I’ll add the first page from my ComputerLand price list when I was shopping for a 5150. My purchase resulted in my first bank loan!

I recall at one time there was a SCSI drive option that included a ROM chip to insert into U28

I never knew you could order an 5170 without a hard drive.

I believe Zeparras had mentioned the external mounting was temporary while he debugged the physical connections. He was looking into a future mod of abandoning the Gotek case and mounting the board internally. Also, even with a functioning CF, some apps will stubbornly look to drive A: for...

That’s a nice board. I also have one, matching my s/n109596. I’ve replaced the rubber/foam on this one and also two later ones. They were all severely degraded and crumbling. Good to do as part of a thorough cleaning.

CGA was the the go to for anyone wanting APA graphics. It took some time before other options became available and there were compatibility issues. Back in ‘81-‘82, 640x200 APA was pretty impressive. An hour later, you’d return to your PC and see that amazing plotted factual! :)

A more valid production date is sometimes ink stamped on the inside of the front bezel. I accidentally damaged a datestamp on one of my RevA systems while cleaning it. :/

Thank you for jumping in, your knowledge on these is awesome.

I wouldn’t think your XT Enhanced boards membrane would be interchangeable IBMs InfoWindow board. Its additional function keys would of course require a more complex matrix and with all the work involved, would it be worth the effort? Better to buy a replacement membrane from Unicomp or, better...

'...seems to actually be two editions for DOS 1.0" I remember the news media back then making a big deal about how IBMs new computer can't add. I think the modified DOS 1.0 appeared shortly after that. COMPANY NEWS; Flaw in an I.B.M. Computer

I didn’t see a 5 1/4 floppy in the first NEC picture. Above the CD Roms is what looks like a 3 1/2.

Things have progressed really well. I was trying to read the bank 0 RAM chip dates from one of your images. Interested to know roughly where they were, supply wise for that early 8587 s/n. One of the early ones I have is s/n 9596 and the bank 0 RAM is dated 8140. Unlike yours, the...
