It does! A 42 Mb Seagate :D...ST-151. Its a late model XT it seems but I have yet to do a full deep dive on it.

Wow a ST-251, these were built to last :D and no need to fuss with parking it, the ST-251 parked the heads by itself upon shutdown, not to mention its unique startup sound (some sort of hollow knocking noise, once heard never forgotten), IMO it's a real keeper!

Just received some DIY goodies from Tiido to maximize my mega-pc:

Image

- 4x 4MB/60ns simms for a total of 16MB
- 3x 12ns SRAM for a total of 64kb
both the max supported by the system

excellent stuff - just need to solder :)

30-pin SIMMs suddenly became rare enough to justify new manufacturing?
Well, the 16 MB variety surely is rare, but 4 MB?

If you are in USA the 4MB 60ns sticks are pretty cheap to get but pretty much nobody sells them in EU and buying from USA will end up more than twice the cost due to ridiculously high shipping costs over there and import taxes that come on top aswell.

They're not yet for sale but soon will be. Keropi helped to make it happen so he got first dibs lol

Still no keyboard though...but it works!

Congrats on the find, it's in great shape too!

I thought about making my own custom SIMM30s a few years ago, but my interest in particullar systems, that were using these SIMMs, dropped, so did the motivation to make the PCBs. Which PCB manufacturing company did you choose to place an order, Tiido?

Are you going to make 16 MB ones as well?
There may be some demand: for AWE32, late 386, many 486...
And they are rare - in Poland, I've only found them for 77 USD/pair.

16MB ones I'd like to do but there's difficulties sourcing parts for them, these very large DRAM chips are uncommon and quite expensive but definitely not 77usd/pair expensive lol.

Just bought this last week and a new motherboard for it yesterday. PSU jack on 3 layer motherboard was having issues, and needs a hinge fix......epoxy time.

1994 NEC Versa 40EC
- i486 DX-2/40
- 8MB of RAM (4 onboard, 4 on exp. card)
- 1.44MB Floppy
- 250MB HDD
- WD 512k SVGA on 7.5" color LCD ( working)
- 2x PCMCIA slots
- orig. Power supply
- probably the original NiMH battery

Issues
- cracked hinge mount on top cover....probably from overly stiff hinge mechanism

- bad system board in power section. Would try and power on after 1st reassembly (Status LCD showing battery symbols in various states). Found a replacement for $20...but keeping the old one to attemt to fix as well. Did boot twice without HDD, FDD, or Battery, but stopped once position changed. Seems the problem is jack related (burned cont pin on jack on laptop per charger pinout & Versa P svc manual).

Future Plans
- 16MB memory card
- 80 GB HDD
- new 2430 CMOS battery
- new or rebuild Suspend Battery
- new or restore main battery
- PCMCIA LAN
- PCMCIA wifi
- carrying case
- FreeDOS with WFWG 3.11
My DOS Boxen
85' Tandy 1000(a)- 8088/4.77, 640K, 8gb XT-IDE, TGA, 3-voice
89' GEM 286 - 286/12 w/287, 6MB, 1GB SCSI, 2XCD-ROM, ET-4000 1MB, SB Pro2
Creeping Net 486 - 486DX4100 WB, 128MB, 512K L2, 15GB+40GB, S3 809 2MB VLB SVGA, SBAWE64

Ahh, so they are more common in Macs than in PCs, right?
That would explain their rarity in this area - Apple stuff was almost non-existent in that era.

72-pin SIMMs cost pennies.

And all of those links have shipping cost that lingers around 30usd+, and once they arrive here I'll have to pay 20...30usd in import taxes, so it makes them completely uneconomical, to a point it is much cheaper for me to make my own. I imagine shipping won't be much different for other EU countries and import taxes probably are similar if not worse also...

Nice! I love these old(ish) DOS laptops, have a bunch meself, including slightly newer NEC Versa 4050C.

What is the LCD on yours, though? Is it TFT or DSTN?

We have the same problem here as well - shipping+tax just make it not worth. Tiido's solution is a most welcome one for EU people.
