This would be nice to replace some things on my Model 30 8086 system.
Using the lotech 2mb EMS card and XIRCOM LPT network adapter.
I waaaaant :)
Plus with my new riser card from Peter Basset, my EMS card hangs off the back side of it. A good place for a PicoMem board instead :P
Sorry this is a revisit of an older post I made recently... but I think now this is a bit more direct, now that I have something in my hand.
No other MFG I talked to would help me out that were recommended in the old post.
Sooo......
I am working with an IBM Model 30 8086 system. Which has...
Worked with A friend of mine to come up with these.

Front USB Panel Bezel Cover @ https://www.thingiverse.com/thing:6221068
I know I am not the first or last to probably do this, but was fun to anyways, so thought I'd share ....
My 2nd IBM Model 30 I got last week, the power supply died last night.
Ordered an ATX to AT adapter and Converter to get -5 volt out from Amazon and it was at my door step by lunch time. (...
So far so good!
Some test values... All 3 are in the system.
ISA>USB - CH375 / FreddyV Drivers ( 1gb USB thumb drive )
Write Speed : 240.98 KB/s
Read Speed : 282.49 KB/s
8k Random, 70% read : 12.7 IOPS
Sector Random read : 21.2 IOPS

PS2XT2SD ( 32gb...
Thats about the only thing I can think of too I guess... Stinks cause I got so many of these 8gb cards never opened/used sitting in a box for the past decade.
They work in modern computers... The two Model 30's are my only retro systems.
I'll run MediaTest tonight.... I did make a batch file...
Ok maybe things better now.
I looked for the 100th time and finally... found the 512mb and A 1GB CF card from 20 years ago... found in basement in a box of crud thats been sitting for 5 years since I moved here...
Using the 512mb CF card now.
It has been running off the booted C drive for 20...
Smaller 115mb partition did not do much difference.
Still freezes eventually. Can sometimes add/delete files.. run chkdsk.... but sometimes not.. and freezes.
On either system.
Only other thing I can think of is getting another CF as mentioned... sadly only have a few of these 8gb cards...
Kinda works.... used Oracle Virtual Box to stage it up.. which made it 2gb in size.... ugh
Boots now... but when i try to create a folder or copy a file to it... freezes :(
Going through process and make it much much smaller drive size.
I was hoping to do just that tonight.... I have A 1GB CF flash card from like 20yrs ago.... from my first digital camera. But finding it is being problematic.
Did find this @ https://www.lo-tech.co.uk/wiki/XT-CF-lite_FAQ#BIOS.2C_Flashing_and_Reflashing
Where it mentions the IBM PS/2 Model 30-286....
This isn't A 286.. but the 8086 model. But I ponder, if it is the same problem then.
Disktest freezes up system. Don't see any output from it at all.
Hard drive test in CheckIt .. freezes also. On both systems.
I guess just don't work in Model 30 systems? or something odd going on...
Original 8086 CPU back in.
No other ISA cards installed
Changed around the jumpers on the XT-CF-Lite acrd...
Same issue. Sticks after the Starting MS-DOS message.
I will see about running DiskTest and see if anything happens.
Greetings.
I have A two IBM Model 30 systems.
Both have NEC V30 CPU upgrade,8900D video card, CH375 ISA>USB Card and the GoTek Flash Floppy setup.
I have the PS2XT2SD in one system for weeks which has worked great.
I have another one coming but for now was going to try the preassembled...
Maybe where ChatGPT-4 comes into play. Was messing with it just now for Turbo Pascal ( my world ) and was able to come up with A number of assembly routines for populating off screen areas in definable chunks.
Then being able to copy any of those chunks off screen, to the visible screen quickly...
Not sure if was getting at using the video ram as a replacement for EMS. Since be under 1mb of available anyways. But using past 256k for anything of any sort that maybe could "help" in some way.
I think 286 systems could see ram speeds of 70ns to 120ns? maybe a little quicker/little slower...
