

A well-behaved ISA derived design should respond well enough to an MCA system. The MCA bus is set up to operate level-triggered, but if an ISA-derived card uses edge triggered interrupts, the IRQ circuitry converts it to level-triggered. Problems arise when a card of any derivation uses logic...

That's a thing. Looking at period adapters, oohhh... this can connect to a 100Mbit network... but the chipset is 10Mbit...

Did you mean to say "would MCA be able to allocate only part of its bandwidth to the ISA-derived card while it is active" ? There are a few different transfer types, all of which are derivatives of the basic transfer. MCA - Basic Transfer Procedure gives more details. All cards, regardless of...

This sounds reasonable.

Unfortunately, nobody made HSTR cards for MCA. "Modern" systems don't have support for TR. So, my fervid hope of running an Auto LANStreamer into a Madge Deskstream, taking the HSTR uplink over to a PCI HSTR adapter in a "Modern" system, is paradise denied. There were Fast Ethernet uplinks for...

Er, the granny low gear "basic transfer" is done at 10MHz, yes. ISA is maybe 16-bit [if that] over 8MHz [stable systems]. MCA transfers are not ISA. Wider [16/32 bit], less time to set up the transfer, much more flexible. Do not equate clock speeds between ISA and MCA. In ISA, the bus speed is...

Er, not true. Or, not exactly true. The drivers on the sysboard limit adapter-sysboard or adapter-adapter transfer speed. So if you dropped a Corvette into an 8580 [assuming you could "fix" the 2K NVRAM... ], it could run the 64-bit streaming mode, but talking to the 386 over the earlier...

Argh. Since I don't have either, further guestimation won't add much.

So. The business case [note the word "business"] was to sell to folks needing to engage in business. Not the hard-core gamer market [which didn't exist back then]. IBM sold [or tried to sell] reliability. Compatibility with business-related apps [accounting, word processing, etc] was what IBM...

Reference Disk Trivia and specifically, Copying Option ADFs to the Refdisk CORRECTLY

SGI IrisVision? Do tell. With what application? Pretty limited to CAD, IIRC. I DO know someone with the correct compiler, if you have a desire to code for it.

WSI6 Adapter Pinout sorta complete. Wow. Missing more teeth than a washed-up boxer... No IRQs [Polled?] No ARBs No ARB/GNT No TC [No DMA] 8 data lines, D00-D07 24 address lines, A00-A23

GE / FANUC WorkMaster Interface page is VERY incomplete, I don't have any WorkMaster Interface cards, nor do I use LogicMaster to control Series Ninety PLCs. I do have pics of the WS6AI IC647WMI620 parallel interface only [images from Mike Lycett]. WMI cards are also called the Work Station...

Auxiliary Video Extension on the Ardent Tool. A BVE card will NOT fit into an AVE slot. -BUT- it will work just fine in a normal 32-bit slot with the little video extension hanging free. Why is AVE on a 386 bit system on a 16-bit slot? Uh, you are pumping the raw, screaming power of 256 color...

Welcome to IBM... When documenting IBM PS/2s, I foundt the Announcement Letters are a good start. Warning! You will probably end up having to read each announcement, looking for references to other Announcement Letters. The Datamaster might have been called something other than DM. IBM...

Proxy server, yes. But I still want all the speed I can get... Unsafe at any speed...
