I'm having bit of fun with my various CP/M systems but I ran into
what I see as an interesting problem. I got Turbo Pascal on two
systems. A TRS-80 model 4P running Montezuma Micro CP/M and a TRS-80
Model II running Pickles & Trout CP/M. I tried to compile the version
of Kermit written for CP/M using Turbo Pascal. On both systems it
runs out of memory and crashes in the same place. Surely the developers
would have noticed this. Anybody here have any experience with this?

Has anyone communicated with or know a way to communicate with Joe Rigdon
out of Florida? Most here should know him as an old-school ClassicCmp
veteran.
If anyone has any information at all on the whereabouts of Joe Rigdon, and
for that matter John Lawson, please either reply here or to me privately as
appropriate.
Thank you.

I have a Dell Vostro.
When I boot, the screen briefly flashes and then remains dark.
I have another one on which the screen would stay lit for a minute or
two, then go black. If I closed the lid and opened it, it would stay
lit for a few more minutes, then go black again. I corrected that by
replacing the backlight power supply.
In this one, is the problem more likely a defective power supply for
the backlight, or a defective backlight, or something else?
Thanks,
Van Snyder
The DEC VT340 has a slot in the back of the terminal to insert a ROM
cartridge. I can't find any description of what this DEC labeled ROM
cartridge would do for you. I've seen them with V1.1 and V2.1 markings,
does anyone remember what additional capabilities these ROM cartridge
provide?

Vintage computer enthusiasts might want to keep track of where to find
CRT-based analog oscilloscopes, for use as output devices.
The early MIT and Lincoln Labs computers used D/A converters to steer
and activate the beam on analog scopes to draw vector images.
Working on Whirlwind simulation, we've been able to get this technique
to work with "real" oscilloscopes, e.g., Tek 475, but we have not yet
found a single DSO that has X/Y _and_ Z inputs (let alone the required
phosphor fade).
Myself, I have a couple scopes with backups, so I'm not in the market
for another one. But others might consider the option...

I have more then I need. All the working ones are HP w/color crts, and as far as older, verifiably vintage tools (right down to the 680x0 processor in either) I have to admit I favor them as a brand. Call we an oddball, weird egg, badges I wear with pride.
But who could resist the allure of the newer ultra portable, even handheld units (some with bandwidth or sampling rates to 50mhz). I'm a big cheapo. But there's no real reason to agonize over a 65 - 200$ or thereabouts acquisition. It's a bit tiring to wade through the piles of availability. I favor a desktop unit, larger screen (but not always, careful). But most of those need wall current I think? The convenience of a handheld battery powered unit obviously has it's benefits.
I will always love and dote upon my color crt based HPs. But the damned things are so heavy, so unwieldy. Judy-Jude knocked my 54111d over, hit the paved floor, shook the house. And still works! Built to withstand an atomic bombardment.
Ifo you absolutely must run something old, yet don't want to deal with the complexities of modern emulation:
https://www.ebay.com/itm/191322319264
- drivers, whatever is needed, likely to be included on floppy. Ask seller. Not sure what tbe form factor it is. Who cares, nail it to a board or the wall.
https://www.ebay.com/itm/283869740055
- obviously a lot faster. 2nd cpu isn't necessary or necessarily beneficial, but it is mandatory (says me, don't be a plebe). Unlike the Intel S5000 series serverboards, this bad boy has a FLOPPY connector. Should boot dos. But I haven't owned 1 yet. Can't remember if I even tried to boot my s5000vsadimmr4 or whatever I had from a dos loaded boot cd. Just can't. But my board did boot Windows 2000. Not too shabby. No drivers or i/o plate with this though. Drivers for Win2k are on tne net. I even foumd a manual I think. Check with me if you have need. The Intel boards have support for Win2008. NOT this board afaik. If that matters to you.
Serverboards of this gen/chipset
have steemy hot ram. You can nail this
to the wall also. But have a desk fan to
keep it all cool.
Hi there,
I need a power supply for my PDP8F computer.
It is missing.
The PDP8F 19" chassis box came in 3 different depths,
600 mm (PSU front to back)
370 mm (PSU across the back)
300 mm (PSU front to back)
I need the shallow one, the 300 mm PSU front to back.
Do you have one available, or know where I can get one please.
Even if it is dead!
regards
ray
I'm looking for an HP 9000 Visualize workstation, like a B160L or B180L+.
I'll be attending VCF East in a few weeks so might find one there.
Has anyone used Cypress technology out of Clearwater, FL? It seems they provide a nice, fully configured to spec turnkey solution, but there's no doubt they charge for it.

Any better HP-specific forums or references would be appreciated!
Thanks
